After you case your bulk sub and put it in your greenhouse to start pinning/fruiting, do you mist it still even if your maintaining 80% humidity (humidity maintained by ultrasonic) in your greenhouse? Steady temps of 75-76 degrees, good fae from the cool mist....

Just seems to be taking long for this batch.....

Its 3 pints of wbs spawned to 3 pints of straw/composted cpoo, fully colonized in a 2.5 gallon zip lock into a log shape sorta, cased with coir. Introduced light to it one week before i cased (after full colonization of sub) and dropped temps to fruiting (75-76) in my closet. after the week was over, i added the casing layer and put it into the greenhouse to start its pinning/fruiting cycle. Still no signs of myc trying to attach itself to the casing layer or signs of knots/pins after a week.

Yep , u still need to mist exposed casings, as they will gradually lose moisture with an 80%RH...That may or may not be the reason for slow growth..It's pretty easy to tell when coir is drying out by the color change..If it's moist then there may be some other reason..

i just misted today for the first time, it was medium brown looking, instead of dark brown. i will continue to do so. after i get pins, do i want to continue misting? or wait till first flush is done to resume misting?

is there any good videos or threads reguarding standardized proper procedures on running a gh? I have the video from youtube (800 megs) of mushy cultivation about pf cakes and rye berries and agar multispore. But they just use little terrariums like tubs and 10 gallon fish tanks. Havent seen anything like the sort for gh growing. Would love any info on this to help me stay ahead in the knowledge department :)

you should be able bump up humidity if you stick another humidifier in there. 80 is pushing it imo. I get 95% with two cool-mists in a 6x7 room. hardly ever have to spray'em down, plus they dont get dried out mid-fruit.

Good luck:pirate:

this is casings, not cakes. it was my understanding that casings like 80% humidity, whereas the cakes need 99-100% . is this wrong?

[golly]

80% is ok for casings but u will need to continue misting, especially if the air is moving.
It can be beneficial to gradually expose the trays to more fresh air as they move toward fruiting..If your new casings are initially covered with foil, then a gradual loosening of the cover helps to conserve moisture as the sub matures..
It's either that or more frequent misting when the RH is on the low side..
80% is slightly low but doable..
It is of great importance to have the optimum moisture content in a sub as pinning time nears..Hopefully yours have not dried down too much..

An ultrasonic should easily get a greenhouse up to 100%. I keep mine at around 90-95% rh depending on what i'm growing and the temperature i'm growing at. I like to use 90% rh for 65 degrees and below, 95% for anything higher than 65 degrees. Cased substrates will dry up on you with warmer temps and low rh's as mentioned. So try to keep the rh at 95% for subtropical/tropical species.

[Lazlo]

Got any pictures of your greenhouse man?

[greenweanie]

here you go lazlo.....
cubies is what i am growing by the way, gc strain on wbs spawned to poo/straw with coir casing layer.

thats a lot things going on for such a small amount of substrate, GW. I bet you'd get better results with that amount of substrate in a single easy to manage tub. unless you plan on doing more than that in the future. it's kinda like building a gymnasium to play a game of checkers in. hehe. my advice would be to downsize with those trays... can you air them out everyday? or is that the problem?

room to grow, so to speak

[Mermaidia]

When you see pins, don't mist them directly. You can still mist around them. But misting them directly can cause them to abort.

[fahtster]

well.. theres a reason that the invitro, chronic teks, sandbags, salad bowl, bins crammed with cakes etc. work so well.. the fruiting environment suits the substrate.. if you are going to have only that much substrate in a fruiting environment that is much bigger, you should at least consolidate the immediate environment by wrapping the shelf that the subs are sitting on in clear syran wrap. this will keep the air from falling thru and you'll maintain a better atmosphere directly around your substrate as the air more "seeps" down the sides than quickly falling. but, I've been there a few times and right now you're creating an environment for something that doesn't exist. lol more work for less pay off as it's f'ing with your current crop.

1 week isn't that long being you didn't put the project back into incubation mode after casing it.

You've got some greenhouse issues you need to work out. All of the inputs should've been piped in at the bottom of the greenhouse to be honest. Don't feel bad, I did the exact same thing sort of. Not through the roof, but the last tier wall. IMHO i'd get rid of the coolmist you're using for FAE and would go to a straight up fan that's mounted in a box. Put it on a timer to come on once and hour for 15 minutes. Timers are cheap. One thing about piping the humidifier through the roof is, all of the moisture that's being piped in falls straight down. You'll also need to get yourself a small fan that can take a bit of moisture, put that on the shelf of the first tier. Screw this. Do you want to see a photo of the one I have that's the same size as yours?

