fan how often and how much. are we talking do it lightly or cause a mini-hurricane inside the terrarium each time you take off the lid to fan?

By Nanook of the North (Nanook) on Tuesday, October 02, 2001 - 12:47 pm:

All you need to do is fan enough 2-3 times a day to completely exchange the air. C02 sits in the bottom of the chamber because it is heavier than air. Fanning removes the C02 and exchanges it with fresh air. No hurricane required.

If you are seeing lots of White Fuzz, then increase your fanning. 4-6 times a days is not excessive.

I just birthed my cakes to the terrerium, do I start fanning and misting now? or wait to see pins? I have perlite on the bottom also.
thanks all,
Merry HOHO

You want to start fanning. I mist the sides of the rubbermaid after im done fanning to help get the humidity up. Hope im not to late! .

Pam... Sounds like some shrooms will be visiting around New Years! Happy Holidays!

if you have no pinning yet,
then only fan once daily, you want a little co2 buildup, it helps trigger pinning.
cakes only, casings trap co2 internally to help pinning, but cakes do not.
mist the sides of terrarium when you fan.

give them light, and wait...

And if you're setting your cakes directly on the perite, don't. My harvests have increased nicely after Nan advised me against it. Using a ten gallon tank, I just pour one layer over the other, v over p, and carefully sock the water to it. The walls stay dripping, no need to mist.

By Hatcher (Hatcher) on Saturday, December 22, 2001 - 08:09 am:

And I've always ran a six inch airstone,in the open air,for good measure. Can't say if I helps or not, probably not w/o some air movement,but it looks cool mounted via velco in my tanks!:) Wonder where a man could get a fan small enough for a tan gallon aquarium, like an inch and a half, that could be ran on 110? And fan whenever you can.

try edmund scientific, they have some small fans.

By Hatcher (Hatcher) on Sunday, December 23, 2001 - 06:35 am:

Thanks for the tip...think I'd be worth the effort?

By onediadem (Onediadem) on Sunday, December 23, 2001 - 08:59 am:

I have 2 terreriums, one has cakes, the other has trays of cased birdseed, with 50/50 casings. do I only fan these once a day also until pins? do I need to mist these? they too have perlite on the bottom of chamber.
thank you

fan the cakes once daily until pinning.
casings can/should be fanned 3-5x daily.
only mist the casings as needed to keep moisture optimal, stop misting directly once pinning begins.

Hello all,

I have read that after a week of air exchanging by hand the terrarium that you can ease up on it.So if I have been following a regimen of twice daily then cutting down to once a day would not hurt?My real question is this.I have noticed that after doing the twice a day shuffle that when I reduced it to once a day AFTER a week or so I got larger shrooms in the following flushes.Is this because of the reduced fanning?Or is it simply that the proceeding flushes are working from a more established mycelial network?


By Snoopy (Snoopy) on Wednesday, January 23, 2002 - 01:59 am:

For the record... I barely fan my cakes ever and I get plenty of mushrooms, I think fanning really only matters if you have a small terrarium.

By Hatcher (Hatcher) on Wednesday, January 23, 2002 - 08:50 am:

I don't believe I'm the only one here that runs an aquarium air pump for good measure. Mine to a 6" airstone velcro-ed high in the tank..

Co2 rich terrariums ain't gonna kill ya. We have all heard stories of the guy who left for a week, came back to an awesome flush...

And nope hatcher, my buddy has one to....

The most important thing about air exchange ( imho ) Is for contams. fresh air equals less contam chances.

So go ahead, cut it down.. Being a slave to your terrarium is only fun at first, then it becomes a MAJOR drag. But, do as hatcher and my friend do, and use an air pump to at least break up that stale air a little...

By Ron (Clubbenguy) on Friday, February 01, 2002 - 05:13 am:

The reason your shrooms were larger when you minimized fanning is that all of the oxygen you are relasing by fanning is holding all of the moisture. When you bring fresh air in....its is drier that the air already subject to perlite/moist verm, misting, so it has to pull moisture from the surrounding objects to keep all of the air at the same humidity level. Well, you guessed it, since mushrooms are 90% water, the more fresh air you let in, the more moisture needed, the less moisture for the shrooms hence less size. Hope this helps.
