Purple Cow Activated Potting Mix offers superior performance because it’s scientifically formulated with our PCO Mineral Complex, so readily available nutrients not only get your plants off to a good start, but continue to feed your plants long after planting. Your lighter feeding edibles, herbs, and flowers will continue to receive nutrients and minerals for up to 2 months! It’s ideal for large or small containers and has excellent moisture-holding characteristics. It is also environmentally friendly because it contains organic fertilizer and less peat than most potting soils.
