As a horticultural farmer, your crop is your life and you will do anything to protect it and ensure that it flourishes to its fullest potential. One way to ensure you have a healthy crop is to install a tunnel greenhouse. In this article, we will discuss everything you need to know about greenhouse tunnels.
Tunnel farming aims to protect one's crops from environmental hazards. This is done by creating an elongated tunnel-like structure that is either semi-circular or square-shaped. The structure is typically built out of steel pipes over which a polyethene plastic is secured. This will generally protect the plants from elements such as hail, strong winds, extreme sunny conditions, snow, frosts andpests. Both subsistence and commercial farmers make use of tunnels; however, commercial farmers will typically also employ greenhouse methods such as electric lighting and ventilation. Tunnel farming is well known for its ability to grow crops that require warm weather in areas or times of the year where temperatures are below ideal.
The Benefits of Greenhouse Tunnels
There are multiple benefits to making use of greenhouse tunnels that make them an appealing option to farmers. The most noticeable advantages consist of:
