We're talking less mess, faster growth, and a constant supply of fresh greens. This guide breaks down exactly why this soil-free method is so effective and how you can get started.

You'll be able to cultivate a significant quantity of food without space, time, or skill level constraints. Moreover, you'll be able to do this irrespective of the surrounding climate.

This article will cover everything you need to know about growing microgreens hydroponically. We’re going to talk about what microgreens are, the benefits of growing them hydroponically, a step-by-step guide on how to grow them, the ideal hydroponic system for growing them, and other frequently asked questions about growing microgreens.

Let’s get right to it!

What are Microgreens?  

The term microgreen is used to refer to the seedlings of edible herbs and vegetables. Microgreens are harvested prior to reaching the adult growth phase.

The reason for the early harvest is that the seedlings have great texture and amazing taste. Microgreens gained popularity in the 1980s when chefs were looking for inexpensive ways to add flavor to dishes.These days microgreens are common garnishes for a lot of restaurant dishes.

What’s so special about Microgreens?

As we mentioned earlier, microgreens have amazing flavor. You get a lot of flavor in highly compact servings. Microgreens are an excellent complement to salads. Looking to add some spice to your dish? Microgreens are your answer.

Another benefit of growing microgreens is that you can grow them at any time of the year and at very little cost. Finally, microgreens can be harvested within a week to two weeks, so you can grow them repeatedly in the comfort of your home easily.

Health Benefits and a Safety Warning

Beyond their intense flavor and delicate texture, microgreens are celebrated for being incredibly nutrient-dense. Think of them as tiny, edible powerhouses. Because they are harvested just after sprouting, they contain a concentrated amount of the vitamins and minerals found in their mature counterparts. As the experts at Freight Farms explain, these tiny seedlings of vegetables and herbs are packed with nutrients, making them a simple and effective way to enrich your diet. Adding a handful to a salad, sandwich, or smoothie is an easy step toward getting more essential nutrients into your daily meals without having to eat a large volume of vegetables.

While these little greens offer a wealth of benefits, it’s also important to be aware of how they might interact with your individual health needs. Like many leafy greens, some varieties of microgreens are particularly high in certain vitamins. For most people, this is purely a good thing! However, for individuals on specific types of medication, it’s a factor worth paying attention to. Understanding the nutritional profile of what you grow allows you to enjoy your harvests safely and with complete peace of mind, ensuring your home-grown food supports your overall wellness goals.

A Note on Vitamin K for Certain Individuals

One specific nutrient to be mindful of is Vitamin K. Abundant in many leafy greens and their microgreen versions, Vitamin K plays a vital role in helping blood clot properly. For individuals taking blood-thinning medications like warfarin, maintaining a consistent level of Vitamin K is crucial for the medicine to work effectively. As one guide for growers points out, a sudden increase in Vitamin K intake can interfere with these prescriptions. This is a perfect example of why even healthy foods should be considered within the context of your personal health situation.

This doesn't mean you have to avoid microgreens entirely. Instead, the best course of action is a conversation with your doctor or a registered dietitian. A healthcare professional can offer personalized advice on how to safely incorporate microgreens into your diet without disrupting your medication. They can help you understand which varieties to choose and what portion sizes are appropriate for you. Making informed choices is the key to enjoying all the delicious and nutritional benefits your hydroponic garden has to offer.

Microgreens Ideal for Growing Hydroponically

Some of the tastiest microgreens actually flourish best if they are grown in a hydroponic setup. Kohlrabi, kale, collards, alfalfa, radishes, and clover are some of the most popular and flavorful microgreens. They are also highly nutritional.

Alfalfa, kale, radishes, and clover are particularly known for their health benefits.Any microgreen can be grown hydroponically, so there's no restriction there. Basil, carrots, and beetroots are other options you can try out.

Why Grow Microgreens Hydroponically?

Growing microgreens in a hydroponic setup have a number of advantages. Firstly, you’ll get to harvest your microgreens faster than you’d be able to if they were being grown in soil. This is because the microgreens will be getting the nutrients through direct exposure to your nutrient solution. They won't be relying on their roots to absorb nutrients through the soil.

