How Do Cowbells Work?
World's first pressure-regulated self-watering technology lets plants drink on-demand for over 2 weeks without overwatering
Pressure-Regulating Technology
Cowbells are like hamster bottles for your plants! Plant roots and soil can use capillary action to absorb water from Cowbell's ceramic spike.
As your plant drinks, water and air leave the reservoir, causing the pressure inside to change.
A thirst sensor (pressure valve) inside the lid automatically adjusts based on the plant's needs, regulating the pressure to let water out.
Through physics, your plants are able to talk to the Cowbell, telling it to let water out when thirsty.
Thirst Sensor
As the pressure inside the reservoir changes, the pressure sensor (valve) inside the lid automatically opens and closes to let air in, which equalizes the pressure inside the reservoir, letting water diffuse from the cone to water your plant.
Vacuum-Sealing Lid
Cowbell's lid keeps water in the reservoir suspended in an equilibrium so water will not drip from the system into your plant by itself (after ~30 minutes of equalizing inside your plant).
Precison-Pore Watering Spike
The Cowbell 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 after the reservoir has equalized.
Cowbells are not drip irrigation systems.
Let Your Plants Water Themselves!
That's how Cowbell's technology is able to let different plants self-regulate their own hydration needs.
On average, one Cowbell Classic should keep a plant in a 6"-9" planter hydrated for ~2 weeks and up to 5 weeks.
One Cowbell Mini should keep a plant in a 3"-5" planter hydrated for ~2 weeks and up to 5 weeks.
Why are Cowbells Better?
Whether it's duration, quality, or ease of use, Cowbells win.
If Cowbells aren't the best system you've tried, we'll refund your purchase.
