Hydroshale Expanded Slate Lightweight Aggregate
Hydroshale is used in aquaponics, hydroponics, aquariums, natural pools, green roofs, raised bed mulching, ponds, and more.
Hydroshale is ideal as an aquaponic media that is both lightweight and has a high surface area for nitrification.
Our ¾ inch Hydroshale is double screened and double washed for a 98 percent pure ¾” mix verses competitive products which can be full of fine particles that can clog grow beds if not screened out. Less fines provides better value than other expanded slate or shale. Also, no prewashing is required outside of the grow beds!
