Garlic is a versatile and flavorful ingredient that is used in various cuisines around the world. Growing your own garlic can be a rewarding experience, but you may not have access to a garden or suitable soil. Fortunately, there are alternative methods to grow garlic without soil. In this article, we will explore the process of growing garlic hydroponically, which allows you to cultivate garlic in water-based solutions.


1. What is hydroponic gardening?

Hydroponic gardening is a method of growing plants without soil. Instead, plants are grown in water-based nutrient solutions, allowing them to absorb essential nutrients directly through their roots.

2. Why grow garlic hydroponically?

Growing garlic hydroponically offers several advantages. Firstly, it allows you to grow garlic in limited spaces, such as apartments or small balconies. Additionally, hydroponic gardening can result in faster growth and higher yields compared to traditional soil gardening.

3. What do I need to grow garlic hydroponically?

To grow garlic hydroponically, you will need the following:

  • Garlic cloves
  • Hydroponic nutrient solution
  • Container or hydroponic system
  • Water
  • Light source (such as grow lights)

4. How do I prepare the garlic cloves for hydroponic gardening?

Before planting the garlic cloves, they need to be prepared. Start by selecting healthy cloves from a bulb, making sure they are free from any signs of disease or damage. Peel off the outer papery skin, leaving the inner skin intact. This will protect the cloves during the growing process.

5. How do I plant the garlic cloves in the hydroponic system?

Place the prepared garlic cloves in the chosen hydroponic system or container. Ensure that the cloves are submerged in the nutrient solution, but not touching the bottom. The roots will develop and grow into the solution while the cloves sprout above.

6. What are the ideal growing conditions for garlic?

Garlic thrives in cool temperatures, ideally between 60°F to 65°F (15°C to 18°C). It requires a minimum of six hours of sunlight daily or equivalent artificial light. Maintain a pH level of 6 to 7 for optimal growth.

7. How do I care for the growing garlic?

Regularly monitor the nutrient solution levels to ensure the cloves are adequately submerged. Maintain the pH level by adjusting it as necessary. Additionally, provide sufficient light and ventilation to prevent mold or fungal growth.

8. When can I harvest the garlic?

Garlic typically takes around 90 to 150 days to mature, depending on the variety. Once the leaves turn yellow and begin to dry out, it is a sign that the garlic is ready for harvest. Carefully remove the garlic bulbs from the hydroponic system and allow them to cure in a dry, well-ventilated area for a few weeks.

9. Can I reuse the hydroponic system for future garlic crops?

Yes, the hydroponic system can be reused for future garlic crops. However, it is essential to clean and sanitize the system thoroughly between plantings to prevent the spread of diseases or pests.


Growing garlic hydroponically is an innovative and efficient way to cultivate this flavorful ingredient without the need for soil. With the right tools and care, you can enjoy a bountiful harvest of fresh garlic in your own home. Experiment with different varieties and techniques to find the method that works best for you. Happy garlic growing!
