They've sometimes used by florists as a decorative "ice" because when it's hydrated, that's what it looks like. The stuff is also really good for use in flowerboxes and planter baskets, which typically dry out very quickly, so the roots of the plants end up baking. The crystals absorb a lot of water and release it back to the soil(planting medium) relatively slowly, so the there's some buffering to the moisture content of the soil and less stress on the plants.<br>Anonymousnoreply@blogger.com
