Growing of plants, whereby a growth substrate surrounded by a plastic film in the form of a bag is used for the growing of roots, whereas the plant stem extends through an opening in the bag, and whereby the growth substrate is continuously supplied with water containing the additives necessary for the growth of the plants, and the water leaves the bag through one or more openings in the bag at the opposite end thereof relative to the stem opening. This growing is carried out with the bag being substantially vertically oriented. The watering water is collected and recirculated. For this purpose a growth bag is used, which is formed by a plastic bag with an opeining for the plant stem at one end and one or more openings at the opposite end. The bag comprises a porous growth substrate being appropriately hydrophobic and containing no soil, and it is adapted and shaped for vertical suspension. The bag is made of a light-impenetrable, preferably light-reflecting material. By the method a quick passing of nutrient fluid past the roots is carried out, and crop-carrying plants such as tomatoes, cucumbers, pepper, melons and beans may be grown in a high yield. By the growing, the mutual distance of the plants may in a simple manner be adapted to the growing step of the plants. |
