Cowbell is unlike any other self-watering product you've used before!
Cowbell's pressure-regulated reservoir and lid keeps water suspended in a precise vacuum which means water doesn't drip by itself.
Plant roots and soil draw water from Cowbell only as needed using natural biology and physics processes like root pressure, capillary action, cohesion tension and water diffusion.
Once the pressure inside the reservoir reaches a certain threshold, the lid valve automatically equalizes the pressure. This means your plant roots never have to work too hard to draw water from the reservoir, while also preventing Cowbell from dripping unnecessary water into your plant.
