Preventing Evaporative Loss is Key
In order to understand how Hydretain Works, you must first understand the mechanism of drought. Simply put, when water is applied through rainfall or irrigation, a huge percentage is never utilized by the plant. This is due primarily 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 prevent most of the evaporative loss.
When there is adequate liquid water in the soil, Hydretain essentially lies dormant and serves no real purpose. It is when this liquid water is depleted and only water vapor remains in the soil matrix that Hydretain’s benefits can be seen. Plants cannot use vapor, so Hydretain was engineered to capture it and collect it back into minute liquid droplets that sustain plants between waterings.
