Ok I should have posted this a long time ago here
but unfortunately at the time I was very very busy
and was having enough trouble posting it at the shroomery.
I got so fed up with uploading 3 pics a day that I stopped replying to half the thread.

Now that this board is so user friendly
its a more appropriate time to post this with updates.
This method works wonders for me.
There is a ton of debate wether it has fae or not.
But all I know is it works for me. Try it if you like, but please get this tek down before you dis it.

I have changed my ratios and updated it from double tubs to single tubs now.
So most of this post is going to be the old post. Followed by the new updated post.
I have some down time so I can actually sit here and do the entire thing in one sitting.

Eat Yu's How To

First of all I want to say that this tek is derived from many other teks.
It is just my little twist on it.
This is simply put, Millet's Tek
with Eat's adaptivity to it.
It doesn't mean it is better or worse,
it is just a little different with ratios and utensils!
Millet suggested I try these dub tubs and I have found they work wonders.
I have since changed to single tubs with the same effect.
Different ratios and methods but very similar just upgraded. This will follow.
Jethro from the nook and Ohmatic from shroomery also helped me
adapt this tek into what it is now.
also [user]doesntmatter[/user] suggested trying this press n seal wrap from glad
and its working great.

The basis ratio for this tek is basically 50/50 dung/verm.
The casing is also 50/50 coir/verm.
you can use peat moss
but one 1/4-pound coir brick equals the entire casing for one 64 quart bin.

Recipe for four 64 quart clear bins for double tubs.
Ratios Per Turkey Tins( 4 turkey tins total):
12 cups screened worm castings
12 cups vermiculite.
1 quart distilled water
1 quarter pressure cooker bag full of straw per 4 turkey tins

so your total for 4 turkey tins would be
48 cups dung, 48 cups verm and 1 gallon distilled water.
we will mix these ratios later but for now we will just tell you these ratios.

supplies needed:
2 long sterilized spoons ( long enough to break up mycelia in quart spawn jars)
4 turkey tins
dry worm castings
plastic gloves (powder-free)
painting mask
ozium or disinfectant spray
rubbing alcohol
finely chopped straw (preferrably chopped with a food processor or wood chipper)
thick aluminun/tin foil
terrarium lid for filtering (available at any pet store)
5 quarts of colonized spawn
extra distilled water
2 large glass jars made for pc'ing, gallon size preferably
(these are available at any asian market that sells kim chee- which is a korean cabbage dish)
the lids also come autoclaveable!
These large jars will be used to make the 50/50 casing soil


All pre steps done the night before
Pre Step-Screen your worm dung with a terrarium lid for a reptile aquarium
Pre Step-2 Finely chop your straw until it is almost 1" to powder size. the smaller the better.
Pre Step 3- soak straw 24 hours, strain then pc for two hours.
Explanation: the finer the straw is the better it mixes into the spawn run. also, the spawn run is much shorter when the mix is more even. now presoak this straw for 24 hours. Then pc the straw for 2 hours at 15 psi. Remember though you don't have to do this straw step until the night before you decide you want to do the spawning. Also, it isn't advisable to keep straw sitting too long even after it has been pced bc straw is very quick to contam. I would suggest keeping it in the pc until you decide it is time to spawn or it would be better to just pc it the night before you spawn.
I often tend to do this in a few steps which make it a little easier. I cook everything the night before and then spawn everything the next day. Just make sure you have a clean working area. Everything can be done open air. It is advisable to run air filters and spray disinfectant spray in the air before you spawn. It is even a good idea to drop the house temp about 5 degrees a few hours before you do the spawning. Then turn the ac off while you do this spawning.
Below is a picture of the texture the straw should be. this has been chopped with a food processor from wallmart. After that picture is a picture of the straw after it is soaked and pced.

Here is another picture of the straw pre soaking. notice in the picture that the larger pieces of straw are right next to the finer pieces. this is for comparison. you do not want anything over 1" pieces. in fact powder straw is even better! this will be pointed out when we get to the spawning section!

