Hydroponic Systems are a great way to grow herbs indoors.
The basic principle is you grow your herbs in a container filled with water and nutrients. An air pump is used to keep the water oxygenated & circulating around the herbs root system.
Since the nutrients are in the water, they are absorbed directly through the herb’s roots.
A hydroponic herb garden is very efficient since the roots of the herbs get both water & nutrients simultaneously in a controlled environment which results in a fast-growing, very healthy herb plant.

Who Grows Hydroponic Herbs?
The answer is more people than you think. Have you ever seen the pots of basil in the supermarkets that are stored in water? Those are grown in commercial hydroponic herb systems.
Commercial growers love using hydroponic systems since they can grow a large number of herbs in a small growing space. This maximizes their profitability. But home gardeners can also enjoy the benefits of growing hydroponic herbs.
Hydroponics systems can be used either indoors or outdoors it all depends on where you live and the space you have available.
An indoor hydroponic herb system is a great way to easily grow your favorite culinary herbs without bringing the mess of the outdoors inside.
An outdoor hydroponic garden can be equally nice – you can make it as big as you like!!!

Hydroponic Herb Garden Benefits
Here are 4 great benefits of creating your own Hydroponic Herb Garden.
1. No Messy Soil – Hydroponic Herbs are Grown in Water.
Let’s face it—dirt is just that—dirt. Most gardeners, myself included, do not mind getting their hands dirty while outside digging in the earth, planting vegetables and herbs, or enjoying their harvest.
It’s all part of the package, and we take the good with the bad—nice fresh sunshine, birds chirping in the air, dirt up to our elbows while all around our gardens are flourishing. That is just fine, and we like it that way.
However, that all changes when it comes to indoor gardening. We don’t have the same perks that we enjoy outside. When we are gardening indoors, we have to be a lot more careful since this is our home – where we eat, spend time with our loved ones & sleep.
Lots of indoor gardening happens in the kitchen, and that’s not always the best place for dirty fingernails or empty herb pots. This is what makes hydroponic systems so nice when you want to grow your own herbs indoors—no messy soil!
2. Hydroponic Herbs Grow Fast!
Hydroponic herbs can grow anywhere from 25% to 50% faster than herbs grown in conventional garden soil. The roots get fed consistently from the nutrient solution in the water. You never have to worry about over or under-watering or having your plants dry out.
Since the conditions are much more consistent in a hydroponic system, your plants will grow that much quicker. However, as with all methods of growing herbs indoors, you will still need to provide a strong light source and constant temperature for your hydroponic herbs to grow into healthy plants.
3. Year-Round Supply.
Since we are growing indoors, we don’t need to worry about the temperature fluctuations outside.
You can create your own hydroponic herb garden at any time of the year. You can start seeds in January, then enjoy a nice harvest of basil within two months. Imagine having fresh herbs in March!
4. Less Maintenance.
Once you have your hydroponic herb garden set up, the only maintenance it should require is changing the nutrient solution every 7-14 days. You don’t need to constantly check to make sure your herbs aren’t drying out or growing too big for their pot. There should be plenty of room for the roots to grow in the water reservoirs.
Unlike traditional indoor gardening, there is also very little concern over having your plants infested with fruit flies, fungus gnats, or other critters growing in the soil.
Even store-bought potting mix can be prone to insect infestation, though the hitchhikers normally come from the plants we buy in nurseries.
Hydroponically grown herbs are much less likely to fall prey to insect attacks since they are kept in a sterile environment. For many people, that is one of the best reasons to grow hydroponic herbs. It is a clean, bug-free way to grow indoors.
Types of Hydroponics Systems
There are several different types of hydroponics systems used in the home environment. Here is a basic explanation of each.
1. Deep Water Systems.
These are the most common types of hydroponics systems and are well-suited for beginners. The hydroponic herbs grow in a large reservoir of water, which is kept fresh & oxygenated by a small air pump.
2. Ebb & Flow Systems.
The ebb and flow systems keep the main water tank separate from the growing herb pots. A pump fills the pots with water and nutrients and then drains them back into the main reservoir. These units are operated by a timer that controls the pumping system.
3. Drip Systems.
These hydroponic systems keep the plant’s roots in a sterile medium. The system drip-feeds water and nutrients into the herb pots. A timer keeps the drip-feed system on a schedule, normally running for a few minutes each hour.
4. Aeroponic systems.
These systems use a misting spray to feed the roots. The roots get their water & nutrients from the mist while receiving oxygen directly from the air.
Creating your own indoor hydroponic herb garden is another way to enjoy growing your own culinary herbs. If you would like to start your own indoor culinary herb garden but don’t want to bring the mess of the outdoors inside, then growing hydroponic herbs is a perfect solution.

More Fun At-Home Herb Growing Kits
The Aquaponic Water Garden. Another fun way to grow herbs at home is in the Water Garden, a self-cleaning fish tank that grows plants. To be fair, this is not a true hydroponic system; instead, it works using aquaponics.
The water garden is a harmonious system replicating what happens in nature. The fish keep the system clean by eating the algae, and their natural waste is used to feed your plants. In turn, the plants take up the nitrates in the water, keeping it clean for the fish.
On top of the system are the plant pots and grow stones where your herbs or microgreens will grow. On the bottom is a fish tank suitable for 1 betta fish.
The Betta fish, also known as the Siamese fighting fish, do best when kept alone. Of course, they are not included in the system. You can buy them at your local pet or aquarium store.
Summary of Hydroponic Gardening
The hydroponic herb garden is a quick, no-mess solution to growing culinary herbs. Indoor hydroponic systems have become even more popular due to the growing availability of easy to use kits.
Grow your own hydroponic herbs and enjoy abundant harvests in up to half the time and space!
