I am so glad you all commented on my questions of indoors (under lights)
vs. greenhouse growing! Basically, you re-affirmed what I already
thought- that for the money and time involved, that I would get much
greater success with a basement grow room. Small hobby greenhouses seemd
like a fun idea, but I knew with all the variables (heat, cold, etc.)
that it would not work the way I wanted- esp. where I live.
So...I have a space that is about 4'X4' (maybe a little larger). From my
research I guess a 400 watt light would be good. Now, should it be a MH
or HPS? I know for most caes HPS is better for flowering, but is there a
particular MH or HPS better suited for orchids? Does anyone have a good
layout for a corner grow room? I figure to frame it in on the 2 sides,
and either paint it the walls white or use mylar. I will have a
circulating fan and I guess some type of shelves. Right now I have banks
of florescents (8 bulbs- cool/warm) and the orchids sit on an old,
square coffee table.
If anyone can suggest anything to help me out that would be great =)

Thanks again!