1. Add 16 cups screened dung and 16 cups vermiculite to each turkey tin. We do 4 turkey tins with this same ratio in each.
2. You also need your gallon of distilled water for this step.
Posted Image
As you can see the vermiculite and dung are piled in the turkey tin. I have adapted this technique now to mixing everything in one big mixing box. this is then transferred to the turkey tins. this will be shown later.
Posted Image
....straw amount after being soaked and pced! This is about the amount of straw you need. I would say this is about 1/2 a turkey tin full once it is laid out. There is no ratio just fill a large bowl and soak the straw. then when you pc it try and get about the amount in the picture below. The key to this tek is speedy colonization. Straw contams hella fast so you want the straw to colonize asap. The other principle of this is that you want the dung to soak up the extra water from the straw. If you have overly wet straw you will have microbes growing up the wazoo! I purposely make my mix in the dung/straw a little dry to soak up this extra straw water. Now take note that if you think this ratio seems a little too dry, wait till it is pastuerized. It is definitely the right ratio!

3.Add 1 quart distilled water or 1/4th gallon per turkey tin( I now use tap water). you want to mix this using gloves and make it light and fluffy and very soft. it will be pea size particals. just like your pf mix! but just add a little at a time. you may add a little more water than a quart but a quart works perfectly!
4. Ok now one of the keys to this entire tek is this mix. You have to make sure this mix is so light and fluffy it wants to float out of your hands. You can use the drop squeeze between the finger method to make the moisture correct. But this mix actually speeds the colonization.

....Look yummy all nice and shitty. the shittier it looks the better! .......Had to add the shit humor!
This is what the mix should look like after you are done mixing by hand! Nice and fluffy!
Posted Image
This just explains a little more about moisture content. The flushes with this tek are incredible and don't need more than the correct moisture content. The condensation that is created in these chambers is so high that it renourishes the water back into the substrate for post 1st flushes.
6. Now place the thick large tin foil over the tray so that it is air tight. Make sure the type of foil you use is very wide so that it fits directly over the turkey tin and keeps all the moisture in.
7. Now you have to pastuerize the dung/verm mix in the oven. Preheat your oven to 185 degrees.
8. Place the trays in your oven and cook them for 2-4 hours at 185. The temp may vary dpending on your oven but for the most part you want the inner temp of the mix to be about 160-170 for a steady two hours. I always cook them for 4 hours but friends have had success with 2.
9. You can time this where you can start pcing the straw now. It will take two hours so cooking time is perfect.
10. After the 4 turkey tins are done cooking leave them in the oven to cool overnight.
Here is a picture perfect example of the best shitty mix on earth. Please feel free to copy this picture to your desktop and print it for framing on your wall at home!

This is a snake cage lid for an aquarium. You can get these at any pet store. This is used to screen the dung. Also look in the archives for this. From FM.

