Check for quality not cheap. This is not Mh/HIP were talking about. We want quality and tight buds so you need 300watt Pro Led Grow Lighting. Its cheap now to what it use to be $10 dollars for one led and you have 300 that is costly then now its a $1.50. a led alot cheaper.When picking the led you need to make sure it is Bridge Lux led from Ameican company it does all blue leds,orange and white to get your Tri-band or Quad-band full spectrum to get a good quality led the Epistar a Chinese led company for the Red band.I recommend the 660nm red,462nm blue,and 612nm orange star burst ,to get this as a 8:1:1 your plants will love it and it has 8 cooling fans so it controls the heat that it generates so all you will need is a couple 6" air-king fans to move the air and invest in the Co2 Boost bucket your buds will double in size an it will pay for its self.No more high electric bill. No more heat issues,ballast making all kind of noise and draws so much heat ,ducking,Air flow hoods 6"...etc.Here is the best price vs quality 300watt Led grow lighting $695.00.Check out he web-site and keep your money that you would be paying out for electric bill and pay yourself plant more sea of green.The site I recommend is waterpijpen, waterpijp, vloeitjes, bongs, hasj pijpen, headshop - Grasscity.com any questions give me a call to figure out your grow area.I use a 76x76x76 grow tent and what a great environment to grow in.
