- Key Considerations
Types of Sunken Greenhouses
When it comes to underground pit greenhouses, there are several different styles to choose from. Each style offers its own unique benefits and challenges. Let’s take a closer look at the three main types of sunken greenhouses:
Chinese Style
Chinese greenhouses are an excellent option for those living in colder regions. These structures are partially sunken below ground level, with the north side buried in a hillside. They are designed to maximize heat retention and light absorption, making them ideal for cold climates.
Pit Structures
Pit structures, also known as sun-pits or earth-sheltered greenhouses, are partially sunken into the ground with translucent walls and ceilings. These structures resemble conventional greenhouses but benefit from increased heat retention due to the earth insulation.
Walipini Style
Walipini greenhouses take sunken structures to the next level by sinking them deeper into the Earth. These structures are designed to retain as much heat as possible, making them ideal for year-round cultivation. While they require more digging and construction, they offer unparalleled insulation and heat retention.
Advantages of Underground Greenhouses
One of the key advantages of underground pit greenhouses is their superior insulation properties. The Earth acts as a natural insulator, helping to retain heat and protect your plants from extreme temperatures. This insulation allows you to grow plants year-round, even in the depths of winter.
Another major advantage is the cost efficiency of these structures. Since they require fewer materials than traditional greenhouses, underground pit greenhouses can be more affordable to construct. Additionally, the increased heat retention means you may not need as much additional heating, further reducing costs.
Disadvantages
While underground pit greenhouses offer numerous benefits, they also come with some drawbacks. Water intrusion is a significant concern, particularly in areas with high moisture levels. Proper waterproofing and drainage are essential to prevent water damage and collapse of the structure.
Another potential issue is reduced light penetration, especially in extreme northern or southern latitudes. Plants located deep underground may not receive enough sunlight to thrive, so careful planning of the structure’s orientation and glazing is essential.
Key Considerations
When planning an underground pit greenhouse, there are several key considerations to keep in mind:
- Ensure proper insulation to minimize heat loss at night.
- Maximize light penetration by orienting the structure to the south (or north in the Southern Hemisphere).
- Consider building French drains and drainage ditches to manage moisture levels.
- Experiment with a variety of plant species to take advantage of the increased heat retention.
Conclusion
As you can see, underground pit greenhouses offer a unique and innovative way to extend your growing season and maximize your gardening potential. Whether you choose a Chinese style, pit structure, or Walipini design, these structures provide unparalleled insulation and heat retention.
