that is still WIDLEY debated. those who have MH believe so, those who have t5, believe differently. I have seen all kept under MH and have heard many many stories, however, they must be relativly close to the surface, and you must have a quality t5 fixture. you will find that you get what you pay for. an 8 bulb Nova fixture will not even be able to compete with an icecap. plus, if you use the ice cap VHO ballasts, you can overdrive your bulbs, it greatly decreases the life, but instead of 24 watts, you will have close to 50 per bulb.
PS: if you want anythign higher light, i would also go with 6-8 bulbs, not 4 from what i have researched.
