For beginners or those with limited space, a small greenhouse (6×8 ft) is ideal for growing herbs and starting seedlings.

For a family of two a family of two can typically sustain themselves with a greenhouse measuring approximately 10×10 feet (100 square feet).

Can plants survive in an unheated greenhouse?
It’s definitely possible to grow without heat if you use cold frames and/or hoop tunnels inside the greenhouse. In my climate, venting the heat on sunny days would be essential, even on cold days. An unheated greenhouse stays 5-8C warmer than outside at night and 15-20C warmer on sunny winter days. That is enough to keep hardy salads growing through every month of the year. Lamb’s lettuce, claytonia, land cress, and mizuna all survive to -15C under glass.On a still, cold night, an unheated greenhouse typically stays 2-5C warmer than outside. On windy nights, that margin shrinks because moving air strips heat from the glass faster. By dawn, the temperature inside an unheated, uninsulated greenhouse can be only 1-2C above the outside air.
