Did You Know?

Your plant's roots have almost as much power as a Dyson vacuum cleaner! That's why your plant is strong enough to drink water from Cowbell all by itself when it's thirsty.

Aren't plants amazing?

Everything you love about our Cowbell Classic 750mL in a petite 250mL size, perfect for all your plants in 3-5 inch planters.

Cowbell Mini makes plant watering easy by keeping plants self-hydrated for 1-5 weeks (depending on individual plant thirst needs).

Works for indoor and outdoor container plants. Works best in soil-based potting mixes. Not ideal for leca or semi-hydro substrates. 

Each Mini is made from sustainable and partially recycled materials and is packaged in a biodegradable gift tube. Plant and planters not included.


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.

No over-watering! No root rot! No water waste!

Science is awesome.

*Please note all plants are unique and some may drink slower or faster than 2 weeks depending on a variety of factors like plant type, plant age, ambient temperature, soil type, container size, container type, season, and prior watering habits. If you have any questions, please reach out to our 24/7 plant care help line. 1-888-98-PLANT

Set up your Cowbell in minutes!

  • Water your plant before use for the longest-lasting results. Don't worry about overwatering, Cowbell will wait until your plant has used up the water in the soil before drinking from Cowbell.
  • Twist and tighten the spike onto reservoir
  • Bury the spike into damp soil
  • Fill your reservoir with clean water.
  • Seal tightly with lid to create vacuum seal
  • Refill by simply removing the lid. Repeat the above steps for every refill.

Cowbell does not need to be cleaned regularly. But if you'd like for it to look pristine, it is easy to clean!

If you use Cowbell outdoors or in direct sun, or if you fill your Cowbell with rainwater, you may find some natural algae growth in the reservoir after a few months.

We recommend twisting off the spike and handwashing the reservoir with soap and water.

We don't recommend putting the lid or reservoir in the dishwasher as it may cause some warping at extremely high temperatures. 

The spike and cone are dishwasher safe but you can also rinse it by hand or clean it with a scrub brush if you find that anything has plugged the ceramic cone.


We stand behind the quality of our products and will replace any components within one year of purchase.
