I am in the process of planning a new grow rack, and I don't want to use lights that draw a lot of power. I have done a little research into LEDs, originally for my reef tank, but now I have started to wonder if LEDs could be used for growing CPs? Knowing that 5000K to 5500K is a good range for plants to grow under, would it be possible to replicate this with LEDs? I think that you can get LEDs that would do something similar for aquariums, but would these fixtures work for plants? It'd be really nice to have much less heat transfer to my grow space as well as use less power. Any thoughts?
