I've been working on this new TEK for a few months now, trying to perfect the process. I hope a bunch of you will try it and let me/us know how it goes. I think it's the next logical progression from the Laundry Basket TEK, because it completely eliminates the need to mist. The straw gets colonized inside a vented plastic tube, so the moisture and CO2 stays inside where it belongs. After the first few pins form(invitro), you cut the plastic off, and use it as a 'humidity tent' to allow air exchange while keeping the evaporation level under control, so the most awsome flushes can develop. I'll write the full TEK and post it here if anyone is interested. These straw logs produce the FASTEST and largest crops I've ever seen. The logs you see in the pix below were pinning on the 14th day after spawning with grain. The longest I've waited for pins to form was 18 days. Some were spawned with rye, and some with corn. I've made straw logs anywhere from 12" in length up to 72". The smaller ones are easier to handle, and I've stopped making them any longer than 24" for that reason. The six foot log weighed in at over 100LBS, and was very hard to move after full colonization without bruising the mycellium. The fruits form in a full 360 degrees around the log, so the yeild is incredible. You don't case, don't fan, and don't mist! The 48" log you see below produced 17 lbs of fresh mushies, including the 74 gram fatty, on the first flush, from less than a dollars worth of straw. It was spawned with 6 quarts of either rye or corn, I forgot which. (I've even mixed rye and corn together in the same log) The 72" log 'only' produced 18 lbs, because I damaged it quite a bit getting the plastic off.. After full colonization, they don't like to be moved, because if the log flexes, it bruises the mycellium. Try to let them incubate where they will fruit at. I incubate mine on a shelf in a 72F room. Enough heat is produced by the mycellium running through the straw, that if it was in much warmer of a room, it would overheat and kill the myc. The 12 inch log shown below has over 100 pins on it, so I think smaller logs are the way to go.
Full Colonization. Invitro pins forming. The two spots you see at the left that aren't fully colonized is where I didn't pack the straw tight enough in the tube. You want to really pack it with all your weight, so it's pressed tight against the plastic tubing.
A 12 inch log that has just been 'birthed'. Use scissors to cut the tubing along the TOP edge of the log, and let it serve as a 'tray' for the log to sit on. (you can cut another piece of plastic to lay loosely over the top to keep the humidity up, just be sure to poke lots of holes in it for air exchange) Also if you HAVE to move the log, use the plastic so you don't touch the log.
The same 12" log, 24 hours later.
This is a 48" log, 24 hours after birthing.
The same log, 48 hous later. Notice how the pins just exploded! I counted over 800 pins before I lost count. All on less than a dollar's worth of straw!
Here's a 24" log, on the second day after spawning. You can clearly see the mycellium growing out of the rye, and into the straw.
I'll post a full TEK if ya'll want. I have a pretty good method for pasteurizing the straw in my old rubbermaids. Hell, don't need 'em anymore for anything else! lol. Oh, and one more thing. I've only pulled 5 aborts out so far! For some reason, they don't abort on the logs. I don't know why. I've had ZERO contams, probably because the straw colonizes so fast, and this is in a house with wall to wall carpet. Hell, I even build the logs on the kitchen floor. Can't think of a worse place, but it's all I have.

Nice! I'm interested to see the full tek.

I noticed your explanation in another thread. Do you know a source for the plastic tubing where you do not have to buy in bulk? 8 cents a foot is great, but I doubt most people will want 1075 feet of the stuff. Did you experiment with thinner tubes?

yay! matt

Thanks guys,
It'll take a few days at least to write the tek, so bear with me. I'll try to answer a few questions about the process in the meantime though. The tubing came from WW Grainger. Part number is 5ZW54. Most US cities have a WW Grainger. It's mainly for industrial customers, but they sell across the counter as well. Also try Yes, you have to buy 1,000 feet of the stuff, but $85 is a small price to pay for a lifetime supply of the material. The diameter of the tubing I bought was 8". It's also available in 10, 12, and 16. I'd be afraid of going too thick, as you don't want the core to go anerobic on you. I think 10" would be fine though. Be sure to get the 4 mil thickness. The cheaper 2 mil won't cut it. You have to really pack the straw tight in the bag, and you'd rip the 2 mil bags before you got the straw packed tight enough. I originally planned to stand the logs vertical, and actually had them hanging from the ceiling. Paul Staments shows that system for oyester mushrooms in his book. I was hoping the pins would form at the vent holes I cut in the tubing, due to the air exchange, but no such luck. Pins formed EVERYWHERE!! There was no way (that I could see) to keep the log vertical out of the bag, so it became a horizontal TEK. It might be that a guy could place a piece of chain within the straw, and use this to hang the log from a hook in the ceiling. Might be risky though. The chain wouldn't have a bite until the mycellium was fully colonized through the links, and then if you bump it, you'll bruise the myc. One other point, be sure to chop the straw into very small pieces. Consider any length of straw longer than your fingers as too long. 1"-3" works fine. I'm using organic barley straw from the local feed store. It's $4.50 for a 50lb bale. Wheat straw should work just as well, it's just that in this part of the country, the farmers seem to grow barley.

There are tons of places to buy poly tubing.
What do you think of these bags. they have sizes that you have reccomended.
items: 164812, 164815, 164818.

