Does the plant cabinet need to be inflated? Need to vacuum?

Hi! :) That's amazing, sounds like you as well pump air into the tent as also suck air out at the same time, right? Normally with tents of that size, you just need an exhuast fan, so then the tent will vacuum (the siddes of the tent will be sucked in if closed) It actually doesn't matter if it inflates, as long as there's air going out through the carbon filter, and coming in somewhere else.. ;) The inlet fan probably works stronger due to less devices attached to it. Grow strong!! Yours in love, SF

Keep the sock over it and it will help filter the air coming into the space. You want more air being extracted from your grow space. Good Luck Bro 💪
