Why Oxygenate Water For Your Plants

Before you should know how to oxygenate water for plants in your greenhouse, you must understand why it is needed.

Roots that lack oxygen will most likely substitute other compounds, causing cell damage and increasing the possibility of developing diseases. Even if such is not the case, it will still cause calcium deficiency to plants.

Temperature positively affects oxygenation in water. The lower the temperature, the more oxygen it can hold. But this is not always the case, especially if during summer when it is scorching hot. 

Rainwater provides adequate oxygen for the plants unless it has been stored for too long. You can also get the same level of oxygen from rivers. However, you may not have access to these all the time. 

So if you have your greenhouse at home, this will be very useful to you.

 

Oxygenating Water For Plants In Hydroponics

In this article, we listed other ways on how to oxygenate water for plants.

 

#1 Using an air stone

For hydroponic gardeners, using an air stone to oxygenate water is very common. This method is inexpensive and very easy to find. Air stones come in many shapes and sizes; therefore, you can always get one to fit your hydroponic system. 

The air stone oxygenates the water by allowing the air pump to push air through the stones. Since it is porous, the air is split to create a bunch of large bubbles. 

Since the bubbles formed are large, they are not the most efficient. Large bubbles rise quickly that it almost does not touch the roots. But with hydroponics trending among plant growers, there are now many air stones that create a smaller bubble in the market. 

Another drawback of using air stone is they are breakable. So it is recommended to purchase one that comes with plastic reinforcement. Nevertheless, this method still provides for your hydroponic plants. 

 

#2 Using an automatic siphon system

Exposing the root system of the plant in the air provides oxygen to the root hairs. This process can be done by draining the hydroponic grow bed. You can remove the water from the hydroponic using a siphon. One of the most popular is the automatic hydroponic siphon.

The automatic hydroponic siphon comes in different types, such as the bell, loop, and u. Whichever style you choose, they all work on the same principle. A vacuum created by the siphon will suck the water out of the grow bed when the standpipe reaches a point filled with water.

 

#3 Giving an oxygen gap

In some hydroponic systems, plants acquire oxygen through the air gap. Place a nutrient solution in the grow bed. By doing so, you are certain that it will provide oxygen for the plant to breathe.

When the root system of your plant is strong and healthy, it can take in the oxygen. Just make sure that it touches the nutrient solution. The air gap between the plant root and the nutrient solution is where the plants can get oxygen. 

 

#4 Using an air diffuser

An air diffuser is another common way of adding oxygen to your hydroponic system. They are a bendable tube with holes that release oxygen in the water. Although air stone distributes air evenly, air diffuser has smaller bubbles, ensuring that it reaches most root hairs.

The large bubbles in air stones rise quickly, thus not allowing enough time to touch the root hairs. Smaller bubbles from the air diffuser stay in the water for more extended periods, thereby exposing the root system to oxygen; this ensures maximum oxygenation for plants. 

 

#5 Using a stirring pump

While using an air stone and air diffuser creates oxygen that the plants need, it also causes the fertilizer’s pH to rise. This increase is because the bubbles from these two methods react with the carbon dioxide in the air. Therefore, using these in longer periods is not advised.

One way to give out oxygen with too much carbon dioxide is by stirring the water at regular intervals. This process keeps the water dissolved oxygen stable and also prevents stagnation and growth of harmful bacteria. 

 

#6 Hanging the roots

If you are using a vertical hydroponic system or aeroponic system, you get the most oxygen for your plants. A hydroponic plant does not necessarily need to sit in nutrient water. Some plants can be suspended in the air, where the nutrient solution is sprayed or pumped.

In the most vertical hydroponic system, the nutrient solution is pumped to the top. Then it falls, dripping nutrients on the plant roots along the way. On the other hand, spraying the solution is the most favorable when you have an aeroponic system. 

 

Final Words

Ensuring that the plants get the necessary nutrients they need will yield healthier and more productive results. If you perform necessary steps on how to oxygenate water for plants recommended in this article, your efforts will surely be rewarded with excellent crops.

How To Prevent Root Rot In Hydroponics: 3 Useful Tips

If you’re a newbie gardener who’s looking to find ways to hone your skills, you’d want to learn how to prevent root rot in hydroponics even before this problem affects your plants.

