Abstract: The invention provides a method of growing plants in a non-fibrous growth substrate, the method comprises providing at least one non-fibrous growth substrate comprising wetting agent, positioning one or more plants for growth in the growth substrate, characterized in that the wetting agent comprises ionic surfactant and the non-fibrous growth substrate is selected from the group consisting of urea formaldehyde foam, perlite, vermiculite, expanded clay, coco chips, coco dust, lava, pumice and mixtures thereof.

Abstract: The invention provides a method of growing plants in a mineral wool growth substrate, the method comprises providing at least one mineral wool growth substrate comprising binder and wetting agent, positioning one or more plants for growth in the growth substrate, characterized in that the height of the mineral wool growth substrate is at least 53 mm and the wetting agent comprises ionic surfactant.

Abstract: The invention provides a method of growing at least three plants simultaneously in mineral wool growth substrate, the method comprises positioning the plants for growth in mineral wool growth substrate so that the roots of each plant are positioned in a growth region, and irrigating the plants with irrigation water over a period of at least three days, wherein during the irrigation period at least one water content parameter as measured in the growth regions surrounding the plant roots varies over the set of all growth regions by not more than 45%, and wherein the growth substrate comprises binder and wetting agent, the wetting agent comprising ionic surfactant.

Abstract: The invention provides a method of growing plants in a mineral wool growth substrate, the method comprises providing at least one mineral wool growth substrate comprising binder and wetting agent, positioning one or more plants for growth in the growth substrate, characterised in that the wetting agent comprises ionic surfactant and there are plants grown in the growth substrate for a period of at least 3 weeks.

Abstract: The invention provides a method of propagating seeds, seedlings or cuttings in a mineral wool growth substrate, the method comprising: providing at least one mineral wool growth substrate comprising binder and wetting agent, positioning one or more seeds, seedlings or cuttings for growth in the growth substrate, characterised in that the wetting agent comprises ionic surfactant, and in the method the growth substrate is watered at least once per day.
