How To Grow Rice Hydroponically Simplified

Comprehensive Guide On How To Grow Rice Hydroponically


Step #1. Seed preparation

The first step in growing rice hydroponically is preparing the seeds for germination. You can use any rice seeds or long-grain brown rice for hydroponics. To prepare them for germination, you must soak them for at least 36 hours and then dry for a whole day before the next step.


Step #2. Rice germination

Once the soaked rice seeds have dried for 24 hours, you can use a bucket for germinating the seeds. An accessible medium would be a mix of soil and compost and then fill it with water. Plant the seeds in the bucket, and they should germinate within two weeks. 

A useful tip to support germination is placing the container in the greenhouse. Indoors, you can adjust the temperature to a higher level, which is optimal for rice seeds. You can also check out production manuals from universities to understand rice growing better. 


Step #3. Maintenance

To simplify the technique of growing rice hydroponically, you can use a hydroponic pot for the seedlings. Ensure that you eradicate the soil from the roots to avoid problems and for easier nutrient uptake. The roots should be in contact with the system’s nutrient solution to guarantee growth. 

If you have the hydroponic system in the greenhouse, adjust the temperature to around 77°F to encourage the rice’s quick development. You can leave them on their own for six months before harvesting. At this point, you should familiarize yourself with the solutions that would be supportive of rice production. 


Step #4. Harvest

You can harvest the rice stalks as you would in a traditional setting. However, don’t forget to allow them to dry for two weeks by wrapping them in a newspaper. You can roast these dried stalks for an hour to make the hull removal easier for consumption preparation. 


What Hydroponic System To Use For Rice?

The methodology previously discussed is a simplified explanation of how to grow rice hydroponically. This should help you understand the concept of growing rice this way, but be free to adjust the techniques to what is suitable for your production system. The main takeaway here for you is to remember to have the rice roots submerged in water. 


The ideal system

Therefore, you can assume that the best system for those wanting to learn how to grow rice hydroponically is deep water culture. However, one might also be limited with their budget in choosing a hydroponic set-up. The challenges you will face in hydroponic rice would also include testing what methods you should do to grow after 180 days. 

For example, you have to be well-equipped with the hydroponic technique you chose. Some might be too technical and complicated, especially for rice. Always do your research before selecting a system permanently. 


The three factors to remember

The other factors to remember in choosing the hydroponic system for rice are what substrate you’ll use for growing, the nutrient solution, and how easy it would be to monitor the nutrient and air supply. Remember that growing any crop in a hydroponic system requires maintenance of the nutrient and air. 


Considerations In Growing Rice Hydroponically

After finding the appropriate system and technique, there are also other considerations that you must remember when learning how to grow rice hydroponically. This will let you anticipate drawbacks and create solutions early on. For example, growing hydroponic rice would produce a lower yield, meaning you will need to adjust your system to meet supply needs. 

More so, the growing cycle of rice takes around 180 days, which means growing rice hydroponically will only allow two production cycles in a year. You also need to take into account the practices that you must do after harvesting. However, this doesn’t mean that hydroponic rice production is a fruitless endeavor. 

Perhaps this system would work well for those with experience in rice production and hydroponic systems themselves. Over time, you’ll develop techniques from experience to have a successful production system. You can maximize the use of water and nutrients for your crops using hydroponics and reap the benefits of soilless production. 



Did you know that you can also produce rice in the absence of soil? Learning how to grow rice hydroponically may seem daunting, but one can simplify the methodology into four steps. The simplified version is germinating the rice seeds and growing them in your chosen system. 

However, be mindful of the techniques you’ll be comfortable with since rice is not the easiest crop to grow hydroponically. With a proper understanding of the system, monitoring, substrate, nutrient solution, and limitations, hydroponic rice can be fruitful.

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.



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.