For example on the papermart site 1000, 8" x 12" bags 4mm thick is $38.83.

There are also sites ive seen that have reclosable ziplocks poly bags.. What do you think?
By rodger rabbit (Skyypilot) on Sunday, April 13, 2003 - 03:29 am: Edit -------------------------------------------------
The problem I see with those bags is that they're flat. Also, the length isn't enough. You waste a lot of tubing tying the knot in both ends. I cut the tubing 18" longer than I want the log to be. That way, there is room to tie the knot at each end, and have a 'tail' left over to handle the bag by while it colonizes. Try I believe they sell a similar tubing, and you can get it in 20' lengths from them. It's a lot more expensive that way, but if ya just wanna check the system out, it might be a way to go.
By Blycat (Blycat) on Sunday, April 13, 2003 - 04:07 am: Edit -------------------------------------------------
They have 8"x20" or 9"x24" or 10"x24"
The one end you wouldn't have to tie.
Doesn't matter. I don't want to take away from people talking about the TEK.

By Jorneyer (Jorneyer) on Sunday, April 13, 2003 - 05:18 am: Edit -------------------------------------------------
Here is my suggestion; it is just that. Regarding the hanging of the log-- if you could put this around the log while still colonizing, then you could cut the plastic away after you hang it. Is the log sturdy enough to stand on it's end like this?
By F. Ungus Fox (Fungitodd) on Sunday, April 13, 2003 - 05:35 am: Edit -------------------------------------------------
Simpler yet...

Why couldn't you take some 1/4" wood dowel and cut it into say 4-6" lengths (cut 4 pieces). Then poke the dowels into the side of the log towards one of the ends. Place them 90 degrees apart, and you've made a tripod for the log; which will support it in the vertical position.
By rodger rabbit (Skyypilot) on Sunday, April 13, 2003 - 05:46 am: Edit -------------------------------------------------
Hey....I like both ideas. My preference is to have the logs vertical. They can stand on their own just fine, if ya can keep them from tipping over. Need to find a way to keep the log wrapped loosely with plastic though to keep it from drying out on the surface and killing the mycellium. Jorneyer's idea would be great, as the rope or cables could keep the plastic away from the logs. Keep thinking guys!!

By rodger rabbit (Skyypilot) on Sunday, April 13, 2003 - 06:38 am: Edit -------------------------------------------------
It's the first pic in the series. The one by the dollar bill. And it's not much bigger than the 'average' from the logs. The larger logs seem to make bigger mushies, but are more likely to take damage from being moved around.
By stevie ray (Gldfsh) on Sunday, April 13, 2003 - 06:54 am: Edit -------------------------------------------------
when do you think you will have the tek ready to post? Also i was thinking i have a 31gal maid and if you took something like that and stuck 8 skewers (metal) through the bottom of the tote and stuck the logs on the skewers using one foot logs you should be able to fit 8 upright logs in that container and if they performed as weel as your 4 footer then that would be double the amount 34 lbs fresh in a 31 gal tote! just plain crazy!!!!!!!!!
By rodger rabbit (Skyypilot) on Sunday, April 13, 2003 - 07:32 am: Edit -------------------------------------------------
I don't think 4 12" logs would do as well as one 48" log. The smaller ones are just easier to handle. Larger substrate=bigger mushies.
Don't forget to leave room for the mushies to grow on the log either. Also, I'm just not a fan of terrariums. Just about everyone who uses them has contam problems, due to poor air exchange. I think the best use for that maid, is to hold the hot water when you pasteurize the straw. I work 12 hour shifts, so my time is limited. (and why I needed to be free from misting/fanning) I'll work on the tek when I get home from work. Give me a couple of days. I'd like to document the whole process for everyone, including filling the tubes with straw. It's important for folks to know just how tight you pack the straw into the plastic. I've even thought about putting my feet in the tube so I could jump up and down on the straw! Sure is good to see everyone thinking. That's how we improve our hobby.
By Scientician (Scientician) on Sunday, April 13, 2003 - 02:27 pm: Edit -------------------------------------------------
Absolutely amazing, this type of ingenuity was what made this country.

Have you been starting your grain with multi-spore inncoulations, or clones? Any noted positive or negative effects on potency?

You said you've had no contams, which you believe is mainly attributed to air exchange. Do you have any type of air purifier running, or is it just room air?

I should have a fun time finding organic straw, wonder if the co-op will have that!

