I really love the way LED's work with my seeds and clones, but there is nothing like hps for flowering imho. I've found some great LED products though (3 watt models), but they're very expensive. I know they're cost saving in the long run and offer low-to-no heat, but I just cant stomach the $1200+ price tag. I don't mean to make it sound like its not possible...I'm just not sure its worth it for me just yet. (prices will come down!)
