How To Grow Wheatgrass Hydroponically: Two-Step Guide


Prepare the seeds

For a DIY hydroponic set-up, you need to prepare and sprout the wheatgrass seeds first. This is similar to how you’ll grow wheatgrass traditionally. To do so, rinse the seeds before putting them in a container, such as a quart-size jar.

Next is to submerge the seeds in the jar using purified water. Cover the container with the screen but remember to leave around 2 inches of the material so you can pull the edges down the jar mouth. Secure the cover with a rubber band and store it in a room at 65 to 75°F.

The seeds should soak for 12 hours before draining the water in the jar to help them sprout. Then, add purified water and shake the container gently to rinse the seeds. Drain and repeat the process to thoroughly clean the seeds. 


Put in container

Once you’ve cleaned the wheatgrass seeds thoroughly, spread them equally at the bottom of a grow tray. Add water to cover them, then cover the container itself with paper to make it warm and dark. This will encourage growth later on, and you can maintain moisture by soaking the paper cover.

Another method is to let the seeds sprout on their own in the hydroponic system for 24 hours. This is because growers noted how wheatgrass would need additional nutrients, and water alone won’t suffice. Therefore, it’s common to combine a hydroponic medium with kelp fertilizer or sphagnum peat moss.

Add an inch of growing media at the bottom of the tray before misting both seeds and media with water. However, be careful not to oversaturate them before storing the container in a warm and dark place. The wheatgrass should sprout on day four, and you can wait until they are an inch tall before placing them in a sunny location. 

Using a greenhouse is ideal for hydroponic wheatgrass because the indoor conditions prevent mold growth. After ten days, the grasses should be around 10 inches tall and ready for harvest. Just make sure you’re cutting as close to the growing surface as possible.


Advantages Of Growing Wheatgrass Hydroponically

Growing wheatgrass hydroponically is a sustainable and comfortable method compared to growing in soil. This is because you’ll be reaping quality wheatgrass while avoiding the problems and limitations with soil cultivation. If you’re planning on using a greenhouse, hydroponics is also your ideal partner.

If you think about it, growing wheatgrass hydroponically is more attractive since you’ll be consuming grass. After all, who would want soil and potential pathogens on their plate? In hydroponic wheatgrass, you’ll usually use coco coir, free of pathogens, odors, and possible mold problems. 

However, you might still be confused about why this article discussed the importance of not using plain water with hydroponic wheatgrass. 


Nutrient Requirements Of Wheatgrass

Some gardeners are adamant about growing wheatgrass hydroponically, thinking whether wheatgrass can still get their nutrient requirements and provide us with health benefits. Therefore, it’s useful to learn the macronutrients and micronutrients that wheatgrass needs.

Like most plants, wheatgrass loves nitrogen, potassium, and phosphorus. If you use coco coir for your hydroponic system, you shouldn’t have any deficiencies in these macronutrients. But because it is naturally low in nitrogen and phosphorus, it’s reasonable to add some coffee grounds for nitrogen and phosphorus. 

Micronutrients are not that easy to achieve hydroponically compared to using soil. Therefore, supplementation with fertilizer is better to ensure that your wheatgrass gets its needs. A fine example of fertilizer to provide micronutrients is liquid kelp, and you’ll just add it to the initial water bath of your system. 



Wheatgrass is a nutritional powerhouse that you can grow comfortably. If you know how to grow wheatgrass hydroponically, you can even avoid the drawbacks in space and pathogens common with soil cultivation. You only need to sprout the wheatgrass and use the appropriate growing medium for the hydroponic system.

The most common one is coco coir, and it’s best to add liquid kelp to ensure that the system provides the nutrient requirements for your wheatgrass. Speaking of which, it’s more viable not to use plain water in the system. Instead, add sphagnum peat moss in the hydroponic medium. 

Another useful tip for hydroponic wheatgrass is the use of a greenhouse. This way, you can prevent mold growth and maintain the ideal conditions to support germination growth. Wheatgrass should be ready when they are 10 inches tall.

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.
