The Logica Drip Kit can be used to create a variable watering circuit that is ideal for potted plants, hanging baskets and planter boxes as well as for watering small areas and patios. Choose your watering cycle by simply turning the dial to any one of the 15 pre-set programs: Every 6 hours up to weekly irrigation. By using the pressure reducer with the Logica water timer, pressure is automatically reduced and maintained at a constant pressure of 14.51psi. The in-line drippers are adjustable for calibrated irrigation from 0 to 1.6 gallons and can be easily cleaned by unscrewing the dripper itself. Operates on one 9v battery (not included).
