The Metal Halide has 2 pc's in the fixture, that I will use for the time being... I think they are 28 watts, eventually I plan on dismantelling the old fixture and combining those in with the MH fixture so I can have them run for awhile then have the MH come on later and then have it shut-off and the pc's come on for a more natural light cycle. that is after I get my new tank setup and I have a canopy to use, for now I am stuck with only fixtures that I can set on top or hang.
Does that seem like a good idea or bad?
