What are pit greenhouses?
Pit greenhouses are a type of underground greenhouse design which uses large pits dug into the ground or other suitable surface materials such as rocks, gravel, sand etc. These large holes are filled with soil or other material and covered with a layer of dirt or leaves. A small hole is then cut through one side of the pit and used to access the air inside. The air from outside is forced into the pit and out through the small opening. This method allows plants to grow without any sunlight, but it does not provide enough light for most plants.
The advantage of using a pit greenhouse over other types of greenhouses is that it provides adequate lighting for many different kinds of plants. However, there are disadvantages too. There is no ventilation system so the air inside the greenhouse must be constantly circulated. Also, the temperature inside the greenhouse may drop due to lack of circulation.
Plants grown in a pit greenhouse will need constant watering. Watering plants requires frequent draining of water from the bottom of the pit and pumping it up through pipes to allow for proper drainage.
How do I build my own pit greenhouse?
There are several ways to construct your own pit greenhouses. You must first decide the size and shape of your pit greenhouse. You could make it in the shape of a circle or a square, or you could even make it in the shape of a pyramid. Make sure that there is at least an inch of space between the top of the pit and the surface to allow for proper ventilation.
Fill up your pit with soil and begin planting your seeds or cuttings. You will need some way to keep the pit from getting too hot or too cold, so you will also need to water your plants on a weekly basis. You can place a small fan at the top of your pit to circulate the air inside. Be sure to keep it running as much as possible.
Pit Greenhouse Designs
Pit greenhouses can be made several different ways. They can also have several different shapes and designs. You can make a pit greenhouse from a single long, narrow hole in the ground. You can also make it in the shape of a square or a circle.
A pit greenhouse can even be made in the shape of a pyramid. This shape is very popular among gardeners because it helps to keep the plants inside protected from wind and weather damage.
Many gardeners like the idea of building a pit greenhouse because it is very easy to construct. You can build it yourself in just a few hours. Greenhouse plan books are also easy to come by and there are many different kinds available to fit your needs and your budget. Before you begin construction, be sure to let your local building department know what you intend to do.
They will be able to give you advice and tips on how to proceed.
Advantages of Pit Greenhouses
Pit greenhouses can be very beneficial to the avid gardener who wants to extend their growing season. They can be used in areas that don’t get a lot of sunlight or in areas that are prone to extreme cold. The best thing about pit greenhouses is that they are very easy to build, affordable and require little maintenance.
Another advantage of pit greenhouses is that they can easily be turned into root cellars. A root cellar is an area of the house that is kept cool and used for storing vegetables and fruits. Many people like to have one because it allows them to keep their foods fresh longer.
Disadvantages of Pit Greenhouses
One major disadvantage of pit greenhouses is that they require a great deal of maintenance. Each pit greenhouse will need to have its soil replaced each year and some types need to be painted to protect the wood from moisture damage or else they may develop mold.
Another disadvantage is that pit greenhouses may not be very large. If you want to grow big vegetables, such as pumpkins, you may need to use a different kind of greenhouse that is more expensive to build and maintain.
Pit greenhouses can also be less energy efficient than other types of greenhouses. Because they are underground, the natural temperature around them tends to stay around 50 degrees all of the time. This means that you will need to use a heater or an air conditioner in order to keep your plants from getting too cold or too hot.
Last but not least, pit greenhouses tend to have very poor ventilation. This can cause the greenhouse to develop a strong odor over time. You may want to be prepared to deal with this issue.
