The proof is in my grow guys. There were no popcorn buds in my last 2 plants. I did over crowd the tent in the beginning but I got a huge yield from 2 plants.

I have 4 plants in there now under a 190w LED and 80W of CFL for heat. LED panels have come a long way. I got 5+ ounces of quality weed off 2 plants, dry. And they didnt even get a proper grow because I had to kill off 7 ! plants cos the tent was too cramped. I downgraded my tent you see. 2 plants began to win the fight for the light so after a while I realised that I would get better bud if the 2 big plants didnt hve to fight for the light. Anyway, in only 6 good weeks (6 cramped weeks) of flowering I got a respectable yield from just 2 plants. Im going for just 4 plants this time round. I expect to do very well this time.

Just be sure you don't buy your LED lights off eBay. 90+% are rubbish.