Hydroponics can be advantageous to crops in more ways than one. However, it also comes with risks of diseases, such as root rot, which can be destructive or even lethal to your plants.

Unfortunately, there are no effective methods to recover the wilted parts that were affected by the root rot once it hits your plants. The only thing you can do if you do not want this catastrophe to befall your crops is to prevent it before it happens. Read on to learn more about this subject.

 

What is Root Rot?

Root rot is a disease that attacks the plant roots and causes them to suffer decay. This usually happens when a lack of oxygen supply occurs in the substrate.

To give you an idea, think about plant roots that are submerged in water that only has a little oxygen in it. Over time, the plant suffocates and dies.

Aside from rot and decay, this disease also leads to the proliferation of fungi that are naturally present in the soil. These include Rhizoctonia, Alternaria, Pythium, Botrytis, Fusarium, or Phytophthora. As soon as fungi colonies start to grow, they tend to target the weakened roots and infect your precious plant babies.

Once the plant becomes infected, they won’t be able to take in what they need to grow – water, oxygen, and other nutrients. When this happens, it won’t be long before the plant dies.

 

What is Hydroponics?

In case you’re not aware, the term hydroponic is derived from a Latin word that means “working water”. To put it simply, hydroponics is an art that involves growing various types of plants without soil. If you’re like most people, the first thing that comes to mind when somebody talks about hydroponics would be a picture of plants with roots suspended into the water without using any type of growing medium.

 

Avoiding Root Rot in Hydroponic Systems

Detecting and identifying root rot can be tricky. When your plants get infected, their leaves and roots gradually wither until the whole crop itself dies from the lack of nutrients, which is a common symptom of many diseases.

 

What causes root rot in hydroponics?

One of the requirements in hydroponics systems is oxygen. Without it, your plants are basically on the road to death. On the other hand, lack of such is one of the major triggers for root rot, and it must be avoided at all costs.

Just like when planting in soil, you loosen up the ground so that your plants’ roots can have their required intake of oxygen. That is the case for crops grown in aqueous solutions as well. If they cannot breathe, they would not be able to grow.

Another agent for root rot is the temperature. The last thing you would want in your system are parasites that leech nutrients intended for your plants and infect the water during the process. In common terms, these fungi are called molds.

One of the best breeding grounds for these is warm and moist areas. For this reason, if the water temperature inside your reservoir is high, then you are susceptible to it. Something as minor as letting the solutions exposed to sunlight can already be a risk factor.

 

3 Useful Tips on How to prevent root rot in hydroponics

There is good news! Root rot in hydroponics can be prevented! Just follow these tips:

Tip#1: Use the right air pump

If you do not want root rot to affect your plants, you merely have to avoid its causes. If you need oxygen, keep the water bubbling by providing an air pump of appropriate size, and also give importance to proper ventilation in the room.

 

Tip #2: Maintain the temperature

The temperature should be maintained within the 70 to 80 degrees F range. Get rid of any materials that can make your system vulnerable to infections, and make sure not to disturb your crops while they are trying to grow.

 

Tip #3: Get rid of the rotten parts

However, if you failed in preventing the disease, then the rotten parts should be removed immediately. Cut them off as there is no chance of reviving them, and focus on the potential new growth instead. Fix your hydroponics system and eliminate the risks.

 

Why Give Greenhouse Gardening a Try?

Greenhouse gardening offers numerous benefits to greens aficionados who dare to take their gardening experience to the next level. Aside from acting as a shield against the effects of inclement weather, a mini, hobby, or semi-pro greenhouse can also serve as a protective layer that keeps harmful bugs and critters at bay.

What’s more, its enclosed structure allows you to control your plants’ growing conditions including the temperature, light, moisture, and ventilation of the greenhouse’s internal environment. With a controlled environment, you’ll be able to extend growing seasons and grow plants that aren’t native to your area.

 

Conclusion

No matter how well-informed you are about how to prevent root rot in hydroponics, you cannot completely eradicate the risks. Therefore, to avoid the worst-case scenario, you should be prepared to sacrifice the infected for the sake of others. While you’re at it, consider trying your hand at greenhouse gardening as well.
