Thanks CPW! When I was growing with CFLs I had 4 or 5 at different places to try to cover as much of the plant as I could. One CFL is going to be tough to grow one much less 3 plants successfully. I really think if you can buy a inexpensive led from Amazon. For the amount you smoke you will get the light will pay for itself in one grow. You can pick one up for under 75 bucks.
