A GrowGrip is a low-cost, reusable plant holder used for deep water culture (DWC) applications in hydroponic and aquaponic growing. GrowGrips are designed to replace common plastic net pots and grow plugs. They are ideally suited for growing leafy greens, such as lettuce, in home and commercial applications. GrowGrips are made with a recyclable, food-grade, UV resistant low-density polyethylene foam, the same material used to package many common food products.
