The U.S. Occupational Safety and Health Administration (OSHA) has declared these crystals to be non-hazardous. The product has been certified under 29CFR1910.1200.

OSHA does recommends that consumers use "good agricultural hygiene" when using them. In other words, don't mix the crystals with any kind of liquid that may endanger your plants or crop.

Water Crystals are inert. They will not be absorbed into plants or migrate into ground water.

Researchers at state university agricultural departments have conducted tests on soy beans, wheat, sunflowers, corn and turf grasses. They are attempting to quantify the effects of Water Crystals on fruit, vegetables and blue grass, and how it might be used to conserve water on lawns and gardens.

They estimate that 40-60% of all water consumption is used for gardens and landscapes.

Water Crystals hold nitrates, phosphates, potassium, iron, zinc, boron and other substances next to the roots or plants. Doing so, reduces the leaching of these elements into ground water. Preliminary research has shown that the crystals attract the bacteria and microorganisms essential to plant growth.

Water Crystals fill and release. With rain, normal watering or crop irrigation, the crystals expand to capture and retain excess moisture in the soil. This property reduces run-off.

When they dehydrate or empty through feeding roots, their shrinkage causes the soil to naturally aerate, reducing compaction and hardness.

Water Crystals have been shown to be 95% effective after 5-10 years use in stable soil.
