Many gardeners begin planting cold-resistant crops in permanent greenhouses in early spring, when frosts are not the exception but the rule.
In some cases, you even have to think about heating the greenhouse. The industry offers effective but expensive means.
Heating a greenhouse using home-made methods is also not difficult. Here is how experienced gardeners solve this issue.
How to build heating for a greenhouse
A heating device that does not depend on electricity can be made from an old metal bucket with a lid, a tin can (from canned food or paint), sunflower oil and a candle (paraffin or other). You will also need some alabaster, gypsum or other dry building mixture.
1. Take a tin can, place a candle inside and fill it with diluted alabaster or gypsum from the base by 1-2 cm to fix it.
2. When the mixture sets and the candle stands tightly in the jar, pour sunflower oil into the jar.
3. Make several holes in the bucket at the bottom and top for ventilation. Place a jar with a candle inside, light it and cover with a lid.
During combustion, the temperature, if measured on the lid of the bucket, will rise to 70 degrees Celsius. Given the volume of the greenhouse, you can make several of these heaters and successfully heat the room in the off-season.
