How to Grow Hydroponic Herbs – Tutorial

Do you like to use just-picked herbs in the meals you cooked for your household or just yourself? I bet! These are a terrific way to bring taste and flavor to any dish you can imagine. But there’s a problem. 

In most cases, we go for those herbs just because of a few reasons. The first is that dried herbs save time. Secondly, there’s a high risk of not using them up until they expire. That’s why I started growing hydroponic herbs, which is an ideal method of culinary and herbal products!

Based on research conducted at the University of Minnesota, it’s a known fact that hydroponically grown herbs have 20-40% more aromatic oils than cultivated fields. Such a garden can provide a continuous harvest of gastronomic quality products in a relatively small space. Let me guide you and tell you everything I know about how to grow hydroponic herbs!

Before you start growing herbs hydroponically at home, you’ll need to pick the right system to start with. Here are our suggestions: 5 Hydroponic Bucket Systems with Buyer’s Guide and the 5 Grow Tent Kits with Buyer’s Guides too.

Do Hydroponic Herb Gardens Work?

Hydroponic systems are an excellent method of growing herbs indoors. The basic principle is that you cultivate your herbs in a vessel filled with water and nutrients. An air pump is used to retain hydrogen peroxide and circulate around the herbal root system. 

Since nutrients are found in water, they are absorbed directly from plant roots. A hydroponic herb garden is very effective as the roots of the herbs get water at the same time with nutrients simultaneously in a supervised environment that results in a herbaceous plant with rapid growth and very good health.

Here are proofs of why creating your own hydroponics herb garden is beneficial!

No Dirt

Much indoor gardening takes place in the kitchen, and that’s not always the best place for dirty nails or empty herbal pots. That’s what makes hydroponic systems so pleasurable when you want to grow your own herbs indoors — no dirt!

Hydroponics Grow Super Fast

Hydroponics can grow between 25% and 50% faster than grasses grown in conventional garden soil. The roots regularly feed on the nutritional solution in the water. As conditions are much more constant in a hydroponic system, this results in much more rapid growth of your plants.

Full-Year Harvest

Since you grow indoors, you don’t have to worry about temperature fluctuations out there. You can create your hydroponics herb garden any time of the year. You can start planting in January, then enjoy a nice basil harvest in less than two months!

What Are Hydroponic Herbs?

For a hydroponics herb garden, it’s crucial to find out which herbs grow in the water so that you have the best chance of luck with your garden. Let’s find out this right now!

What Herbs Grow Well in Hydroponics?

Regardless of whether you grow herbs for culinary or medicinal purposes, hydroponic cultivation is an excellent way to grow them. There’re certain reasons to do this, and the first is that they develop more rapidly. 

Besides, they come with more smell and taste than the counterparts grown in the land can. Research even shows that hydroponics have up to 40% more odorous oils. Not only that, but you may grow a range of herbs that otherwise wouldn’t grow in your area.

Although most herbs can be grown in hydroponics, as long as proper care is provided, some are more suitable for growing in water. These include coriander, melissa, mint, thyme, basil, oregano, and parsley. Mint was indeed one of the first herbs grown in hydroponics.

Can You Grow Herbs with Hydroponics?

Hydroponics is a method to leave out the soil under an opposite substance to maintain the roots of the herb and cultivate plants straight away with nutritive-rich liquid. There’re many ways to design hydroponics, but the basics are principally identical.

You need the following: 

• Freshwater. Most herbs like water with a pH of 6 to 6.5. You can set the acidity of your liquid with counter solutions that you will find in your local hardware store, garden, or hydroponic shop.
• Oxygen. Given your hydroponics configuration, you’ll either have to leave space between your plant base and the water tank, or you’ll need to oxygenate your vessel that you can carry out by buying an air stone or by installing an air pump.
• Root sustain. Even if you don’t need ground, the roots of your plant still need a little something to hold onto. Typical materials are vermiculite, perlite, peat foam, coconut fiber, and rock wool.
• Nutrition. Your plant will need a lot of Magnesium, Phosphorus, Calcium, and other nutrients to support its auspicious growing conditions and efficiency. Just as plants that grow in soil need healthy soil and fertilizer. You can either make your nutritional solution or buy blends, which is easier.
• Light. If you grow your plants indoors, you may need to invest in extra illumination.

Although there’re other elements to consider as you increase the sophistication of your hydroponics farm, the elements listed above are the most basic elements of any hydroponics system.

How Do I Make a Hydroponic Herb Garden?

I suggest you learn about my experience in setting a hydroponic herb garden.   

