I've decided on 33" being my final plant size plus or minus 2". I'm currently at a bushy 11". I'm thinking 15" away from hps which leads to my first question. I started with a small grow lamp. When I read literature, they always explain as if you're adding the next graduation of light as opposed to totally switching e.g. mh then add hps. Since I'm at mh should I have left the small lamp (of course adjusting for intensity) on the plant as well? Mh and hps? Or a gradual deviation from old to new lamp? Is 15" too close with a vented single end 1000W under ideal temperatures and humidity?
