Description
Top Shelf Expanded Shale helps to loosen soils dense with clay or sand. Top Shelf Expanded Shale is great as a hydroponic growing medium. The size of the shale helps create air flow providing oxygen critical to plant growth. Top Shelf Expanded Shale is a porous clay that is fired at high temperatures and never breaks down. After that process, the expanded shale may hold up to 38% of its weight in water. Adding this product to potted plants will help reduce the frequency of watering. Only one application is needed to improve your soil’s drainage permanently.
