Green House & Tunnels

Green House

A greenhouse (also called a glasshouse, or, if with sufficient heating, a hothouse) is a structure with walls and roof made chiefly of transparent material, such as glass, in which plants requiring regulated climatic conditions are grown.These structures range in size from small sheds to industrial-sized buildings. A miniature greenhouse is known as a cold frame. The interior of a greenhouse exposed to sunlight becomes significantly warmer than the external temperature, protecting its contents in cold weather

Tunnels

Tunnels are passively vented, solar greenhouses that are used to lengthen the production and marketing season of vegetable and fruit crops . No artificial heating/cooling or ventilation system is used within the high tunnel, and the only external connection is water for drip or micro-irrigation. Most high tunnels are covered with a single or double layer of polyethylene plastic  if properly constructed and maintained. Crops within high tunnels are usually grown directly in the soil rather than artificial growing media, but soil-less substrates (perlite, compost, water) can be used for crop production within high tunnels.