Brilliant, just brilliant.
By rodger rabbit (Skyypilot) on Sunday, April 13, 2003 - 03:48 pm: Edit -------------------------------------------------
There's a bit of controversy on these boards over the multi-spore inoculations, vs. prints or clones. A multi-spore innoc gives a pretty good chance of fruiting for someone just starting out, without the means to do agar work. The problem is, a print or syringe will produce literally hundreds, if not thousands of strains (or sub strains if you will) all competing for space in your substrate. That�s why there can be so much difference in size, shape and potency of the mushrooms from a single casing or cake. It�s also why the first, second, and third flushes of many of the commercial strains look so different. They ARE different. If you can isolate a single strain on an agar dish, you can then fruit it in a substrate, and it will have free reign without competition for space. Cloning will give you a single strain as well. The problem with cloning is that any living organism can only divide its cells so many times, before �old age� or in the case of mycology, senescence sets in. I use prints, and swipe the spores with a scalpel directly onto the agar. Within two days of germination, I transfer a tiny piece off the leading edge of the growing myc into a fresh Petri dish. Watch for the myc to develop on the dish and form a series of �fans� around the center of the growth. Each of these fans is a separate strain. Transfer a tiny piece of myc from each �fan� and label them 1,2,3 etc. and see which is the best strain. Then just grow it out and fruit! Mycelium is so fast growing, you could take a tiny piece of myc, the size of a grain of rice, from a Petri dish, and grow it out to over a million pounds of fresh mushrooms in six months or less, assuming one has the facilities to do it. Grain to grain transfer is the key, as well as staying ahead of senescence. That�s how the button mushroom industry makes money selling for less than a dollar a pound.

Or you could keep the log horizontal, but elevate it.
Take 4 dowels and stick 2 of them in a V formation on each end of the log. Then you would have a little "straw pig".

As for packing the straw-- could you find a chunk of plastic sewer pipe with the same inside diameter? It's usually green and laying around big constuction jobs. Then put the plastic inside and use some kind of smusher to pack it down. Like they use at McDonalds to pack the trash down. When it's all packed slide it out of the pipe.

By Blycat (Blycat) on Monday, April 14, 2003 - 01:59 am: Edit -------------------------------------------------
Here's a link to another doing the same kind of thing.
By rodger rabbit (Skyypilot) on Monday, April 14, 2003 - 02:13 am: Edit -------------------------------------------------
That guy is growing oyester mushrooms on his logs using the method Paul Stamets developed, and describes in "Growing Gourmet and Medicinal Mushrooms". It's what I started out to do, after reading Paul's book. Only thing is, Cubies aren't so cooperative about fruiting only in the holes you cut in the plastic. They want to fruit everywhere, so the plastic has to be cut away. That's why my logs ended up horizontal on a shelf. To answer Max's question, to keep the log hydrated after birth, I leave the plastic I cut off the log under it and wrap it around towards the cut. Just keep it loose. Cut another piece of plastic, and lay it over the top of the log. Be sure to poke lots of holes in the plastic for constant air exchange. All you're trying to do is slow down evaporation long enough to allow the log to fruit. The mushies will push the plastic out of the way as they grow, and it won't bruise or hurt them in any way. (contrary to misting, which does seem to bruise the fruits) I only flush em once, then use the straw for mulch in the garden.

may I modify tek a bit? an alternative to cutting away plastic and letting fruit on shelf, if your using straw and manure (ideal compost material), couldnt you just dig a hole outside and plant the log? its big enough to spawn its own mycelia network.....right?

I must say that once the vertical/hang issue is hashed out there will be nothing stopping folks from hanging these babies from shed rafters like smoked hams
would a chicken wire cage be of any benefit? if you could get the log packed into a pvc tube and a wire sleeve to push the log out into?

I love all the ideas!! I'd prefer to have the logs standing vertical, but I had trouble with that, so ended up with horizontal logs on a shelf. I'm in the process of writing the tek for horizontal logs, because I KNOW it works very well, but encourage all to experiment and try to find a good way to hang the logs. They'll take up so much less space if they're hanging from a ceiling joist, and if they can be spun around, picking will be a breeze too. So far, I like jorneyer's idea, that he posted the drawing for above, and I'll be experimenting along a similar theme. The main thing is to get some more folks packing these logs, so y'all can see for yourselves the huge shrooms these things grow. I start 4 days off work tomorrow, so should be able to do some writing, if I don't get too 'hungry'.

Just gotta think my way around that damn plastic tubing - I did a search and found one of hip's old teks for using the same principle and stuffing the straw into 1/2 pint jars, but I don't think they're big enough to hold the moisture neccessary to leave out the terrarium and fruit in the open air - that's the part that gets me all hot and bothered . . .

hmmmmm . . . . gotta be a way around buying $85 worth of tubing - I'd do it, but I don't have a Graingers nearby. Think solly, think . . .

So does that mean that the only function of a casing layer is to hold moisture? I mean why is casing necessary in all other instances I have seen except this one. I tried to fruit a vision's basket by removing it from the laundry basket and flipping it. Since the bottom is mostly covered with plastic, except where you poke holes, it gets totally covered with mycelium. But I got contaminated. for rabbits and all!

Then cover with clear garabage bag with 1/2" holes 5" O.C.. Anyway, just our .02 cents

ok so dow rods might not work.. but stiff plastic tubing would... The point was to stick something through the top of the straw so it could be suspended... So whatever material makes the most sense that would do the job should work.

I'm thinking the myc running through the straw is strong enough to hold the log...

By rodger rabbit (Skyypilot) on Tuesday, April 15, 2003 - 03:14 pm: Edit -------------------------------------------------
I think it needs to be external support. I wouldn't want to hang that much weight from the mycelium. A 36" log weighs 50 lbs. I'm thinking a suspended shelf, upon which the log could stand on its end. Keep the ideas floating.

