Product Description

A Macrotunnel is a simple structure that allows coverage of a large area to grow crops in a controlled and protected environment. A macrotunnel has a medium height and can cover several rows of plants. It is smaller than a greenhouse and is used when excessive control of the conditions inside is not required. The use of macrotunnels is becoming important for the production of fresh-market produce since it minimizes the risk of frost and results in increased early production, total productivity and fruit quality.
