Shoulda been a fish!
I really love this bulb but I would like to replace one of the whites with a red and perhaps a neutral white and 4500k ish to make it more full spectrum. As it is though I love the color and adjust ability of the bulb but i want to make sure I can get the most colors out of the SPS. I have kept the color close to 20k because I've always been pleased with the color of SPS from 20K metal halide bulbs. It is funny you mention the 7.5 gallon cube as that is what I'm thinking will be the successor of this spec for the grow out.
