PharmaCan Reviewed by PharmaCan on . Which Fluorescents Do I need to Flower? Im doing a Box Of Green grow and I have 2 20 watt 24" florescent bulbs; one Warm White and one Cool White. When I start to flower the clones that I put in there, after they've gotten closer towards the screen, I plan on throwin' in some more light. Which CFL bulbs am I gonna wanna be looking for on the package to mimic an HPS's light spectrum? I'm gonna leave the 24'' bulbs in there as well. Any help would be appreciated! -CS Rating: 5
