The Compost Sak from High Caliper Growing is an affordable, convenient and efficient way to recylce kitchen scraps and yard waste into nutrient-rich, beneficial garden compost. The Compost Sak is constructed from a textile fabric that is lightweight, yet extremely durable, so it will last for years. The fabric is extremely porous, containing many micro-pores that allow for constant air circulation and for excess water to drain, thus creating the ideal composting environment.
