Completed in December 2011, the passive greenhouse allows year-round fresh vegetable production. In the winter, we grow cold-hardy crops like collards, spinach, salad greens, and radishes without electricity. Openers respond to the change in temperature to open the vents if the greenhouse gets too warm. The sides also manually roll up to provide ventilation and temperature control.
Tree boards from milled oak-wood scraps from the Glen Helen Preserve make up the edges of the raised beds within the greenhouse. Students and community volunteers built the raised beds just after the greenhouse was completed.
