Dragon, what we could really use is a definitive guide to growing with LEDS that was not written by someone selling LED grow lights. They have me so frigging confused that I gave up trying to figure it out. But i can share what i have figured out about florescent, HPS and Metal Halide and maybe you can translate spectrum into LEDs. The best results for me were blending the two lights. The plants that were in the area where both types of lights covered were the best producers (not that I was really trying to produce pods). Most LED grow lights were made with growing weed in mind. In that genre of plants, the thinking is (I might have this reversed) red spectrum for flowering / fruiting and blue spectrum for vegetative growth. From blending Metal Halide (I think red spectrum) and HPS (I think blue spectrum) I got the best results. Maybe the same is true of LEDS.
Here is the thing, most of the peppers you are probably growing are pendulum hung / shaded by the leaves and most artificial light has a horrible time penetrating a canopy. So most of the techniques developed by weed growers wont work as well. Generally, they are going for a single large bud at the top of the plant. Some even promote trimming away the fan leaves. Not a good idea for peppers.
So I imagine the biggest benefit to LEDS is side lighting because they can be placed between the plants and are not likely to burn them. Seems like a whole lot of money to grow something that you do not have to hide indoors. I do it for starts but the idea of paying that much money to grow the pods is off putting in the extreme. Am poor folk. Would rather pay for groceries.
