The HydroHat Dripper evenly waters around the base of a plant. Available in 6”, 9”, or 12", diameters. They work in all types of pots and growing mediums and also in soil and hydroponic solution. A gap is purposely made on one side to allow it to be slipped over the stem without having to damage the plant. Each one comes with 3 removable support stakes which keeps the dripper in place and stable.
