GrowOya is a Vancouver based company committed to helping you reduce your water usage in the garden. The Oya is a terracotta vessel that you plant in the ground and fill with water. Your plants will pull the water from the vessel as they need it reducing the water that simply evaporates off the surface of your garden. This is not a new idea but an ancient form of plant irrigation. Oya’s save water and reduce your time watering your garden!
