Retractable roofs protect crops against excessive heat, cold, frost, hail, wind, diseases and pests. The roof creates an environment with a constant temperature and humidity level, making it possible for a farmer to extend the growing season,and increase profitability/ha. According to Richard Vollebregt, president of Cravo Equipment, a Canadian company that manufacturers retractable greenhouse roofs and production systems, retractable roof technology has been adopted in the US, Mexico, Chile, Nigeria and South Africa. "Annually, South Africa experiences 5 658 hours (65%)of ideal outdoor growing conditions," Vollebregt said. This means that farmers lose out on 3 012 (35%) potential growing hours each year, which could be used to increase production.
