Water Grip a US growing media company has recently patent a Horticultural Growth Medium that aims to grow more vigorous robust plants with fewer resources. The medium is claimed to hold more water whilst allowing the roots to access the air and nutrients they need.
The designers believe that rooftop applications will require no external irrigation plus stormwater runoff is both reduced and delayed.
The two inventors Allan M. Huberman and Bill Watson have developed a medium made up of composted bark, a carbon-based fibrous material, a hydrophilic polymer, sea solid, and beneficial bacteria/fungicide. The materials are formed into a solid substrate having structural stability, with both micro and macro interconnecting pores. The addition of a controlled release fertilizer provides for a perfect combination of nutrients, water retention, and pest and fungus control.
According to the designers the media promotes rapid, optimal root penetration to quickly stabilize plants, help them grow faster, and ensure long term plant health with a minimum of care. A high cation exchange ratio enables superior nutrient holding and availability. Ready access to water, air, and nutrients enables plants to grow faster with less stress to improve coverage. Healthy plants mean less maintenance, greater resistance to disease and beautiful results.
The Patent is US 8,756,862, dated June 24 2014.
