SD79: Environmental conditions in temperate high tunnel systems

High tunnels are an important agricultural tool that allows for extenstion of the growing season. Because of the insulated nature of the high tunnels, temperature and humidity will differ inside compared to the surrounding enviroment. We analyzed abiotic factors recorded in 34 high tunnels over 4 years. We found that the high tunnels have greater GDD's, especially in shoulder and cold seasons. High tunnels also have a large range of temperature fluctuations. The temperature - insect dynamics will depend of infividual species phsyiology.