11. Now you must prep everything for spawning. I usually run an air filter and spray disinfectant or ozium in the air. you need a mask, gloves, pced spoon, 5 quarts of spawn and an extra tub for a mixing box.
12. Clean your work area and prep all materials.
13. I use rubbing alcohol to clean each bin inside by hand. Then stuff the holes with fresh polyfil. Make sure you clean the top of the lid also because from here on out each lid stays on until the spawn is transferred from the mixing box into each chamber. Once the transfer is complete you don't open the bins again until it is time to case. The polyfil allows enough fresh air and co2 buildup for the perfect spawn run. The spawn run has always been no more than 4 days with this tek. If this doesn't happen you must have contamed something. It will probably smell sour- but that is a different lesson- lets concentrate on the tek for now!
14. Now I use 30 gallon black plastic trashbags and open the bags halfway. I then place them on the bottom of the chamber where the sides creep up the sides of the chamber.
once you place the plastic bag in the tub, put the sterile lid on top
Posted Image
15. PAY CLOSE ATTENTION: Spawning must be done very quickly this is open air. And you must not breathe on it so wear a mask. The straw is also very vulnerable to contamination so we must use a lid on the mixing box.
16. Use another trash bag lined in a 64 quart bin for a mixing box. Make sure you rub the bin and lid down with alcholol before use. Then close the lid!
17. Here it is in a nutshell, Basically dump all 4 turkey tins very quickly in the mixing box and then add the straw.
18. Begin mixing the mix with your glove covered hands.
Posted Image
Here the straw and dung are dumped into the mixing box!
The mix is then mixed by hand consistenly until it is almost the same texture as the previous mix. You want this light and fluffy feel to it everytime. Works like a charm!
19. It is easier to do this with two people, however you can do it alone. just make sure everytime you are done mixing close the lid. Keep as little air exposure as possible to prevent contamination.
Posted Image
20. Now you have to break up your 5 quart spawn jars and dump them right on top of this mix!
21. Now after that break up any seed that is stuck together by hand. Make sure each piece of wbs is broken up so that the spawn mixes better. You then make a twisting and turning moition and make sure you get the bottom of the mix. Try and mix it to where the spawn looks evenly mixed throughout the entire dung/straw.
Posted Image
22. Look closely and you can see the little white dots in the mix. This mix is almost done. It looks very even and consistent
.....Another view of the mix
Posted Image
.....Another.. I stress these pictures because they are very important!
This is the final product and the mix is done!
Posted Image
Finally Transfer handfulls of the mix into each separate chamber( 4 in all). The sub level should lineup just about an inch under where the polyfil holes are. The depth is about 4 inches. Spread the mix evenly and smoothely around the bottom of the chamber as if you were going to make a casing.
Let this incubate somewhere dark for 4-5 days. Then when it is fluffy whie it is time to case.
Casing: Casing is prepared excatly like the 50/50 dung/verm mix except the dung is substituted with coir! Then it is pced for 1 hour. This casing is the exact moisture content of all the mixes in this tek. Once you get this ratio down. It is a breeze because it is basically doing the same repetitiveness.
This is what the colonized sub bed will look like
The problem many people have is the part where the casing comes in. Now tek stresses the fine ground straw because it mixes in perfectly and doesn't leave any big pieces of uncolonized straw to get contamed. So the substrate should look like this in a few days. The best part of the clear bins is that they allow you to see when the bed is colonized before you give it air exposure.
Incubation can be helped by placing a dark black plastic sheet over the bins or a sleeping bag
....once the spawn has been colonized case it and incubate it for about 5 more days. sometimes the casing will colonize in 3 days but 5 is ideal!
After the casing has colonized, it will look like this on the outside of the chamber. Notice all that condensation. It may look like too much but it isn't. This plays a key role in the later flushes. It actually has enough moisture for a few flushes without rehydrating between flushes!
.....Now once the casing is colonozed just place the other sterile bin on top and let it sit in the light for about a week and you will begin to see pins!
And walla, the final product. Also take note that this chamber has only been opened two times. Once to add casing. And once to pick the fruits. The top chamber is then replaced after picking. If the casing is torn up patch small spots but don't add any extra water you will fuck the environment!
Notice the sides of the chamber. This condensation is created. It will build up and lower at the appropriate times of pinning, fruiting, and harvesting, then repinning. It is almost too perfect. YOu don't have to do shit for all you lazy mofo's out there! Go sit on the couch and rip the bong, bong rippas!
....This entire process probably takes close to one month but it lasts at least2 months of fruiting if you play your cards right. The average yield for these chambers is about 8-10 oz dry. But it has been reported to have 1lb flushes dry! from each tub. So next time your friend says they know all this shit and try and run you into the ground, you know you didn't do nearly as much work! lol
mature canopy!
....see the suns rays. it isn't advisable to have direct sunlight on the chamber. this may raise the temps in the chamber. use dim light but this is a nice little shot of the morning sun on the crop!
....You can see in this picture how fluffy and white the casing is below the mushrooms. look at the bottom left! This is what the ideal casing looks like!
z strain. oh yeah and just cause im a pro don't mean you can't do this! The above pics are my first try at this tek and this is how I did it.
I hope you have enjoyed Eat U's How To!
Ya' ll come back now ya hear!
Now, the mix isn't really the thing that matters much. as long as you can mix a bulk substrate, you can use any mix or method you want. its more to do with not fanning and being lazy. mushroom mark at shroomery was gettin 10zip flushes off one dub tub per flush using horsepoo. I definitely recommend horsepoo it the best. but regardless of what subs you use, this method works.
The idea is to create a self regulating environment that has little introduced after birthing. once harvest happens you then do in between flush maintenance such as reapply casing layers or dunk and flood substrates.
Here are a few pics in action below. This first one is the condensation prdoced using this method. you can actually see circulation patterns in the condensation on the sides of the chamber.