Something else, can you afford a $110 humidistat?

[greenweanie]

thanks for the advice, and yes, hippie is right about the room to expand, i have 12 more pans to place in the fc as soon as they are fully colonized and cased. 6 of them are about 95% as of yesterday, another 2 are about 75%, and the other 4 are about 10%. 1 of the 6 (smallest bag-1 pint of wbs, 1 pint of verm/coir) is a test since the wbs almost looked like it was developing a green spot. 1 of the 10% ones is looking like a couple seeds are getting green spots. i spawned some to verm/coir mix, some to poo/straw mix, and some to verm. I marked the ones that were pc'd substrate so i would know if i was getting the nasties from untreated sub or not. I did the mixing in 2.5 gallon zip locks, and letting them colonize in there since i dont have as many contam issues inside the ziplocks :) I figure once they are colonized, it should fight off contams alot better, then i will be casing them. the bags are sitting in their respected pans to help form them to their new home, however they seem to end up lumping up like logs, lol. heres a couple pics of stuff about ready.........

Give me a little bit. I'll go run down there to take a picture for you soon as possible. It's a cool greenhouse that took several times of switching this and that, arranging this and that and I finally nailed it to work perfectly for every species I intend to grow in it. Trust me, a greenhouse can be a piece of shit if everything isn't on point for the most part. You'll find this out once you start to grow species that can be a bit tricky. So you may as well get her right, right off the bat.

[greenweanie]

thanks lazlo, will keep an eye out for it. the more help the better. i am after successful grows, so whatever it takes to get me there. the gh was the best way for me to do multiple small pans instead of throwing all my eggs in one basket, so i can keep contams out of my grows.

[Lazlo]

IMO you need to purchase a humidistat. Greenaire's THC-1 is a good one for the price. Just don't put trust into the dial's setting. You'll need to set the dial to the point where moisture starts to build up on the shelves of the greenhouse, then turn it back until it shuts off. It's a $110 at a place I can point you to if you want to purchase one. Buy it!

Here's the greenhouse that's the same as your's that I have. The FAE fan can be mounted anywhere, but the ultrasonic should be piped in to the first tier's wall. This way the moisture from that's being pumped in doesn't fall on your projects, it rises up with a fan. I have a fan on the bottom shelf that keeps the moisture from doing that. Really, it doesn't matter if you have a fan, in which you should to keep things evened out in there.

The fan is on a timer to come on once an hour for 15 minutes.

thanks for the pics, helps out alot. as for my first pan, its finally pinning. i seen 4 pins in 3 locations (one pin was growing off the stem of the tallest pin). i added 6 more pans today, the other 5 of the 12 were smelling sour or showing a lil bit of green. the small test one that i thought i seen green is still incubating but not showing any green at all. also, for my studies, none of the poo/straw has shown the green meanie, while the ones with un-pc'd verm are showing it or smelling sour. I think my conclusion is that the verm i have needs to be pc'd for it to be usuable for mushies, whether that be casing layer or rez effect. i cased all with straight coir, will that hurt at all?

[eatyualive]

it could be possible that your airflow is way to high. this tends to happen. foaf generally keeps rh around 98-100% until pins develop then dropping it to 88-90% through the fruiting cycle.

what is your timer settings?

foaf finds that you can get a chamber that size completely working with only 20 minutes every two hours. or 10 minutes of humidifier and airflow time per hour.

here is an excellent timer. it has 14 on and off settings a day. it may be something as simple as lowering your airflow. if you find your casings are drying out too fast. yes you can mist, but you want your airflow a bit lower not to dry anything out. especially when it comes to casings. if your fruiting cakes, keep your rh at 100% at all times.

this is available at home depot for around 20$.
Intermatic Timers - Consumer Indoor Timers - Digital Timers - DT17C

sometimes you can eye the rh just by looking at the condensation on the sides. id say in your pic above you are at or close to 100%. the sides are drenched. does your humidifier push out heavy airflow?

but this isn't always the case. ill show you a pic below of a chamber that has 100% rh and you can't even tell by looking at it. it has very slow airflow and nothing dries out. in fact, misting doesn't even need wasn't even done on some of these trays. if you have more airflow in one chamber than another, this may have to be adjusted. but in this case. it all worked well.







if it is your airflow, you may need to regulate that by a timer.

then when you get everything working perfectly. you can change the timer setting to drop the rh a bit.

although from the way the coir looks in the pictures. your moisture level looks to be fine. so this may not be the problem it may be just a matter of waiting just a bit more till something happens. and now after reading your last post, looks like everything is working for you.
