Gravponics displacement is the time in minutes to displace the entire volume of liquid in a gravponics system.
gravponics displacement It is calculated by dividing the total volume of solution in gallons by the gallons per minute rate that is being added to the input side. For example: 1000 gallons of liquid at a rate of 10 gallons per minute would take 100 minutes to displace the entire volume of solution in a gravponics system.
