Ebb and Flow
An Ebb and Flow is another all in one system that is recognized by its depth. The grow medium is located above the reservoir which pumps the nutrients and water to the roots at a set time and rate. This means that during the day the plant will go through spells of dryness. The nutrient solution is pumped into the medium and is slowly drained back into the reservoir again. The whole unit recycles the nutrient solution at timed intervals.
