This video series was developed by Kansas State Research and Extension, and includes segments on the following topics related to commercial high tunnel or hoop house production:
This University of Massachusetts website offers resources on winter vegetable crop storage, marketing and low-cost season extension through structures such as hoop houses and low tunnels.
Resources for farmers interested in on-farm winter storage options for season extension. Each resource offers a case study for a specific facility construction, and both outline important considerations for a winter storage facility.
To help farmers in the Philadelphia area learn about various winter storage options, the nonprofit Fair Food conducted site visits of well-established winter storage operations in Pennsylvania, Vermont and Quebec.Download File (1.07 MB)
