Thanks GPS,
Even what you have stated is a good start to answering some of the questions that are out there with out having to weed through multiple sources.
I totally understand in some instances it is comparing apple to oranges, some
lights give off heat and need fans others are cooler but not as intense, etc.
But again those are things that people have to mull through a lot of info to gather and having them in one place is helpful.
Unfortunately, growing year round in natural light is not an option for me. I live in Wisconsin and the amount of light wanes in the winter not to mention I am gong to try this Aquaponically and have yet to develope a taste for fish popsicles.
