The 13th winter for the greenhouse. So far, so good. 10°F last night. After a few sunny days, the solar collector loop had the water in the heatsink up to 94° and the floor up to 58°. When there's no sun, I leave the snow on the roof as insulation.
Thinned out the indeterminate tomatoes to let in more light. They don't produce as well in the dark of the year, but there's always a few ripe tomatoes to be had. The greens in the center bed sprouted nicely and are looking good.
We're eating the Bibb lettuce. The thick patch is radishes, arugula and spinach, ready to thin for sprouts. Also bush beans and lettuce seedlings.
The heirloom Moskvich tomatoes do well in cool conditions. Night temps inside stay in the 40-50° range, with ceiling-mounted quartz radiants and a small electric heater to supplement the retained heat of the floor.
Another heirloom, a Roma-type called Peasant, goes on producing through the cold months.
