Why Do Plants Need Oxygen?

We all know that animals and plants use their respiratory systems to take in oxygen and release carbon dioxide. However, many people fail to comprehend that plants also need to consume oxygen. It’s hard to reconcile the two ideas.

In fact, once you realize that plants carry out two opposite activities, it makes sense. Photosynthesis and cellular respiration are two processes that take place in plants and animals, respectively, to convert sunlight into glucose and oxygen, respectively. Cellular respiration uses a significantly less amount of oxygen than photosynthesis produces.

Cells respire by turning oxygen and organic substances, such as glucose and amino acids, into energy and then exchanging water and carbon dioxide as waste. A major source of energy for the vast majority of living organisms is derived in this manner. Unlike mammals, plants produce their own sustenance through photosynthesis, whereas we obtain our glucose and amino acids from food.

Greenhouse gases like carbon dioxide and water are converted into chemical energy by plants using light energy from the sun, which releases oxygen as a byproduct. However, this oxygen can only be used in cells that possess chlorophyll and are exposed to sunlight for cellular respiration. A plant’s tissues that do not photosynthesize must obtain all of their oxygen from the surrounding environment.

For terrestrial plant roots, the oxygen they need to liberate this energy comes from pockets of oxygen that are embedded in the soil. However, too much water in the soil will suffocate the roots, preventing them from obtaining the oxygen they need to thrive. Reduced permeability, toxic accumulation, and food depletion can all result as a result of this.

The Importance Of Dissolved Oxygen In Hydroponics

You can see why it’s so vital to make sure your hydroponic system is producing enough oxygen now that you know why. In systems like water culture, where roots are immediately submerged in solution, roots will drown if there is not enough dissolved oxygen present.

Hydroponic aeration is necessary because water already contains oxygen, as in H2O. To learn more about dissolved oxygen, read on.

Because the oxygen atoms that compose water molecules are chemically bonded to those hydrogen atoms, they are inaccessible to plant life. While two oxygen atoms can be bonded together in a single water molecule, this is not the only possibility (O2).

Diatomic oxygen, molecular oxygen, and dissolved oxygen are some of the terminology used to describe this type of oxygen. In the atmosphere, oxygen gas is the only form of oxygen that can be found.

In the oceans and waterways of our world, life depends on dissolved oxygen for cellular respiration, the process by which organisms get their oxygen.

There are various advantages to hydroponically giving a large amount of dissolved oxygen aside from maintaining root system activity and preventing them from drowning. When growing plants in aeroponic systems, one advantage is that increased exposure to oxygen gas can significantly improve the ability of the roots to absorb nutrients, resulting in increased plant size and greater health.

Beneficial microorganisms like nitrogen-fixing bacteria thrive in nutritional solutions with adequate oxygen levels, which reduces the growth of root-rot-causing pathogens and promotes their development.

What Affects The Oxygenation Of Nutrient Solution?

The amount of dissolved oxygen in your nutrition solution can be affected by a variety of things. Purity of water is a significant consideration. The amount of oxygen that a liquid can store is reduced by the mineral content, salinity, and concentration of other nutrients, while organic pollutants like bacteria take some of the solution’s oxygen.

Before putting it in your reservoir, run your water through a reverse osmosis filter to get rid of these contaminants. That way, you’ll be sure to have the right amount of oxygen and nutrients for your plants. You can read my in-depth essay on hydroponic nutrient solutions here if you want to learn more.

The temperature of your nutrition solution can have a significant impact on the amount of dissolved oxygen in your solution. O2 is less stable at higher temperatures because of a rise in the solution’s temperature. Additionally, as the temperature rises, root tissue respiration increases, necessitating an increase in oxygen consumption. Roots, on the other hand, lose their ability to absorb water and nutrients when the temperature drops. Keep in mind that the recommended temperature range for root health is between 68 and 72 degrees Fahrenheit (20 and 22 degrees Celsius).

How Do I Increase Dissolved Oxygen In Hydroponics?

Increasing the amount of oxygen available to plants in a hydroponic system can be accomplished by ensuring enough aeration of the root zone. Using growing media like coco coir chips, perlite, or grow stones is one option. Selecting the finest growing media may be found here.

Another way to increase the nutritional solution’s dissolved oxygen content is to circulate it vigorously, which brings it into touch with the ambient air and allows it to collect more oxygen therefrom.

When it comes to increasing the amount of oxygen available to your plant roots, there are a few alternative options, but the safest and most effective way to do so is to use an air pump to aerate the nutrient reservoir with air stones.

Why Do I Need A Hydroponic Air Pump?