Secondly, you can grow your microgreens anywhere in the house since you won’t need to worry about the presence of natural sunlight. Good indoor lighting or grow lights equipped with timers are more than enough to do the job. Thirdly, a lot of microgreens get the majority of the nutrients they require from the reservoir water alone (with its pH adjusted, of course).

A Little about Hydroponics

Essentially, hydroponic systems do not use soil as a medium for growing. Your grow medium is fresh water, with its pH adjusted to 6 - 6.5. Apart from that, all you need is root support (peat moss and vermiculite are good options), oxygen, grow light, and nutrients.

Benefits of Growing Microgreens in a Hydroponic Setup

Some of the obvious benefits of growing microgreens hydroponically include that you don't need soil to grow them, your setup will be water efficient, and you're not dependent on natural sunlight. You also don't have to worry about growing them outdoors. You're free from the hassle of maintaining the soil, mixing nutrients with fertilizers, or dealing with weather-related complications.

Troubleshooting is easier in hydroponic setups. This is because the number of variables involved is lesser, making it easier to identify the source of any problems. Moreover, if complications are to occur, they will occur immediately, making it possible to address them timely.

Challenges to Keep in Mind

While growing microgreens hydroponically is efficient and rewarding, it’s helpful to go in with a clear picture of the potential hurdles. Like any method of cultivation, it has its own unique set of challenges. Being aware of these from the start will help you plan better, avoid common pitfalls, and set yourself up for a successful and enjoyable growing experience. From the initial setup costs to the daily routines, let's look at a few things to keep on your radar.

High Upfront Cost

Getting started with a quality hydroponic system does require an initial investment. The equipment needed for a controlled indoor environment, such as full-spectrum LED grow lights, trays, and pumps, can add up. Depending on your space, you might also consider environmental controls like fans and monitors to maintain optimal temperature and humidity. While these tools are key to achieving consistent, high-quality harvests, the upfront capital can be a significant consideration for new growers. Think of it as an investment in a more efficient and productive system that will pay for itself over time with bountiful, soil-free greens.

Repetitive Tasks

Hydroponics simplifies many aspects of growing, but it isn’t a completely hands-off process. The system requires consistent attention and a routine to keep it running smoothly. You’ll be responsible for regularly mixing and testing the pH of your nutrient solution, cleaning the reservoir and trays between crop cycles, and managing the seeding and harvesting schedule. These repetitive tasks are crucial for preventing issues like algae growth and ensuring your microgreens get exactly what they need. For those selling their greens, managing these cycles to meet market demand requires organization and consistent effort.

Taste and Expense Considerations

The final taste and quality of your microgreens are directly linked to their growing environment. An overly damp space with poor airflow can create conditions for mold, which can affect the flavor and lead to crop loss. Using a dedicated grow tent can help you create a stable, clean environment that is easier to manage. Beyond the initial setup, you should also factor in ongoing operational costs. Electricity to run your lights and water pump is a recurring expense, as is the need to replenish supplies like seeds and growing media. Addressing these factors is key to ensuring your hydroponic system remains sustainable and productive.

How Do I Get Started Growing Microgreens?

Now let’s get into the process of growing microgreens hydroponically. We’ll start with the things you need prior to starting up.

A Step-by-Step Guide to Growing Microgreens

Step 1: Prepare Your Trays and Medium

Tray Preparation

To kick things off, you'll need to get your trays ready. The standard setup uses two 1020 trays: one with drainage holes where your growing mat will sit, and a solid one without holes to act as a water reservoir. This double-tray system is clever because it gives your microgreens consistent access to moisture from below without drowning their delicate roots. It’s a simple but effective way to prevent waterlogging while ensuring your greens get the hydration they need to grow strong and healthy.

Water Quality and pH

The quality of your water is a game-changer for healthy microgreens. You'll want to aim for a pH level between 5.5 and 6.5. Why so specific? This range is the sweet spot that allows the plants to absorb nutrients most efficiently. If the pH is off, your microgreens might struggle, even if you're providing plenty of nutrients. Regularly checking the pH of your water with a simple meter is a key habit to develop. It’s a small step that makes a big difference in your final harvest.

Step 2: Sow Your Seeds

With your trays prepped, it's time to sow your seeds. Lightly dampen your growing mat and then spread the seeds evenly across the surface. The goal is to create a single, uniform layer. Try to avoid letting the seeds clump together or pile up, as overcrowding can restrict airflow and create a welcoming environment for mold. A little bit of space ensures each seed has room to germinate and develop properly, leading to a healthier, more robust crop of microgreens.

