A method for producing a plant growth media, the method comprising:
- subjecting a wet fibrous microbial cellulose material to a homogenisation process to produce a plant growth media comprised of a pulp that comprises between 0.1 and 2.5 wt/wt % fibrous microbial cellulose, has a bulk density of 0.005-0.015 g/cm3, and has a particle size distribution such that the D90 is between 750 and 1500 μm and the D10 is at least 40 μm,
- wherein particle size distribution is measured by laser diffraction analysis (Mie Theory) if the concentration of the fibrous microbial cellulose is 0.1-1.0 wt/wt %, or measured with sieving if the concentration of the fibrous microbial cellulose is between 1.0 and 2.5 wt/wt %.
A plant growth media, the plant growth media comprising a pulp of fibrous microbial cellulose material, wherein the pulp comprises between 0.1 and 2.5 wt/wt % fibrous microbial cellulose, wherein the pulp has a bulk density of 0.005-0.015 g/cm3, and wherein the particle size distribution of the pulp is such that the D90 is between 750 and 1500 μm and the D10 is at least 40 μm, wherein particle size distribution is measured by laser diffraction analysis (Mie Theory) if the concentration of the fibrous microbial cellulose is 0.1-1.0 wt/wt %, or measured with sieving if the concentration of the fibrous microbial cellulose is between 1.0 and 2.5 wt/wt %.
A plant growth media comprising a pulp of fibrous microbial cellulose material, having a bulk density of 0.005-0.015 g/cm3 and a particle size distribution of the pulp such that the D90 is between 750 and 1500 μm and the D10 is at least 40 μm, wherein particle size distribution is measured by laser diffraction analysis (Mie Theory) if the concentration of the fibrous microbial cellulose is 0.1-1.0 wt/wt %, or measured with sieving if the concentration of the fibrous microbial cellulose is between 1.0 and 2.5 wt/wt %.
