The Claber Idris Spike provides a simple method of supplying water to plants automatically when there is no one home. Designed for hassle free plant pot watering for up to 20 days, the Idris is easy to use and very quick and simple to install. Simply choose which dripper will provide the best watering to suit your needs (10cl and 15cl), and attach a plastic drinks bottle full of water to the BSP thread connection at the end of the spike. Then insert the spike into the soil right next to the plant you wish to water and a continuous supply of water will be provided. The integral spike anchors the Idris in the soil to prevent tipping. Specifically designed to be used with plant pots. Perfect for all home and office plant pot watering needs!
