Which type polymer should I use?
Both the original Water Crystals and the potassium cross-linked polymers are quality products.
The potassium is the finest made in the industry.
The original Water Crystal has been field tested in agricultural applications for 12 years. The potassium has a life span of 5-7 years.
What size polymer should I buy?
The original comes in one size, unless you want to order a ton. Its granules are 0.85-2.5 mm when new and dry. They will hydrate to maximum sizes of 1/2-3/4 inch.
The potassium cross-linked copolymer comes in three sizes:
o A granular powder, <1mm;
o A mid gradation, 0.85-2.0mm; and,
o A large gradation, 1.7-4.0mm.
When fully hydrated, the granular powder is like a clear slurry and individual granules are indistinguishable. Each granule of the mid gradation crystals swell to 1/2 inch. The large gradation, up to 1-1/2 inches.
The mid gradation crystals are best for most horticulural, gardening and new turf applications. This is also the preferred size for neck coolers, cool ties and cool pads, and for most craft uses.
The granular powder is best in potting mixes, sandy and porous soil, and for dust abatement applications. It is also successfully applied to existing turf after aeration.
The large gradation has its best application in clay soils, where it actually breaks down the clay and keeps it in a more porous state. It is popular also for home crafts and decorations.
The finer the particle size, the faster the rates of absorption. Water Crystal Beads take the longest time to hydrate.
A hydrated crystal exposed to direct sunlight will decompose.
