Frequently Asked Questions (FAQ)

What is the best covering for a greenhouse? For a portable greenhouse, the best covering is typically a clear polyethylene (PE) plastic sheet because it is durable, provides excellent light transmission, and is cost-effective. For specialized needs like maximum ventilation, a mesh cover is best, while a shade cloth is ideal for hot climates.

How long will 6 mil greenhouse plastic last? 6 mil greenhouse plastic typically lasts 1 to 3 years outdoors, as UV exposure and weather conditions will degrade it over time. Quality of materials, like the UV-resistant PE used in Eagle Peak covers, can influence longevity.

How to protect a greenhouse in high winds? Secure the greenhouse with heavy-duty anchors and straps, and consider using windbreak netting to reduce direct wind pressure. Regularly check and reinforce all connections before storms. Ensuring your replacement cover is tightly fitted to the frame is also crucial.

Should I cover my greenhouse in the winter? Yes, covering your greenhouse in winter is generally recommended to improve insulation and retain heat. This is especially important for protecting plants from frost. A solid PE cover, like the basic woven or premium replacement covers from Eagle Peak, is essential for winter use.

What is the best material for a greenhouse in a hot climate? For a hot climate, a shade cloth with 30-50% density is best as it reduces heat and sunlight while allowing airflow. The Eagle Peak 50% UV Protection Shade Cloth is specifically designed for this purpose. Avoid solid, clear plastics that trap excessive heat.

What is a major disadvantage of polycarbonate sheets? Polycarbonate sheets can become brittle and yellow over time when exposed to prolonged UV sunlight, reducing their clarity and structural integrity. For portable greenhouses, durable UV-resistant PE covers often offer a more flexible and cost-effective solution.

Final Recommendations

Your ideal greenhouse cover depends on your climate and gardening goals. For most gardeners, the Premium Replacement Cover with Roll-Up Windows offers the best mix of features for the price. If you battle intense heat, prioritize the Shade Cloth. For summer seed-starting and pest control, the Mesh Cover is perfect.
