FAQ: How To Determine The Size Of A Pump For Hydroponics?

To calculate the hydroponic pump size, you must first know the water volume you need to move and then the head height. If you have multiple growing chambers, you simply multiply the number of chambers by the water volume.

How big of a water pump do I need?

Pumps are rated in GPM (gallons per minute). A typical 3- to 4-bedroom home requires 8-12 GPM. When determining your home water needs, add one GPM for every water fixture in your home.

How do you size a hydroponic system?

Sizing a hydroponic system

  3. 500 heads per week x 5 weeks = 2,500 plant sites.
  4. 70 channels per section x 2 sections = 140 channels in entire system.
  5. 70 channels per section / 1.5 channels per 12” span = 46.6′ *round up to 47′
