Description

As a high-performance hydroponic aggregate media and soil aerator, the Growstone GS-1 714231 substrate provides an effective air to water ratio in drip irrigated containers, Ebb-Flow systems, and NFT tables. When the Growstone substrate is irrigated, water is held in the micro pores, but quickly drains through the macro pores, allowing fresh air to flow through the substrate. This process brings oxygen to the roots and removes carbon dioxide from the root zone. The combination of small and large pore spaces creates an ideal environment for roots, microorganisms, and worms to thrive, full of oxygen-rich water, and nutrients.
