I have used the colored lights you are talking about. I tried the blue ones for veg. I was using three blue bulbs and 1 white cfl. The plant was very short, and obviously wasn't getting enough light. The blue cfl's were 23w, while the white was 43w. The colored bulbs aren't as bright,(even compared to a 23w white cfl.) and produce more heat. I found negative results, maybe i just needed more blue CFL's, but why go that route when white CFl's work better.
casual Reviewed by casual on . CFL LIGHT QUESTION All right here is a question, when growing with cfl's would using coloured cfl mixed in with the rest of them aid or hinder the growth. Blue for veg and red for budding. i thought it might be a interesting topic, if anyone has done it let us know what were your results. Rating: 5
