Greenhouse frame - Locks

A frame greenhouse is a small wood or metal greenhouse, often used for seeding or growing small plants in pots. It consists of a rigid frame, often made of aluminum or wood, covered with glass or polycarbonate glazing.

The glazing can be fixed or removable to allow controlled ventilation. The chassis greenhouses can be heated or not, depending on the intended use and the local climate. They are often used by amateur gardeners to prolong the growing season or to grow delicate plants.
