I'm planning a new light system for a SPS tank. I decided to do 400W Radiums on the MH and am torn between VHO or T5 supplements.
All the systems that I admire use VHO actinic, part of me belies it's due to them being mature and established before T5 was popular.
What are the benefits of VHO over T5 in a SPS system if PAR is not a issue ?
