Morgan you are a lil' off the mark on your prices. I can get a 6 bulb system for $300.00 and the bulbs are less than $20.00 each. Also, I do believe they have a longer life span so only need to be changed every 12-18 months, as apposed to every 8-12 months for MH or PC. I do realize that a T5 fixture would run me about the same price as a MH fixture. But with a MH fixture, I'd still have to add something for actinics. To get a fixture that's a combination MH and PC or MH and T5 or MH and anything at all that offers actinics would be WAY more expensive. Then if I go MH, I'm still having to worry about a heat issue. I've already battled that last summer with only PC lighting running. If I were to go with MH, I'd either need to get a 48" fixture, which would run me about $700 or more....or I'd have to go with at least 2 pendants and still have to supplement with some kind of flourescents for actinic. However, I do understand part of what you're saying and I do realize that MH have advantages that T5 don't have and I really would like the glitter effect of MH but just can't afford the amount of MH lighting I'd need, nor can I figure out a way to combat the heating issue without added expense.
