I purchase a lot of these in various sizes as per stated for the area and I found that it really doesn't hold enough water for 5 days. In a pot on my porch.

I bought five of these and put them in my five largest pots--and I only have to water my plants every two or three days! I live in South Carolina where it is very hot and sunny and my Oyas are worth more than their price.
Not excited

This porous terracotta vessel waters plants naturally and efficiently, right at their roots. With the Oya, the water doesn’t run off or evaporate like it does when you water at the surface. Simply plant the Oya in the ground and fill with water every few days. Your plants get exactly what they need and you save water and time.


It can be easy to forget to water plants and we often waste water when we do. GrowOya solves both issues, elegantly.

This terracotta watering system simplifies—and improves—the process of caring for your plants. Simply dig the Oya into the soil (with the spout exposed) and fill it up every few days. Boom . . . you’re done. The Oya and your plants work together to do the rest.

The Oya’s porous terracotta material releases water slowly near the roots, where it's needed. This method saves a LOT of water (up to 70%) because it reduces runoff and evaporation. Put one or more pots in places that the hose or sprinklers can’t reach. Or use them anywhere and everywhere for effective, efficient watering.

Founder Josh McWilliams wanted to water his rooftop garden sustainably. So when he discovered the “olla” (pronounced ‘oya’), an ancient way of gardening with terracotta pots, he saw a chance to change the way people care for their gardens today. Fellow Founders Kenny Torrance and Brant Cheetham joined and GrowOya was born.

With the time-honored wisdom of the Oya, you’ll save time, save water, and grow happier plants. more Their Story
