Oyster Grow Suggestions?
    #19289377 - 12/17/13 04:24 PM (10 years, 1 month ago)

I´ve got a 18¨x36¨72¨ humidity tent here. I have an exhaust vent with a shopvac hose running into it to pull out CO2 set on a timer to run for 1 minute every 2 hours (This thing is powerful). I have a squirrel cage fan attached to an intake vent which pulls fresh air from outside into the chamber. This intake fan runs on a timer for 1/2 hour every 2 hours or so, along with 2 vaporizer style humidifiers (they add heat, not too happy about that) and one cold humidifier. One 36¨ grow-lux (I believe) fluorescent light fixture runs vertically along the inside of the chamber.

My temperature levels are within reasonable limits, and my humidity levels seem fine. I´ve only got some cakes in here presently, I´ll start putting much larger bulk in there soon enough but I figured I was just testing the chamber beforehand. My only concern is fresh air exchange and removal of CO2. Do these fruits seem to you like they´re lacking FAE or are they just small and don´t have large caps because of the extremely small amount of rye substrate they´re growing from?

Species doing best are P. ostreatus var. Columbinus, which are located on the top level of the chamber. The other species (P. ostreatus and P. eryngii I believe) are located one shelf below, and seem to be pinning but growing much slower. I have read mixed opinions on the settling of CO2 to the bottom in chambers. I attribute the differences in growth to the different strains, not the settling of CO2 which I assume does not occur, especially in an environment which the intake and exhaust is frequently moving gases around.

Chamber:


Intake from outside with squirrel cage fan inside the chamber (thinking I should move the fan outside the chamber)






Exhaust via shopvac (shopvac is inside the old shotgun fruiting chamber which helps minimize the blast from the shopvac exhaust through a more equal distribution of air):






Mushroomies:








Thoughts?


Thanks,

T

You don't need the exhaust fan. It sucks all the humidity out. Just run the squirrel fan more often  or ideally put it on a dimmer switch and dial way down. Then leave on 24/7.

If I don´t have an exhaust fan where is the CO2 going to go?

It is displaced by the fresh air from the squirrel blower.
