As it is with new technology, hydroponic gardening can seem pretty confusing. There are just many variables to deal with, enough to make any faint-hearted novice call it quits. But having several variables does not mean that something is complicated as we will see below.
Hydroponic gardening is a new and innovative way of planting your favorite fruits or vegetables for optimal harvest. But achieving this optimal harvest demands efficient oxygenation of the roots. In the following article, we discuss oxygenation and then look at some of the recommended hydroponics air pumps, all to your benefit.

Why is an Air Pump for Hydroponics Necessary?
Basic science tells us that all living things require oxygen to live. But do plants breathe the same way we do? Of course, plant tissue needs oxygen to function well. However, we cannot say that plants breathe the same we do since they are minus the lungs – and the nose.
But plants respire and photosynthesize. The former happens at night and day, but photosynthesis only occurs during the day – aren’t plants the curious lot, but wait for it!
When plants photosynthesize, they take in carbon dioxide and give off oxygen. But during the night, the reverse happens through respiration.
Unlike animals, plants use every part to respire, and the roots are no exception. Roots need oxygen which they acquire through the little air spaces in the soil. That is why overwatering a plant, eventually kills it – you drown the poor plant!
The roots of hydroponics are basically underwater which makes it difficult for them to respire. That is why you need a water pump, and some air stones to diffuse air for roots and the normal respiration process continues – nothing should stop on account of some new planting technology.
Apart from providing a means for the plants to respire, the dissolved oxygen plays a vital role in preventing algae growth and diseases in the reservoir.
So which Factors do you consider when choosing the Best Hydroponic Air Pump?
As a standard, the least you need is a watt for every gallon of water. There is a formula you use to calculate the actual size but let’s stick with that for now. As a rule of the thumb, more is many times better than less. In other words, it would be better to be accused of providing the pants with too much oxygen and induce more plant growth than less of it leading to plant death – it’s a simple choice to make, don’t you think?
For commercial gardening where plants demand more dissolved air, the water pump should be at a minimum of 2.5 liters per minute. However, you will require an expert to set up the whole system effectively and advise you on a few things here and there.
Large indoors gardens require air pumps with numerous nozzles to provide the right amount of diffused air for the plants. Many nozzles are also ideal if planning to expand in the near future – ardent gardeners eventually expand, that’s growth.
Quality precedes price, always. If you are the kind of person that looks for the cheapest, make an exception if you at all you want something quality that will provide the sort of service to make the plants thrive – you are apparently into hydroponics for better harvests, and it would beat purpose going for something cheap. Look for extra features, as well as, durability, low maintenance, and ease of use.
Where pumps are concerned, noise is expected. While this might not be of concern to most people, check the sound a particular pump makes and determine whether you are comfortable to work in it.
To ensure that there is always dissolved oxygen for the plants at all times, you can get a solar-powered variety. The solar-powered will make sure there’s sufficient power flow powering the system. However, depending on the system, make sure that the power from solar energy is adequate – some big air pumps may find this power insufficient.
Our recommendation is based on the need to ensure your hydroponic system gets a consistent flow of diffused oxygen 24 hours in a day.
The Other Accessories that go with the Air Pump
It goes without saying that even the best water pump cannot work alone. Other accessories that go with the air pump include air stones and air lines.
Ideally, air lines should be food-grade, non-toxic and pretty durable. It should also be long enough to ensure some distance with the water pump if you don’t like the noise.
When it comes to air stones, chose the ones that produce the smallest bubbles for efficiency. The smaller the bubbles, the better for the plants as they absorb it readily.
Successful hydroponic gardening features the best hydroponics air pump among other factors. The above-listed products are pretty much what we mean when we talk about the best. However, our top choice spot rightly goes to EcoPlus 1030 GPH (3900 LPH, 35W) Commercial Air Pump.
If it’s not the pump’s heavy-duty construction and durability, then it must be its ease of use, high pressure, and decent output. It features six valves, adequate for medium and large reservoirs. The product’s die-cast aluminum construction is another feature to write home about.
