How Often Do You Change Water In Hydroponics

If you’re unsure how often do you change water in hydroponics, make it a habit every two to three weeks. However, do note that your set-up, plant growth, and pH requirements are your considerations for changing your hydroponic system’s water. This might seem tricky, but remember that to reap the benefits of hydroponics, you have to accept that the absence of soil and sunlight puts you with more responsibilities to ensure your plants’ success. 

Using a hydroponic system, in addition to a greenhouse, makes it possible to grow healthy transplants. Hydroponics and greenhouses allow everyone to have a year-round supply of food, which would be impossible if you’re limited in location and space. However, using this technology includes being diligent throughout the process, especially with how often you’ll change its water.

How Often Do You Change Water In Hydroponics: What To Consider

 

Bi-weekly changing, but…

As briefly mentioned, you should change your water every two to three weeks. But before you do so, consider reading about the three considerations since they influence the frequency of changing the water. You might think that changing water in hydroponics is as simple as dumping and replacing it bi-weekly, but this is just based on one factor alone. 

This bi-weekly schedule recommendation is because, within two weeks, the volume of the water in the tank will be equal with the volume of the added top-off water. Changing bi-weekly will prevent hydroponics to over-accumulate nutrients, and to also prevent the bacteria and fungal growth. However, this frequency may vary based on your set-up, plant growth, and pH level. 

 

Hydroponic Set-up

According to the University of Massachusetts Amherst, one of the disadvantages of hydroponics is that you must have technical skills. After all, hydroponics is far from traditional farming, and you’ll be relying on technology and background in chemical and plant production for it to work successfully—this one of the reasons why your set-up will affect the frequency of changing your water.

For example, your set-up might lose water faster from evaporation and plant usage. Your system might have a lot of light, heat, or water reservoir close to these sources. Additionally, using many plants means higher water usage, so changing the water might be more frequent than the base recommendation. 

 

Plant growth

More than having many plants, the rate of your plants’ growth also dictates how often you’ll change the water in hydroponics. The high yield and short growing time advantages in hydroponics also mean that your plants’ efficient evaporation and transpiration will consume the water in the reservoir. Therefore, you must prevent water loss by adding periodically to maintain the water volume. 

You might have read the term “topping off” earlier, which means adding water to achieve a consistent level. You do this gradually to maintain the nutrients without having them too concentrated in the solution. Compared to changing water, topping off can be as frequent as every two days or every day.

 

pH requirements

One adjusts the hydroponic pH levels using products and additives that raise and lower it to achieve the recommended level. It’s also normal for the level to fluctuate when you change the solution, but it shall rise to the right level; however, if you notice that it’s consistently out of range, you need to change your water thoroughly. 

After all, pH additives are not meant to solve the fluctuations completely. And for your plants to grow well, the pH should be at the recommended levels. For a long-term solution, change your water out.  

 

How To Change Water In Hydroponics

The frequency of changing the water in hydroponics is crucial, but so is your method’s correctness for the changing itself. To put it simply, you’ll change water both by topping off and completely changing it. These two methods are essential, and they should be regular parts of your routines. 

Earlier, this article discussed topping off your water reservoir. From the name itself, you top off the reservoir with water to maintain its volume and prevent it from being too concentrated. Topping off can be daily or weekly, but the emphasis is necessary on measuring how much you add so you’ll know when it’s time to change your water thoroughly. 

On the contrary, changing the water completely would not be as frequent. And the reason why you need to note the volume of the water you topped off is that if they reach half of your total reservoir volume, then it’s time to change the water in your reservoir completely. 

 

Conclusion

The hydroponic system, combined with greenhouse gardening, can open gardeners’ opportunities to have food year-round without space and location limitations. However, one of its responsibilities that you must learn is how often do you change the water in hydroponics. Generally, you do this on a bi-weekly basis, and topping off the water can be weekly or daily. 

However, your set-up, plant growth, and pH requirements also affect how often you need to change your water. These factors may seem overwhelming to learn, but when you’re growing in hydroponics, you will surely be familiar with them anyway. Note how much you top your reservoir, and this will also let you know when it’s time to change the water completely.

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.