a mini dub tub. the chambers are iris 64 liter bins that i use available at office depot. they have smaller 44 quarts now but the lip is the key. this holds the other chamber on top with a nice snug fit.
Posted Image
this shows 4 stacked high. yes the tyvek works well. i just like polyfil bc i always like starting with new fresh material in case contamination got on the tvyek on the inside of the chamber.
Posted Image
hole placement is debatable and the number of holes is debatable. when i first tried this method, here is the only picture i had to go by. thanks to thanks guys for such a great idea.
Posted Image
the one thing is this. i can't stand fanning more than anything. i have tried automated setups and giant room size setups. to this day, i still find the simplicity and efficiency of this method overwhelming enough to convince me to use it over any other method. there are things on automated setups that irk me and cause more work. regulation and such. and these methods are so easy. i can douse everything down heavily with rubbing alcohol and have almost a clean bin right after the bin was contamed. everything is thoroughly cleaned.
casing layer-take notes here. i have updated this part big time. this is how i used to do casing layers.
Ok Here is the casing. Get a brick of coir and let it soak with a gallon or more of distilled water in a large bowl! After the brick absorbs the water it should look like this! Then throw about the same amount of verm as there is coir in the bowl and begin mixing!
Ok Here is the casing. Get a brick of coir and let it soak with a gallon or more of distilled water in a large bowl! After the brick absorbs the water it should look like this! Then throw about the same amount of verm as there is coir in the bowl and begin mixing!
Mix this casing just as you did the dung/straw. Light and fluffy! It will look something like this. This should be enough for the 4-64 quart bins. If not, mix more and just keep some extra in a pced container. The casing is then pced at 15 psi for one hour! Let the casing cool to room temp or even apply it the next day. After that lay it out evenly and flat over the substrate. Dont pack it down. Let it be nice and airy! After about 3-5 more days you should see your casing colonized. Do not open the chamber to look. Just look through the clear lid. That is what is so good about this tek. The air exposure is very minimal because of these snap on lids that come with these clear chambers!

