So after 8 years away I picked up a 60 cube and diving back in. There are a few more lighting options than when I left. Going to be sps dominant with some Lps. I have been looking at the AI hydra 26 as an option. Is one of these over a 24x24x24 cube enough for sps ? Should I do two ? Should I just go old school and put a 250watt halide over it ? Not really wanting to dish out the coin on the radians. What would be a good cost effective setup if you were an sps junkie ?
