Mason Jar Hydroponics


Hydroponics is the process of growing plants without soil. This method of gardening allows plants to absorb nutrients directly from the water. Mason jar hydroponics is one of the simplest and most affordable hydroponic systems available. In this article, we’ll explain everything you need to know about mason jar hydroponics.

What is Mason Jar Hydroponics?

The mason jar hydroponics setup is easy to assemble, and it can be done with simple items like a mason jar, a grow light, and some water. The mason jar is filled with an inert medium like sand, pea gravel, or perlite, and the plant’s roots are placed in the jar. Water is then added to the mason jar, along with nutrients like nitrogen, phosphorus, and potassium. The grow light is then placed at the top of the jar to provide the necessary light for the plants.

The benefits of mason jar hydroponics are many. For one, plants grown in a mason jar can grow faster and healthier as they are provided with all the necessary nutrients, light, and oxygen. This method of hydroponics is also cost-effective as it doesn’t require a lot of supplies and maintenance.

Overall, mason jar hydroponics is a great way to grow plants without soil, and it provides many benefits for both the plants and the growers. It is a great way to get started with hydroponics, especially for those who are new to the hobby.

Advantages of Mason Jar Hydroponics

The main advantage of mason jar hydroponics is that it requires less space compared to other hydroponics systems. This makes it perfect for people who are limited on space, such as those living in apartments. This method of gardening is more affordable than other hydroponics systems, and does not require specialized equipment.

Another advantage of mason jar hydroponics is that it is easy to maintain. The nutrient-rich solution used in mason jar hydroponics is relatively low in maintenance, as it does not need to be changed often. This makes it ideal for busy people who don’t have time to continually monitor the nutrient levels in their hydroponic system.

Advantages of Mason Jar Hydroponics

Easy to Set Up

Mason jar hydroponics is incredibly easy to set up. You don’t need any special equipment or materials – all you need are some mason jars, hydroponic nutrient solution, and a few other items. It’s a great way to get started with hydroponics if you’re new to the hobby.


Mason jar hydroponics is a cost-effective way to start growing plants. Compared to other hydroponic systems, mason jar hydroponics is quite affordable. You don’t need to invest in expensive equipment or materials, and you can easily reuse items you already have.


Another advantage of mason jar hydroponics is that it’s portable. This system is easy to transport, so you can take it with you if you move or travel.


Mason jar hydroponics can be used to grow a variety of plants, from herbs to vegetables. The system is also flexible and can be adapted to suit your needs.

Disadvantages of Mason Jar Hydroponics

The most significant disadvantage to Mason jar hydroponics is the lack of oxygen in the water. The oxygen levels in the water are much lower than what plants need to thrive. This can lead to nutrient deficiencies and poor plant growth. Additionally, because oxygen is needed to sustain the plant roots, plants may die if the water is not changed regularly.

Another disadvantage of Mason jar hydroponics is the potential for contamination. Since the water is not regularly changed, any bacteria or fungi present in the water can build up, leading to unhealthy plants and contaminated fruits and vegetables. Additionally, the water can become murky and cloudy, reducing the light available for the plants.

Disadvantages of Mason Jar Hydroponics

Limited Space

Mason jar hydroponics is limited in terms of space. Each mason jar only has enough room for a few plants, so you can’t grow a large number of plants in one container.

Difficult to Monitor

Since each mason jar is a separate system, it can be hard to keep track of the pH and nutrient levels of each jar.

Limited Nutrient Availability

The amount of nutrients available to the plants is limited by the size of the jar.


ou need to monitor the pH and nutrient levels of each jar, change the water regularly, and provide supplemental light if necessary.

How to Set Up a Mason Jar Hydroponics System

To create a mason jar hydroponics system, you will need a mason jar, some growing medium, a net pot, a water pump, and a nutrient solution. Start by filling the mason jar with your chosen growing medium, such as clay pellets or expanded clay. Fill the jar almost to the top, leaving a few inches of space at the top. Place the net pot in the center of the jar. The net pot should be slightly smaller than the mouth of the jar, so that it fits snugly.

The nutrient solution should be specifically designed for hydroponic systems and provide the necessary nutrients for plant growth. Once the nutrient solution is added, plug in the water pump and turn it on. The pump will keep the nutrient solution circulating, allowing the roots of the plants to access the nutrients they need.

How to Set Up a Mason Jar Hydroponics System

Place the plants in the net pot. Make sure the roots are submerged in the nutrient solution. Once the plants are in place, you can add a lid to the mason jar to keep the nutrient solution from evaporating. You should check the nutrient solution every few days to make sure the levels are sufficient for the plants.

A mason jar hydroponics system is easy to assemble and maintain, and can provide an easy way to grow plants without needing a large, complex system. With the right materials and nutrient solution, you can create a thriving hydroponic system in a mason jar.

Gather the Necessary Materials

The first step is to gather the necessary materials. You’ll need mason jars, a hydroponic nutrient solution, growing medium, and a reservoir.

Fill the Mason Jars with Growing Medium

Next, fill the mason jars with the growing medium. Make sure the medium is damp but not wet.

Add the Hydroponic Nutrient Solution

Add the hydroponic nutrient solution to the jars. Make sure the solution is at the right pH and nutrient levels.

Place the Plants in the Mason Jars

Place the plants in the mason jars. Make sure each plant has enough space to grow.

Place the Mason Jars in the Reservoir

Place the mason jars in the reservoir. Make sure the jars are secure and won’t move around.

Monitor the System Regularly

Monitor the system regularly. Check the pH and nutrient levels, and change the water if necessary.

Materials Needed for Mason Jar Hydroponics

Hydroponics is a method of growing plants without soil, using nutrient-rich water instead. One popular way to start a hydroponic garden is with a mason jar. Mason jars are easy to find, inexpensive, and can accommodate a wide variety of plant types. To get started with mason jar hydroponics, you will need the following materials:

Mason Jars

Mason jars are the foundation of mason jar hydroponics. You’ll need a few mason jars for each plant you’re growing.

Hydroponic Nutrient Solution

The hydroponic nutrient solution provides the plants with the nutrients they need to grow. Make sure you use a nutrient solution that’s specially designed for hydroponics.

Growing Medium

The growing medium provides support and drainage for the plants. Popular growing mediums for mason jar hydroponics include perlite, vermiculite, and coco coir.


The reservoir is where the mason jars are placed. You can use a plastic storage container or any other container that’s large enough to fit the mason jars.

How to Monitor and Maintain a Mason Jar Hydroponics System

How to Monitor and Maintain a Mason Jar Hydroponics System

Monitoring and maintaining a mason jar hydroponics system is essential for a healthy, productive system. Here are some tips for keeping your mason jar hydroponic system in top condition:

Monitor pH and Nutrient Levels

Make sure to regularly check the pH and nutrient levels of the system. If the levels are out of balance, you may need to adjust the nutrient solution or add supplemental nutrients.

Change the Water Regularly

It’s important to change the water in the mason jars regularly. This will help prevent the buildup of salts and other minerals in the water.

Provide Supplemental Light

If you’re growing plants that require a lot of light, you may need to provide supplemental light. You can use LED grow lights or other types of grow lights.


Mason jar hydroponics is a simple and cost-effective way to get started with hydroponics. It’s easy to set up and can be used to grow a variety of plants. However, it has some drawbacks, such as limited space and difficulty in monitoring. If you’re interested in trying out hydroponics, mason jar hydroponics is a great option.
