1LB Water absorbing crystal,polymer, soil moist, Insect Water
Polymer crystals are one of those special items that are almost magical.Just add water to the white crystalline flakes and they absorb many times their size in the polymeric gel that forms.  One pound of the crystals makes about 15 gallons of hydrated crystals!The gel that forms swells by absorbing water into the crystals. Florists also use polymer crystals as a dirt-free way to store water and to keep cut flowers fresh for a long time. It takes about 45 minutes to hydrate the crystals, but 2 days is better if you have the time. The same polymer crystals can be rehydrated many times, as long as they keep water in them and do not dry out I have kept them for a few years.
