Greenhouses & Polytunnels

Polytunnels and greenhouses are both structures used to grow plants that require more heat than is available outdoors. Both are designed to capture and keep heat, but in different ways. Greenhouses use glass or polycarbonate plastic panels set in a metal frame to focus sunlight whereas Polytunnels consist of a plastic sheet, which is typically either clear, opaque, or green, stretched over a series of aluminum arches.
