Using the Migro Led lights i have produced the best quality i feel i could have. the stuff is sticky and covered in Diamonds. yes diamonds i tell you. I can't go back to HPS now. The saving in electric is a bonus. I thought the claims of getting more than 1 gram per watt were rubbish. Not anymore, I'm a believer now. i think after 3 grows of getting similar yield, i'll shout from the mountain tops. I don't want to yet incase this was a strange fluke.
