When water is applied through rainfall or irrigation, a huge percentage is never utilized by the plant. This is primarily due to the forces of gravity pulling moisture back to the aquifer and evaporation pulling moisture into the atmosphere. While we can do little about gravity, we can reduce evaporative loss.
As soils dry down, water is depleted. As a result, only moisture vapor is left behind. Just as we can’t drink humidity out of the air around us, plants cannot use moisture vapor.
Hydretain was engineered to attract the vapor. Then it collects it back into microscopic liquid droplets to sustain turf and plants between waterings.
