Medium-level greenhouses have vertical walls that are more than 2 metres tall but less than 4 metres tall, and a total height of less than 5.5 metres. They may have ventilation on the roof, the side walls, or both. Medium-sized greenhouses are typically wrapped in single or double-skin plastic film or glass, and they have variable degrees of automation. Medium-level greenhouses represent a reasonable economic and environmental base for the sector, since they strike a balance between cost and productivity. Medium-level greenhouse production can be more efficient than field production. Hydroponic systems make water use more efficient. Although there is more chance to apply non-chemical pest and disease management measures, greenhouse horticulture’s full potential is challenging to achieve.
