http://www.ctahr.hawaii.edu/kobayashik/supplemental.html Hello, I have successfully grown a dwarf tomato variety (Red Robin) under a combination of cool white and warm white leds in doors this winter. The combination used is two warm white to one cool white. That is the same combination you would use with fluorescent lights. I did not use any far red or low blue leds in this setup. I use roughly 50 watts to a square foot giving me approximately 4,000 lumens. You can use only the cool white leds to get seedlings started but no lass than 3,200 lumins to a foot. I have had problems with tomatoes and pepper plants growing too long and falling over with less lumins per foot. Hope this helps.
