Got the sprayer and refill bag, have a area about 12x12. Sprayed the area and watered 3 times daily and after 10 days nothing was growing, resprayed with the refill bag and after 10 to 12 days still nothing was growing. So I wasted $40 plus dollar on you product and got nothing in return. Will NOT use your product or refer it to anyone. User's recommendation: Never get you product.
