Macrotunnels for controlled environments.

The technology consists of the construction of small structures (5 m wide by 16 m long) in the form of tunnels that serve to protect crops, especially vegetables. In its manufacture, iron rods are used, which form an arch when embedded in the floor, supported by posts with round sticks and attached to galvanized wires to which a plastic cover is tied to protect against ultraviolet rays. The main objective of the macrotunnels is to control excess precipitation that affects the cultivation of vegetables, which causes their total loss or reduces their quality due to a decrease in size, color or the splash of fungi on the leaves, which cause rot and mistreatment of foliage. Also, it reduces evapotranspiration levels by reducing the direct influence of the sun on crops, which optimizes water management in a controlled environment. In addition to protecting crops from excess rainfall, macrotunnels offer protection against changes in temperature, pests and other threats.
