My Susan has the same one in green.
We had tomatoes well into the winter.
Heated with a 3000w 220v fan forced heater in winter.
Temp controlled in warmer weather by thermally actuated roof panel.
She grows all sorts of vegetables, flowers and whatnot.
Susan has certificates from the NY Botanical Gardens in a few different areas.
Damn tomato plants have stems almost an inch thick.
I am the only Italian that cannot grow stuff. So, the canning, plumbing and other non-dirty (I know it is called soil!) stuff is my job.
On the list of things to do are; Rainwater management system, Drip irrigation expansion, etc.
Suzy likes it, and that is all that matters.
