Hydroponic Herbs: How to Grow Them at Home

Hydroponic gardening is becoming increasingly popular among garden enthusiasts due to its various benefits, including the ability to grow plants all year round, faster growth rates, and the ability to conserve water. One of the most popular plants grown using hydroponic systems is herbs. In this article, we will discuss the various hydroponic herb growing techniques, benefits of hydroponic herb gardening, and the steps to grow herbs hydroponically at home.

Benefits of Hydroponic Herb Gardening

Year-round Growing

One of the most significant benefits of hydroponic herb gardening is the ability to grow herbs all year round. Hydroponic systems do not rely on the weather or seasons, and therefore you can grow your favorite herbs regardless of the weather outside.

Faster Growth Rates

Hydroponic herb gardening enables you to grow plants much faster than traditional soil gardening. This is because the plants have constant access to all the nutrients they require, allowing them to grow faster and healthier.

Water Conservation

Hydroponic systems use up to 90% less water than traditional soil gardening. This is because the water is recirculated throughout the system, and the plants only take up the water they require, minimizing wastage.


When growing herbs hydroponically, you do not require any pesticides or herbicides. This is because hydroponic systems are usually pest and disease resistant, and any infestations can be easily dealt with without the use of chemicals.

Hydroponic Herb Growing Techniques

Deep Water Culture (DWC)

The deep water culture method is the simplest and most popular method of hydroponic herb growing. It involves suspending the plant’s roots in a nutrient-rich water solution, with an air stone providing oxygen to the roots.

Drip System

The drip system involves dripping a nutrient-rich solution onto the plants’ roots at regular intervals. This method is easy to set up and maintain, making it ideal for beginners.

Nutrient Film Technique (NFT)

The nutrient film technique involves suspending the plants’ roots in a shallow nutrient solution. A thin film of water is then continuously circulated over the roots, ensuring they are consistently moist.

Wick System

The wick system is the simplest hydroponic herb growing method, involving suspending the plant’s roots in a nutrient-rich solution and allowing a wick to transport the nutrients to the plant’s roots.

How to Grow Hydroponic Herbs at Home

Step 1: Choose the Right Herbs

When selecting the herbs to grow hydroponically, it is essential to choose plants that do well in hydroponic systems. Examples of herbs that thrive in hydroponic systems include basil, mint, parsley, and thyme.

Step 2: Choose the Right Hydroponic System

Choose a hydroponic system that suits your space and budget . There are many types of hydroponic systems available, including deep water culture, drip system, nutrient film technique, and wick system.

Step 3: Set Up the Hydroponic System

Follow the manufacturer’s instructions when setting up your hydroponic system. Ensure that the system is placed in an area with access to electricity and water and that it is stable and level.

Step 4: Add the Nutrient Solution

Add the nutrient solution to the hydroponic system, following the manufacturer’s instructions. Ensure that the solution is at the right pH level for the herbs you are growing.

Step 5: Add the Herbs

Carefully add the herb seedlings to the hydroponic system, ensuring that the roots are fully submerged in the nutrient solution.

Step 6: Monitor and and Maintain the Hydroponic System

Once you have set up your hydroponic herb garden, it is important to monitor and maintain the system regularly to ensure healthy plant growth. Here are some tips for maintaining your hydroponic herb garden:

  • Check the pH levels of the nutrient solution regularly and adjust it as necessary to ensure that it remains within the optimal range for your herbs.
  • Ensure that the water level is maintained at the correct level for your hydroponic system. If the water level drops too low, the plants may dry out and die.
  • Check the roots regularly for signs of disease or nutrient deficiencies. If you notice any issues, adjust the nutrient solution accordingly.
  • Clean the hydroponic system regularly to prevent algae or bacteria growth, which can harm the plants.
