I'm looking at some CFLs... It's an 85Watter and has 5,000 lumens... I'm growing like 2 plants so I was wondering if 2 of these lights would be a good idea? 5k x 2 = 10,000 lumens other little questions: 1. CFLs don't get as hot as HPS right? 2. Isn't It Cheaper as far as electricity bills go? 3. All I need is sockets for CFLs?
