A household staple, Parsley, either curly or flat-leaf, is a hardy herb that adapts well to hydroponics. It’s not as quick-growing as basil or mint, but it’s certainly worth the wait!

Parsley prefers cooler temperatures, around 50-75°F, and needs a solid 8-10 hours of light per day. It also loves humidity, so misting your parsley plants occasionally can help them thrive.

So there you have it, five wonderful herbs that can kickstart your hydroponic herb garden. But remember, the best herb to grow is the one you’ll enjoy the most, whether it’s for cooking, making tea, or simply enjoying its delightful aroma!

Care and Maintenance of Hydroponic Herbs

Once you’ve set up your hydroponic herb garden and chosen your preferred herbs, the journey doesn’t stop there. Ensuring your herbs thrive requires ongoing care and maintenance. Let’s explore the key factors that can lead to a flourishing hydroponic herb garden.


When it comes to hydroponic gardening, proper lighting is critical. Most herbs require around 10-12 hours of light each day. However, it’s essential to adjust this according to each herb’s specific needs. For instance, Cilantro prefers slightly less light.

If your garden is situated in a location with limited natural light, you may need to invest in artificial grow lights. LED lights are an energy-efficient option that provides the full spectrum of light your herbs need to grow.

Water and Nutrient Management

In hydroponics, water isn’t just a hydration source; it’s also the medium through which nutrients are delivered to your plants. Therefore, maintaining the proper balance of nutrients in your water is crucial.
Most herbs prefer a pH range between 5.5 and 6.5. Maintaining this pH ensures that nutrients are effectively absorbed. You can use a pH meter to check the solution and pH up or down products to adjust the level.

As for EC, it measures the concentration of nutrients in your water. An EC of 1.5 to 2.5 millisiemens (mS) is often suitable for herbs. Monitor EC using an EC meter and adjust by either adding nutrients or water as necessary.

Temperature Control

Each herb has its preferred temperature range, and sticking to it can significantly influence your garden’s success. A general rule of thumb is to maintain a temperature between 65-75°F, but some herbs may prefer slightly cooler or warmer conditions. Always research and observe the specific needs of your chosen herbs.

Disease and Pest Control

Although hydroponics reduces the risk of soil-borne diseases, it doesn’t make your plants immune to all threats. Regularly inspect your plants for signs of pests or disease. Common pests include aphids and spider mites, which can be controlled using organic insecticides or introducing beneficial insects.

Prevent diseases by maintaining a clean system, avoiding overcrowding your plants, and providing adequate air circulation. If a plant does get sick, remove it immediately to prevent the spread to other plants.  Remember, hydroponics is an ongoing learning process, so don’t be disheartened by challenges along the way. Observe, learn, and make adjustments as needed, and soon enough, you’ll find the perfect rhythm to keep your indoor hydroponic herb garden thriving!

Harvesting and Storing Your Hydroponic Herbs

One of the most rewarding parts of hydroponic herb gardening is finally getting to harvest your fresh herbs. With proper techniques, you can ensure optimal flavor and encourage continuous growth. Additionally, learning how to store your herbs can maximize their lifespan and flavor.

When and How to Harvest

Knowing when to harvest is crucial for capturing your herbs at their peak. Most herbs are ready for harvest once they’ve developed full leaves. Generally, it’s best to harvest in the morning, when the plants’ oil concentrations are at their highest, translating to more potent flavors and aromas.

When harvesting, use sharp, clean scissors or pruning shears to avoid damaging the plants. Cut off the top third of the stems, making sure to leave a majority of the plant intact. This way, the plant can regrow for future harvesting.

Drying Your Hydroponic Herbs

Drying is a traditional way to preserve herbs and it also concentrates their flavors. To dry your herbs, bundle them and hang them upside down in a warm, well-ventilated area away from sunlight. Once completely dry, usually after a week or two, you can crumble the leaves and store them in airtight containers.

Freezing Your Hydroponic Herbs

Freezing is an excellent method for preserving your herbs while maintaining their fresh flavor. To freeze your herbs, wash and pat them dry, then chop them up. You can freeze them in ice cube trays with water or olive oil. Once frozen, transfer the cubes to a freezer bag for long-term storage.

Storing Fresh Herbs

If you prefer to keep your herbs fresh, they can be stored in the refrigerator. For soft herbs like Basil and Cilantro, trim the stems and place them in a glass of water, just like a bouquet of flowers. Cover them with a plastic bag and store them in the refrigerator. Hardier herbs like Rosemary and Thyme can be rolled up in a damp paper towel and kept in a bag in the crisper drawer.

By using these harvesting and storing techniques, you can enjoy the taste of your hydroponically grown herbs for weeks or even months after harvesting, allowing you to savor the fruits of your labor long term.


Hydroponic herb gardening can be an incredibly rewarding endeavor. This innovative gardening method brings together the beauty of nature and the convenience of technology, enabling you to enjoy fresh herbs right at home. From setting up your hydroponic system and selecting the best herbs, to understanding the intricacies of their care and maintenance, the journey of hydroponic gardening is a continuous learning experience.

Remember, every plant in your garden has unique needs, and understanding these is key to successful growth. With keen observation and a little patience, you’ll be reaping the rewards of your indoor hydroponic garden in no time!
