What he said.
Been doing your reading Cassius. No envirolights here yet, not even flourex. I've found two non-hydro outlets for HPS. You still have to mess with the ballasts to make them remote.
Also, what you pay a dollar for, usually costs us a quid or more, but then, they don't jail us for a few dozen plants.
It's difficult to believe how easy this hobby is at first, so I always recommend strip lights for first grow. When the plants get to 24" the grower normally buys an HPS, and the strip lights are still useful.
