Plants in OR ECA® are typically watered by immersing the OR ECA® in water until it's fully saturated, then allowing the excess water to drain away. This is often done by placing the OR ECA® and the plant in a container, adding water until the OR ECA® is submerged, and then after 10-15 minutes, draining the excess water. It's also important to provide a nutrient solution since OR ECA® does not naturally contain any nutrients.
