Have you looked at these two LED manufactures ? Grand Master LED Tarantula Borg - 1500watt 4 channel full spectrum, I have one, it's incredible. The next best thing on the market is a DIMLUX Xtreme either 1,000 watt, 750 watt, or 500 watt - it has a nice feature of having doppler radar and a plant camera that will sense the leaf transpiration rate and adjust the spectrum output accordingly

.
Or go buy some cheap lights and let it be a hobby not scientific

~ akin to organic as to synthetics , don't panic it's organic? roots = shoots = flowers = fruits

thus your search for LED's is over now enjoy your growing!
