A tubular sleeve for a plant germination substrate consists of a a polymer mass and nonwoven, bonded fiber material treated with fungicides, in which cellulose fibers predominate. The rest of the synthetic fibers have a size of 1.3 to 17 dtex and give the fiber material a porosity of 1000 to 1600 l/s.m 2 (air passage at 1.0 mbar). The fiber material is bonded by a binding agent and additionally contains fertilizer embedded in the polymer mass. |
