When there is snow and frost outside the window, it is nice to do four season growing in a greenhouse, taking care of plants, prolonging the season of fresh vegetables and fruits. Here you can grow greens, flowers, and even berries.
For four season growing of any plants in greenhouse, the structure itself must be solid with a good foundation. The coating can be polycarbonate or glass. Film or non-woven fabrics are not suitable for year-round greenhouse cultivation. They are very fragile and short lived. Such heaters are used as additional components.
