Growstone® GS-1 Hydro Stones are a breakthrough, high-performance hydroponic growing media specifically engineered for a balanced air-to-water ratio. GS-1 Hydro Stones deliver 67 percent more water retention and 12 percent more aeration than clay pebbles. They can be used in simple hydroponic systems, such as manually irrigated containers, or in advanced systems including automatically drip-irrigated containers, ebb and flow systems and NFT tables. The sustainable, earth-friendly media are made from 100 percent recycled glass and are 100 percent American-made.
