im trying to part out two arrays with the best ppfd per watt for one with 12000k, 425 nm 440nm and one with 630nm and 660 nm. I don't know anything about heat sinks needed per diode or how to run them for maximum life while still getting a total of 1500ppfd on a 2.5x3 cabinet scrog. looking for bud depth layer (not starkly pruned below) of 2-2.5 to feet. I think a combination of lenses 90 and 60 degree would be good but I have no idea.
