The test was run using 250,400 and 600 w lights. Mh and hps. There was no difference with yield until we checked the 600 and the buds were heavier and denser using the hps.
So then with the 1000 watts it would more then likely make a difference wouldn't you think?
I'll switch to hps for flower,
but when would I do that?
Once pre-flowers show?
