Sounds like a killer setup. I don't know anything about cmh lighting but they seem to be very effective and nearly as efficient as COB LEDs. I checked out the site you listed and couldn't find any citizen leds listed. I've narrowed it down to either the Go Green led (citizen) or a Timber led kit (citizens or cxb3590) for a small 1.5x2.5thanks,, just ordered 2 of the 100 watt citizen 2 cobs.. i ordered through flora hydroponics and saved a hundred bucks,, $350.00 with shipping for 2, at gogreen it was 448.00.... anyways i cant wait to try these things, ill be running the 2 citizens along with 2 315watt cmh lights, the 315's are 3100k and the citizens are 4000k so it should be a very balanced spectrum.. any thoughts?
