Healthy Plants from Production to Planting
Add STOCKOSORB® to your growing media to save on water and reduce wilt, and your crops will be healthy from your greenhouse to the garden center.



Plants Stay Healthy With STOCKOSORB®
STOCKOSORB® is an advanced hydrogel technology manufactured by Evonik, with a unique action that absorbs water in growing media, then releases nutrient-rich water back to the plants when needed. When mixed into growing media, it swells to many times its original size, absorbing water for later release.
Fact: One pound of STOCKOSORB® can absorb up to 30 gallons of water.
Why Growers Love It
By using only 2 pounds per cubic yard in most growing media, growers have a cost-effective way to maximize water resources, minimize labor inputs, reduce shrink and improve plant survival rates. Growers can reduce water use by up to 30% in production.
Passing the Success to Retail
STOCKOSORB® keeps plants healthier on the retail bench — it reduces shrink and extends shelf life by increasing the water-handling capacity of soils, minimizing fertilizer leaching and enhancing root growth.
“We automate the addition of STOCKOSORB® into our media. It results in less watering, reduced shrink and lower plant stress, which further equates to less disease and insects. What’s more is that GSI offers great technical and customer service. We will be using it for many years to come.”
