Mint in Aquaponics – An Easy Guide for Successful Farming

Mint in Aquaponics

People are yearning for more chemical or pesticide-free farm produce. That is why aquaponics gardens are now prevalent, both for individual purposes and commercial ones. You can grow herbs in an aquaponics system, and mint is a great choice.

Growing mint in aquaponics is convenient since the plant takes less space and can grow quickly. Just like it is for any other aquaponics system, plant growth requires care and monitoring. We give you essential tips about growing mint in an aquaponics system.

Why grow mint in an aquaponics setup?

Mint is ideal due to its high nitrogen uptake. Aquaponic gardening also makes the mint flavor stronger as the system is controllable. There are many varieties of mint, but their uses are cut across. They are primarily used for culinary practices- salads, cocktails, lemonade, and tea preparations.

Mint is also used for hair rinsing, as mouthwash, and as a breath freshener. It is said to ease sunburn pain and is also a face astringent. It can be used as a space freshener or as a moth and bug repellant. Mint contains potassium, calcium, magnesium, phosphorous, and Vitamin C, which are crucial for nutrition.

Factors and requirements for growth

The aquaponic setup

Recommended setups include media beds, nutrient film, and Deep water culture techniques.


As you plant mint, provide a space of about 15-25 cm or have around 8-40 plants per square meter. Germination will take place 6-7 days after planting and will need a temperature of between 20-25 degrees Celsius. Mint can take 5-6 weeks to grow fully.

The pH requirements

It is recommended to keep the pH between 5.5-6.5 for mint to thrive.


You can grow your mint under 18-30 degrees Celsius, but the optimal range is 20-25 degrees Celsius. Temperatures that reach 27 degrees Celsius need shading nets as such can lead to leaf and stem tip burn.



A wide range of climatic conditions favors mint growth. For mint to grow well, it can also be placed in a slightly sheltered or sunny place.

Growing factors

You can incorporate mint among other crops like tomatoes to boost the taste and nutrient control. However, some mints are invasive, so growing mint exclusively is recommended for an aquaponics system. Mint has speedy growth, and one plant can even be enough for home use.


Mint will be ready for harvest, having reached 15 cm. However, it can grow up to 120 cm tall and spread over the rest of the grow bed. Harvesting mint is done best early in the morning before it becomes turgid or before the occurrence of temporary wilting. Mint is a perennial herb, and it may be productive for even up to 15 years. Harvesting can be done any time.

Final thoughts

You can grow mint in aquaponics and yield yourself good produce. Even though the plant will do well in aquaponics, farmers must practice special care for the crop’s growth requirements. If you maintain the specific conditions mentioned above, you will see your aquaponics mint thrive.