Using a hydroponic air pump isn’t just for increasing the amount of dissolved oxygen available to your plants’ roots. The following are a few more advantages to consider:

• Keeps the fluid uniformly blended and aids in the appropriate dissolution of minerals to increase the availability of nutrients to plants
• Algae growth in the nutrient solution reservoir is inhibited.
• Maintains a constant temperature in the nutrition solution.

Having established the numerous advantages of aeration, the question remains: Is the installation of a hydroponic air pump really necessary for a successful hydroponic garden?

It’s almost always true if you’re growing your plants in a deep water culture system, as the roots are continually in contact with the nutrient solution.

If you want to design a simple wick, drip, or Kratky system, you can do without a hydroponic air pump – but be prepared to accept lesser yield and increased disease and oxygen shortage hazards.

It’s possible to provide enough aeration in an active hydroponic system like nutrient film technique or the flow method by structuring it to create strong movement in the nutrient solution, such as by pouring it into the reservoir in a certain manner.

Hydroponics promises faster growth, larger plants, and higher harvests, but you need to aerate your nutrient reservoir using an air pump in order to attain these benefits.

What Equipment Do I Need For Aerating My Nutrient Reservoir?

All three of these components, along with the tubing, make up the greatest hydroponic pump installations. air pumps often lie outside nutritional solution tanks, pumping into the tank’s air stones, where it is dispersed into a multitude of microscopic bubbles.

Air Pump

When looking for the best hydroponic air pump for your purposes, these are some of the most important things to keep in mind:

• Make sure to verify the pump specs for a decibel level below 45 and seek for sound-reduction and oscillation-baffling features before purchasing an air pump for hydroponic use.
• Find air pump options that allow you to adapt to changing circumstances, such as variable airflow and multiple outputs.
• For this reason, you should look at the durability of any air pump you’re considering using in your hydroponic system.
• If your hydroponic system will be growing in the future, it’s a good idea to choose an air pump that’s a little bigger than you currently need.
• Economy of energy. Check out some of the energy-saving and environmentally friendly air pump solutions on the market to help limit your hydroponic system’s energy consumption.

How To Calculate Your Hydroponic Air Pump Sizing

The volume of your nutrient solution reservoir is required to figure out the appropriate size of your hydroponic air pump. For the sake of simplicity, you can assume that 1 watt of pumping power is required for every gallon of solution. Unless your hydroponic system is extremely complicated, a good range for air flow is 500 cubic centimeters per minute (0.5 liters per gallon).

Hydroponic Air Pump Noise

Vibrations from your air pump might be a huge annoyance when your hydroponic grow room is put up in your house. In the event that your hydroponic air pump lacks these qualities, there are a few tricks you can do to assist restore the peace and calm of your home once more.

A good place to start is by having your pump serviced to make certain that all of the internal parts are properly installed. In addition, polystyrene or another sound-absorbing material can be used to surround or even cover the pump. Try a bubble-wrapped cardboard box for a more creative solution. Take care not to obstruct the airflow! You can also reduce pump vibration by placing it on foam padding or a blanket. Consider using a bungee cord to suspend it.

Should I Run A Hydroponics Air Pump All The Time?

In order to avoid stressing your plants with variable dissolved oxygen levels and to extend the life of your air pump, you should run your air pump 24 hours a day, seven days a week. If you need to, you can turn it off, but only for brief periods of time.

Air Tubing For Hydroponic Air Pumps

You should use garden-safe plastic tubing to transport air from the pump to the air stones in your hydroponic system. Aquarium tubing is an excellent choice for this application. To avoid the growth of algae, keep an eye on the color of your tubing and choose for a dark shade rather than clear. And don’t forget to get a lot of air tubing so that you can move your pump around and connect it to numerous reservoirs and air stones with ease.

Air Stones

A common feature of aquariums is the use of air stones, which produce microscopic bubbles in the water that the fish need to breathe. They come in a variety of forms and sizes and are composed of porous materials like volcanic rock.

Oxygen diffusion in the nutrient reservoir is accomplished using a hydroponic air stone. As a result of the many tiny bubbles they create, the air pushed into the reservoir has a larger surface area, increasing the amount of oxygen diffused into the solution. Even more oxygen can be dissolved in smaller bubbles since they are less buoyant than larger ones, which means they rise from the bottom of the tank more slowly. As a general rule, the more bubbles in your solution, the better, unless you’re having trouble keeping it from overheating.

Hydroponics aeration can benefit greatly from the usage of air stones, which are affordable and readily available. Pump airflow rate and reservoir dimensions determine the number, size, and form of air stones you’ll require. It’s best to disperse air stones uniformly over the reservoir’s floor for larger tanks, however a single air stone will give you the most even bubble distribution. GroWell has a wonderful piece on air stones that you might find interesting.
