Electronic valve with a timer that runs on batteries, no electricity, no sun, and no wire extensions. The device is a hero. I installed it at my place and got rid of watering. It has a humidity sensor for rain. If it rains, it stops watering. You can cancel this feature. It's easy to program and the timer has many features. You can connect it to any water outlet you have, and it requires strong water pressure. Price: 140 ﷼
