I know I saw that, they are very expensive. Where did you get your 10.0 cfl? I am not sure those flood lights would work. And how about the MV bulb. MV usually gets pretty hot. I imagine this MV UVB Bulb would get pretty hot too. Have you grown a crop without the UVB and a crop with the UVB bulb? Do you notice a difference in trich developement with or without the UVB Bulbs?
