Long-time plant watering system.
Long-time system of watering plants - by analogy with a pet food for animals.
A bowl, buried in the ground, and on top is an inverted bottle (container) with water. The soil in the bowl is moistened to the limit and does not allow excess water from the bottle, which does not allow the atmospheric pressure to flow out completely. The water gradually spreads over the capillaries of the soil, and when it dries up, air flows to the neck of the bottle.
