7 tips on how to keep warm in a greenhouse in the winter and not go broke on heating

Winter greenhouse is great for growing early greens, salads or seedlings. In winter, such a greenhouse has to be heated, which is very expensive if you use electricity. However, there are ways to heat the greenhouse and save on heating.

In winter, the weather conditions are very harsh to grow fresh greens or seedlings in the beds. Therefore, many are building a winter greenhouse on the site. It is necessary to create and maintain comfortable conditions for the growth and development of plants - heat, humidity and light. In order not to splurge on the heating of the winter greenhouse and get an early harvest, follow these simple tips.

From the inside cover a greenhouse with a layer of film with air bubbles. Thanks to them, the film retains heat and blocks drafts, and the air gap formed between the greenhouse coating and the film further prevents heat loss. In addition, the air-bubble film is quite durable and well transmits light. Fasten the joints formed by covering it with adhesive tape, seal the gaps around the vent holes and the door well.

Using an air bubble film, divide the large greenhouse into smaller zones, making it a bit of a curtain. Fix the film tightly on the side of the roof and sides, and from the bottom, when it is necessary to close the fenced section, press the film down with something heavy. This separation will allow for more economical heating of the greenhouse - not all at once, but only the necessary zones.

To heat a winter greenhouse, it is best to use an electric fan and heat the greenhouse with it when the outside temperature drops below the critical limit. By pumping warm air, the fan will quickly heat up a small room and prevent freezing of tender shoots. However, this option is good if the greenhouse has a power connection. Otherwise, you can use a stand-alone paraffin heater.

The thermostat will help maintain a comfortable temperature in the greenhouse. Some modern heaters are already equipped with an integrated thermostat. It can set the desired temperature, and if it falls below, the fan heater will automatically turn on and heat the greenhouse.

Plants grown in the winter greenhouse do not require tropical conditions, so you do not need to spend energy and money to maintain a high temperature. Install a thermometer in the greenhouse and periodically check that the temperature does not fall below the threshold required for normal plant growth. And you can install a digital thermometer that will transmit the readings to the monitor of your computer. By monitoring the air temperature in the greenhouse, you can use the heater more efficiently.

On the eve of night frost, cover the beds with plants in the greenhouse with one or two layers of geotextile. This will save more heat and will not require the inclusion of a heater. In the morning, do not forget to remove the covering material so that the plants do not get stuck.

Instead of heating the entire greenhouse, which is quite expensive, try to germinate the seeds in the propagator. Invest in a good electric heated mini-greenhouse to germinate demanding to a comfortable temperature seeds. And when the seedlings get stronger, land it in a greenhouse insulated with air-bubble wrap, reasonably heat it and cover it with geotextile for the night.

If you decide to put a winter greenhouse on the plot, do it! And do not worry about heating, because there are ways to do it economically.

And one more important point. In the autumn and winter light day is very short. So that your greenhouse crops can develop normally and enjoy a good harvest, take care of lighting in advance.
