I started with orchids in Nov 05 - an impulse buy of two oncidium-type intergenerics on my way out of Home Depot. Got home, started Googling orchids - collection grows fast. First winter I kept them on some cheap shelves in the dining room. Next winter, they need their own room - they move into an unused room that became a grow room with CFLs all over the place. Room get remodeled - plants move into the office at work for the next winter along with the CFLs (don't ever do this...). Last winter I tried building a temporary PVC structure that I could attach 6 mil film onto for the patio - that didn't go very well, so as winter descended I bought this small hexagonal temporary greenhouse (about 5' per side and 8' tall in the center) by Sonnenhaus and put it on the patio - it has vents on the roof that can keep temps down on warm days. The benches I normally use on the patio barely fit, so the space was used very inefficiently. Stuff was hanging from wires all over the place. This year I built some simple 3 ' wide benches that fit around the edge of the hexagon and layered some bubblewrap over the whole thing to try to keep heating costs down. I use the little electric heater you can see in the fourth pic, just on cold nights to keep things above 40F. I can stand upright in the middle and reach every plant. A real greenhouse sure would be nice, but alas, is at least a few years off.
