ABSTRACT:
The invention relates to a method for the mineral wool culture of plants, whereby water and any fertilizers that may be comprised therein are supplied to, and if necessary discharged from, the mineral wool in which the plant grows, whereby in said mineral wool the suction pressure is adjusted using a capillary system connected for liquid communication with mineral wool, with which capillary system water and any required nutrients are actively supplied to and/or discharged from said mineral wool, in order to readjust the predetermined suction pressure; and to a device for the mineral wool culture of plants, comprising: mineral wool in which the plants can grow; means for supplying water and any fertilizers that may be comprised therein to said mineral wool; and means for discharging water and any fertilizers that may be comprised therein from said mineral wool, wherein a capillary system connected for liquid communication with said mineral wool, to which system are linked means for adjusting the suction pressure in said mineral wool in which the plant grows, and means for determining the actual suction pressure of the mineral wool, and based on the determined actual suction pressure control the amount of water supplied by the water supplying means and/or discharged by the water discharging means.
