Managing the Environment in High Tunnels for Cool Season Vegetable Production

Light, temperature, and relative humidity influence how crops grow and develop. With support from SARE, Purdue University Extension developed this publication, which introduces important factors to consider during design, operation, and daily management of high tunnels, and explains plant responses to the environment.Download File (1.16 MB)
