Best Air Pump for Hydroponics


Hydroponics refers to growing plants in an environment in which soil is not present.

The word itself comes from two Greek words, hydro denoting water and ponics denoting labor. Hydroponics has become really popular because it provides nutrients and light to the plants in the right quantity and at the right time. It also maintains the proper temperature for the growth of plants.

So why do we need air pumps for hydroponics plants?

When plants are grown hydroponically, everything they need has to be provided by the gardener. And what do plants need to survive? Water, nutrients, light and air. When it comes to air, plants require dissolved oxygen (Do). Particularly for the roots.

If a plant doesn’t get enough Do, the roots rot and consequently, the entire plant dies off.

To maximize the level of oxygen to plants in a hydroponics growing system, an air pump for hydroponics is needed. When used with a high-quality air stone, the air pump can effectively increase the amount of Do.

An air pump for hydroponics generally consists of an air compressor which is attached to a delivery hose and at the end of the delivery hose, an air stone is connected.

Getting an air pump for Hydroponics – Things to consider

In a hydroponics system, you will need an air pump for hydroponics to push a minimum of 500 to 600cc of air per minute to your nutrient reservoir. This is enough for people doing indoor gardening. For people growing plants commercially, a more powerful configuration is needed.

The amount of noise the air pump makes is also something to consider. You, like most people, wouldn’t want a noisy pump.
