About
A backyard greenhouse provides a walk-in sheltered growing space about 10 feet long and over 7 feet tall.
Greenhouses range widely in scale, from small tabletop cold frames to commercial operations spanning dozens of acres. A typical home kit is tall enough for an adult to stand upright inside while walking between planting benches. Despite its room-like volume, the building remains lightweight because it uses hollow aluminum frames and thin polycarbonate or glass panels instead of solid walls.
From Wikipedia
In horticulture, a greenhouse is a structure designed to regulate the temperature and humidity of the environment inside it with a view to growing plants. There are different types of greenhouses, but they all have large areas covered with transparent materials that let sunlight enter and that inhibit the loss of the sun's heat.
