Ok so im trying to set-up my closet so i can grow in it. The dimensions are about 6' by 5' and 10' high ceilings. I have a 600watt mh and hps light system already with the yoyos, a 6'' 240cfm fan for the light tube. A Hygrometer. A ph kit. GH nutes and fox farm organic soil. Im thinking i can maybe get about 9 plants? The bad thing is idk how im going to vent it unless i vent through the floor. But can i only exhaust without having an intake system? Any tips or constructive criticism would be greatly appreciated. Thanks
