The invention relates to a potting media and an aquatic grow system using soil-less potting media. The soil-less media consists of ground, double cell, walled reticulated foam, from the polyurethane family, polyester class. The foam is ground and placed in a one quart poly grow-bag having a series of small holes punched around the periphery, slightly above the bottom of the bag. An aquatic plant is then placed in the bag of ground foam mixture media and filled with water until the foam is fully soaked and will not float. The filled bag is then placed in the intended water environment to grow. Prior to shipping, the grow-bag is gently squeezed to reduce weight by 99% to reduce the weight for shipping. The media remains moist during shipping to keep roots and plant healthy.
