Hi Susan and All,
HID lights for indoor growers have opened a whole new world of growing.  I
used to only grow under fluorescents, and small plants because the efficacy
of the light diminishes radically after about 2 feet
i was somehow able to grow Haworthias and other succulents of South Africa by placing them two inches from the fluorescents, but it did not make for good display, just for great plants!

there are other colour corrected mercury vapour and incandescent lights combined in one---- and every month, new kinds of agricultural lights appear in the commercial catalogues.but it is true to grow larger plants which need lots of light, fluorescents, unless they are in banks, about 1/2 inch apart, as in a growth chamber, do not do it. i grew Cycads under artificial light at one time. but not under fluorescents.

and these lights are also used in Alaskan greenhouses to prolong day length for things like tomatoes, so not everyone who buys them is a drug fiend. the ballasts give off heat, which is also a plus in Alaska.

I would think modern drug fiends are taking CHEMICAL DRUGS and not stuff like boo! (pot, in brooklyn, circa 1965).
