The 5 Best Hydroponics Air Pumps

This article looks into the best Hydroponics Air Pumps you can quickly get online and at an affordable price. 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 meaning labor. Hydroponics has become 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.

Do you need an air pump for hydroponics?

When plants grow 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 oxygen the roots rot, and consequently, the entire plant dies off.

To maximize the level of oxygen to plants in a hydroponic growing system, a Hydroponic Air Pump is needed. When used with a high-quality air stone, the Air Pump can effectively increase the amount of dissolved oxygen.

Hydroponics Air Pumps 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.

What kind of pump do I need for hydroponics?

In a hydroponics system, you will need a hydroponics air pump 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 robust 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.
