The term 'GROWING AREA' can be defined by two crossword solutions: GREENHOUSE (10 letters) and SEEDBED (7 letters). A GREENHOUSE is a structure with walls and roof made of transparent material, such as glass, in which plants requiring regulated climatic conditions are grown. Greenhouses are often used to protect plants from too much heat or cold, shield them from dust, wind, and excessive levels of sunlight, and to control humidity. A seedbed is an area of soil that has been prepared for the sowing of seeds. It is usually a shallow depression in the soil that is filled with loose, well-drained soil and is free of weeds and other debris. The seedbed is then covered with a thin layer of soil and watered to provide the ideal environment for the germination of seeds.
