fruiting question
    #5638566 - 05/16/06 05:37 PM (17 years, 8 months ago)

i have a 36" X 22" X 21" fruiting chamber ( FC) hooked up to an ultrasonic humidifier. inside i have three 21" X 10" bulk casting containers, as well as about 15 mini loaf containers on plexi glass shelves half way up.the humidifier is controlled by a 24 Hr. timer with 15 min intervals. ive got an expensive brass hygrometer to help me make necessary adjustments to the timer for a 90 95% RH.
my question is: while in fruiting in this set up do i relay need to worry about gas exchange, or putting covers on the containers ? i thought i had it made until i read in a post or article some ware on this site that i dont want to have gas exchange between the time of casting the cakes , and the time of pinning. will i need to turn off the humidifier and use covers those few days, or can i get away without it?
thank you for any input
trent

First off ur gonna want your RH at 85-90% not 90-95, yes your going to want to put some hole in to allow CO2 to escape, u can cover it w/ some tyvek or polyfill, or even microtape. And i think your confusing fruiting w/ incubating right after you case, whatever environment you did the jars in is where you'll put your trays right after casing them to let them colonize. Hope that helps.

opps i forgot to say that there is a 1/2" hole cut on the bottom. yes i know that i need incubation conditions right after casting, but my incubation chamber is to small, so i have to creat incubation conditions in my FC. i just have to block out the light and add some heat. what i want to know is if when the casting containers are colonizing in the sealed up,dark, and warm FC can i use my humidifer or will that mess with the co2 build up??

Remove the humidifier, because it isn't needed in a small chamber like that. Your trays will deliver more than enough humidity just by themselves when fruiting time comes. While the casing layer is colonizing you must have gas exchange. Don't confuse gas exchange with fresh air exchange(fae) which is one of the pinning triggers.

Just wrap the top of the tray with aluminum foil, then poke one or two nail sized holes in the foil for gas exchange. Unless your temps are below 75F, you don't need or want to add heat. I colonize on an open shelf, not in a container.

I have so many times already :frown:

Gas exchange: The ability to release builtup gases resulting from the myc's metabolic activity (consuming substrate). A result of this inability to release these gas creates EXCESS myc piss (metabolic by-products) which BTW is a normal process (myc piss) but an excess is not, it can easily stall a cake. (do not lick your cakes or leave your holes taped) :wink: Simply put it's an exchange in values.

FAE (fresh air exchange) is the lowering of the co2 concentration through the introduction of fresh air plain and simple. A good fresh air exchange includes the stagnated moisture pockets of the casing surface (microclimate).

PFTek is now officially outdated! :wink: Of course you can tape the holes during PCing if you feel the need but foil is all you really need. Just remember leave the tape off after inoculating, trust me that will save you a lot of headaches.

i just took off all my tape. except for the liquid culture jar. it has no protective layer of verm. so i left the holes covered. was that ok?

For now yes but pick up some micropore tape and use that instead to allow for gas exchange. I also just crack the lids loose slightly but don't forget to retighten the lids if handling them.