ok now for the update. i have since reverted back to an incorporation of flatcake methods mixed with bulk substrate methods. i stopped using casing due to laziness of making them. instead, the casing is incorporated into the substrate by adding this 50/50 verm/ coir into the sub.
my new ratios are this by volume:
1)50/50 coir to substrate. then 10% of that volume is straw.
if your using strawnet(or eco straw litter or pelletized straw or wood or stove pellets, hemp pet bedding, ect..) as your 50% substrate, then i mix 10% dung to coat the straw. you can up this ratio to 15% if you want. either way it doesn't really matter. its the system of fruiting that i am more concerned with now. you can make whatever ratios you want.
im completely with jethro on this one. i agree 100% that the coir in the substrate makes the casing layer obsolete. i get as meaty and large fruits and yield off of this substrate without a casing layer as i do with a casing layer. i have been experimenting with tons of stuff over the last few years and im trying to get everything on this thread to update it. this is going to be for the nook only. i am way to lazy to change it at other places.
2)where the magic is to me, is in the mix. the big mixing box is where all the love is at. subs like straw and strawnet are boiled. or the eco straw litter is pre processed and then just added to the coir. i find that with the amount of water required to expand that coir the extra substrate and just a bit more additional water is needed to be added. but if your coir is extra wet then the substrate(verm, dung) will soak up this excess water. i find that using things like this in subs: (coir, dung) soaks up the excess water that lets say: straw, strawnet and other wet subs have. then after that i judge the moisture content. always make sure not to add too much and always work my way up to moisture capacity. after that i have found mc, i then add just a bit more moisture to allow room for evaporation due to the oven. this is all done by hand with gloves on. when it feels perfect. i put it in the tins. at times what i do is add just enough buffer agent like dry dung to the mix to soak up that extra moisture to field capacity. so i almost use the dung now as a moisture indicator. it sets me on the right track. that ratio consistenly seems to be 10-15% for me. i dont' use this dung as a nutrient additive although it does serve that purpose. i use it to regulate my moisture content and soak up extra moisture that may cause problems down the line.
at the end of this post is a few attached images. this grey box is the sterilite box that i use for mixing the substrate. this box 3/4 full should fill 4 turkey tins of substrate. here is another key to this. everything i mix now is by volume and eye. i don't measure out anything. i judge 50/50 volume by eying it in. so everything is not to the t. the good thing about this mixing box is that if you have too much volume of substrate, you can pack it down tightly when you pastuerize it. it doesn't matter if you sub bed is a bit higher in the chamber. you can pack it down just bit to make the sub level where you want it. you have room to play here. this is why i don't put exact ratios on this. originally in this thread i put exact ratios to give everyone an idea of what was going on. now its really up to you. once you find that point where the mc is correct and everything works for you. then, you will get it down to a t, you don't have to follow this word for word. it works well with any mix. i often vary the mix to try and see what works best. don't get me wrong hpoo is by far my favorite dung additive. but sometimes your shot for time, money and all kinds of other factors. so using worm poo or cheap black composted cow dung doesn't hurt. this stuff is 3-5$ for a 40lb bag of it. if you use strawnet or other substrate additives like verm/coir, adding 10% of this dung seems to work very well.
i used to use heavier dung ratios and heavier straw ratios. i get much larger yield with a heavy straw ratio but i find at times its difficult to deal with. i can't stand chopping and shredding straw and personally i don't have the space or utensils or even the space to store the equipment to shred the straw. so my alternative is to use substrates like strawnet and already chopped straw like pellets. so essentially you may look at this like a larger straw ratio being a 50% straw to 50% coir substrate. all the ratios i have used in experimentation have worked well. i do find, that only using vermiculite as the sub additive is about 1/4 the yield as using coir. no matter what you do, coir is always going to absorb more moisture than the vermiculite. i prefer coarse ground verm but any type should work. the mix is much better with the larger verm but work with what you have.
3) i use a giant mixing box and for the most part fill it 3/4 full. this will fill 4 turkey tins worth of substrate packed down tightly. then foil is placed over this on the turkey tin.
4)i cook in 4 turkey tins at 200 degrees for 4 hours. each tin fills one 60 iris liter bin. 2-3" depending on how tightly you pack the turkey tin.
5)let this cool overnight or time it to where you give it a good 4 hours to cool.
6) open air spawning is done using a clean area and some trash bags like the previous method. the utensils are all pced. a shower is taken beforehand. all air flow turned off. ac is brought down low for an hour before. the turned off. no airflow in the room. the spawning is done quickly. all polyfil and trash bags setup before hand in all bins. each bin is thoroughly rubbed down with alc. it is then sprayed with disinfectant spray and closed to sit for around 30 mins. everything is setup in the clean work area: black trash bags, polyfil, plastic gloves, pced spoon covered in foil, painters mask, disinfectant spray, alc, paper towels, ozium.
a) the bin is opened quickly. turkey tin dumped in. opened one more time grain spawn spooned in. this is all done in a row. 4 bins take up quite a bit of table space. so each process is done in a row.
B ) the key to this is to make exposure to air minimal. keep everything inside the bin. next is to get the spoon out and hold two wbs quarts of colonized spawn per one turkey tin in each 60 liter iris bin. you take both lids off and break up spawn and throw it all in the bin on top of the substrate mix.
c) make this quick. them move on to the next tub. 8 quarts per 4 tubs. 2 quarts each tub. after that and all lids are on.
d) now put gloves on and break up all spawn. mix all spawn nice and even throughout. make it light and fluffy and don't pack it down. this is a very light substrate
e) put lid on and allow to incubate for about 5-7 days. you can see through the bin to tell when the sub is 100% colonized.
7) after that colonizes it is birthed. i am now using single tubs with polyfil holes in the sides along with saran wrap lids. with no holes or anything. 4 pieces of tape and that is all.
8) At birth, this is what i do after that.

