I have an oddyssea dual 250w double mh/ 4 54w t5ho that has the original bulbs in it. They come with 10k 250w mh and 4 actinic t5. I would like to replace the t5 bulbs. Any suggestions? I have some sps, lps, and softies. Would like best combo for growth and color. I have also read that the ballasts that come with this fixture don't burn the high end mh bulbs at the right spectrum. Isthis correct? What mh bulbs should I get?
