I AM ALL FOR THE SWITCH, AND FORUM. Once i crop this last harvest then its all LED from here on out. LOL, after seeing my friends crop using LED's I would be an idiot to keep using MH or HPS. Trust me, i thought HPS was the best thing since sliced bread until my boy made the switch. Electric bill, GONE, heat issues, GONE, leave burn due to lights being too close, GONE.. The crop was bushy, good consistent growth and cropped 1.6 lbs more than he usually does with the exact same set-up. I will say one thing, they are expensive to get the set up you need, but you WILL MAKE THAT $$$ BACK ASAP WITHOUT THE HIGH electric bill.
