What is a greenhouse tunnel?

greenhouse tunnels are a type of greenhouse. It is known under various names, but all consist of a metal frame with a plastic exterior used to extend the vegetation season of the crop. Greenhouse tunnels come in two sizes, a low tunnel and a high tunnel, yet they look the same and work in the same way. .

Cold Frame, Hoop House and the French tunnel are all alternative names for the greenhouse tunnel, but regardless of the title that are usually designed in the same way. They are shaped as a half cylinder and are made of an open metal frame, which is covered with clean plastic. This frame is then placed on plants or crops that need additional heat or protection.

There are two different types of greenhouse hoops, high hoop and low hoop. Both are designed in almost the same way, but the low hoop is close to the ground, often not growing above 2 to 3 feet (0.6 to 0.9 meters). High hoops are at least sufficiently large for the individual to stand up andThey are able to grow high crops.

greenhouse tunnels work because their clean plastic outer traps in sunlight and maintain its interior warmer than outdoor temperature. They are also able to protect plants from mild freezing and high winds or heavy rains. In the hot climate, the plastic exterior can be downloaded back to vent the space, and if the strong sun rays threaten to grab the plants, the plastic cover can be replaced by a fabric cover that provides shade.

Because of these advantages, the greenhouse tunnel is able to significantly extend the vegetation period of many crops. The seeds can be planted outside in the tunnel when it is still too cold to plant them outside. Crops can survive in the greenhouse tunnel for longer until the end of the season than they did outside as soon as the weather was colder.

crops of grown greenhouse can move the tunnel from fruit and fromLeniny after flowers. Plants in the tunnel are usually planted directly into the ground as if they were planted in the garden or field, rather than in pots or containers. Plants grown in the tunnel must be regularly irrigated because rainwater does not penetrate the exterior.

There are also a number of disadvantages for greenhouse tunnels. Many high tunnels are immobile or very difficult to move. This means that there is a limited opportunity for crops to rotate or to lay the ground if the gardener or farmer does not own a series of greenhouse tunnels. Lack of plant rotation increases the chance of developing the disease in the soil and also increases the risk that the soil under the tunnel is exhausted. Because the coverage is made of plastic, the tunnels can be damaged by strong wind.
