High Tunnel Winter Growing Using Heat Recovery Ventilation
A posting from Michigan State University Extension discusses the difference between winter production and overwintered cold-season hoop-house crops. Winter crops are intended to reach maturity as growth rates decline with shorter hours of daylight. In Michigan, using a hoop house can extend the harvest season for tender crops into mid-December, and the season for hardy crops can extend into February. By contrast, overwintered crops are planted late in the fall and not harvested until growth rates increase in the spring. Both strategies can help growers bring crops to market outside the customary growing season, contributing to customer retention and increased revenue. Which option a grower chooses will depend on the crop and production system.
