Abstract
A method for making a growing medium includes a step of combining tree bark and/or wood components together to form an initial composition; heating the initial composition to a temperature greater than about 149° C. under steam in a pressurized vessel; processing the initial composition through a refiner with a plurality of opposing disks to obtain the fibrous growing medium, the refiner separating fibers from each other; wherein the growing medium has total porosity of 88 volume % or more.
Claims22
A growing medium comprising:
- about 1 to about 99 weight % fibrous tree bark, based on the total weight of the growing medium;
- and
- about 1 to about 99 weight % fibrous wood components, based on the total weight of the growing medium;
- the growing medium having a total porosity of about 88 volume % or more, based on the total volume of the growing medium and water holding capacity of the growing medium according to ASTM D7367-14 of about 400 to 1000 weight %, based on the total weight of the growing medium.
1 more element
A growing medium comprising:
- a combination of fibrous wood and bark components having a total porosity of about 88 volume % or more, based on the total volume of the growing medium, a container capacity of about 50 vol. % or more, based on the total porosity of the growing medium, and a moisture content of about 10 to 50 wt. %, based on the total weight of the growing medium.
A growing medium comprising:
- a substrate mixture of fibrous wood components and bark;
- about 10 to about 90 wt. % of the growing medium, based on the total weight of the growing medium, comprising fibers having an average length to width ratio of about 9:1 to 55:1,
- the growing medium having a total porosity of about 88 to 99 volume %, based on the total volume of the growing medium.
