A hydroponic system should be designed to fulfill the specific requirements of plants with the most reliable and efficient method(s) of nutrient delivery. The three major plant requirements that a hydroponic system must satisfy are:

3) Protect against root dehydration and immediate crop failure in the event of a
pump failure or power outage.
