LED lighting groups-a sponsor- has a full compliment of quality products. I picked a HLG 260 and it absolutely is the best for my 2x4 grow. I tried a 1000w Amazon LED and it was impressive light but not bright enough. I would need 4 of them at $112 =$448. One HLG 260 was $329 shipped to my door.
2x 2000w Aglex in 8x4 setup, 30" above the canopy. No AC, just good venting is required... Housing reaches about 32 to 36c on full use. In 7gal coco, drinks about 1.5-2 gals a day under this setup. 8w veg, 10w flower. White Tahoe Cookies.
