I noticed that my neighbor was digging a big hole in his yard and dragging wooden boards there đČ When I saw what he built in his yard, I wanted the same đ± I’ll tell you what he did at the link in the comments đ đ
The underground greenhouse is a unique solution for growing plants all year round, even in harsh climate conditions.
Using the natural heat of the earth, this design creates a stable environment, protecting plants from sudden temperature changes and adverse weather conditions.
This is not only practical, but also economical, as it reduces heating costs.
How to choose a location for an underground greenhouse
Lighting
Place the greenhouse in a location where it will receive the maximum amount of sunlight. It is best to orient it with the south side facing the sun to make the most of natural light.
Drainage
Choose a site with good drainage. If the soil is too wet, you can provide raised beds or fill the base of the greenhouse with gravel.
Availability
Place the greenhouse so that it can be easily accessed even in winter. Consider laying out convenient paths.
Stages of construction of an underground greenhouse
1. Digging a pit
Depth: The optimal depth is 2.5-3 meters. This will allow maximum use of the earth’s heat.
Size: Standard size is 3×6 meters, but it can be varied according to your needs.
2. Walls
Use durable and long-lasting materials: brick, stone or bags of soil. It is better to insulate the northern wall with an additional layer of thermal insulation material.
3. Roof
The best roofing materials are UV-resistant plastic or polycarbonate panels. They will provide good light transmission and protection from precipitation. It is important to provide a slight slope for water drainage.
4. Gender
The best option is a gravel base that will provide good drainage. You can also use a concrete or compacted earth floor to retain natural moisture.
5. Ventilation
Be sure to include vents or windows at the top of the greenhouse. This will help control humidity and temperature, preventing overheating.
Maintenance of an underground greenhouse
Measure air temperature and humidity regularly. Use thermometers and hygrometers.
Monitor humidity levels.
Although underground greenhouses are better protected, insects and rodents can still get in. Use natural repellents and check your plants periodically for pests.
