Butlerville, Winter, 2003

Initial plantings were made at SEPAC in mid October. Cold houses were placed over the planted beds. Both structures are filled with sequential plantings of cold hardy species. See appendix C for planting diagrams.

SEPAC DEMONSTRATION

Summer 2003

The two mobile cold houses have been moved to their summer locations. Shade cloth will replace the plastic. The plastic on the ends has been removed to provide ventilation. Next season the design will be adjusted so the lower 3' of side plastic can be raised for better cross ventilation.

Note metal braced solid corners. Rows of cement blocks allow the frame to be slid from over a growing crop to the next location.

Black and silver plastic mulches are compared on a variety of crop species.
