Has anybody used the tubing benders from
Lost Creek Greenhouse Systems, or built a greenhouse of this type? I'm thinking about an inexpensive way to build a greenhouse for this winter. While it normally doesn't get that cold here for long periods of time, according to
NOAA, San Antonio has averaged 21 days/year below freezing over a 60 year period, and I have seen it in the teens near here in the past 6-7 years. Anyway, I'll need a place for my ficus this winter, and it'd be a nice place to get some other things started that my wife would like (there, I've justified it

). This looks like it might be a good way to go.
Thoughts?
