SilentGuy Posted July 30, 2013 Report Share Posted July 30, 2013 Has anyone tried this blue bulb when plants start to bud, and only this bulb. I'm wondering whether a red bulb is really necessary, or whether it's just for optimal development whether it is minor or major gains. Also reversely, how well does a growing (non-budding) plant perform in a red bulb only environment. Quote Link to comment Share on other sites More sharing options...
