Hydroponic cultivation system for greenhouse plants, e.g. snack cucumbers, comprises open cultivation channels and sea mineral nutrient composition for adding to water

摘要

The system comprises an open cultivation channel (12), a through-flow system for supplying and discharging water via a water conduit (8) associated with this channel, and a sea mineral nutrient composition for adding to the water. A cultivation system for growing greenhouse plants comprises at least one open cultivation channel which contains plants and includes a water conduit, a through-flow system for supplying and discharging water via this conduit, and a nutrient composition at least partially comprising sea minerals and added to the water continuously and/or periodically. Independent claims are also included for the following: (1) Nutrient composition used in this system; and (2) Method for cultivating plants using this system, comprising measuring the level of nutrients present in at least one cultivation channel, determining the desired level of nutrients and/or the desired nutrient addition times, and adding the determined amount of nutrients at the desired times.
