Self-watering for travelers & plant killers!
Meet Cowbell
Introducing the world's first pressure-regulated, self-watering kit. Keep your plants perfectly hydrated for weeks.
Invented by a traveler, for travelers.
Every Cowbell supports ocean conservation and food desert relief projectsHow Cowbells Work
Root-Controlled, On-Demand Watering
Plant roots and soil use capillary action to wick water from Cowbell's porcelain spike.
This capillary action causes the pressure inside the Cowbell reservoir to change.
The pressure change activates a thirst sensor inside the Cowbell lid to automatically open and close, letting air and water out based on the plant's needs.
- No batteries required
- Easy to clean
- Refill without removing from plant
- 4× lower carbon footprint vs glass
- Safe around kids and pets
