MGG ProGrow Series Greenhouse

Engineered for Canadian Winters. Built for Year-Round Growing.

Unlock true year-round growing with the MGG ProGrow Series greenhouse, specifically engineered for gardeners, hobby growers, and small farms operating in harsh Canadian climates. This greenhouse is not merely adapted for winter—it is structurally designed to withstand the winter conditions.

🌱 About the MGG ProGrow Series

The MGG ProGrow Series is a heavy-duty arched greenhouse developed with a clear focus on snow load resistance, long-term durability, and structural safety.

Its roof system is specifically engineered for snowy Canadian conditions and reinforced with an additional internal structure of heavy-duty steel pipes. This reinforcement ensures that even a thick, compacted layer of snow cannot deform or collapse the greenhouse, dramatically increasing reliability during prolonged winter storms.

Combined with a robust galvanized steel frame and X-structure triple-walled polycarbonate, the ProGrow Series delivers exceptional resistance to snow, wind, hail, and UV exposure — making it ideal for cold regions and unpredictable weather.

The result is a stable, protected growing environment for vegetables, flowers, herbs, and seedlings throughout all four seasons, with excellent heat retention and controlled ventilation.