Step 3: The Germination (Blackout) Period

After sowing, your seeds need a little time in the dark to get going. This is called the germination, or "blackout," period. Mist the seeds lightly with water and then cover the tray with a lid or another tray to completely block out any light. This darkness encourages the seeds to send down strong roots before they start reaching for light. This phase typically lasts for about three to four days. It’s a crucial waiting game that sets the foundation for vigorous growth later on.

Watering During Germination

During the blackout period, your main job is to keep the seeds consistently moist. You'll want to mist them every 8 to 12 hours. The key is to ensure the growing mat stays damp but never becomes waterlogged or flooded. Too much water can suffocate the seeds or lead to rot, while too little will stop germination in its tracks. A fine mist is all you need to maintain that perfect level of moisture and give your seeds the ideal conditions to sprout.

Step 4: Introduce Light and Nutrients

Once your sprouts are about half an inch tall, they're ready for the spotlight. Remove the cover and place the tray under a light source. For consistent results, LED grow lights are fantastic, providing 12 to 16 hours of light each day. At this stage, you can also start feeding your microgreens. Since your growing medium is inert, it doesn't contain any food for the plants. Add a very diluted hydroponic nutrient solution to the water in your reservoir tray. This will give your greens the fuel they need to develop their vibrant color and rich flavor.

What Do I Need Before I Can Start Growing Microgreens?

Firstly, if you don't already have one, you'll need a hydroponic setup. If you have the money, you can definitely install high-end hydroponic setups, but it isn’t essential. You’ll need fresh water to begin. It is essential that your water is pH-balanced and has adequate phosphorous, magnesium, and calcium.

Oxygen is also a must, for which a good air pump and air stone will suffice. The next step is finding root support. Since we aren’t using soil, we need to get hydroponic grow media. Rockwool and coco coir are good options. It's important not to use media that absorb moisture, such as sand or gravel.

Now you’ll need your light sources. Microgreens do not require intense lighting, so you don’t have to invest in expensive grow lights. A simple grow light with a timer is more than sufficient. Fluorescents and small LED grow lights are also excellent options.

Choosing Your Grow Medium

In a hydroponic system, your main growing medium is pH-balanced water filled with nutrients. However, your microgreens still need something to anchor their roots to as they grow. This is where a physical growing medium comes in. You have several great soil-free options to choose from, each with its own benefits. Materials like coco coir, peat moss, or vermiculite are fantastic choices because they hold moisture well without becoming waterlogged, giving roots the perfect balance of water and oxygen. The goal is to find a sterile, inert material that provides structural support and allows the nutrient solution to flow freely to the developing plants, setting them up for healthy, rapid growth.

Disposable vs. Reusable Mats

When it comes to providing that root support, grow mats are one of the easiest solutions. You can generally choose between disposable or reusable options. Disposable mats, often made from materials like hemp or felt, are incredibly convenient. After you harvest your microgreens, the roots remain tangled in the mat, so you can simply compost the entire thing. This makes cleanup a breeze and ensures a sterile environment for your next batch. Reusable mats, typically made from food-grade plastic or silicone, are a more sustainable and cost-effective choice in the long run. They just require a thorough cleaning and sanitizing between uses to prevent any potential mold or bacteria from affecting your next crop.

DIY Setup Options

You don’t need a fancy, expensive system to get started with hydroponic microgreens. A simple do-it-yourself setup can work just as well, especially when you're just starting out. You can easily repurpose shallow containers you already have at home, like takeout containers or small plastic bins. The key is to have two nesting trays: one with small holes for drainage where you'll place your grow mat and seeds, and a second solid tray below to act as a reservoir for the water and nutrient solution. While the container can be simple, you'll still want to provide your greens with quality LED grow lights to ensure they grow strong and healthy, rather than becoming leggy from searching for light.

Seeds vs. Cuttings

One of the unique benefits of microgreens is that they will regrow many times after you cut them. This means that you can harvest a single set of seeds multiple times. If this is the first time you’re growing microgreens in a hydroponic setup, it’s easier if you start with seeds. The cuttings can be used again for growing additional batches.

