How Does Water Temperature Affect Plant Growth?

So, how does water temperature affect plant growth? Perhaps you’ve recently asked yourself this question. The truth is, the water temperature can have a significant impact on how your plants grow.

Any change in the temperature of the water will change the metabolic activity of the plant, as well as the aquatic ecosystems. In other words, it doesn’t matter if you’re growing houseplants or aquatic plants – water plays a critical role in their growth, as well as their development.

 

How Does Water Temperature Affect Plant Growth?

Watering Plants

Whenever you take the time to water your plants, be sure that the temperature of the water is just right. In case you’re not aware, the plant’s roots are extremely sensitive to drastic changes in water temperature. Should you use water that’s either too hot or too cold, don’t be surprised if your plant becomes damaged or stressed.

 

Is Root Temperature Important?

Gardening enthusiasts need to be aware of the fact that a plant’s root system needs to be at a certain temperature level for it to get the most out of the water and nutrients that it absorbs. The ideal temperature for the roots is around 68 degrees Fahrenheit.

At this temperature, you can be sure that the water that’s present in the substrate still has plenty of oxygen in it. Furthermore, if the root temperature isn’t right, the plant’s pump mechanism that’s present in the roots won’t be able to work.

When the temperature is low, it would be impossible for the root’s pump mechanism to work as effectively as it should. Conversely, when the temperature is high, your plant’s ability to take up oxygen from the water isn’t going to be efficient.

It’s important to note that high root temperatures, as well as a lack of oxygen supply to the plant, can lead to mold growth and the proliferation of bacteria.

 

Is Substrate Temperature Equally Important?

Greens aficionados need to ensure the maintenance of the ideal temperature in the substrate. If you thought that you can easily regulate the substrate’s temperature through watering, think again. Attempting to do so will require you to make use of extremely hot or cold water that could likely put your plant under a lot of stress.

Should the substrate temperature change, just use water with extreme temperatures. You’ll find out that in about an hour or so after you water them, the temperature of their substrate will be back to what it was prior to watering.

 

How Does Cooler Water Temperature Affect Plants?

As previously mentioned, the water temperature can have a massive impact on a plant’s metabolic activity. Under cool conditions, every activity that’s taking place in the plant slows down.

To give prove this point, a group of researchers did a study on wild rice that was grown in cooler waters. It was discovered that these plants produced fewer and shorter leave compared to wild rice that was grown in warmer waters. Additionally, they also discovered that cool-water plants tend to lose their ability to develop their reproductive structures.

 

 

 

What is Thermal Pollution?

Thermal pollution refers to the drastic increase or decrease in temperature levels of an ocean, river, lake, pond, or any natural body of water. Human influence triggers this condition.

It typically takes place when a facility uses water from a natural resource and puts the used water back at a different temperature. In most cases, these plants or industrial facilities utilize water in the process of cooling their machinery to maximize their ability to come up with better products.

 

How Does Thermal Pollution Affect Aquatic Plants?

The growth of aquatic plants is greatly impacted by the water temperature changes. In the event of thermal pollution where an introduction of unnaturally warm water takes place in a natural water body, the population dynamics of aquatic plants change as well.

For example, plant species that usually come in small numbers can densely inhabit a certain area when industrial facilities release warm water from heated roadways to waterways. Another example would be when the introduction of warm water into a natural body of water causes certain plants to float to the surface.

 

How Does Cold Water Affect Houseplants?

In most cases, houseplants are native to tropical regions. For this reason, they stress whenever cold water is used to hydrate them. In fact, studies show that certain plants could develop white spots on their leaves, and their buds drop when cold water is splashed on them.

If you live in a colder region, be sure to let the cold water warm to room temperature before you use it to water your indoor plants. While you’re at it, keep in mind that water additives can potentially cause harm to your houseplants when these additives settle in warm water.

 

How Can Hot Water Be Beneficial to Seeds and Vegetable Cuttings?

Hot water is routinely used in the seed industry and plant nursery to eliminate pathogens, as destructive insects. Furthermore, the seeds of certain vegetables such as carrots, eggplant, celery, and tomato are dipped into hot water to get rid of the bacteria.

 

Final Thoughts: How Does Water Temperature Affect Plant Growth?

Congratulations on knowing the answer to “How does water temperature affect plant growth?”. If you want to experience gardening as you’ve never had before, try your hand at greenhouse gardening. With an enclosed space to keep your plants safe from pests and bad weather, you can be free to create the optimal growing environment!

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.
