Scoria is a naturally occurring, porous rock created by fast-cooling lava. Its high surface area makes it ideal for aeration, nutrient storage, and improved drainage. Scoria is energy-efficient and eco-friendly, while its lasting quality makes it perfect for No-Til settings. It also retains some water, and its red brings a warm tone to any medium. Scoria is an excellent replacement for pumice.
Sold per bag, at approx. 20 liters per bag.