Two things to keep in mind here. Firstly, it's important to leave some stems every time you take a cut. Secondly, subsequent harvests will have lesser flavor compared to the initial batch.

Care Tips for Hydroponic Microgreens

There are a couple of things that you need to ensure on a daily basis.

• You need to make sure that your microgreens have adequate water and light. Light exposure needs to be balanced with exposure to darkness as well. Plants, in general, require the dark as well as light.
• It’s good practice to check on your microgreens twice a day at twelve-hour intervals. Wilting indicates that your plants are getting less than adequate water. Rotting indicates the opposite, i.e., too much water.
• Check the pH of your water consistently.
• Check your trays for mold consistently.
• Check the depth at which you’re planting your seeds. Read the instructions that come with your seeds for this.

Common Problems and Specific Solutions

Even with a process as streamlined as hydroponics, you might run into a few hiccups. Don't worry—most common issues are easy to fix with a few small adjustments. The key is knowing what to look for so you can act quickly. From fuzzy mold to lanky-looking stems, being prepared will help you keep your microgreens healthy and thriving. Think of it less as troubleshooting and more as fine-tuning your setup for the perfect harvest. With the right approach, you can handle these minor challenges and get right back to watching your greens grow.

Preventing Mold with Good Airflow

One of the most common sights in a new microgreen tray is a bit of fuzzy, white growth that looks suspiciously like mold. This often happens because of high humidity and dense planting, creating the perfect environment for it to appear. The best way to handle this is through prevention. As one expert guide notes, you should "ensure good airflow and do not overwater." A small, oscillating fan placed near your trays can work wonders by keeping the air moving. This simple step helps dry the surface of your growing media and makes it much harder for mold to take hold. Proper environmental controls are your best defense against this common issue.

Preventing "Leggy" Plants with Proper Lighting

Have you ever noticed your seedlings looking long, pale, and stretched out? This is a condition known as being "leggy," and it happens when your microgreens aren't getting enough light. They are literally stretching themselves thin trying to reach for a stronger light source. This results in weak, flimsy stems that are likely to fall over. The fix is straightforward: give them better light. "Using T5 or LED grow lights prevents 'leggy' (weak/stretched) plants." Make sure your light source is positioned just a few inches above the canopy of your greens and is on for about 12-16 hours a day to encourage strong, compact growth.

Growing in Hot Weather

While indoor growing protects you from many weather-related issues, high temperatures can still affect your delicate microgreens, causing them to wilt or grow poorly. The beauty of an indoor setup is the control it gives you. You can "grow leafy greens all year, even in hot weather... by growing them indoors with lights and air conditioning." If your grow space gets warm, use fans to circulate air and consider venting hot air out of the room. Using a dedicated grow tent can make managing the temperature much easier, creating a stable environment where your microgreens can flourish regardless of the season outside.

Pest Control in Hydroponic Setups

One of the big advantages of hydroponics is the absence of soil, which eliminates many common pests. However, you're not completely in the clear. Fungus gnats can still be attracted to the moisture in your grow mats. The most effective strategy here is maintaining a spotless growing area. A clean space is your first line of defense, as "a clean growing area helps prevent pests and diseases like mold." Always start with sterilized trays and fresh water. By keeping things tidy and removing any dead plant matter promptly, you create an environment where pests simply don't want to be, allowing your microgreens to grow undisturbed.

Harvesting and Post-Harvest Information

After watching your microgreens sprout and grow, you finally get to the most rewarding part: harvest time. This is where your patience pays off in the form of fresh, flavorful greens. Knowing exactly when and how to harvest is key to getting the best taste and texture from your crop. It’s a simple process, but a little technique goes a long way. You’ll also want to know how to handle your greens after cutting to keep them fresh and whether you can expect a second round of growth from your tray.

When and How to Harvest

Timing is everything when it comes to harvesting microgreens for peak flavor. Generally, "they are ready to harvest after 10-12 days total." You'll know they're ready when they've developed their first set of true leaves, which look different from the initial two cotyledon leaves that first sprouted. To harvest, grab a pair of sharp, clean scissors or a knife. "Cut them close to the mat with a sharp knife or scissors." A clean cut helps prevent damage to the remaining stems if you're hoping for a second harvest and ensures your harvested greens look neat and tidy.

