small sealed room - oscilating fan, or no?

I have a unique little room that i'm not sure how to handle, yet dont want to wait for the green meanies to grow and learn from my mistakes THEN. i seriously refurbished my bedroom closet. 5'x5'x10' in dimension and is coated in Killz (3 coats!) and every crack sealed with silicone. I'm intending to use RR's shotgun fruiting chamber for some of my cakes, and Doc_T's mini- mono tub hybrid (combination of shotgun terrarium with no holes in the bottom, just filled 4" with h-poo/vermic) Just to compare results first hand.
the room is heated to a constant 75degrees with a space heater, humidified with an vics ultrasonic (15 min on 4 times a day), and i'll have these tubs on what is now the top shelf, mere feet from a 5000k 100w equivalent compact fluorescent light.
QUESTIONS: RR states that his tubs need fanning but a fan in the room may diminish fruiting chamber humidity by providing too rapid of FAE, and i'm sure so it goes for the mono tub. But if i DO NOT have a little bit of a breeze in this very small, closed in space with a humidifier going - will i have to worry about cobweb mold and trichoderma due to high humidity and no air movement? *and do the no rapid FAE rules apply for these fruiting chambers if the relative humidity is already at a certain percentage. Say... 60-70 percent ambient humidity?
also is there any detail i'm glazing over with this setup scenario that may be counter productive????

With a completely sealed room like that I dont think they will get enough air. I heard that a SGFC is best in a bigger room in open air so the air that circulates in the room will give it enough FAE. I remember somebody saying closets are not the ideal space for SGFC. But that is just what I heard. I have had successful grows in a closet with its door open.

i always wait till i have subs to figure shit out and make my adjustments accoringly, sgfc's will suffer from fans but mono's like them, maybe once you have subs in there point your fan away from it and see how things go but

IMO, the SGFC requires static external conditions. I think fanning it from the outside will ruin what the heap of perlite is trying to do.

yes it will, but mono's can be adjusted just loosen up the poly and you may have to let go of the "set n forget"

after seeing the results FrankHorrigan has been getting from his monotubs i'm seriously considering converting everything to that style anyhow. having both my rye grain jars AND fruiting chambers in one room i'm just overly paranoid of contamination spreading around. But with the drafty 20% relative humidity of the rest of the house, this little room may be the only chance i have of getting a crop. I'll leave a shotgun terrarium out in the greater room to see if i can compensate by misting 2-3 times a day to offset humidity problems. do SGFC get smaller yields than mono-tubs when dealing with bulk substrata? *better suited for PFTek i'm guessing since that video is where RR decided to include that particular fruiting chamber. SO MANY DAMN OPINIONS TO READ ON THIS SITE!!!! and to make decisions even harder, everyone has amazing pictures to back up their claims

just get your sgfc out of there, it can handle the low ambient rh no prob, yes bulk trays can kick ass in a sgfc as well

thats because the set up/style is really irrelevant, if you can get proper conditions in any of them you will reap the rewards regadless, don't fret about contams until you get them or you will turn into anne all jokes aside Quote:
