How Do Cowbells Work?

World's first pressure-regulated technology lets plants drink on-demand for over 2 weeks without overwatering

Plants Drink On-Demand Using Capillary Action

Plant roots and soil can use capillary action to absorb water from Cowbell's vacuum-sealed water reservoir.

As your plant drinks, water and air leaves the reservoir, causing the pressure inside to also continually decrease.

A pressure-release valve inside the lid automatically opens and closes based on the plant's needs to regulate the pressure, letting air in and water out.

Precison-Pore Watering Spike

The Cowbell spike cone is made from natural porcelain engineered with precise pores that allow water to diffuse.

Because the reservoir is vacuum-sealed, water will not constantly drip from the spike by itself.

Cowbells are not drip irrigation systems.

Vacuum-Sealing Lid

Cowbell's lid keeps water in the reservoir suspended in a precise vacuum so water will not drip from the system into your plant by itself.

Pressure-Regulating Valve

Once the pressure inside the reservoir decreases to a specific level, the lid valve automatically opens and closes to let air in, which equalizes the pressure inside the reservoir, letting water diffuse from the cone to hydrate your plant.
