PROBLEM TO BE SOLVED: To provide a device for feeding a certain amount of water and nutrient water per unit time to plants in flower pots and planters for about 1 week to two weeks at a low cost, when dwellers are away from home by a trip, or the like. SOLUTION: This device is used for feeding water by effectively using a pet bottle which is a plastic vessel for beverages and able to keep a certain feed water pressure for a long time independent of water reduction in the vessel by opening a small hole 2 between the bottle neck and the central part of the bottle. The bottle has a specific stopper 10 and a cover for releasing water little by little to the outside. The bottle has a mechanism for holding it. Thus, a certain amount of water or nutrient water is automatically supplied per a unit time for a certain period without requiring an expensive water supply installation to crops in a green house. Further, in an arid land such as a desert, and the like, crops are raised without wasting water by feeding a certain amount of water little by little without using expensive facilities and powers. Thus, plastic vessels for beverages called PET-bottles discarded after use are effectively used. |
