seagu said: I am talking about a martha and or grow tent not being completely sealed inside a house with the humidity mushrooms require being pumped into it. I just have a shelf on a plastic tray with a plastic sheet thrown over it. The exhaust pulls the plastic tight and seals everything. The humidity doesn't even go out the intake. It goes right outside. So my room has zero extra humidity. I took measurements to find out.
My fan speed is probably overkill for a martha. So what you are using on high speed is probably good? Maybe? I have 2 others I probably could have used which are some 156 CFM computer fans built for high humidity. I forget all the numbers on space and stuff but my 210 CFM one should be enough for a lot bigger space even going based off equivalent numbers Andrew uses successfully. But this is a more compact area with less free space wiggle room for CO2 buildup. I have noticed for example because of how I cut the bags when it comes to 2nd, 3rd and 4rth flushes they stipe out some because the bags start coming up creating a sort of air pocket. 1st flush doesn't have that problem since the bags are right up against the sub. Maybe turning my fan up would solve that too. dunno. I am actually going to try some other things first. And I probably won't do 2nd flushes anyways for Blues. And I am using the same type of shelf gr0wer uses successfully for small grows with just a computer fan or something, so there are wide parts of the shelf adding to all this that can help to create CO2 pockets. But he does it. He might cut the bags differently for in there. I dunno like I said before still kicking the tires testing things out for my configuration. Which is different than his. And I am working on a design to make it far different than I have seen anyone doing a martha do to eliminate all air pockets around the bags. But who knows someone might have done it. 
I would pipe the spores directly outside. Everyone I have heard of using a filter says it gets clogged too quickly. Even Andrew mentions that. But if you are not growing that much... meh..
The fan you have is piping directly in from outside? Or outside the martha? Or outside the tent your martha is in?
Use some nails to hold the plastic down. Use one of those computer fans as a circulation fan inside the tent. Everyone that does not have a circulation fan will have co2 build up around the mushrooms. Don't have the fan blowing on the mushrooms just have it moving air around.
Yea already tried that. It is how I set it up from the get go. One of the 156 CFM fans is used as a circulation fan. Maybe I just need to speed up my exhaust fan. Its on low. I am working on setting it up so I just stack the bags on top of each other in the middle/back on a rack for each shelf so that its a wall of shroom bags with the fruit growing directly over the holes on each shelf. So that it fits the exact same amount of bags as if they were sitting on the full shelf. Then just pipe the intake and exhaust across the fruit's side of the bags. I have all the materials to build the extra shelf on each shelf for free so.. why not. I would rather have side fruiting bags anyways instead of top fruiting. And like I said its only a problem after the first flush when the bags start coming away from the sub creating a little air pocket around the base of the shrooms that isn't there for the first flush. And since I am probably not going to keep the bags after the first flush.. meh..
And there is zero need to hold the plastic down with anything other than the exhaust fan's suction. Its holds perfectly. Provides an air and water tight seal. 9'x12' plastic tarp sideways, folded over the top and wrapped around the sides. Perfect size for those HDX shelves. 5 shelves with 4 usable.
-------------------- Plan to win or you are planning for failure. Don't let anyone tell you you can't do it. Just figure out the solution. Even if that means banging your head on a wall until the solution oozes out of you.

I think they're liking the changes

tweaked it just a bit more, put everything on the second from top shelf because they seemed to be drying out a bit up at the top so close to the exhaust, and reoriented the circulation fan to blow at the back wall at an upward angle, seems good.
vid of the air movement, hopefully you can see the mist moving around. this has to be sufficient, right?

Getting there!! Second flush from the bags:

These are the best from the bucket, they seem too wet though, and possibly bleached by my light. It's an LED grow light at 25% power, and the ones closest to it have definitely grown the weirdest. Thinking it's time to get off my ass and get some lower powered lights in here.

Great work guys keeping the thread going. everything is really informative.
One thing as a beginner grower it's hard to wrap my mind around how much FAE it needs.
At first, I was putting an aquarium pump in the tent, thinking it would be enough. I was so wrong, these fungi produce a hell lot of Co2, it's crazy.
I realized how much co2 was building up, by putting a Co2 meter in the tent and watching the value climb up:

These next set of photos are from calendar weeks 2-3 of 2020, Growing and experimenting a whole bunch:






next set of photos are a set of experiments of growing oysters out of the greenhouse tent, surprisingly they turned out much better looking (even with less air humidity), so now i know for sure that there is a FAE/Co2 problem in my tent:

Next I did some modifications to my set up. got a larger 10 disc fogger, on a floating bed so I can fill the container full of water while maintaining optimal water height for the foggers to work correctly.
i've also rigged it up now, so the humidifier works by pulling outside air into the tent. so when humidifying it's also supplying fresh air, as opposed to before, where it was recirculation air inside the tent to humidify.

this week I had one of the stranges grow, 1 giant oyster mushroom from a sawdust block:

Wow that is one hell of an oyster !
That's interesting to see the co2 readings, I've never owned one of those.
Been noticing a lot lately how even the growers with major accounts (whole foods, my local grocery store chain) still seem to have trouble growing oysters. I should've snapped a pic but I couldn't believe they were even selling them as leggy as they were...

Why?
Unless these oysters were started from spore which would be a really odd thing to do, the culture should already be an isolate so cloning would be pointless. I think you're thinking of cubes

True that forrester, no point in cloning as it's an isolated strain. Unless there's something i'm missing.
I initially got the strain by clone a store-bought oyster mushroom. so all oyster mushroom i've grown thus far is from that one strain.
i'm still amazed by how big it was. i wonder why it grew like that, i wanna try to replicate the grow.
the sawdust block used hardwood eucalyptus as a base, 20% wheat bran, 2.5% gypsum. when hydrated the block weighted 1.5kg.

it's common for later flushes to make fewer, but bigger mushrooms as you probably already know, but yeah other than that it's kinda chance I think. Don't think I've ever seen a regular oyster (not king) that big!

So a bit of update. my latest flush looks a lot better now.
block 1:

block 2:

So the new setup has helped a lot. With the humidifier outside the tent. every time it goes on it's bringing in fresh air (oppose to recycling internal air).
one question in reference to the above photos, in your guys/gals opinion, do they look ready for harvest?

Yes they look ready. If you watch the very edges of the cap, when they flatten out like that and point straight out they are ready. If you wait a couple days more on those you will see those edges curl up and get a little wavy. You wanna get em before they do that.
