Air Exchange during Colonization
    #3660489 - 01/21/05 09:22 PM (12 years, 10 months ago)

I was recently told to let my casing colonize without air exchange. Is this accurate, or should I still be fanning a few times a day prior to fruiting?

What I would do is incubate them for three more days until you can see myc growth on the side of the casing.(If possible) But then again the amount of time depends on the substrate and the size of the container. Wrap it up with aluminum foil and wait it out.


Though you can't go back and make a new beginning. You can start today to make a new end.

You don't need to fan them during casing colonization, however a layer of tin foil with holes poked in it or equivalent (saran wrap w/holes) is just right. The idea is to let C02 do it's thing for the colonizing mycelium, but not to create an moist airtight contam breeding ground. Allow it to breathe a little.

Sorry to bust in on your thread here bemmers1, but I have a ? that kinda goes along with this....
Latly I've been thinking about putting some (2) holes into the side of my FC, and covering with tyvek. The plan is to allow the CO2 to fall out, if possible.
I'm not a fan of the small pumps, and the like. For 2+ yrs hand fanning has worked like a champ, with this being done around the usuall 5-6x a day. However when i'm not around I think it would be a good idea to have something to allow the exchange to happen.
being there would be no posi. pressure, do you think the tyvek will allow this?

I highly doubt holes w/Tyvek will replace the stagnant air inside the chamber without introducing fresh air, not only that but the casings surface area, mainly the stagnant air pockets, also need fresh air especially during pinning, this also keeps the breeding grounds for contams down (they love stagnant air pockets :wink: ). A simple filtered air pump on a timer will give you that FAE but the fanning is what really moves that air around :wink: Thats why the automated setups (coolmist/ultrasonics) work so well they create airflow.
