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 ambient temperature, protecting its contents in cold weather.
Many commercial glass greenhouses or hothouses are high tech production facilities for vegetables or flowers. The glass greenhouses are filled with equipment including screening installations, heating, cooling, lighting, and may be controlled by a computer to optimize conditions for plant growth. Different techniques are then used to evaluate optimality-degrees and comfort ratio of greenhouse micro-climate (i.e., air temperature, relative humidity and vapor pressure deficit) in order to reduce production risk prior to cultivation of a specific crop.

    Crop King?

    Has anyone had experience with Crop King greenhouses and related equipment? In the past when I've put greenhouses, I just built my own. But a project I'm penciling out requires more precision. And, frankly, my time is limited these days. Anyway, just wondering. Thanks friends.

    Prefab Greenhouses

    So, I cleared some space down the fill from us that I think I'll put a greenhouse in. I'm also working a three phase plan that will necessitate much bigger greenhouses, if put into motion. In the past, I just built my own, but I could see the advantage of just bolting together a ready made...
