If you already have the UFO light you are more than just "thinking about growing." You may want to read the threads in Hydroponics. You most likely will find the Hydro people in there.

To dig up threads on this, look under the header under 1999, there is a search box and cannagoogle your topic. See what you may find. Lots of threads here on growing.

Oh, and Welcome to the site! Happy growing from here ever-after! pr
