I think the only "cheap" LED brands worth even messing with is Mars Hydro and Spider Farmer. Growers Choice have been great to me and my plants. I personally bloom under HPS and probably will never switch until I see in person a LED produce better quality weed and a similar yield. Yeah yeah LED can get 2-3 pounds but hows the weed probably Big Bud or some mids.
I think a lot of people buy into the price and hype then are ashamed to admit they fucked up cause they got milked $10,000+ when they could've spent $2,000 on HPS. My buddy says his 680 watt LEDs are pulling 3 pounds per/light dry but I've yet to see it. He just regurgitates shit he heard from the grow shop.
