PS the 3200 K one you see will help force flower but its not good for mothers over years. Better then a 2100 hps but not great. Thats just me
karmaxul Reviewed by karmaxul on . LIGHTING QUESTIONS I've got this 1kw MH ballast that I've been running for a few years now with a single, 400w MH bulb.

The 400w is the standard "blue spectrum" kind that's discussed here a lot. I think I'd like to add some red spectrum for flowering. I've been reading this forum about mercury Rating: 5
