Hydroponic gardening has become increasingly popular amongst savvy gardeners, especially those living in city environments or those with limited outdoor space. The opportunity to grow fresh and healthy herbs indoors all year round is too attractive to ignore. The choice of herbs that can be grown hydroponically is vast, but some are more well-suited to this gardening style than others. Let’s explore the top hydroponic herbs for your indoor garden and why they thrive in such conditions.
Starting with Basil, this is undoubtedly one of the most popular herbs grown in hydroponic systems. Basil, especially sweet Italian and Thai varieties, grows exceptionally well in this setup and often outperforms soil-grown equivalents in terms of yield and flavor. Unlike soil, hydroponics allows precise control of nutrient delivery, allowing basil to reach its full potential. Basil prefers a pH of between six and seven, temperatures between 70-80 °F, and significant light exposure, ideally 10-12 hours per day.
Next on the list is Chives. This herb’s delicate onion-like flavor is an excellent addition to many dishes, and its beautiful purple flowers also make an attractive addition to your indoor garden. Chives, like most herbs, prefer a sunny location, and a pH slightly acidic to neutral (6.0-7.0). The best temperature range for chives is between 60 and 75 °F. Their shallow roots make them ideal for hydroponic growing, particularly in the nutrient film technique (NFT) system.
Dill, with its delicate fern-like leaves and robust flavor profile, is also highly suited to hydroponic cultivation. Being a fast grower, it is ideal for beginners starting in hydroponics. It grows well during the cooler months and prefers an environment with the temperature around 60 to 70 °F, a pH level between 6.0 – 7.5, and 12-14 hours of light daily.
Mint, a prolific grower which can be a problem in traditional gardens, finds its perfect match in a controlled hydroponic environment. It prefers high humidity and a light-intense environment, both easily achievable indoors. With an ideal pH environment of 7.0, temperature around 70-75 °F, and requiring 10-12 hours of light daily, Mint can truly proliferate in your hydroponic garden.
Parsley, particularly the flat-leaf Italian variety which is more flavorful than its curly counterpart, is another herb that promises impressive results when grown hydroponically. Parsley is relatively easy to grow, preferring a neutral pH of 6.0 – 7.0, temperatures of 70-80°F, and 12 hours of light per day.
Next herb deserving mention is Oregano. This perennial plant is often used fresh or dried in a number of Italian and Greek dishes. Preferring a slightly acidic pH level between 6.0 – 7.0, a temperature range of 65-75 °F, and 6-8 hours of light daily, Oregano is well-adapted for a hydroponic system.
Cilantro, also known as coriander, can be a little tricky to grow hydroponically due to its bolt-quick nature, but with careful monitoring of lighting and temperature conditions, it can be successfully grown in an indoor garden. Provide an environment of 70-85°F, pH range of 6.5–7.5, and 4-6 hours of sunlight to achieve the best results.
Thyme is the quintessential herb for any indoor hydroponic garden. Thyme thrives best in a hydroponic garden when the temperature is held steady between 50 and 85 degrees F, the pH levels are kept between 6 and 8, and it receives at least eight hours of full sun daily.
Lastly, Rosemary, a woody perennial that’s as ornamental as it is flavorful, grows outstandingly well hydroponically. An environment with a temperature of 50-85°F, pH level between six and seven, and 6-8 hours of light each day can yield a robust Rosemary plant.
Now, you’ve got a definitive guide to the best hydroponic herbs to grow in your indoor garden. Ensure your herbs receive the appropriate nutrient ratio, plenty of light, and within the right temperature and pH range for each herb. With this guide, you are well on your way to becoming an expert hydroponic herb gardener.
