Actinics . . . Necessary??

[rickjames]

You don't need actinics. They are good for dawn/dusk though. I run a 250 10K light on my 30 with no actinics. That MH setup isn't too much light, just make sure it has good ventilation to avoid heat issues. Mine stays between 80-84F night/day with a couple of computer fans venting the canopy.
