BEST DIY FOR YOUR PLANTS: NO PUMP AUTOMATIC WATERING!

The benefit of using an automatic watering system is that you avoid having your plants start to dry out, and you also wont accidentally soak your plants. The moisture is kept at the perfect level for your plants and you end up using less water!

There’s a lot of different automatic watering systems out there. These seem to work great however there has always been something preventing me from building them. They all require a pump. Personally I would prefer not to use a pump because I think they are expensive and makes a lot of noise. I went to the drawing board to see if I could come up with something different!

This system uses a micro controller and soil sensor to monitor the water level of your plants. If your soil is starting to dry out the controller will counter this by watering the soil until it is sufficiently moist again.

Instead of using a costly and noisy water pump, we are going to use a servo to elegantly open and crimp a water tube. So cheap. So easy.
