Why is Oxygenation Important In Hydroponics?
Dissolve oxygen helps improve the plants’ health and strengthen their roots. Plants need oxygen as they undergo aerobic respiration. In this process, the plants release energy for nutrient uptake and root growth. In a water-based hydroponics system, oxygen is dissolved in as a nutrient solution in the water reservoir. That is why many hydroponic gardeners would invest in the best air pump for hydroponics.

How Does Hydroponic Air Pump Work?
Gardens and hydroponics system often differ in terms of needs. However, when compared to the other gardening equipment, hydroponic system equipment are more expensive. Gardeners would invest on equipment like aquarium water chiller, hydroponic tents, HPS grow bulbs, and hydroponic air pumps to ensure that the system gets all the nutrients needed.
The plants are usually placed in small tents. In these tents, plants are planted with a little bit of soil or completely soil-less, and then partially submerged into the water. The small tents have tiny air pockets to allow the dissolved oxygen to absorb into the plant roots.

Without an air pump, the water may stagnate and can accidentally drown the roots of your plant in the nutrient reservoir. The lack of oxygen can also produce Pythium. Pythium can easily kill the roots of your plants.
An air pump is used to diffuse the air into the water. Once you can see bubbles on the surface of the nutrient reservoir, it means that the oxygen is dissolved successfully. Aside from that, the bubbles will evenly mix the dissolved oxygen in your nutrient reservoir.
How To Calculate The Right Size of Your Hydroponics Air Pump
To get the right size of your air pump, it is very important that you get the size of your nutrient reservoir. It is a common rule that when you buy an air pump, it is important that you consider the wattage and the number of gallons of the nutrient solution that you use in your reservoir. However, many growers would often discourage this because it can drown your plants in the process. The right air pump for your reservoir should be able to provide at least 500 to 600 cubic centimeters per minute. This number can create at least 500 to 600 milliliters of dissolved gas per minute which is a safe amount for hydroponic gardening. (Source)
On the other hand, the best air pump for hydroponics in term of commercial gardening should be able to produce at least 2.5 liters per minute. You should also consider getting an expert to help you plan out your set-up to accommodate your hydroponic equipment such as your air pump, chiller, etc.

When choosing the best tubing for your hydroponics system, go for a garden-safe plastic. Many plastic tubes can be harmful to your plants. It is also best that you get a dark-colored tubing. Clear tubing is more susceptible to algae growth, especially if the line is a bit moist. You should consider getting an aquarium tubing. Aquarium tubing is designed to withstand algae growth.
Oxygenation is an important variable in hydroponics gardening, and one way of adding oxygen is by using air pumps. Air pumps allow oxygen to diffuse evenly throughout the reservoir. It does not only improve plant health and root growth, but it also gives better yields and abundant harvest.
