Abstract

A growing medium includes a bulking agent compressed at a volume-to-volume ratio ranging from about 7:1 to about 10:1, being substantially free of a water-soluble binder material. The compressed bulking agent is then reground while substantially maintaining the volume-to-volume ratio.

Claims (24)

1. A reground growing medium, comprising:

a bulking agent, wherein a particle size of said reground growing medium is less than 0.4 inches in mean diameter; and

wherein said growing medium is compressed at a volume-to-volume ratio from an initial ratio of less than 3:1 to a ratio ranging from 7:1 to about 10:1 and then reground without reducing said volume to volume ratio to form an expanding soil mixture.

2. The reground growing medium of claim 1 , wherein said reground growing medium comprises a plurality of particles, wherein said particles have varying particle sizes, each particle size being less than 0.4 inches in mean diameter.

3. The reground growing medium of claim 1 , wherein said reground growing medium further comprises a water-retentive polymer.

4. The reground growing medium of claim 3 , wherein said growing medium is substantially free of water-soluble binder material.

5. The reground growing medium of claim 1 , wherein said bulking agent comprises coir.

6. The reground growing medium of claim 3 , wherein said water-retentive polymer is a non-foamed polymer.

7. The reground growing medium of claim 3 , wherein said water-retentive polymer comprises an acrylic polymer.

8. The reground growing medium of claim 3 , wherein said acrylic polymer comprises one of a polyacrylate/polyacrylamide copolymer or polyacrylamide.

9. The reground growing medium of claim 1 , further comprising seeds.

10. The reground growing medium of claim 1 , further comprising a fertilizer, nutrients, a pesticide, an insecticide, a fungicide, a plant growth enhancer or a combination thereof.

11. The reground growing medium of claim 1 , wherein the growing medium is initially compressed into at least one wafer, pellet, brick or slab.

12. The reground growing medium of claim 1 , wherein said reground growing medium is enclosed in a dehydrated package.

13. The reground growing medium of claim 12 , wherein said dehydrated package is vacuum-packed.

14. The growing medium of claim 1 , further comprising a non-ionic surfactant or emulsifier.

15. A method of making a growing medium to form an expanding soil mixture, comprising: compressing a dehydrated growing medium at a volume-to-volume ratio from an initial ration of less than 3:1 to a ratio ranging from 7:1 to about 10:1; and regrinding said compressed growing medium to a varying particle size of less than 0.4 inches in mean diameter.

16. The method of claim 15 , further comprising packaging said reground compressed growing medium.

17. The method of claim 15 , wherein said growing medium comprises coir.

18. The method of claim 15 , wherein said dehydrated growing medium comprises less than 15% moisture content.

19. The method of claim 15 , further comprising adding seeds to said reground growing medium.

20. The method of claim 15 , further comprising adding seeds or a water retentive polymer to said dehydrated growing medium.

21. The method of claim 15 , further comprising adding a non-ionic surfactant or emulsifier to said dehydrated growing medium.

22. The method of claim 15 , further comprising adding a fertilizer, nutrients, a pesticide, an insecticide, a fungicide, a plant growth enhancer or a combination thereof to said dehydrated growing medium.
