Information on Winter Storage
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)
Other Design Considerations
This project compared winter production using four structures: EZ Build-n-Gro Cold Frames (Farmtek); cattle panel greenhouses; modified low tunnels; and standard small cold frames.Download File (1.39 MB)
This project looked at increasing the productivity and cost effectiveness of growing more crops in a hoop house by utilizing the overhead space through innovative design.Download File (1.32 MB)
This Iowa State University video/fact sheet describes how to build a system to catch, store and reuse the rainwater for high tunnel irrigation.
