LED GROW LIGHT by /u/entreps
LEDs are wired in series and the rings are independently powered. LEDs used: 3W chips, 445nm, 460nm, 630nm, 650nm. Veg will be for the inner 3 rings of the LED, Flower will be for the outer 2. During veg only the inner 3 rings should be turned on, once in to flower I will have both switched on. Each driver can handle up to 18x3w LEDs at 600mA and provides AC85-265V Constant Current, perfect for my needs. I'm using a 230mm fan, 150 CFM and 26dBA.
