Marijuana LED Lighting

I have been growing inside since 1984, as an electrician I was fortunate enough to get several HPS and metal halide fixtures, 400 watt units, given to me during a plant modernization. I raised many nice crops with these lights but have always had heat and cooling issues. Very hard to use in a small enclosure. This summer I purchased 4- 300 watt LED fixtures with 3 watt led’s from EBAY. I bought 2 fixtures for vegging, they contain more blue light and 2 fixtures for flowering they contain more reds. They are 90 degree fixtures. I built a 4 ft.x7ft.with a 7 foot high ceiling.enclosure, 1- 4 inch vent fan.Room stays at aprox 84 degrees with 4 lights running. No outside venting needed. Cost for 4 fixtures, $96.00 each, free shipping. Fan $14.95. In 6 weeks vegging plants were aprox 24 inches tall, went to 12-12, plants flowered within 8 days. Harvested super skunk in 51 days from start of flowering, OG kush in 54 days, purple haze and white wisow at 62 days. Total of 16 plants. Shortest grow time ever, biggest harvest weight wise from 16 plants aprox 25 to 30 % higher than with halide or HPS. Buds totally frost covered and potent, taste is great. No THC break down from excess heat and plants can be as close as 3 inches with no heat damage. I grow using a red blue red blue fixture on both veg and flower. Power draw slightly higher than 600 watt HPS for all 4 units. These 4 300 watt fixtures give you more useable light than 2,000 watts of halide. Over all LED’s have given me much larger harvest, more potent better tasting herb in a 2 week shorter grow period than I get with HPS or metal halide and cheaper to operate. Also plants can grow 2 feet higher in in your grow as you do not have the lights 2 feet above plants= way bigger yields. Hope this helps, good growing.
