The concept of drip watering is simple: it is the slow, regular delivery of water directly to the root zone of your plants, keeping the root zone moist, but never saturated. Your plants receive the ideal amount of water at the ideal rate. They also retain their proper air and water balance and avoid the stress and shock of the "drench and dry out" cycle associated with conventional watering methods. This results in optimum growth and healthy plants. Success with a drip watering system is dependent on two basic goals that are not simple to attain:= Provide uniform flow from each individual dripper, regardless of water temperature or supply pressure.= Insure that drippers remain clog-free.Many drip equipment manufacturers claim these benefits, but only a RAINDRIP system meets this challenge.
