I created the Self-Operating Watering Hose because sometimes you can take a really long time to water plants in a big courtyard or apartment balcony.
Also, sometimes people go away and can’t water their plants. You need a giant container that you have the soil in and the plants growing in it. One end connects to a hose which is used to fill up the channel/giant tube.
The small holes then slowly drip water onto the soil and plants. The sensors detect the water amount so that the plants don’t drown. It is adjustable for when the plants grow taller.
