I have been a fan of the ts series lights for a few years now. If u wana see what this light can produce head over to thc farmer and look my name up��buddernugz��and look for my grow diary called��2lb plant 2nd attempt no co2��..the plant on the left of that 4x4 is grown with a 1400$ optic led slim 650s�.the plant on the right of the 4x4 is grown under a mars hydro tsl-2000 and a mars hydro sp-3000��the quality on the Mars hydro side is far better than the other side�.both plants were grown from seed with a 9 week veg under 24hr non stop light, coco dtw and without co2. Both plants were vegged under a ts-1000 for 5 weeks in my 2.5x2.5 tent�.then moved into my 4x8��..I have yet to pull less than 14oz off that light without co2��don�t sleep on these tsl-2000s if your looking to cover a 2x4 or a 4x4 area��I�d sooner light up a 4x4 tent with 2 of these tsl-2000 lights and pull just under or just over 2lbs off 1 plant than I would buying a light that�s going to cost me 2-3x as much to cover the same area and pull the same weight��..their explosive in veg and diabolical in flower��..

What's questionable on the LEDs because of ones I tried before. Was very pleased with the first crop. Second one even more so. First time trying the autoflowers and they really kicked ass. No problems with leaf burn or heat best grow yet
