Why Choose the Summit 12x16 Greenhouse Kit for Your Garden?
The Summit 12x16 Greenhouse Kit offers a spacious, durable, and attractive solution for year-round gardening. With its barn-style roof, robust aluminum frame, and high-performance polycarbonate panels, this greenhouse is designed to thrive in all seasons—whether you're just starting out or you're a seasoned green thumb.

Key Benefits
Engineered for All Seasons Crafted with a heavy-duty 1.6mm aluminum frame and 10mm UV-protected twin-wall polycarbonate panels, the Summit 12x16 ensures excellent insulation and weather resistance. From harsh winters to scorching summers, it provides a consistent growing environment year-round.

Superior Ventilation and Accessibility Eight manual roof vents offer excellent airflow to keep your plants healthy and prevent overheating. The smooth-gliding double doors are mounted overhead to avoid sticking and are built for frequent use. A magnetic latch with key lock adds both convenience and security.

Enhanced Stability and Convenience This greenhouse includes essential extras like built-in rain gutters, a drain kit, a snow load kit, and an anchor kit. Reinforced with cross-roof trusses and cross-corner bracing, it's built to stand up to wind and snow while staying secure in your garden. Stainless steel hardware ensures long-term durability.