This is a VERY FAST tek Babooscha. (are you a Russian grandmother? lol) Quart jars, spawned by grain to grain transfer are fully colonized in 10 days. The logs are usually done fruiting within 3 weeks of spawning with grain. That makes 31 days, from knocking up the grain, to picking mushrooms off the straw.
By Goose (Fathergoose) on Tuesday, April 15, 2003 - 03:40 pm: Edit -------------------------------------------------
Mushroom Zens idea with chicken wire cage, plastic or metal dowels inserted 1/4 of the way down the log.Then place it in a plastic garbage can (35 gal. maybe), let the dowels rest on the top rim of the can. cover with plastic with holes in it. you could put holes in the garbage can also for air exchange.

Be a little harder to pick, but then on the other hand maybe the crop would favor the top where the light is.

You say the log needs external support because when fully colonized, it weighs a lot. When I saw Sno's idea with the dow rods crossed through the top as a hanging apparatus, it gave me an idea. I had to reach deep into the vault for some old physics knowledge. In short, I thought of spring force vs. gravitational force. I drew up an idea that is a spinoff of Sno's with dow rods (or some other support beams) crossed through the top and the bottom end of the log. Now, the top for protruding beams can still be supported by twine or cable and suspended from the ceiling. But the bottom four supports can be attached to long narrow springs which should also be attached to the ceiling. This will reduce the force pulling on the top end of the log to prevent the top tearing off.

The only thing you need to consider is the strength of the spring. So you have a 50lb log that is at a length "x". If you put the top supports are placed at 1/5x down the log (or wherever you choose) then you still have 4/5 of the weight hanging on the bottom. So you need enough spring force to counteract 40lbs of force pulling down. You will have to figure out how to calculate spring force to length but as long as you can get negative 40lbs pulling up on the log it will balance out and not tear! (hypothetically)

I haven't built a log and I don't know how damaging this idea could be. Physically however, it will work to maintain vertical support throughout the log.

Just my 2bits. Hope it helps spawn new ideas. I'll try post a drawing if anyone is interested.

wow... amazing tek... =D I have an idea on how to hang the log so that it has maximum fruiting area, but im not sure if it would present contamination problems... take plastic mesh (like the stuff xmas trees are wrapped in), sterilize it, tie or seal off one end somehow, and place it inside the plastic bag. Make sure the mesh is a lot longer than the plastic. THEN pack the straw etc. Tie the mesh/plastic off, then tie the remaining mesh to a vertical support (hook or something). Theoretically the mesh will provide extra external support for the uncolonized log, and after full colonization the plastic can be cut out from around the mesh... another sheet of plastic will be necessary to cover the log while it fruits. You could prolly put support under the log too if there is too much pressure.
just a little brainwave... =P

Why not just take some wire like a fence that would look like T-T-T and wrap it so the top and the bottom of the T connected around the log, then hang it. Sorry if my explanation is poor but I am sure that the wire would give it enough support to keep it from coming apart and it would leave the maximum amount of straw exposed as possible. You could loosely wrap plastic around it or drape a huge clear garbage bag over the top to keep in humidity. If anyone understands what I am saying, maybe you could draw a diagram to show what I mean better. Or you could wrap wire around the log like it would look in the middle of a spring. Sort of like what it looks like with your arm in the center of a slinky. Then just tighten the curls at the ends so it wouldn't slide, to keep it stable. Then just hang it from one end. Any idea why that wouldn't work?

Like this?

Here's my shot at how to hang it up. It's pretty much the same as Jorneyer's. I don't like the idea of plywood so it's changed to some kind of PVC cap or tupperware bowl. Also the depth of the cap will allow the log to sit more safetly. Obviously the least amount of depth as possible would be best as to not cover up surface area of the log. Strings or rods will be used to attach the two caps together. If the length of the strings are made slightly longer than the Log, than the LOg should sit in nicley.

o.k. Here is my problem with hanging the log by a wire . It will sway giving the log more stress and a higher chance of breaking apart. What I was thinking is building or buying a shelving unit that you can change the distance between shelves to fit your needs. (depending on the size of your log) Now you will need to make two metal stakes (i.e. skewers preferably something that won't rust) and attach thru the shelves the bottom one pointing up and the top on pointing down. I think 8-10" should be good for a 3 ft. log. Now borrowing part of Bly's idea get two 10" pvc caps, drill a hole in the center and slide one over the bottom stake. Then slide the log onto the skewer then put the other one on top of the log holding the log slide the top shelf down onto the log sticking the skewer thru the center of the log. Secure the top shelf and there you have it. Depending on the shelf you could do more on each shelf. The purpose for the pvc caps is so you can spin the log when it is time to harvest. You could do it without the pvc caps but i don't think it would spin.
What do you guys think?

I am not crazy about plywood either, blycat. I think it would rot and breed mildew. But it is cheap and plentiful, if the user wanted to paint it.
A really big stainless steel mixing bowl would probably match your concept, without breaking.
By rodger rabbit (Skyypilot) on Wednesday, April 16, 2003 - 06:37 pm: Edit -------------------------------------------------
Plywood would work fine, and I'm gonna try it. Just put a plate or something between the straw log and the plywood. The log can support itself from one end easily. (the end it sits on that is) I like your drawing Jorneyer, Something like that with a plywood disk top and bottom, with threaded rods with washers and nuts to connect the two disks solidly together would be great. Perhaps pass the all-thread rods through pvc pipe, so the sharp threads don't ever touch the logs. I've seen the logs start to dry out a bit, and the last few mushies seem to be smaller. I think I'm gonna build a log with an inner resevoir made outta 1/2" pvc with a hundred or so small holes (1/16") drilled in it. It would be placed down the middle of the log during construction, with one end capped, and the other end left open so a coupling could be slid on after the bag is birthed.

that threaded rod is called 'reddi rod' and it may even come in stainless form. Usually in 36" lengths I think. Grainger would have it.