Flavor and Regrowth

One of the great things about growing microgreens is the potential for multiple harvests from a single sowing. To encourage regrowth, "it's important to leave some stems every time you take a cut." By cutting about half an inch above the grow mat, you leave enough of the plant to sprout again. Keep in mind that while you can get a second or even third harvest, "subsequent harvests will have lesser flavor compared to the initial batch." For a continuous supply of the most flavorful greens, it’s a good idea to start a new tray every week or so.

Alternative Growing Methods and Tips

Once you've mastered the art of growing microgreens, you might be curious about what else you can do with your setup. The skills and equipment you're using are versatile, and there are simple ways to switch things up. Whether you want to experiment with different flavors and textures or just get more out of your seeds, a small tweak in your process can open up new possibilities. It’s all about having fun with your indoor garden and tailoring it to your tastes.

From Microgreens to "Baby Greens"

If you find that the intense flavor of microgreens isn't quite for you, or if you simply forget to harvest a tray on time, you have a great alternative. "If you don't like microgreens, you can still grow 'baby greens' from the same seeds." The process is nearly identical. "Baby greens are just microgreens allowed to grow a little longer until they have their first 'true' leaves." By letting them mature for another week or two, you'll get larger, milder leaves that are perfect for salads. You may need to introduce a diluted nutrient solution to support this extended growth, but it’s an easy way to produce another type of delicious green from the very same seeds.

Hydroponic Systems is best for Growing Microgreens

If you’re looking to just add to your cooking essentials for home, you can do with a basic hydroponic setup, as detailed above. Or you could opt for a hydroponic micro-garden, which we’ve talked about below.

However, if you’re growing commercially, the ideal choice for you would be a flood and drain setup. We have excellent options for those!

Also, check out our recommendations for the best hydroponic systems for the year!

Hydroponic Micro-gardens

If you’re looking to grow microgreens for home purposes, your best option would be a hydroponic micro-garden. Micro-gardens are small-scale hydroponic systems specifically designed for small plants like microgreens.

One option is the SunBlaster Grow Light Gardens. These come in six different sizes, depending on the quantity you want to grow. One of the best features is that they come with a grow light as well! So all you’d need to get is an appropriate nutrient package and pH-balanced water. The micro-garden is fully automated and uses a wick for feeding nutrients to the plants.

The SunBlaster is small enough to be placed on your kitchen counter or even a small desk. Just select your seeds, assemble the system and enjoy the fruits of your labor (well, microgreens in this case)!

Another excellent option is the Hydrofarm MegaGarden. If you opt for this, you'll have to get a light source separately or place the system near a source of natural sunlight.

Ebb & Flow Systems

If you want to grow microgreens on a commercial scale, an ebb-and-flow hydroponic system is a worthwhile investment for you. Ebb and flow systems are also called flood and drain systems. In the ebb and flow systems, you have a grow stand and tray, a water reservoir, an air pump, a water pump, and grow media.

Here at GroIndoor.com, we have a range of ebb and flow systems. One of these is the Sananbio Radix S-Vertical grow kit. The system is built in racks, which means you can maximize the use of your grow space. Also, each rack has LED lights, so you won’t have to worry about getting a separate light source.

Alternatively, you could consider the Botanicare and Active Aqua systems which are more price-friendly options.

FAQs

These are some of the most commonly asked questions about growing microgreens hydroponically.

Can Microgreens Regrow after you Take Cuttings?

Most microgreens do regrow once you’ve taken cuttings. As we mentioned earlier, this is one of the benefits of growing microgreens. Just leave some stems when you're taking cuttings. Remember, the subsequent harvest won't be as tasteful as the first!

Do Microgreens Require Fertilizer if Grown Hydroponically?

No, they do not. All the nutritional requirements for your plants are provided by the nutrient feed.

Is Growing Microgreens Hydroponically more Beneficial?

We believe that there are far more benefits to growing microgreens in a hydroponic setup compared to a conventional soil garden. This is particularly true if you're located in an urban area.

If you’re located in a rural area and can’t afford the initial cost of setting up a hydroponic system, then you can grow them in soil.

Are Microgreens really Good for Health?

Yes, microgreens have a lot of health benefits. As mentioned above, alfalfa, kale, radishes, and clover, in particular, have a lot of health benefits.

