What Is A Tunnel Greenhouse?

A tunnel greenhouse is typically a steel structure and polyethylene cover. High tunnel greenhouses are usually semi-circular or square. The interior of tunnel greenhouses heats up from the sun and warms the soil and plants inside the greenhouse. The polyethylene covering then retains the air warmed by the heat.

You can then control the temperature and humidity by fixing equipment into the tunnel greenhouse or manually opening and closing vents. The tunnel provides higher temperatures and humidity than what is available in the environment.

Tunnel greenhouses also protect the plants from bright sunlight, intense heat, cold waves, hailstorms, and wind. This protection will allow you to grow plants during any season. Fruits, vegetables, and herbs are among the best plants to grow in tunnel greenhouses. If you are growing plants that do not need much space, then you can consider low tunnel greenhouses. 

Low tunnel greenhouses are mini-greenhouses. They provide a temperate micro-growing climate by warming the soil. If you are growing in your backyard, where space is limited, a high tunnel greenhouse might not be practical. In this case, it would be best to consider installing a high tunnel hoop house. A PVC hoop house is smaller in size and maximizes simplicity while maintaining the benefits of a tunnel greenhouse.

Why Have A Tunnel Greenhouse At Home?

Greenhouse farming has many benefits compared to conventional agriculture. The following are the benefits of tunnel greenhouses.

Extended Growing Season

Tunnel greenhouses allow growers to produce crops for longer periods during the year. The greenhouse will protect the plants from extreme temperatures.

Lower Price

Tunnel greenhouses are cheaper compared to window greenhouses. Despite the reasonable price, tunnel greenhouses are still dependable and robust. The price offers a quick and high return on investment.

Easy To Assemble And Disassemble

You will only require a few tools to assemble and disassemble tunnel greenhouses. It is hence easy to relocate a tunnel greenhouse. You only need to unbolt the rafters, remove the cover, and move your greenhouse to a new location. Once in the new site, install the ground posts, bolt the rafters, and put back the covering.

Easy To Expand

If space is not a challenge, you can quickly and easily expand your tunnel greenhouse lengthwise. 

Increased Yields

Tunnel greenhouses create an ideal environment for your plants to grow. Plants yield more when they grow in their optimal conditions. The tunnel will provide more control over inputs such as temperature, water, humidity, and fertilizer.

Deters Pests And Diseases

The controlled environment in tunnel greenhouses reduces the occurrence of pests and insects. The atmosphere is also less hospitable to diseases. Growers can reduce the cost of pesticides and chemicals.

Use Of Farm Machinery

High tunnel greenhouses accommodate one specific need: the ability to use farm machinery. High tunnels are often taller than a standard greenhouse.  Growers are therefore able to bring in tractors and other farm machinery directly into the growing space.
