Audo Copenhagen's Hydrous watering stick is the dream assistant for both the busy traveler and the somewhat absent-minded gardener. The watering bottle will keep your plants watered, easily and hassle-free. Just fill the stick with water and push the nozzle into the soil: the bottle will take care of the rest. The watering bulbs will keep your houseplants moisturized for up to one week depending on how thirsty the plants are – the perfect self-watering system for any busy gardener. The package contains two Hydrous watering sticks, which are also suitable for your outdoor plants.
