I think that the future is in LED's for grow, but is still off in bud production/ yeild. but if your set in those boxes, you are set. I know people that use em and are happy with what they have comming out of them. I only know of one person using the LEDs and hes usuing the bigest UFO type, and I do notice a differance in yeild (less yeild), but he also says that the electricity bill is almost normal, as in not much more than what he pays regulaly when the box is off. The people I know that use these boxes all share clones, and usualy keep one mother, but only for a year or so, and their mothers are all in soil. Always keep your mother in soil, after a year of hydro even the best flushed system can get root, and algee problems. But I have also seen mothers in a hydro unit. Also Indicas are what you wana grow in their, which is probly what you are going for anyway, I am an Indica guy my self, the sativas give me a racing heart kinda thing sometimes thats not to cool.
