The T.O.P Spin Dripper Kits with Pump have been put together specially to streamline your grow room set-up like never before. These high-quality, pressure-regulated, drip irrigation systems are designed to be quick and easy to set up, and low maintenance for busy growers. They remove the effort of hand-watering and controlling the nutritional intake of multiple plants, by drip-feeding them using either one or two drippers per plant.