How long do I Need to provide Microgreens with Light during the Day?

This can vary depending on the microgreens you are growing. As a rule of thumb, they should have light for 12 hours during the day.

Is it Possible for Microgreens to Grow into Adult Plants?

It is, but then they’ll be full-fledged adult plants, not microgreens. If you’re aiming to do that, then you’ll have to adjust your growing space and nutrients accordingly.

Other Commercial Systems

While Ebb & Flow systems are fantastic for commercial microgreen production, they aren't the only players in the game. Depending on your space and goals, a couple of other popular hydroponic methods are worth considering. For commercial hydroponics, systems like Nutrient Film Technique (NFT) are popular for their efficiency in nutrient delivery and water usage. Another highly effective method is Deep Water Culture (DWC), which is known for its simplicity and rapid growth rates. Both offer unique advantages for cultivating high-quality microgreens at scale, giving you more options to find the perfect fit for your operation.

Nutrient Film Technique (NFT)

Nutrient Film Technique, or NFT, is a system where a very shallow stream of water containing dissolved nutrients recirculates past the bare roots of plants in a watertight channel. Instead of being fully submerged, the roots get a constant, thin film of nutrient solution. This design ensures the roots receive plenty of oxygen from the surrounding air while still having direct access to water and nutrients. It’s an incredibly water-efficient method and is especially well-suited for lightweight, fast-growing plants like lettuce, herbs, and, of course, microgreens. The continuous flow helps prevent nutrient stagnation and keeps the root zone healthy.

Deep Water Culture (DWC)

Deep Water Culture (DWC) systems are another excellent choice for commercial growing. In a DWC setup, plants grow with their roots submerged directly in a nutrient-rich, oxygenated water solution. An air pump and air stone are used to continuously supply oxygen to the reservoir, which is crucial for preventing root rot and promoting healthy growth. This constant supply of nutrients and oxygen allows for incredibly fast development. DWC is relatively simple to set up and maintain, making it a great entry point for commercial growers who want a reliable system without too much complexity.

Financial and Cost-Saving Information

Growing your own microgreens isn't just a rewarding hobby; it can also be a smart financial move. Whether you're looking to supplement your income or simply cut down on your grocery bill, hydroponic microgreens offer a great return on your investment. The startup costs can be quite low, especially if you get creative with your initial setup, and the potential earnings from selling fresh microgreens can be surprisingly high. Plus, by buying supplies wisely and starting with some DIY solutions, you can make the entire process even more affordable and accessible, no matter your budget.

Market Value and Potential Earnings

If you're thinking about turning your green thumb into a side business, microgreens are a great place to start. They have a high market value and are always in demand by local chefs, farmers' markets, and health-conscious consumers. The numbers can be quite impressive; just one standard growing tray of microgreens can produce two to three pounds, which could earn you anywhere from $64 to $144. By maintaining a regular growing cycle, you could potentially generate over $300 in extra income each month. It's a fantastic way to make your hobby pay for itself and then some.

Saving Money on Seeds and Supplies

Getting started with hydroponic microgreens doesn't require a huge initial investment. There are plenty of ways to keep costs down while you're learning the ropes. From buying seeds in bulk to repurposing common household items for your initial setup, a little resourcefulness goes a long way. As you gain experience and decide to scale up, you can then invest in more specialized equipment. But for now, let's focus on how you can begin your microgreen journey without breaking the bank.

Buying Seeds in Bulk

One of the easiest ways to save money is to purchase your microgreen seeds in bulk. It's much cheaper to buy seeds from specialized suppliers rather than in small packets from regular stores. For example, buying broccoli seeds in bulk might cost around $25 for a supply that yields about 100 servings, which breaks down to just 25 cents per serving. This simple switch can significantly reduce your ongoing costs, whether you're growing for personal use or for sale. Look for reputable suppliers that offer a wide variety of high-quality seeds to get the best value.

DIY Cost Savings

You don't need a fancy, expensive system to start growing microgreens. You can begin with simple, everyday items you probably already have at home. Using things like takeout containers or small plastic bins can help you start your seeds without any significant investment. This DIY approach allows you to experiment and learn the process on a small scale. Once you're consistently producing successful harvests and are ready to expand, you can upgrade to professional-grade growing trays and systems to increase your yield and efficiency.
