The light, almost fluffy, texture of FoxFarm's Ocean Forest potting soil makes it one of the company's most popular. This soil’s lightness comes from a blend of aged forest products, sandy loam and sphagnum peat moss. The powerhouse blend is rounded out with bat guano, crab meal, earthworm castings and fish emulsion. Founded in 1984 out of a desire to make garden soils that were not sterilized, FoxFarm has developed a line of all-natural soils that help your plants come alive. each bag fills 1-1/2 cubic feet.
