This efficient, water-wise system gives plants the slow, root-zone hydration they need to thrive. 6 sturdy sprinklers with built-in ground spikes and 360° nozzles deliver water in full circles up to 14' in diameter and can disperse 1 gal. in 80 seconds. Also included are six 180° heads that provide half-circle coverage up to 14' across and deliver one 1 gal. in 140 seconds. Simply place the sprinklers where you need water, use the garden hose to cross the areas where you don't, and attach the sprinklers to the hose. Garden hose can be cut to length. Kit also includes a pressure regulator. Add a timer, sold separately, and your garden will be watering itself!
