I live in the northeast USA, and have a nice collection of Orchids. Lots
of Phals, a Paph, couple Cymbidiums, Dens, and Onc's...
I have a great bow window in my living room that gets western sun. The
phals in particular do GREAT there. Some bloom for 6- 8 months...
When they are done flowering I put them in my basement under banks of
cool/warm forescents. Again, the Phals seem to do great and spike each
year- the others don't flower and I assuming it is due to lack of light.
Now with spring coming I am thinking of getting a small hobby
greenhouse. I have been looking at the Julliana Polycarb green houses
(http://www.littlegreenhouse.com/basic.shtml) that I could put in my
backyard. I probably would not want to heat it in winter- so the plants
would have to come inside for a few months.
My question is this- would I be better off buying a HPS or MH light and
expanding a basement grow room? I think a greenhouse would be much more
fun, but if I dont get a commercial type (with heat, auto vents, etc)
will I have much success with it? Ideally I would like to purchace small
plants from a local greenhouse grower and develope them into plants I
can display in my livingroom window when in bloom.