I was thinkin, and this is what I came up with. Find some rod to the length of what your tube will be. Conduit probably will work. Get a board that is thick enough for the weight (1/2" to 3/4") and big enough to support the log on one end. Drill a hole in the center of the board large enough for the rod. Put either a washer and nut on the bottom of the rod, or some other attachment (collar of some sort) so the board will slide down the top rod to the bottom and stay in place. Take the top of the rod and come up with an attachment to the ceiling. You could put a swivel joint for easy harvesting. Pick up freshly made tube, and carefully slide rod through center (try hard to stay in the very center) of the tube. The bottom board will support the weight, and the rod will keep the small horizontal force balanced, as long as it is in the center of the log. The plastic will keep it together until the mycelium takes over.

By rodger rabbit (Skyypilot) on Saturday, April 19, 2003 - 07:50 am: Edit -------------------------------------------------
Ya gotta cut a few holes when you make the log, to provide air exchange. Paul Stamets recommends an arrowhead, and that's what I use. Poke holes every 3 inches or so. That lets the CO2 out, while keeping (most of) the moisture in during colonization. They don't fruit just at the holes though. You have to cut the plastic off after the first few pins form, so the fruits can grow. The first log or two I built didn't produce much better than the first vision's laundry basket or two I did. I found out the hard way, that you MUST chop the straw up really small, and you MUST pack it down really tight. With those two lessons learned, success arrived.

Rabbit, It was a hopeful idea, but as I was stuffing the 30" donut it became apparent that it was just to much work, I ended up exhausting about an 1/8 of my bale of straw, and cut it up by hand into pieces an inch or less in size. so Basically I've got about a 38" sausage I inoculated with 8 pint jars of brf. One tip for anyone wanting to cut straw small and fast, keep the straw in the bale all tightly packed the use a large serated knife and slice of inch sections like carving a turkey. Anyways I hope it all worksout....I'm sure theres going to be a windfall of log pics in about 3 weeks.

That looks like the stuff, but I didn't see a price. The 27.20 is 'height' Also, it looks like they sell it in 'width', which is probably the lay flat width of the tubing. The 'lay flat' width is 1/2 the circumference. You'll have to adjust the figures. I'd go with 10" diameter. Now, since (pi)D = circumference, you want 3.14 x 10 = 31.4 The 'lay flat' width would then be 1/2 that(15.7"), or 16" which is the closest match. Somebody check my math. It's beer:thirty here.

Rodger, are you getting multiple flushes from these logs? My past, somewhat limited experience with uncased straw was that it was a one hit wonder, no further flushes to speak of.

Great innovation, just seems like a lot of work if you only get one flush. Still, it's a great addition to library of methods now available. Thanks.
By rodger rabbit (Skyypilot) on Wednesday, April 23, 2003 - 07:09 am: Edit -------------------------------------------------

By rodger rabbit (Skyypilot) on Wednesday, April 23, 2003 - 10:18 pm: Edit -------------------------------------------------
Looks good. Just find out if the sizes are 'lay flat' width, or diameter of the tubing.

You can dunk and get a small second flush. It's just that straw pretty much uses up all it's energy on the first flush, and you're better off starting a new project.
By Mycofile (Mycofile) on Wednesday, April 23, 2003 - 10:54 pm: Edit -------------------------------------------------
Yeah, I hear you. But just for further thinking on optimizing what already seems like a kick ass method, I bet it doesn't use up all of it's energy, but rather it is a moisture related problem.

My reasoning is that 50 pounds of straw, with comparable surface are, if cased in a tray would yield several if not many flushes. Assuming contams are kept at bay of course. So, we know that there is enough "energy" in the straw, as long as moisture is more available.

My guess is that dunking for a second flush isn't as productive as the first not due so much to a lack of moisture however. I say it's more due to mycelial damage due to drying during first flush.

Possible solutions (again assuming one isn't happy with the method as it stands).

1. Gradual supply of moisture, provided by some type of moist core (verm possibly). That would be pretty hard to build into the log though. Perhaps a small diameter perforated pvc tube could be centered in the log as it's made, and filled with moist verm. Or just a normal pvc tube centered in the log as it's built, then filled with verm, then remove the tube (assuming things aren't too packed to remove the tube at all). More trouble, but could allow for multiple flushes.

2. Some type of slow "drip" style irrigation. Stamets mentions these briefly in one of the books, but gives no specifics that I remember, nor heavily endorses the idea as very promising.

3. Intermittent contact with moist perlite from below. When I grew cakes, dunking hadn't been invented. I rehydrated cakes by setting them directly on moist perlite until the second flush pins came in. If the cakes weren't removed from perlite at that time, fruits were soggy. Perhaps if the log could simply bet set on perlite for a few days post harvest, and removed as soon as new pins were spotted, second flushes would be better.

