so u got no fans or any blower/sucker, it gets Fae due to the pressure of heat rising and cold air sinking,is what ur sayin, just so we all understand how thats workin. well u certainly thought this out very well, what sparked that idea for ya? I got a quick question for ya RR, have u ever heard of skinning the top layer off after u pic a flush. this is pertaining to a 18gal mono using wbs,h-poo, and straw. my guy grows aswell but he said that he skins off the top layer so that the mycelium can recharge/regrow and produce more pins. i never read or heard that anywere before and i figured u should know since you are the Yoda of this great hobby. Sorry off topic just wondering what ur opinion was.

not so much that they dont need any light but they need alittle light with fae to get a good pin set goin. ive read that the light is what gets the pins goin but then other ppl say its the fae itself that does it. id say 2hr min of sun and they should do just fine. I turn my light on at 7am and off about 7pm, so its a matter of what works for u thats all.

Correct, no fans or blowers. The FAE is natural and based on the fact that if there is a temperature or pressure differential between two air masses, there will be flow between them. This also happens to be the exact same engineering principal that makes the shotgun terrarium perform so well.
The large surface area in contact with the earth also negates the need for any heat or AC. So far, I've observed the grow room over a 80F temperature swing(It's been as hot as 105F outside and as cool so far as 25F) and the internal temp has not even varied by 1 degree. It stays at 58F. I have no reason to suspect that this winter when it's -30, it will change from that same 58F, which is ground temperature at that depth.
Don't cut the top layer of substrate off after a flush.
Light is required not only for pinning, but for proper mushroom development as well. Mushroom mycelium derives energy from light. Mushrooms grown without sufficient lighting are weak, thin and have little weight compared to mushrooms grown with proper lighting. That's why I have over 400 watts of 6500 Kelvin LED lighting in my grow room. It's as bright as daylight in there, and the walls are painted bright white to reflect the light around the room. RR

ok so dont cut the top layer off, can i ask why i shouldnt do this, could it get inffected if so? ive noticed that my mycelium turns slightly grey,its not contamination, im not sure if this is due to spores falling or is it possible for the mycelium to die/stall? if so what can b done to prevent this? Has anyone ever had condensation build up on top of their mycelium to were u can see beads of water allover the top. I think this is causing my fruits to grow hollow and thin, but im just not sure.. RR, you said that ur using 6500 kelvin led lighting. my question, ive been using this light bulb, its a n:vision mini spiral lamp fluorescent bulb 120v-19watt 5500k and it says daylight on it for kind of light produced, is this one ok or is there another one i should b using. only askin cuz u said that improper lighting can cause thin and hollow fruits and im wondering if this could b the reason.

5500 K is fine. If you buy another one in the future, 6500 K is a bit better, but don't toss out your 5.5K CFL.
Condensation on top of a bulk substrate is normal. It doesn't cause hollow stems. The most likely cause of that is growing at high temperature. Hollow stems are a sign of very rapid growth, and higher temps can stimulate rapid growth. Fruit quality is better if you'll grow at normal room temp.
It's best not to disturb your bulk substrate. There's nothing to be gained by cutting away part of it. RR

ok thanks for ur info and responses.. my grow room is normally around 76-80f, it varies cause of the summer heat. although i did notice that my mushies grew alot nicer in the winter by me, was alot easier to regulate my room temp, my house is an older one and i dont think its insulated very well cause its always hotter up stairs by like 10degrees, even when i got the ac going its frezzeing down stairs and much warmer up stairs so i cant wait till winter to c how they grow. If thats the case i think i gotta work on insulating my attic better,and hopefully that works for next summer.

So is it necessary to have the light on top of the mono or could u place it on the side if u didnt want to put the plexiglass in. I got two bins stacked and i have a 20 inch bulb just propped up/standing up on the side of them, think this should b fine or should i spend the cash and get the plexiglass.
Also is there another way to install the plexiglass on the lid without using gorilla tape. i have been noticing that some times there is green mold growing around the edges of the tape and on the lid were the two meet on the inside and i have to go and strip it off and clean it real good and re-tape it but i find i gotta do this after about 2 uses (full cycles)and that damn tape aint cheap. Anybody got a different way or use something different to secure the p-glass?

You don't need to tape or otherwise secure the plexiglass. Just lay it up there. Light from the sides is fine. It doesn't need to come from the top. RR

i got a standard cfl that says 60 on it would that be sufficient light? or would putting it in sunlight be a better option?

It's probably a 15 watt CFL. More important than that is the color temperature. If it's a 'warm white' it won't do much good. Look for a CFL that says 'cool white' or 'daylight'. If it has a K rating, look for around 6500 Kelvin. Put the light as close to the terrarium as you can get it without causing heat buildup.
Sunlight is always better, but avoid more than a few minutes per day of direct sunlight. RR

So do you advise a couple minutes of direct sunlight a day? I was going to use indirect sunlight for my terrarium.
