It's not a glasshouse, and it certainly wouldn't look great in a living room, but it does do the trick in my garage! I winter many of my cp's here (and more show up 2-3 times a winter when a freeze is expected). I keep some here through the summer, although I shut down most of the shelves as the heat gets too high.
They seem to be doing OK in here with no heat andno added humidity. Many are starting to flower:
Here is my little window terrarium - it only holds up to 6 2" pots, but as the light levels are pretty low and the grow rack is full, I keep 2 juveniles here now.
