Understanding Your Plant House: From Site Selection to Ventilation

A plant house—whether a compact cold frame or a market-sized greenhouse—extends your growing season, protects crops, and turns any outdoor corner into a productive oasis.

Materials and Construction

Most use plastic sheeting over metal frames. Advances in polymers make them affordable, durable, and efficient. Choose UV-resistant, waterproof coverings like Gro-Tec for longevity.

Optimal Placement

South-, west-, or southwest-facing sites maximize sun exposure. In summer, ensure ventilation prevents overheating. Grow lights supplement low-light areas.

Size and Creativity

Smaller houses demand creative vertical growing. Larger spaces allow permanent frames with polycarbonate or glass. Match structure to your goals: seed starting, season extension, or overwintering.

Ventilation Is Critical

Without airflow, summer greenhouses become ovens. Install vents, fans, or automated openers to maintain plant health.