4. Some way to keep the humidity higher throughout the growth period. Like cake conditions. 99% humidity. Even at this, you would still likely have to rehydrate via perlite or dunking based on my previous experience with un-cased straw. Also, you would likely loose the beauty of this tek's no terrerium, open air, low contam virtues.

5. Scratching. Not related to moisture really, but damage from drying surfaces. Cakes which have drying damage can be encouraged to fruit more by thoroughly roughing up the surface with nails or forks. Scratching is also commonly practiced when growing oysters on uncased straw. As in number four, I'd combine this with dunking or some other rehydration method.

6. Maybe come up with some type of a double ended casing type idea? Lay the log on a ridge of moist verm, maybe even run a small ridge of verm along the top of the log. Not sure about this one though, just brainstorming.

7. Or, this is a big or, go back to what made the PF tek so successful uncased. Mixing moist verm in with the straw. You could add a lot of verm without really diluting the nutrient density of the log as the verm would fill in spaces between the straw for the most part. The verm could even be saturated with a contam resistant, pasteurized nutrient, such as worm casting tea, to provide even additional nutrients. This idea has lots of promise if successful, but it also switches things around radically with the core principles of the method and all...

Just seems to me that most people when trying this for the first time might as well try for a second flush. I understand that once you get a hang for it and have your systems up, you might as well just replace the logs with fresh ones, but most people will have some lag time there on their first attempts before they have a second log ready to replace the first one.

What do you think rodger? Have you tried any of these other methods? If not, what sounds promising to you?
By Hippie3 (Admin) on Wednesday, April 23, 2003 - 11:18 pm: Edit -------------------------------------------------
i'd bet a good long dunk would be the easiest and most effective option. that alone often triggers new mycellia and i'd agree, there's still plenty of nutes left, the grain alone is still largely untapped.
By rodger rabbit (Skyypilot) on Wednesday, April 23, 2003 - 11:40 pm: Edit -------------------------------------------------
I'm working on an inner res tek as we speak. The only reason for this is that I've noticed the last few mushies are a tad smaller than the first, due to drying out of the log. The problem with even trying for a second flush/dunking etc is that it's nearly impossible to move the log without damage. It has no container to hold it rigid, so if you allow the log to flex or bend when you move it, you tear the hell out of the mycelium. The other problem is that after a flush, the mycelium naturally declines in vigor, and this allows the contams a chance to take hold. I think it's just more efficient to get rid of the log after first flush, and have a second one coming along right behind it. You're not wasting the log...Put it in your garden as mulch. Prob get an outdoor flush in the fall.
By Hippie3 (Admin) on Wednesday, April 23, 2003 - 11:42 pm: Edit -------------------------------------------------
a variation on the above.
what if...
one took a section of plastic pipe, say 4-6 inches in diameter and 2-3 feet long.
drill several holes over its' length for ventilation.
stuff with straw layered with grain from one end to the other. one could really pack it in tight.
like your log but in a pipe instead of a baggie.
just a thought...
or was that option already mentioned ?
kinda stoned right now...
sems likely once fully colonized you could slide it out of the pipe...

Give it a try! One thing. How will you know if it's fully colonized, unless you can find clear pipe? I actually thought of doing one of those to look like a xmas tree, using lots of tee's and 45's. Was gonna drill the holes with a 7/8" hole saw, so the fruits could come out the holes. Just leave it in the pvc. If ya use black pvc pipe, then it should only fruit at the holes where there is light/air available. Sounds like your case of the 'mad scientist' is flairing up again hip.

I followed up with - item TC4-8 (gee I'm obsessed w/this plastic tubing). It's $52 per roll. Turns out the "height" is supposed to be "weight." It's a typo. As the shipping weight of this is 27.5 lbs. and that of Grainger equivalent is 28 lbs (their catalog), I'll bet it's the same stuff. Also, it is 8" diameter. I'm still not sure I need 1,075 feet, though. That's one hell of a tube. We need a co-op.

Hey rodger, I saw in another post that you had success with grocery store vegetable bags. The Oyster mushies looked great, by the way. Did it take special care, given the plastic's mil? Just wondering.

I was thinking not putting the straw in the pipe... get a 1-2" dia. pipe, drill holes up and down it, and put in the middle of the "log" so that when you're done with the flush you can pour water or hook a cool mist to it or something to re-hydrate it. Wouldn't that work? Might be able to get a couple more flushes anyway...
By rodger rabbit (Skyypilot) on Thursday, April 24, 2003 - 01:12 am: Edit -------------------------------------------------
Yes, gotta be careful stuffing it. If it were any bigger, it would need much thicker plastic. It was just something to try, and I gotta experiment with stuff. Oyster mushies rule! The o'lady's in the kitchen right now. Shes got them in a skillet with a white wine cream sauce. It smells so good, I'm drooling on the darn keyboard.

On another note, if it truly is 8" diameter, (not 8" lay flat width), that's a cheaper price than Graingers. Good find. I'd still recommend going with 10" though.

