In my opinion I don't think I would run the hydroponic lights as they don't have an acrylic shield or glass covering the bulbs, I would be far too worried about water splashing. Unless if course you can rig up a cover for the bulbs.
I heard the mh
were fixed as well, at least as far as catching fire. lol there's still been some members who have had issues with them and some who just love them. But only time will tell for sure. I wouldn't cross them off your list though completely, it might still be an option. If only they made a 6 bulb unit lol.....cause thats what I would put over it if I could.
