A METHOD AND A DEVICE FOR GROWING PLANTS IN MINERAL WOOL OR OTHER INACTIVE GROWTH MEDIA
专利汇可以提供A METHOD AND A DEVICE FOR GROWING PLANTS IN MINERAL WOOL OR OTHER INACTIVE GROWTH MEDIA专利检索，专利查询，专利分析的服务。并且A method and device for growing plants in mineral wool or other inactive growth media where the plants' consumption of water or nutrient solution is replaced with drip-feed watering or in some other way, and where the water content of the mineral wool is kept approximately constant. This is achieved by draining off superfluous water and passing the water through a pipe system. Both the water supply and the drainage of the cultivation mats (2) are performed by establishing hydraulic contact between the cultivation mats (2) and a simple pipe system, and by establishing in the pipe system pressure and underpressure conditions for water supply and drainage. This is achieved by providing a common pipe system for water supply and drainage. The pipe system is designed with a pump (8) for conveying water, at least two valves (10, 20 or 27) for establishing different pressure conditions in the pipe system and an outlet. In the pipe system there are further provided branch pipes in the form of drip-feed watering pipes (4) and drain-pipes (12) which terminate above the cultivation medium, or in the actual mat.，下面是A METHOD AND A DEVICE FOR GROWING PLANTS IN MINERAL WOOL OR OTHER INACTIVE GROWTH MEDIA专利的具体信息内容。
