I have 2X250W MH's right now , running bulbs that are just not blue enough to make the corals "pop". So I want some supplementation but I don't need any extra heat. Is LED best for this application, or should I just go with T5? Also, space is at a premium as the reflectors for the MHs pretty much take up my entire canopy (so t5s are not really all that great a solution due to the size of the reflectors). So anyway, should or can I use LEDs for actinic supplementation and if so, which fixture should I buy or should I just DIY (this doesn't scare me, btw)?
