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.
Claims24
A growing medium comprising:
- about 5 to about 95 weight % fibrous tree bark, based on the total weight of the growing medium;
- and
- about 5 to about 95 weight % fibrous wood components, based on the total weight of the growing medium,
- wherein the growing medium has a dry bulk density of about 48 kg/m3 or lower and wet bulk density of about 120 kg/m3 or lower.
1 more element
A growing mix composition comprising:
- about 40 to 85 weight % growing medium including fibrous tree bark and fibrous wood components;
- and
- about 15 to 60 weight % peat,
- wherein the growing medium has total porosity of 88 volume % or more.
1 more element
A growing medium comprising:
- about 100 weight % fibrous pine wood components,
- wherein the growing medium has a dry bulk density of 12.01 to 20.02 kg/m3 and wet bulk density of about 120 kg/m3 or lower.
