PortFish Extended Growing Season Project

As of October 2013 PortFish, Ltd. finished construction of 20 of the 30 cold frames we plan to build outside of our aquaponics facility in Port Washington, Wisconsin. Not everyone can build a 4,400 square foot greenhouse and fish habitat, but we think a large number of people can become familiar with the concept of extended growing seasons using cold frames. Providing a learning opportunity and access to raising vegetables beyond the traditional growing season is our goal.

There are several groups in Port Washington that stand to benefit from learning more about gardening, especially when it means extending the traditional 5 to 6-month growing season to 9 to 10 months. Using an appropriately designed and constructed cold frame, plants like spinach, kale, bok choy, Swiss chard and arugula (cold loving greens) can be grown and harvested up to the end of December and revived again in March for continued harvesting into the summer months. 

PortFish will provide access to these cold frames to individuals who are already participating in conventional gardening with the Hales Trail Community Garden, and to persons either receiving from, or volunteering for the Port Washington Food Pantry, and the Saukville Food Pantry. Included in the process would be a two-hour workshop introduction to Extended Growing Seasons, and a two-hour follow-up workshop.

The project would include showing the participants the design and construction of a cold frame. We also intend to design and build a water collection and distribution system for these cold frames during the course of this ten-month project.