Uh, I already mentioned the hollow PVC pipe with holes and verm to let the water rehydrate the log from the inside, remember? Back when we were talking about how to hang it, I figured that you could hang it and have an inner reservoir to help you get more out of it.

By Mod PissyBee (Pissybee) on Thursday, April 17, 2003 - 05:21 pm: Edit

Yeah, instead of wood, use a hollow pvc pipe with holes throughout the length of the tube and pack it with vermiculite, pasteurized dung, or something that holds water, then you can rehydrate the log as much as needed. Any thoughts on that?

Anyone think that would work?
By Hippie3 (Admin) on Thursday, April 24, 2003 - 03:44 am: Edit -------------------------------------------------
a slightly different concept than what i was talking about in my post originally,
but an option in line with the rehydration theme.
i dunno tho', i'm still thinking dunking the entire log 'as is' is proly going to be easiest,
the pipe can hold the weight and still keep the log intact and moveable.
my experience has been, in general, that you get better results from a massive short rehydration like a dunk than with a steady drip feed. the steady addition of water into the core would, imo, tend to create anerobic conditions near the source, proly killing off the mycellia over time.
it's better, imo, to get it really wet then let it dry. in addition, a dunk would deposit the water more to the outer rim instead of the core. the outer rim is what dries fastest anyway and would seem to be where moisture is most needed, not near the core where evaporation is very slow.
By Mod PissyBee (Pissybee) on Thursday, April 24, 2003 - 03:51 am: Edit -------------------------------------------------
Okay, so how about a hollow PVC with holes to help hold it together, for transportation and for dunking? The holes would allow drainige from the center so it wouldn't get too water logged and then you could rehydrate the whole log at once. Or is that what you were sort of talking about? Nice to see ya back Hip, always nice to here a bit of your wisdom!
By Hippie3 (Admin) on Thursday, April 24, 2003 - 03:55 am: Edit -------------------------------------------------
yeppers, that's what i'm conceptualizing about.
i can see little 4 inch wide 2 feet long sections of straw-stuffed pvc like little sausages lined up on shelves. inch-wide holes bored every couple inches for fruitbodies, no real need to see inside anyway, just let it do it's thing until shrooms form at the holes.

I can see next weeks New York Times financial page. . .

"New York(AP/UPI) The price of straw futures have risen dramatically on the big board in recent days. It seems that every store in America has sold out its entire stock of straw to 'freaky looking' people for as yet undetermined uses. . ."

I like the chicken wire idea to hold the substrate together. Do you think nylons or fishnet leggings would work too for the smaller sized logs?

I was also thinking about using one of the plastic closets with metal frames you can buy at Wally World or the K as a humidity tent. You could hang the logs inside and line the bottom with wet perlite. Then check on it twice a day to air it out and give it a good misting.

Or you could rig a humidifier to it and cut holes in the bottom to allow for CO2 and O2 gas exchange.

the closet set-up is pretty sweet,
i had one.

Just keep it flooded with fresh air, to keep the contaminants from getting a foothold. Nothing is sterile with the logs, so you need lots of airlow. I was looking at a healthy piece of mycelium from a log the other day through the microscope. It had a dozen or so bacteria spores, and a few dozen mold spores, just waiting to germinate, all in an area of mycelium the size of a grain of rice. Scared the hell outta me.

Those of you that are still searching for the plastic tubing, there is this website that I found
Polyethylene tubing for growing mushrooms in straw or sawdust. 12" diameter, not perforated.
$13/20' $179/500'

LMAO @ Rogers post at the NY-Times finacial.....

i wonder if one could make a log work perhaps a bit better using string/twine. maybe nylon so it won't rot, like fishing line. a hand-made mesh of sorts to hold the straw together yet open up the surface.
tie it up all around, nice and tight, then cut off the baggie so it can breathe better. kinda like spacecowboy's idea.

rodger, what do you think of:

5. Scratching. Not related to moisture really, but damage from drying surfaces. Cakes which have drying damage can be encouraged to fruit more by thoroughly roughing up the surface with nails or forks. Scratching is also commonly practiced when growing oysters on uncased straw. As in number four, I'd combine this with dunking or some other rehydration method.

By Jesse James (Spacecowboy) on Friday, April 25, 2003 - 06:03 pm: Edit -------------------------------------------------
Once the logs are contained in some sort of scaffold to keep it together, you could get a 50 gallon drum to dunk it in.

Could you possible use the bleach tek to help keep the contamination in check, with some sort of nutrient mixed into the bleach tek water to help boost further flushes?

Some links for possible back up info:

I have seen the plastic metal frame closets with wheels, this would make the larger logs easier to move around and work with once hung up.

Hey Hippie3 have you ever heard of jute? I worked construction a few years ago and we had these rolls of "Jute" that we laid along the roadside ( jute is also called erosion (sp?) controll blanket)

Anyway it is a nylon "mesh"(probably 2 or 3 inch squares) with either wood or straw (depending on the brand) intwined.

It comes in great big rolls four or five feet long and about 2 or 3 feet around.

Basicly could this be used for anything ie Rodger Rabbits Straw Tek?

Even if not used as the substrate (straw) couldnt it be sterlized/pastureized and used as some kind of "wrap" kinda like your Fishing line idea?

