Protected or greenhouse crops (i.e. those grown in glasshouses, plastic houses, and poly-tunnels) are predominantly those vegetables or ornamentals which cannot be produced economically outdoors, or which are in demand out-of-season. Typical of glasshouse vegetable crops are tomatoes, cucumbers, melons, beans and peppers. Smaller-scale businesses produce indoor and bedding plants, and are thus often linked to a nursery or garden centre.

Protected crops usually have high market value and are relatively expensive to produce, requiring specialist methods of cultivation, irrigation, ventilation, pest management andenvironmental control.
