The ollas aim to facilitate the irrigation of all types of plants while allowing a strong saving of water. Simply plant the ollas near your plants and fill them with water before letting the magic happen. These porous clay water tanks have the capacity to self-regulate the plants in water up to 10 days of autonomy by slowly and naturally spreading the water around it. A thousand-year-old system still considered one of the most efficient in the world and the most sustainable. The ollas allow everyone to grow their flowers, vegetables and more without any specific knowledge. This eco-responsible system adapts to all types of plants, whether they are in pots or in gardens. Moreover, they increase the productivity of vegetables and use up to 70% less water than conventional methods.
