Vermiculite Coarse Particulate 6 cu. ft.
Vermiculite is an expanded clay mineral that is often used to retain moisture in soil. It also allows for better drainage. Use carefully - too much and your media will be soaked and too little and it will be too dry. A very useful product that allows you to control the moisture of your media very well.
This product allows soil to have better water or nutrient holding capabilities. Add accordingly. This is a great growing medium for hydroponic carrots, onions, radish and other tubular and bulb type plants that need a 12-inch depth for proper growth. For hydroponic applications, mix it with perlite at a ratio of one part vermiculite to four parts perlite.
