I don't understand why people are so stubborn and refuse to accept the information DrBud is giving us. It's the numbers and the methods, you people are getting more caught up in the lights than necessary. h3ad has some very good points about the CFLs, but seriously. SOG is always going to be the most efficient way of producing bud, and this is like SOG on steroids. The plant numbers are crazy, and the only way I would ever try them would be if the laws were dramatically changed, or if I lived in the middle of the woods on a mountain off grid.
