We have had 100 degree temperatures for 12 straight days with no rain in several weeks here in northwest Louisiana. Our neighbors all have irrigation systems. When we walk down the streets all of the other yards have brown spots. Ours used to be the same before Rachio. It waters less often in each zone than our old system did, but it waters much more deeply. Our yard is green and lush. Thank you for a superior (and easy) product.
