I run QB boards the 550 r spec wood be the one I would go with. R spec is with red far red spectrum and will be as close to your 1000w lamp without the heat and 1/2 the electric cost.
Someone mentioned the 320 r
spec QB boards you wood need 2 for a 4x4. That wood be what I'd run. The 550 will work too. Look to your wallet for best choice.
There are Alibaba options as well for less. Basically Quantum board knock offs for 1/2 price.
Also there are COB led lamps as well.
Led gonna replace the hid lamps due to efficiency and run cost.
Also Gavita owned by Monsanto/Scott's <spit> they the best hid makers and now making led lamps. Try and avoid.
thanks for the info. im definitely set on LED
im just thinking, since ill need 2 320's for a 4x4, would it make more sense to just do 2 3x3s with a 320 in each?
in one of the sticky threads i saw that for LED the bare minimum for productive flowering is 35w/sq ft..
so a 4x4 tent would require 560 W of LED which would make the 550 or 2 250's still not enough light, correct?
