The concept of hydroponics is really rather simple.  You grow plants without the need for soil or compost.  You provide the water and nutrients directly to the roots of the plant, cutting out the need for the soil middleman.  Providing these nutrients directly at the optimum level for plant growth and yield means that your plants grow faster, bigger and produce more.  Hydroponic systems include the nutrients, the water, and even the light needed to grow the best herbs, fruits and vegetables.

These are great hydroponics systems to grow herbs with

Growing Coriander Hydroponically

Coriander can be difficult to grow conventionally – it requires the exact right conditions – we write about them here – and that in itself makes coriander a great candidate for growing in a hydroponic system, where you have a huge amount of control over the environment. From seeding to harvesting with coriander grown hydroponically it’s about 60 days and in a hydroponic environment it’s very low maintenance, you don’t need to trim it until you’re ready to harvest.    If you’re a big user of coriander (like us), then we recommend succession planting every 6 weeks. Hydroponic coriander tastes and acts exactly the same as coriander which is grown in compost or soil.

Growing Mint Hydroponically

Mint was one of the first plants to be grown hydroponically and is very well suited to be grown in a hydroponic system.  If you’re growing mint hydroponically, it tends to have bigger and fuller foliage than mint which is grown conventionally.  When it comes to how to grow mint hydroponically, it’s easy. You can transplant it using cuttings.  Our guide to growing mint conventionally is here.   There are no special rules on harvesting mint when you’ve grown it in a hydroponic system, simply snip what you need. When you’ve grown your mint you’ll WANT to make this amazing fresh mint ice cream.

Growing Oregano Hydroponically

Oregano is part of the mint family and is a great staple in cooking.   Hydroponically Oregano grows slowly, taking about 8 weeks from transplant to harvest.  Hydroponic oregano loves full sun, so a good lighting system is key when it comes to growing oregano hydroponically.  Oregano will grow better when it’s next to basil and is also a good companion plant for both peppers and tomatoes.

Growing Thyme Hydroponically

Thyme grows extremely well in hydroponic systems.  You can propagate thyme through stem cuttings and it requires little work to grow hydroponically.

Growing Basil Hydroponically

Basil has got to be one of my favourite herbs to grow.  I have a Thai Basil plant and a Genovese Basil plant on the windowsill in front of me now, both of which I’ve grown from cuttings.  Basil is a very prolific herb and is an excellent choice for growing hydroponically.  You can trim and harvest basil weekly once the plant is mature.  Some varieties don’t need much space at all and the pH levels that Basil needs (between 5.5 and 6.5) mean that it grows well alongside other herbs. Basil is grown extensively using hydroponics for commercial purposes in Europe, where it accounts for around half of the total herb market. This kit from Click & Grow comes with Basil included – read more about it here.

Growing Dill Hydroponically

Fresh Dill with boiled or roasted potatoes is quite simply divine.  Growing your own dill hydroponically is an excellent way to have it on tap for this Moorish dish.  Dill is actually from the celery family and is pretty easy to grow hydroponically.  Hydroponic Dill can, however, grow up to 90 centimetres tall, so watch your plants!  Harvesting is easy, just cut off the leafy foliage when you need it.  Once the stems start to go brown remove them.

What other herbs can be grown hydroponically?

The following herbs are also easy to grow hydroponically – Chamomile, Lemon Balm, Marjoram and Watercress (excellent for salads!).  Fennel and Parsley grow well too, as does Tarragon.  Growing sage hydroponically is also a good option as you’re able to protect the environment of this often fragile herb. Try also anise, catnip and chervil.  Growing rosemary hydroponically is easy, but can take up to 12 weeks – we find that a rosemary bush in a pot in the garden is the best way to grow rosemary though.

What’s the Best Hydroponic System to use for Growing Herbs?

There are two different hydroponic systems for growing herbs.  We cover these in much more detail in our beginner hydroponics guide here.

  • N.F.T (Nutrient Film Technique) – this is where you put your herb plants in a pot of net so that the roots are hanging.   Your grow trays are set on an incline and the nutrient solution is pumped around continuously.
  • Ebb and Flow – gravity is used to flood the nutrient solution around the roots of the herb plant which remain submerged in growing medium and nutrient solution.

In commercial herb growing hydroponic systems, you will most often see NFT, but Ebb and Flow tends to be most commonly used by us home users.    Both are good and we discuss the pros and cons in our guide on hydroponics for beginners. If you’re just getting started, then you don’t need to worry about what system it is – all the hydroponic starter kits come with complete instructions and all the bits and pieces that you need to get started.
