What is claimed is: 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 rati
What is claimed is: 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.
