Soil Moist
Soil Moist is a product used as a media to release water into all types of soils.  It absorbs water, similar to a sponge.  When the surrounding soil dries, the water is released to the soil.  Consists of clear polyacrylamide granules which absorb up to 600 times their own weight in water, becoming soft and jelly-like.  With sufficient water, one 5 g package expands to fill a 500 ml (2 cup) volume.  If being used entirely on its own as a TRANSPARENT SOIL, water-soluble fertilizer must be mixed with the water before adding to granules.  We use it to demonstrate our Teaching Tank.
