I have a small cabinet in my place... Roughly 46" tall, 30" wide, and 19" deep. Have been considering putting a 240watt led inside of it and some ventilation. Is this space big enough for growing 2-3 autos at a time and if not how many? Suggestions? I'm not sure about the led yet, hoping a 240 would be big enough but also understand many folks don't like led. Seems like some people have awesome grows with them though like Seymour buds and a few others.
