all depends on $$$ if you have the money go for good quality led, what size is grow space, how many plants etc etc, 90watt led for smallish, depending, lil more info on grow area please
cfl's are cheap and work great.....u just need quite a few of them and they produce a lot of heat
led's are expensive in comparison, and also work great but dont produce nearly as much heat
I would say CFL's are better...although many people swear by LED's. I think it's really a matter of preference. Is this going to be used only for Veg? Or flowering too?
