Mint is a popular herb that is widely used in cooking, teas, and other beverages. It is also known for its medicinal properties and a pleasant aroma.

But, what about hydroponic mint? How does it differ from soil-grown mint, and is it worth it to grow it in a hydroponic system?

Read on below and discover everything you need to know about growing hydroponic mint!

What Types of Mint Are Best for Growing Hydroponically?

hydroponic mint growing hydroponically is so green and robust that it looks like faux plastic plants.

Mint is an excellent crop to grow in hydroponic systems due to its fast growth rate, low maintenance requirements, and high yields.

When it comes to growing mint in hydroponic systems, there are several species that work well including:

  • spearmint
  • peppermint
  • chocolate mint

So, no matter which sort of mint you prefer, rest assured it grows well and thrives in most hydroponic gardens.

How Fast Does Hydroponic Mint Grow?

hydroponic mint grows so quickly that it needs trimmed and thinned regularly or it chokes out other grow istes.

Hydroponic mint plants are easily started from seeds, or translated into hydroponic growing systems. Even more, they can typically be harvested within a single month of planting.

Due to their rapid growth rate, hydroponic mint plants require a balanced supply of nutrients to support them. Failing to supply your mint with a proper amount of nutrients results in tall and skinny plants with source leaves.

What is the Ideal NPK Ratio and EC Level for Hydroponic Mint?

The ideal NPK ratio for mint is 2-1-6 or 9-3-6 depending on the stage of growth.

The nutrient solution should also have an electrical conductivity (EC) level between 1.6 to 2.4 mS/cm for optimal growth.

How Much Light Does Hydroponic Mint Need?

Light is another key factor for growing mint in hydroponics as it requires at least 6 hours of bright light per day to thrive.

A combination of artificial lighting and natural sunlight may be necessary depending on your setup.

What are the Water Requirements to Grow Mint Hydroponically?

Water temperature is also important when growing mint in hydroponic systems.

Water temperatures between 60 to 70°F (15 to 21°C) will help promote healthy root development while preventing stress on the plant’s roots.

Suggested Hydroponic Systems for Growing Mint

There are several types of hydroponic systems that work well for growing mint.

That said, we suggest using one of three specific hydroponic methods for growing hydroponic mint, these include:

Deep Water Culture (DWC)

Nutrient Film Technique (NFT)

Aeroponics or Drip Irrigation

mint plants grow and thrive well in aeroponic grow systems.

All things considered, DWC systems are particularly popular because they allow for easy monitoring of nutrient levels while maintaining high humidity levels around the plant’s leaves.

Further, DWC cost the least to set up (or build yourself) and is all-around more affordable. They are also the easiest to learn how to use, as well as to upkeep, clean, and repair.

Are There Issues With Growing Mint in Hydroponic Systems?

Hydroponic systems are more than ideal for mint – not only does mint thrive hydroponically, but there are very few issues involved.

One thing, however, to keep in mind when growing mint in hydroponic systems is that it can quickly take over if not properly managed – just like they do outside in the garden or flower beds.

To prevent this from happening, it’s recommended to regularly prune the plant back regularly, and remove any dead or damaged leaves as soon as you notice them.

A Final Word About Hydroponic Mint Plants

Robust green hydroponically grown mint on a chopping block - it smells better, looks better, and tastes better than regular mint.

Overall, mint is an ideal crop for hydroponic gardening due to its fast-growing nature, low maintenance requirements, and high yields.

We hope this guide gives you all of the confidence you need to get started with this hydroponic crop.

With proper care given to their specific needs such as light levels, water temperature, and nutrient ratios – anyone can successfully grow hydroponic mint.
