So far I am having great results with the flouros I am using. I started with standard Sylvania 24 watt compact flouros for the first 2 weeks of vegging. Then I switched to 42 watt full spectrum Ozonelites. They are so much brighter that they make the original CFs look like standard house lightbulbs. They plants responded immediately and I am one week into flowering with these beautiful White Widows so far. My friend can hardly contain himself(his realestate, my garden). No problems so far.
