However, in the conventional spraying apparatus, the apparatus itself is relatively large-scale, has a complicated structure, is heavy, and is difficult to install in a greenhouse. However, there were difficulties that could not be installed unless they were rugged and robust, and that they were relatively expensive. Further, in the above-described watering apparatus, when water is supplied to a long hollow pipe provided with a large number of watering nozzles, the whole hollow pipe becomes considerably heavy, and there is a problem that the rotating operation is not easy. Was. In particular, when the above-described irrigation device is provided in a considerably large greenhouse, the hollow pipe must be made considerably long, and the weight of the water filled in the hollow pipe makes it difficult to manually rotate the hollow pipe. There was a disadvantage. Alternatively, even if it is barely rotated, it is difficult to continue this for a predetermined time. Further, when the hollow pipe is formed to be considerably long, there is a problem that it is difficult to uniformly supply water into the hollow pipe.
