i have 6 plants growing in a 3 ft x 2ft x 2ft box that i put together with a lil help from a trustworthy friend..im working on getting advice on where i should position my 400w and how should my vent fans work? i'm thinking of buying 2 4inch fans F.y.I.. the two big pots are Jack Herr and Purp and the 4 tiny ones are the unknowns
As far as your light, just keep it at least 12 inches from tops. Find the best spot where your light will be utilized most efficiently. For your fans you want one that will suck hot stagnant air out at the top of your grow space, and another fan should go on the opposite side near the bottom of your space to suck air in, around your plants, and then up and out of the space. You want a bigger fan for intake, more air going in than going out. Hope this helped.
