good info ben. much apretiated. I like how you kept it real here and didnt ripp on other people`s setups.... here it is....
It really doesn't matter what you use as long as you're growing plenty of foliage and keeping it green, healthy, and abundant until harvest. Some of my best results were using a HPS ONLY from start to finish. There is alot of hype when it comes to light spectrums. I have found in spite of all the ditties on spectrums, professional and otherwise, that the plant just doesn't care. Do the experiment. Grow a garden with only a HPS or MH, see for yourself. They are both full spectrum plants. The manufacturers and their vendors are only in it for the money, so they'll push this and that, conversion ballasts, all kinds of crap, etc. My best and most efficient hood is an old Diamond Lights, SMALL horizontal hood with a gull wing insert which I retrofitted with some very high quality, super shiny, spectral material using a drill and a rivet gun. I also built my own ballast box using parts and a junction box to house them in.
