How do I choose a hydroponic pump?

Your best indicator of water pressure is the “head height” rating. It takes pressure to pump water up, so the more GPH it can pump higher, the more water pressure it will have. The water pumps used for hydroponics are just simply submersible fountain and pond pumps that you can get at most home improvement stores.

Can you have too much oxygen in hydroponics?

Although most hydroponic growers are concerned with maintaining adequate oxygen levels, Baras said if too much oxygen is added to the solution it can cause root stunting. Using air pumps or air stones to add oxygen, the levels won’t be high enough to stunt plant growth.

Are air stones necessary for hydroponics?

Air stones and diffusers are an essential component in any hydroponic system, and are used with an air pump. Without supplemental oxygen in systems like DWC and ebb and flow, roots could suffocate.

How do I increase oxygen in my hydroponic system?

The most common way for hydroponic gardeners to oxygenate the water in their hydroponic system is by using an air stone. The reasoning is because air stones are inexpensive and easy to hobby hydroponic gardeners to find. The air stone is connected to an air pump that pushes the air through the stone.

You don’t have to refer to a fountain pump size chart to figure out the best water pumps for your garden.

What size pump do I need 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 pump do I need?

It is recommended that pond water is circulated at least once per hour. For example, if you have a 500 gallon pond, you need a pump that runs 500 gallons per hour at the height of the discharge. Therefore, if you have an 1800 gallon pond, you will need an 1800 GPH rated pump.
