Keep your plants happy and healthy while you're away for a long weekend or short trip with our new and innovative waterers. Designed to fit onto bottle tops from 1¼" to 1½", this system automatically dispenses enough water to keep the soil around your plants' roots moist, but not saturated. Very easy to use—simply fill clean, empty bottles with water, attach the dispenser and insert it cone-side down in the soil. Perfect for both indoor and outdoor plants, and a great way to reuse unwanted bottles. Water bottles not included. 4½"Hx1 5/8" dia.
