On the Internet, it is often recommended to open the greenhouse for the winter to freeze the soil.
However, experts say there is no need for this.
We explain why there is no point in keeping the greenhouse open in winter.
With the onset of winter, the difference in temperatures between open and closed ground practically disappears.
It turns out that it is not at all necessary to open the greenhouse to freeze the soil.
You also need to consider the region. If your winter is cold and long, the ground in the greenhouse will freeze anyway.
If the winter is warm, the soil is unlikely to freeze even if the greenhouse is constantly open.
At the same time, periodic ventilation is necessary. This is especially true for completely sealed greenhouses.
For reference
A greenhouse is a heated or autonomous hothouse for year-round or off-season cultivation of greenhouse crops and seedlings.
