Do you think I would be ok just putting a 600w metal halide up high just to give it that extra boos of light, or will the metal halide have a negative affect on the crop, and thaks for the advice!
mr samsung Reviewed by mr samsung on . Is it better to use Metal halide as well as hps lights in flower I an currently 4 weeks into flower, I have four Plants under one 600w hps. They seem to be growing to big and I only have a 600w mh left. Could I use mh as well as hps in flower, would it stop them growing in hight as they are getting a little tall. And what effects would the mh bulb have on the yield and density of the crop. Rating: 5