Step 1 – Rinse and Tape the Tank

You must spray paint on your bin if it is not already opaque to prevent algae build-up in the tank. The container must be neat before painting. Be sure to wash and dry thoroughly to make the surface smooth and dry.

The moment your container is dehydrated, take a clean pot and put it side by side with the top of the container. Mark your box underneath the net vessel – that’s the place of the waterline.

Remove a piece of adhesive from the tagging area underneath the box. After spraying the tank with paint, remove it to expose an ideal liquid level gauge.

Believe me; you’ll thank me for this quick tip. Otherwise, you’ll need to continue to open the lid to see what the level of water is, which becomes a problem when you start the herbs to grow.

Step 2 – Paint the Container 

Throw away old newsprint or paper napkins and put your box on top. Check that the top is closed. Use wide strokes with an aerosol paint box to keep the top down and all sides, except the underside with a light layer of spray coloring. 

If a completely opaque box isn’t available, take a can of painting spray. I chose a grayish color as black tends to absorb sunlight and heat the tank, too. For me, even gray was absorbing lots of heat. So, I would suggest buying white, sprinkle paint to reflect as much illumination as possible.

Wait for ten minutes and give a thicker layer on each side. You need to be certain that the least amount of light can penetrate the tank. Set it aside for 45 minutes.

Step 3 – Make the Holes

Once the paint is dry, grab your pots and line them up on the lid of your bin. Ensure that they’re spaced evenly. I needed to make room for extra jars in my garden. That is, you can certainly space yours better if you want eight jars.

After the layout is complete, begin to drill eight circular 2” holes in the X-shaped lid. Make sure you scrape up all the extra pieces of plastic. This way, you get a good even group of debris-free holes.

Perforate a hole just a little bit bigger than your 1/8″ pipe in the smaller part of your container just under the upper edge. This is going to be the airline’s “food door.” This hole must be something pierced over your liquid line; if not, you’ll get a regular leakage, so you can’t keep up appropriate water levels.

Step 4 – Set Up the Ventilation System and Supply Water 

Bring your airline over the hole you recently cut. Apply a vacuum cup to the side and underneath of your container to ensure the airline, afterward connect the stone to the inner side of the box.

If you have bought a 15-liter tank, you’ll need about 2.5 gallons of liquid to top up the tank up to the waterline. Regardless of the amount of water your tank needs, make sure you make notes. You’ll need that number down the road when you bring the nutritive mix.

Step 5 – Check pH Level and Bring Nutritious Solution

Now that you’ve constructed your tank and refilled it with liquid, you need to check the pH level of the water and bring nutrients. The majority of tap water ranges from 7.0 to 8.0. The plants you grow need water at a pH between 6.0 and 6.5, so you should use a lower pH. 

Try a couple of drops to get started. Blend it with water and try again. When the strip color corresponds to the range 6.0-6.5, it’s the right time to blend the feedstuff.

You must now recall the amount of water you added to the tank. Check out the Nutrient Blending Chart on the back label of the General Hydroponics FloraGro bottle. This will provide you with the precise amount to blend in your system. 

Step 6 – Bring the Growing Medium and Herbs

Now you have to add a little of your growth media to the bottom of every net pot. That’ll provide a bit of basic sustenance for the structure of roots while you start planting the herbs.

If you don’t start from seeds but rather choose to get a few herbaceous plants, then you’ll need to clean up your root systems from dirt. You need to start with a plant as clean as possible to avoid contaminating your tank.

Gently wash roots, dirt, taking care to minimize damage to your plant. If there’re longer roots that you can pull across the holes in the jar, go ahead! It helps the rooting system reach the water earlier and blossom in the nutrient-rich bath. Otherwise, don’t hesitate to cover the remaining root system with your cultivating medium and set the remaining pots.

End-Result

Well done! Now, you have an impressive hydroponically grown herb garden! It takes little effort in maintenance and produces all year round! After going through the planting procedure, you’ll be able to grow basil, chives, coriander, dill, mint, oregano, parsley, rosemary, thyme, and watercress, which are some of the best options! 

How Long Does It Take to Get Seedlings to Transplant Herbs to the Hydroponic System?

During transplantation, you’ll want to be careful not to induce too much of what is called “transplant shock.” When the herbs go from one surrounding to another, they’ll be slightly shocked, and it’ll take several hours to rebound. You can, however, take measures to lessen the degree to which it damages plants.

Firstly, never transfer to either warm or boiling temperatures. The seedlings are heat sensitive, and even more so during transplantation. The same goes for the temperature of the water.

Transplant when they’re prepared for watering another time. This is the moment when the medium isn’t very damp (but still moist) and won’t be spread out in the tray, which may make the plugs simpler to pull out. In other words, while you transplant, the seedlings must go straight into a system with the water running through it.

