I'm five days into flowering on my god's gift clone, I'm thinking about switching my lighting from 1 42w cfl and 2 75w grow lamps to 2 red 13w cfls and one black 13w cfl. First, i'm wondering if thats enough(2550 lumens). and if black and red cfl's can flower a plant. I know blacklights are useless but I was wondering if a black cfl is okay.
Also, yellow or green cfls?
