How Do Cowbells Work?
World's first pressure-regulated self-watering technology that lets plants drink on-demand
1. Root-Controlled, On-Demand Watering
Plant roots and soil use capillary action to absorb water from Cowbell's ceramic spike.
When roots are thirsty, capillary action creates a suction on the Cowbell spike, which causes the pressure inside the Cowbell reservoir to change.
2. Thirst Sensor In the Lid
The pressure change activates a thirst sensor inside the Cowbell lid which automatically opens and closes to let air in and water out based on the plant's thirst needs.
Through the magic of physics, your plants are able to "talk" to the Cowbell, telling it to let water out when thirsty.
No batteries required.
3. Vacuum-Sealing Lid
Cowbell's lid keeps water in the reservoir pressurized so water will not drip into your plant by itself.
No overwatering, no root rot.
That's why our system lasts longer than other self-watering globes on the market.
4. Precision-Pore Watering Spike
The Cowbell cone is made from natural porcelain engineered with precise pores that allow water to diffuse on demand.
When the lid is on, no gravity, no constant drip, plants drink on-demand.
When the lid is off, water flows quicker by gravity (e.g. good for moss poles or reviving hydrophobic soil).
Why are Cowbells Better?
Whether it's duration, quality, or ease of use, Cowbells win.
