Cowbell makes plant watering easy by letting plants drink on their own for over 2 weeks. Works for indoor and outdoor container plants. Works best in soil-heavy potting mixes and plants in 6"-8" planters. Waters directly at the root. No over-watering, no root rot, no water waste.

Made from beautiful eco-luxury materials. Recycled and biodegradable packaging. $1 of every box goes towards ocean conservation and food desert relief projects around the world through 1% For the Planet. 

*Plant and planter not included. Not recommended for leca clay balls, semi-hydro or loose gravel substrates. 

Shipping calculated at checkout.

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 well 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.
  • Let spike saturate for 15 mins with lid off
  • Top up any drained water and seal with lid
  • Refill every 2 weeks.

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.

    I Have 20+ of These Now - They Are THAT Amazing

    I travel all the time for work, and was looking for a solution where my house sitter would not over (or under) water my large collection of plants. I'm a plant dad, so they are like my children. These Cowbells have made it easier than ever because they take the guesswork out of when your plant babies need to be watered + it is easy to tell someone to 'check the cowbells and keep them full' while you're away. This is honestly one of the best product innovations to come out of 2023!

    Very Happy Wife

    My wife was very genuinely surprised. She has flowers in almost every room in our home. We have water damage to hardwood floors in (2) rooms. She’s wishing we had discovered this system sooner. Thanks

    Happier houseplanting

    I wish I'd taken some "before" photos of a few of my most struggling plants....a bougainvillea, a classic Millennial monstera, a large alocasia that REALLY wanted to die on me....They were already a little sad, but when I moved them inside from my three-season porch, they all seemed ready to give up the ghost. The indoor heating, inconsistent humidity, sad midwestern winter light, and my staggering inability to adjust their watering needs, had me preparing for a mass burial.

    I took a chance and grabbed two 750 ml Cowbells at a local maker's market, and my plant game has CHANGED. I previously relied on water sensors and my very poor intuition when it came to watering in the past, but the Cowbell has turned my finicky plants into very happy, thriving beauties.

    No, Cowbells are not completely fool proof (depending on substrate, strength of the plants' roots, and some other factors), but are awesome enough that I've purchased MANY more. They're much less visually distracting than gravity waterers, and their simplicity and satisfying maintenance is PERFECT for someone like me. I love knowing that I can leave my plants unattended for travel, but even more than that, they've helped me keep my green babies alive and happy (even when I'm sitting in the room with them).

    Here's a photo of my bougainvillea about a week and a half after I started using Cowbell--the second is two months later. (Yes, there are still other sad plants along the edges. Working on it. ;) )

    Game changer!!

    CowBell is an absolute game-changer! Because of this genius mechanism, my plants have never been healthier, and now I can happily have thriving indoor plants. As a busy plant lover, this product is a true lifesaver, allowing me to enjoy greenery at home without the worry of constant maintenance. I wholeheartedly recommend CowBell to anyone who shares my passion for plants but struggles to find the time to care for them properly. With CowBell, I can't wait to expand my plant collection and make more purchases in the future!

    Plants love them. Excellent customer service.

    Jeanna is the owner/ founder / and an obvious plant lover amd very conscientious business owner. She will quickly answer any questions and trouble shoot until you solve any problems that may arise. I used the 750 cowbells on three of my plants and they are thriving. I have a very large avocado plant and wanted to be able to use them and she emailed back-and-forth with me many times to try to figure out how to use the cowbell, so that this large plant with a large planter could be sufficiently watered. The cowbells are not made for super large planters , but she has been trying to help me work it out because they’re so effective and efficient that I’d like to be able to provide this perfect moisture and watering to this plant.

    I am using these permanently. And not simply for traveling. My plants are able to drink as needed, and as I said, they are thriving. An Excellent product , with truly excellent customer service. I highly recommend cowbells.

    More Cowbell!

    If plants could talk, they'd say, "More Cowbell, please!" Cowbell is the VIP treatment my green friends never knew they needed. Sleek design, check. Foolproof watering while I'm away, double check. And the packaging? It's like unwrapping a gift you didn't know you needed but can't live without. My plants are thriving thanks to the consistent watering. Count me as a satisfied leaf—er, life—customer!
