These are the Original blumats Classics, the best automatic plant waterer on the market--the only authentic Austrian-Engineered plant stakes that are superior in design, material quality, and durability to inferior knock-offs (we are looking at you, plant nanny!)! Replace your finicky, expensive, automatic watering system with a blumat watering system. After years of testing, blumat has created one of the most efficient and reliable automatic watering devices on the market. The ceramic cone is porous and allows water to be absorbed and released when placed in wet and dry mediums. Works for all Types of Plants For cactus or plants that need less water, lower the reservoir to even (or below) the plant to only allow watering when the medium is almost completely dry. For tropical plants or plants that need more water, raise the reservoir and gravity will help give these plants the larger amount of water they need to thrive. Instructions 1. Fill a bowl with water. Remove the top of the blumat. Put both the into the bowl for at least 15 minutes. 2. Holding the cone and cap underwater, knock out the air bubbles and press the top on tightly. 3. Push the ceramic cone into the soil. 4. Put the hose at the bottom of the container of water. That's it! Silicone tube reaches about 38 inches.
