Growzilla could be an option, but you'll be running 1,200 watts in that tiny space. With that much power in that size area, you could do an entire grow from start to finish with the light hanging at it's highest point and never lower it. That, or you could just go with a single 1000 watt and spend less money for the same results.Either way it's a waste of such power. You would never be able to recognize close to the full potential of what that many watts can do. Think of it like this : 1000 watts will cover an 8x8 space with good results. If you are still gung ho about running 600 or more watts in there, get ready to spend WAY more money on electricity than you need for that size grow or try to come up with a larger area to efficiently utilize the watts. Am I making sense?