It is pretty strong stuff and would hold up quite well I think. any input?

And by the way Welcome back we all missed you so very much even those you didnt know you knew like us newbs

How about using the pvc/soaker hose in the middle and that
orange plastic fence stuff that has 1X2 inch holes on the outside?
You know the stuff they use for portable crowd control
or around work/construction sites to keep folks from falling in?
Just a thought

Hey Rabbit, my log is 100% colonized. remember I used the 30" pool rings from walmart...anyways I started it last sunday and it is white all over now 5 days afterward. the rhizo growth is absolutely beautiful. the only thing that is a problem is that a few spots aren't colonized but these corrospond with the air slits so I'm not worried. I'm anxiously awaiting pins...the thickness of the plastic i'm using is wonderful I was hesitant to move it from what you said but the pool ring platic keeps everything very ridgid. Anyways how many pins should I wait for before bringing it out of the plastic? What if anything should I add to the misting water when I have it out? I'll post pics soon...I'm not blessed with my own camera so I'll get my buddy's

I can honestly say I've never found this vigorous growth following any other tek... I went from a few pint jars of innoculate to a straw log that's three feet and weight's tens of pounds. Thanks for your creation and generosity w/ info.
By rodger rabbit (Skyypilot) on Saturday, April 26, 2003 - 03:40 am: Edit -------------------------------------------------
let it have a few pins before birthing. It will take two weeks...I could almost set my watch, that on the 14th day there would be pins. after birthing, just keep it covered loosely with plastic that has lots of holes cut in it for ventilation. Don't mist. Misting is bad for the mycelium, and bleach is even worse. Glad it's working out for ya!

I wanted to say that I have really enjoyed this thread. Very nice work rodger, don't see much like this anymore.

Keep up the experiments, us elders are still floating around out here

You could make a stick or tube out of rolled up hardware cloth and use that as the log's backbone during the process of packing the tube.

That would help O2 flow as well as make it stronger.

Then, cheap bamboo skewers or heavy wire could be run through the log into the mesh "backbone" and out the other side at intervals down its length. It seems to me this would stabilize the entire log and allow it to be suspended vertically.

All my jars are in the dark and I'm bored so I took a 12" impulse sealer for mycobags and some 4 mil plastic sheeting from HD and in about five minutes made a six-foot tube. It seems like if you have a sealer you don't need to buy the poly tubing on a roll. And it's fun!
By d (Nilla) on Sunday, April 27, 2003 - 07:55 pm: Edit -------------------------------------------------
I have question how moist does the straw need to be and how much spawn per 12" tube?
By d (Nilla) on Sunday, April 27, 2003 - 08:14 pm: Edit -------------------------------------------------
I also baught some plastic from lowes its meant to be a throw when you paint,i cut it 24" wide and 3 feet long taped the cut together with clear box tape makes it 12"diameter seems to be a great substatute and still have enough left to make ten or more, for $3.
By rodger rabbit (Skyypilot) on Sunday, April 27, 2003 - 11:22 pm: Edit -------------------------------------------------
Nice job guys! Keep thinking! The right moisture content for straw is obtained after pasteurization by letting the straw drain on a screen until cool. Whatever moisture that drips off naturaly will leave the straw perfect for spawning. A good rule of thumb for the amount of spawn to use is 10% spawn, to 90% straw. Then just pack the log until you use up all the material.

I found a good way to hang the log vertically if anyone needs to do it. Just hang it from the plastic knot on one end. Let the other end rest on a table to hold some of the weight. When pins form, don't birth the log. Just cut slits with a sharp knife down the length of the log, about 1" apart. The plastic will still hold the log, but the fruits can push out the slits.
By nilla (Nilla) on Sunday, April 27, 2003 - 11:49 pm: Edit -------------------------------------------------
as far as pasturizing goes can i do it in a oven set at 170 and also ive read somwhere it said if you exceed 160-170 your setting up for failure as it will explode with micro orgainizims . so you cant go above 170?
By rodger rabbit (Skyypilot) on Monday, April 28, 2003 - 01:22 am: Edit -------------------------------------------------
Actually, you want the mico-organisms to survive. It's the bacteria and fungi contams(trich, etc.) that you want to kill. The heat and lime takes care of that. I try not to go over 160. I've never done it in an oven, but part of the pasteurization tek for the log is that it also hydrates the dry straw. Just get a rubbermaid or plastic trash can, and heat water on the stove per the tek. It works. I've heard of guys soaking the straw, then loading it into one of those oven roasting bags they make for turkeys. I think there's a tek for that, either here or at the shroomery.
By Mushroom Zen (Sno) on Monday, April 28, 2003 - 07:32 pm: Edit -------------------------------------------------
I always use 170* and have never had a problem... should I bump down to 160*? Could I just load straw into big turkey pans and put hot tap water in, cover with foil, and bake at 160* for an hour or so? Think that would work?
By Hippie3 (Admin) on Tuesday, April 29, 2003 - 12:47 am: Edit -------------------------------------------------
proly, shoot for about 165 and you'll be ok.
By indicaz (Indicaz) on Thursday, May 01, 2003 - 01:11 am: Edit -------------------------------------------------

ok where is the tek?

or am i just blind and not seeing it?

This is amazing.........
