Abstract
The invention relates to a grow-mat for cultivating plants, and to the production thereof, which grow-mat comprises a layer of mineral fibres cross-linked to one another by cured binding agent and treated with hydrophilic wetting agent, characterized in that in said grow-mat the principal direction of said mineral fibres extending in said layer extends in the longest dimension of said mat, in which preferably in both upright longitudinal surfaces of the grow-mat a curing oven profile is present, and/or the layer is a primary layer and at least two of said primary layers forming a secondary layer are present in a horizontal longitudinal plane of said grow-mat.
Claims13
Grow-mat for cultivating plants, comprising a layer of mineral fibres cross-linked to one another by cured binding agent and treated with hydrophilic wetting agent, characterized in that in said grow-mat the principal direction of said mineral fibres extending in said layer extends in the longest dimension of said mat and the subsidiary direction of said mineral fibres extending in said layer extends in the heightwise dimension of said mat.
Method for manufacturing a grow-mat for cultivating plants, comprising the forming of a layer of mineral fibres from fiberised mineral flakes, in which layer are included a cured binder for cross-linking of the mineral fibres in said layer and a hydrophilic wetting agent to enable wetting of said mineral fibres with water, and the cutting of said layer to a grow-mat, characterized in that said layer is cut such that the principal direction of said mineral fibres in said layer extends substantially in the direction of the longest dimension of said mat, and the subsidiary direction of said mineral fibres extending in said layer extends in the heightwise dimension of said mat, and that the cutting pitch is substantially equal to the height of said grow-mat.
