Mint is renowned for its refreshing aroma and taste.

What makes mint one of the best hydroponic herbs is its year-round growth ability, ensuring a consistent supply of fresh flavour. Even in limited space, it can thrive without compromising taste or aroma. To support the growth of these excellent hydroponic plants, maintain neutral pH levels and moderate temperatures.

Care Instructions

• Experience level: Beginner friendly

7. Sage

Sage, with its soft, fragrant leaves, is next on this list.

This herb requires only modest light, so it can be grown in indoor hydroponic systems with limited illumination. However, many might worry that sage plants are larger and bushier than herbs. Yet, you can still manage them effectively in indoor hydroponic setups.

Sage generally has a more extended growth period, typically two and a half to three months. Although hydroponically growing this herb requires more time and attention than others, its rewarding taste will make your effort worthwhile.
