From what I have seen on other grows, these lights are not so effective on all stages . I'm 3 weeks into flowering and I'm not getting too much buds. Its been more than a learning experience . I have far biggeer plans for my new grow . I'm going DWC / bubbleponics . Doing cfl for light untill I save up for HPS. I will update april 11th . The day I chop down . I don't plan on makimg over
5 grams. Plants are 19 inches tall. Feed nothing but bottled water, this was my test grow . So my second grow should be more serious and on a bit bigger scale lol
