Cold Climate Greenhouses (Zones 5–6)

Engineered for cold climates — Zones 5–6 covering the Midwest, New York, New England, and mountain states. Winters with heavy snowfall and sub-zero temperatures. All polycarbonate and glass models handle these conditions well. Aurora Glass is the strongest panel we offer. CASA Wooden performs best with a proper concrete foundation.
