Pepin Olla

It relies on soil moisture tension. Because the terracotta is porous, water naturally seeps out only when the surrounding soil is dry; once the soil is sufficiently moist, the flow stops, preventing overwatering.

Yes, the olla is designed for both environments. It works exceptionally well in outdoor containers during hot spells or for indoor plants that require consistent moisture levels.

Refill frequency depends on your plant's water needs, the soil type, and the ambient temperature. In most cases, you will only need to top it off once every few days to a week.

Over time, mineral deposits from hard water can build up in the pores. If you notice the water flow slowing down, simply soak the vessel in a mixture of water and white vinegar to clear the pores and restore its efficiency.

For the best results, bury the vessel deep enough so that the neck is just above the soil line. This ensures the water is delivered directly to the root zone while keeping the opening accessible for easy refilling.
