Dwill: I think it depends a lot on what scale you're intending to grow on. I'm strictly a personal grower, less than six plants for my meds and I'm in no hurry. I use T-5 fluorescent lighting from seed sprouting through harvest and it's worked well for me. They burn cool and cheap and frankly that's good enough for me. If you're considering CFL's you might want to take a look at SeeMoreBuds' book, "MARIJUANA BUDS FOR LESS- GROW 8 0Z FOR LESS THAN $100." He illustrates his grow with only CFL's and it's pretty impressive. If you decide to try T-5's just make sure you get a fixture big enough to completely cover your grow. If you do I'm sure you won't be disappointed. I hope that helps. HSA