When your seeds are growing, cut all but the strongest seedlings on each start sheet. That’s it! As a rule, your seeds should germinate in 3-5 days for most greenery, and you’ll be ready to lead off cultivating awesome plants in your hydroponics system right away! 

Conclusion

This is all I have for you for today. Growing hydroponically completely changed my life. Now, I have my favorite herbs at hand in my kitchen! The thing is, I always loved gardening and, while learning new ways to cultivate something, I had made mistakes, discovered many tricks, and read many articles.

FAQ

Are Hydroponic Herbs Healthy?

It depends on the nutrient solution in which the vegetables are grown, but vegetables grown in hydroponics can be just as nutritious as those grown in the ground. Plants produce their own vitamins, such that vitamin levels tend to be similar if a vegetable is grown hydroponically or in the soil. Although this may seem counterintuitive, plants grown in hydroponics have higher yields and have a host of other benefits. 

How Do You Harvest Hydroponic Herbs?

Cut the leaves of annual plants such as basil, coriander, stevia, and dill whenever the plant is strong. Do it within just a couple of inches from the above of every stem, just above a group of leaves. You can also collect solid stems from the exterior of the herb by slicing just at the top of the basis. For plants with slow growth, such as oregano, parsley, and thyme, pick long stalks with few leaves.

What PPM for Herbs in a Hydroponic Tower

The majority of plants prefer low to medium levels of electrical conductivity (1-1.6), with the best total TDS values range from 750 ppm to 1500 PPM. But the precise volume depends on how mature your plant is and how many nutrients it can absorb. You can do more, but you can overwhelm your plants with nutrients. A mildly acidic pH of 5.5 to 6.4 is ideal. 

How Much Light Needed for Hydroponic Herbs?

In general, herbs need at least six hours of sunshine a day. If the place where you grow your grass doesn’t have access to natural light, you can replace it with man-made lighting. Buy LED or HID lights for the most effective results. You need to arrange your scheme on having a minimum of 14 to 16 hours of bright fake illumination, followed by 10 to 12 hours of darkness each day. 

What Are the Nutrients for Hydroponic Herbs? 

The nutritive supply is considered the exclusive source of nourishment and water available to the plant. Hydroponic nutrients are expected to include feedstuff, such as Magnesium, Calcium, Potassium, Phosphorous, and Nitrogen. In addition, such nutrients as Sodium, Chloride, Boron, Molybdenum, Zinc, Copper, along Iron are as well expected to be present in the content enumeration list. They can be found in soilless foodstuff solutions in varying quantities.

Can You Use Tap Water For Hydroponics?

Tap water is an accessibility solution for your hydroponics system, but it cannot be used on its own. Fortunately, tap water is easy to process, making it a precious resource to support your plants. Following the steps of the procedure, you will get a regular flow of water supply to feed your hydroponics system. But you should know the Chlorine, Chloramine, and PPM levels of your water and treat them correctly before you start.

What Is the Best Hydroponic System for Herbs?

There’s a couple of different kinds suitable for herbs of hydroponic systems that are used in the home environment. Deep Water Systems are the most common types of hydroponic systems and are well adapted to novices. Hydroponic herbs grow in a large water tank, which is maintained cool and oxygenated by a modest ventilating pump. And the second is Ebb and Flow Systems, which keep the primary water reservoir separate from growing herb pots.

What Herbs Grow Fastest?

The most fastest-growing herbs are mint, basil, and dill by their nature. But what makes an herb grow faster and with care is its size. Of course, trimming an herb means that you harvest the big leaves and tasty stems. If you don’t prune, the plant grows higher on just a few stems, and the leaves age, dry, and drop. The result is long stems that don’t have any leaves.

What Are the Easiest Herbs to Grow In Pots?

If you have little space and lack experience in growing anything hydroponically, you should start with the most simple seeds. Many useful kitchen herbs grow nicely in containers. Basil, chives, coriander, dill, fennel, garlic, melissa, mint, oregano and marjoram, parsley, rosemary, sage, French tarragon, and thyme are excellent options for enclosed farming. These herbs are necessary for any ordinary plate or just for the good smell in your kitchen. 

What Herbs Don’t Need Sunlight?

For most households, the easiest low-light indoor plants to grow are soft leaf species that reach maturity at shorter altitudes. But you should understand that growing without sunshine doesn’t imply that you can grow these herbs in total obscurity. This means that these herbs can survive the sunlight throughout the day, much better if coupled with the sunshine of the mild morning. They’re lovage, chives, sweet cicely, Corsican mint, parsley, wasabi, tarragon, angelica.
