i agree cfls are very effective. but the only problem i have had with them is that on all three grows iv done with them my plants start very small and stay small until about two weeks into flowering then out of no where they explode and almost quadruple in size. and iv used different seeds, soil, water, ferts., different cfls, and watering schedule, and no change on any of the grows. plus iv never seen this with any other grow iv seen. i mean on of my plants is 33 days from seed and its starting its tenth internod and its only about 5.5-6 in tall. but other than that there great for a small stealth grow and the quality of the final product is some of the best iv ever had.
