How To Grow Mint Indoors Using Hydroponics System

Growing mint indoors using a hydroponics system is an excellent way to have fresh, aromatic herbs at your fingertips all year round. Hydroponics is a method of growing plants without soil, using nutrient-rich water instead.

This method provides plants with the perfect balance of water, oxygen, and nutrients, resulting in faster growth and higher yields. In this tutorial, we will guide you through the process of growing mint indoors using a hydroponics system.

Understanding Mint and Its Varieties

Mint, scientifically known as Mentha, is a genus of plants in the family Lamiaceae. Mint plants are known for their refreshing aroma and flavor, which are concentrated in their leaves. They are used in a wide range of culinary, medicinal, and cosmetic applications.

There are several mint varieties available, each with its own unique flavor and growth characteristics. Some popular mint varieties for indoor hydroponics include:

Benefits of Growing Mint in Hydroponics

Growing mint in a hydroponics system offers several benefits:

  • Fast Growth: Mint grows faster in hydroponics compared to soil because it gets all the nutrients it needs directly from the water.
  • Year-Round Harvest: With hydroponics, you can grow mint indoors all year round, regardless of the weather outside.
  • Space Saving: Hydroponics systems are compact and can be set up in small spaces, making them ideal for urban dwellers and those with limited gardening space.
  • No Soil-Borne Diseases: Since hydroponics does not use soil, the risk of soil-borne diseases is eliminated.
  • Water Saving: Hydroponics uses less water than traditional gardening because the water in the system is recycled and reused.

Setting Up the Hydroponics System

To grow mint indoors using hydroponics, you’ll need to set up a hydroponics system. Here’s a step-by-step guide:

1. Choose a Hydroponics System

There are various types of hydroponics systems available, such as deep water culture, nutrient film technique, and ebb and flow. Choose a system that suits your space, budget, and gardening goals.

2. Gather the Materials

You’ll need the following materials to set up your hydroponics system:

  • Container or reservoir
  • Growing medium (such as perlite or coconut coir)
  • Nutrient solution
  • pH testing kit
  • Mint seedlings or seeds
  • Grow lights (if growing indoors without sufficient natural light)

3. Set Up the System

Follow the instructions provided with your hydroponics system to set it up. Generally, you’ll need to fill the reservoir with the nutrient solution, place the growing medium in the containers, and insert the mint seedlings or seeds.

Providing Optimal Growing Conditions

To ensure the healthy growth of your mint plants, it’s important to provide them with the optimal growing conditions:

1. Light

Mint plants require at least 6-8 hours of direct sunlight or 12-16 hours of artificial light per day. If growing indoors, use grow lights to supplement natural light.

2. Temperature

Mint thrives in temperatures between 65-75°F (18-24°C). Avoid exposing the plants to extreme heat or cold.

3. Humidity

Mint prefers high humidity levels, around 50-70%. You can increase humidity by placing a tray of water near the plants or using a humidifier.

4. Nutrients

Provide your mint plants with a balanced nutrient solution specifically formulated for hydroponics. Follow the instructions on the nutrient solution package for proper dilution and feeding frequency.

Maintaining Your Mint Plants

To ensure the healthy growth of your mint plants and a bountiful harvest, follow these maintenance tips:

1. Watering

Check the water level in the reservoir regularly and top it up as needed. Avoid overwatering, as it can lead to root rot. Maintain the water pH level between 5.5-6.5.

2. Pruning

Regularly prune your mint plants to encourage bushier growth and prevent them from becoming leggy. Pinch off the top leaves to promote branching.

3. Pest Control

Monitor your mint plants for pests such as aphids or spider mites. If you notice any infestation, treat it with organic pest control methods or insecticidal soap.

4. Harvesting

Harvest your mint leaves when they are mature and full of flavor. Cut the stems just above a leaf node to encourage new growth. Regular harvesting will keep your mint plants healthy and productive.

Frequently Asked Questions

1. Can I grow other herbs in the same hydroponics system as mint?

Yes, you can grow other herbs in the same hydroponics system as mint. However, keep in mind that mint is a vigorous grower and can outcompete other herbs for nutrients and space. It’s best to grow mint in its own container or section of the hydroponics system.

2. How long does it take for mint to grow in a hydroponics system?

Mint grows quickly in a hydroponics system. You can expect to start harvesting leaves in about 4-6 weeks after planting.

3. Why are my mint leaves turning yellow?

Yellowing leaves can be a sign of several issues, including nutrient deficiency, overwatering, or insufficient light. Check your nutrient solution, water levels, and light conditions to identify and address the problem.

4. Can I propagate mint from cuttings in a hydroponics system?

Yes, mint can be easily propagated from cuttings in a hydroponics system. Simply cut a stem from a healthy mint plant, remove the lower leaves, and place the cutting in the nutrient solution. Roots should start to form within a week or two.


Growing mint indoors using a hydroponics system is a rewarding and convenient way to enjoy fresh herbs year-round. By following the steps outlined in this tutorial, you’ll be able to set up your hydroponics system, choose the right mint variety, provide optimal growing conditions, and maintain your mint plants for a bountiful harvest.
