No. I use CFL's, and i have 12 of the 23 watt, 2 125 watt, and 4 4ft florescent shop lights on back wall. Area is 2ftx4ftx4ft high. While I have enough light to grow some nice plants with dense buds, I believe a good 600 watt grow light would work better. I could have bought a grow light for what it would have cost to buy all my lights, but I had most everything. Heat is an issue for me as that many lights put out a lot of heat, and an air cooled light would be an easier fix than the 9 120 mm fans i have currently running. I believe you have to have lights mounted low to make up for lack of light penetration and that is where back wall lights come into play. Oh, and I only grow 2 plants at a time. Average yields vary from 1 to 1.5 ounces a plant if I do 12/12 from seed with little or no lst, to 2.5 to 4 ounces depending on the amount of veg, and how much lst, or topping I do, with about 2.5 to 3 being more common yields. Hope there is some info here that is useful, as I just sampled a bud of chocolate heaven I have curing. Taste isn't quite there yet, but boy, can she kick you in the brain.
