PURPOSE:To provide the title pot enabling water to be penetrated into the soil despite its hardness, so designed that the water level of a double-walled vessel with a feed water tank set up on the lower part of the pot is raised to a specified height and after a specified time, the water is ensured to return to the feed water tank again. CONSTITUTION:A double-walled vessel 5 with a feed water tank 3 set up on the lower part of a pot 2 is equipped with water level sensors 16, l7, 18, 19 in the feed water tank, and the upper surface of a case 1 is provided with an operating section 23, display 22 and upper water level-detecting sensor 24. The outside air is then fed, using a pneumatic pump 15 of check valve structure through communicating tubes 13,14 into the feed water tank to raise water through a water guide tube 6 toward the pot, and an irrigation is made for a specified time through a timer at a control circuit 29. |
