Extend the growing season with a cold frame mini greenhouse by Hanover! The perfect fit for a first-time grower or seasoned gardener, an open base cold frame uses solar energy and insulation to create a microclimate within your backyard garden or protection over your potted plants on the patio, porch, deck, and balcony. Use it to extend the growing season past the first fall frost, overwinter dormant plants, harden off young seedlings, or protect sensitive plants from extreme weather events. Sturdy, strong, and durable, our cold frames are constructed from double-walled polycarbonate panels to resist UV rays and aluminum frames to resist rust for long-lasting use. The easy yet effective venting system protects the climate inside your cold frame to moderate the temperature and maximize growing conditions. Adjustable latches allow proper airflow for optimal growth and preservation. Enjoy growing and nurturing your garden with Hanover.