Recently, i have figured out a few things with these saran wrap lids. its with the bins that i use, but it may be useful with the beer boxes. Someone told me about press n seal stretch wrap similar to saran wrap but sticks to any surface. i will try this out soon. however, i think i may be onto something here.
when i do these beer boxes. i get mass condensation buildup where i see it pooling on the substrate. however, i didn't have the space to tilt all the boxes i was runnin at the time. now i know my setup is a bit different than jethros box tek. i actually use the black plastic bags to allow the condensation to fall to the sides of the substrate so this is a bit different. but i thought this might be a good thing to add to this as well. i use both of these methods. and i like both of them. i find it a bit of a pain to punch holes in boxes. so i have a bit sturdier plastic iris bins that i use. these were already available so everything was adjusted with what was available. with a really helpful hint from jethro i used saran wrap on the lids. they are usually 12$ now. this one might be much larger than the one i use.
iris clear stack
i find when pins start to develop, if you wait one day when the condensation builds up, that you won't have to open the saran wrap at all in the bins that i use, if you tilt the bins. so that is usually the time when i have to open the corners a bit
to allow some of the condensation to escape so that i don't get contams. generally if i get contams its at this point. where the moisture is too high and it gets all over the top of my substrate.
with the polyfil holes and the 45 degree tilting, im just wondering if it creates a vaccum that sucks in air through the polyfil holes. it seems to work like charm where i don't have to open the boxes at all. or the saran wrap. now i don't open them until harvest.
at first with jethros tek, i had trouble with water building up on the substrate surface. i would sometimes soak it up with paper towels. but i had a few bins contam because i wasn't around to tilt them or didn't have the space. essentially when i tilt my boxes now, it redistributes the moisture in the bin and some of the droplets go underneath the black plastic. so the underside of the substrate isn't really being touched.
so i used to tilt to not allow moisture on the casing or sub layer.
now im tilting to not allow moisture buildup on the top of the saran wrap. this prevents the moisture buildup on the casing when i catch it at this stage.
if you catch the moisture at this point and redirect it
it works like a charm
so i find that i don't have to tilt the boxes the entire time. i just eye it now. i simply see moisture building up on top, i tilt it, if it looks fine, i place it back at a normal angle. this gives me most of the mushrooms pointing str8 up.
here is something that may help. im finding out about flooding and dunking. it isn't necessarily going to work all the time. what you should know is this. make sure the substrate is 100% colonized if you dunk. i have heard stories of subs contaming bc of uncolonized underneath beds. try and leave the mix even as possible. this allows those spawn grain to reach all spots. if your sub is taking longer than 7 days to colonize you should worry.
sorry about the scatterbrained text, hopefully a mod will keep this open for me to edit bc im going to change everything on this one post so its only one post.
i don't advise against keeping your boxes tilted the entire time. it makes no difference to me. if it works for you keep it up. i just don't have space. my situation is a bit different that is all. max boxes that can be tilted is 2. most of the rotation is 2 box rotation a week. so it works out.
at this moment im using tazmanian strain. my problem is im limited for space. so i can't tilt all the boxes at the same time or there won't be enough room. but i have just been observing the times when most of the moisture content has been building up. this allows me to selectively tilt my boxes. i catch the condensation right before it builds up and it actually only takes a few hours of the box being tilted for it to do what i need it to do. also, the boxes i use are large boxes. so tilting 8 of these would take up half of the room. rather, i can tilt two boxes at a time while the others are pinning and such and so on.
below is a picture of a sub bed that has been taken 4 hours after a good tilt. all the moisture has been redistributed in the chamber. the sub may look extra moist with water condensation but its actually at the perfect state right now and this bin is going to fruit like a mofo
the forum just cut me off. i was in the middle of editing but it changed.
flooding or submerging additons
1) casing layer- I treat the two differently. With casing layers, I don’t ever penetrate the casing level. I try and only flood the casing layer itself and with casings I do this at an hour at most. With cakes, the entire cake soaks up all the water. The substrate is a bit sturdier and in most cases you don’t want to damage the casing layer. With the substrate and no casing layer, you have more harsh treatment you can dish out. If anything I will generally slightly flood the casing or use a spray bottle to re-mist it. At the most the casing is flooded an hour. You have to be a bit careful and not tear through the casing layer. I generally don’t use a spray on the casing layer because I don’t want to damage the network of mycelia. With the substrate, it can take a nice hearty beating!
2) no casing layer- I treat the substrate like a big flatcake. I submerge the entire cake after 3rd flush. Generally, the substrate starts pulling away from the sides of the bin after 3rd flush. So what you can do is use the black plastic bag and position it so that you only flood the pinning level of the substrate. After 3rd flush you generally are going to be dunking the entire substrate. But after a while if you leave pooling water underneath this sub bed it will contaminate. Make sure you pour out all excess water during the dunk or else you will have problems. You can actually tilt your box at a 90degree angle and use the black plastic to hold the substrate in the tub. This will get out all the extra water.
The sink spray nozzle seems to have enough force to clear most dead pins, and make room for the newer smaller pins. Once they get re-hydrated, the pins begin to mature. I don’t believe that new pins are actually forming when this happens. I think the smaller pins were formed at the initial pin set and they are just being re-hydrated back into animation.
I never really flooded a substrate until i witnessed it in nature. i found this field that would flood when it rained. at least 2' over the level where the cow patties were. this was a swamp floodplain area. it would get very dense with water. after a few days and all the water cleared up. the cowpies would explode. the patties were located underneath a grove of swamp trees and the flooding would make them explode. i mean these things would be covered day after day, harvest after harvest. so i decided to try out flooding the cakes. i had dunked flatcakes before between flushes but never really wanted to try it on sub beds. i was afraid the leachate and gunk in the subs would contam. once i changed my ratios the mix started to seem to be more the consistency of a sponge. the substrate actually seems to work like that. i was trying to go out ot that field and then i found myself knee deep in water halfway through the field. it was funny. but ever since then, i started flooding my substrates.
i just noticed but it appears that iris isnt making these larger bins anymore. they have the smaller 44 quart bins. the ones i have are either 60 liters or 60 quarts. i am not sure which. my tag that is on my bins say iris clear stack 64 liter storage bins.
iris smaller 44 quart bins
all of this info is updated from double tubs to single tubs. many of the techniques are the same as the pictorial. however, a few slight modifications have been done that seem to suit the methods better.
gallery of pictures using both of these two methods. dub tubs and single tubs.

