Bro, I am posting the LED experiment myself. I ran into the same immature bullshit on my blogs. Is it working? Yes. Is it cheaper? Yes. Does it produce as much bud per plant? almost. LEDs are the way of the future. I am flowering my AK-48 from nirvana (4 females) and the top buds are all up in the led light, doing GREAT. I had to plug back in my MH bulbs to make enough heat for the winter cold snaps! Everyone thinks there method is the best, but you give a man a smoke, he gets high for a day, you teach a man to grow, he gets a lot of people high, and teaches himself and others to grow.
