I have a 5 ft high 2 ft deep and 5 ft deep, im using 20 lb co2 tank with everything for it except a controller, but i plan on turning it on when lights on and turning it off when lights are off. I know when things are at thier best level i can increase my yields to 30 percent. But will i be ok with no controller? The lights in using is 600 watts LEDs and the room is air tight.