press n seal lids now instead of saran wrap. this is being tested now. i may have to regulate rh more because the saran wrap is a bit looser. this stuff really makes a tight seal.

and there is tons more below.
this shows a picture of where the polyfil holes are relevant to the casing layer. usually i use 1" diamter holes. i have heard ideas such as poking smaller holes underneath the substrate and such. there are so many things you can do. its all about finding what works for you.
sorry if these pics are too large. i am not sure how to format them on this board.

is there any reason you switched from the double bin method?
good question. well previously i had tons of space both vertically and horizontally so i had no limit. now i have a very confined space so if i can utilize two tubs and get similar flush then so be it. i tested methods using lids, with automation, without lids using saran wrap, anything you can think of.
i was having problems with contamination and no air flow in my bins with saran wrap and the holes in the bins until i started opening the corners and tilting the boxes. tilting is still a bit space consuming as well so i had to stack the boxes criss cross on eachother. at the time i was doing those dub tubs i was very busy so i didn't really have time to reply to anything. i need to post that thread over here. its just going to be difficult. it was difficult getting it at shroomery . i had to upload 3 pics a night. took like a freakin week. their board wasn't as user friendly as this board is now. i used to actually have a more difficult time posting over here than shroomery . but now everything is running very smoothly and quite user friendly. i thank whoever had responsibility for that...
everyone used to tell me why not use single tubs? my only problem at the time was that i couldn't do them without fanning. there were times when i would be away from bins for two days. i can't fan that. it will contam if i don't fan in two days. ohmatic over at shroomery pointed out that you can use the lids and have good results. so i tried it. and started experimenting. i went through a good 6 month contam, feeling out process. nothing seemed to work until jethro suggested using saran wrap...thanks jethro. ever since then, i have just adapted it to my dub tubs and everything is working out better than ever before. now the yield (in my tests)i was a bit lower using a single tub. but if you think about it this way, you now have two tubs so double the yield which is just about equivelant of one dub tub flush . and now i can stack these bins 8 high if need be. so it works out well. i spend very little time maintaining things. the time i put in is making things right before i put them in the fruiting chamber.
by the way, i used to use close to 30 of these 64 liter iris clear stacks. now im down to like 8 with similar results. not same yield of course because it is about half of what i used to do. but now space efficiency is much tighter. yield per square foot is quite pleasing.
also fanning that many bins daily is a fuckin fulltime job. this is the main reason i didn't use single tubs. now that i can do the same thing without fanning, then i switched.
the yield is very similar with or without casing. i am sure if you double your substrate you will double the yield. you just have to be aware that the condensation is going to be much higher and you may need to regulate rh more by opening the corners and such.
here is a log by mushroom mark at shroomery. he experimented quite a bit and made magic happen. he was asking me quite a few questions when i first posted this post and now he did very well. believe it or not, that guy was just getting into the hobby and look what he did. wow!
