Yeah totally. The fluorescent grow uses a little less of everything but I have larger plants under the hps. But really considering their is not a big difference in plant consumption at least now that its cooled off. In the summer months my hps garden will consume up to 10 gal. a day.
I am trying to find a suitable strain for my fluorescent grow as I need short plants because the light does not penetrate much over a foot away. Do you know any single cola short strains that are stable?
