Greenhouse

A greenhouse is a special structure farmers and gardiners use. It expoits the greenhouse effect, that while glass is transparent to visible light, it traps heat inside, since glass is opaque to infrared light. A greenhouse can be used to grow tropical plants in a temperate climate. A greenhouse can be used to extend the growing season of plants. Plants can sprouted, in the greenhouse, and then transplanted, outside, when the weather is warm enough for the sprouts to survive.
