Pre-installed exhaust fan to get rid of help from excessive moisture.

The number and power of infrared heaters depends not only on the area of ​​the polycarbonate greenhouse, but also on the height of their location, the desired air temperature.

Water heating

The principle of its work as a home heating. The movement of hot water is carried out through the pipe, so the earth warms up. You can hold it from home or install a separate boiler. Pipes should be located around the perimeter. heated greenhouse and between the beds.

If a stove is installed, then it can be stoked cheaply. For this fit any garbage from the garden plot.

Inside polycarbonate greenhouse can be covered with another layer of film with air bubbles. The layer of air formed between the film and polycarbonate, significantly reduces heat loss. If according to the weather forecast frosts are foreseen, then instead of heating, beds can be covered with geotextiles. So you can keep warm, but in the morning you need to remove the material, otherwise the seedlings will rot.
