Pepin Olla Heart

The Olla Heart relies on the natural porosity of terracotta. When buried in soil, the clay allows water to seep out slowly through the vessel walls directly into the root zone, creating a consistent moisture level that adapts to the soil's dryness.

Depending on the ambient temperature, humidity, and your plant's specific water needs, a single fill typically lasts between 3 and 10 days. We recommend checking the water level after the first few days to gauge how quickly your specific plant consumes it.

Yes, the Olla Heart is designed for both environments. Just keep in mind that outdoor plants in direct sun or high heat will draw water from the vessel faster than indoor plants, so you may need to refill it more frequently.

It works best in standard potting mixes that allow for good soil-to-clay contact. If your soil is extremely loose or sandy, the water may release too quickly; if it is very dense or clay-heavy, it may release too slowly.

It is made of natural terracotta, which is durable but can break if dropped on a hard surface. Handle it with the same care you would a ceramic pot or vase.

To clean, simply rinse the vessel with warm water and a soft brush to remove any soil buildup. Avoid using harsh soaps, as the porous clay can absorb chemicals that might be harmful to your plants.
