Two ballasts? You can get conversion bulbs for the ballasts. You can run a conversion HPS in a MH ballast, and vice versa. I would suggest using HPS for flowering, as the light spectrum mimics the fall sun. It'll be a flowering bonanza!!
super420 Reviewed by super420 on . 400 HPS and 400W MH Good for Flowering? I have a 400W HPS and i just got a 400W MH today. Im wondering if i used both of these lights for my sea of green. I have 8 clones that i am about to flower. They are like about 1.5-2 feet. Any thoughts? should i just get a 400W HPS Bulb? or is this a good way to go Rating: 5
