Hydroponic Growing

If you’re looking to get started with growing your own microgreens, hydroponics is the way to go – and it’s easier than you might think! Hydroponic systems rely on a nutrient-rich solution being circulated through a water system in order to provide plants with the essential nutrients they need. This method of growing can save space as no soil is required, and it also saves time since there is less maintenance involved.

With hydroponics, you can control the environment better than with traditional gardening methods, allowing for more precise environmental conditions that are best suited for your chosen plants. Not only does this allow for faster growth but also a higher yield of produce than soil-based gardening methods.

Hydroponics offers many career opportunities since there is an increasing demand from consumers for locally grown produce. This form of gardening allows farmers to grow their crops year-round while providing them with smaller costs associated with energy and water consumption compared to traditional farming practices. Additionally, hydroponic systems have a lower environmental impact due to their efficient use of resources like water and land space. The lack of soil also eliminates the need for fertilizers which further reduces pollution levels in surrounding areas.

When it comes to choosing the best microgreens for your hydroponic garden, kale, arugula, and lettuce are all great options due to their high nutritional value and easy adaptability within different environments. All three plants require similar amounts of light exposure and optimal temperatures between 18°C – 25°C (65°F – 77°F).

Kale has been praised recently for its high levels of Vitamin C and dietary fiber while arugula is packed full of vitamins A & K along with anti-inflammatory properties that reduce inflammation throughout the body. Lastly, lettuce provides essential minerals like iron & magnesium which help support healthy cell growth throughout our bodies.

Since these microgreens thrive in warm climates they can be easily grown indoors or outdoors depending on where you live. When properly cared for they offer quick harvests compared to other types of vegetables so if you’re looking for something fresh from your garden without having to wait months before enjoying them, then kale, arugula or lettuce could be just what you’re looking for!

Additionally, by controlling the environment in which you grow them, such as having access to filtered water and nutrients already mixed in solution form, you know exactly what your plants are getting and when. This method of growing is also much more environmentally friendly than traditional soil-based methods because it conserves resources like water and eliminates the need for chemical fertilizers or pesticides.

When growing microgreens hydroponically, you’ll also have better control over temperature, humidity levels, and light intensity than with traditional soil-based systems. As a result, your plants will receive optimal conditions for growth which will lead to higher yields of flavorful and nutritious greens.

Plus, since these vegetables don’t require a lot of space, they can easily be grown indoors or on a balcony or patio without taking up too much room.

Since there’s no soil involved in hydroponic gardening, this also reduces the risk of disease transmission from contaminated soil or pests that may invade a garden bed outdoors. Hydroponic systems are often self-contained so there’s little chance for contamination from outside sources, making it one of the most sanitary ways to grow food at home safely.

Lastly, because nutrient solutions are already mixed according to specific instructions given by manufacturers, it’s easy to get started right away without any guesswork involved in mixing concoctions yourself.

Harvesting homegrown microgreens is an incredibly rewarding experience that allows you to enjoy fresh produce year-round while minimizing environmental impact and ensuring GMO safety! With all these benefits combined with convenience and ease of use, it’s no wonder why many urban farmers prefer growing their greens hydroponically!


You’ll love the rich flavor of kale, which is one of the most popular microgreens. Approximately 40% of all microgreens grown are kale varieties! When growing these greens hydroponically, you’ll need to provide adequate lighting indoors since natural sunlight won’t be an option. You can choose between LED lights and fluorescent bulbs; both will work well for this purpose.

Additionally, it’s important to use a soil mix with good drainage that holds moisture but doesn’t become soggy or overly damp, as this could lead to root rot. Adding perlite or vermiculite will help your soil mix retain water while providing additional oxygen for your plants’ roots.

Kale grows best in temperatures ranging from 60-75°F (15-24°C). Make sure you keep the temperature consistent throughout its growth period for optimal results. It’s also important to note that kale takes around 7-10 days longer than other microgreens to mature and reach harvestable size – so plan accordingly when starting out with this crop!

Kale prefers slightly acidic soils with a pH range between 6 and 6.5. If your pH levels are not in this range, adding lime or sulfur can help adjust them accordingly.

Kale does best when given plenty of light and kept moist at all times; however, don’t allow it to get too wet either as this can cause root rot issues down the line. To ensure its success, water kale consistently using a spray bottle or watering can – just make sure not to overdo it!

Finally, if possible incorporate some organic fertilizer into your soil mix before planting as this will give your seedlings an extra boost during their development stage. With proper care and attention given, you should have no trouble harvesting fresh kale within 2 weeks time!


Experience the peppery, flavorful taste of arugula with your next hydroponic garden! Arugula is a wonderful addition to any hydroponic garden. It’s easy to grow and requires minimal effort for successful growth.

The harvesting techniques are simple – simply cut the leaves from the stem when they reach two inches in length to enjoy their flavor. When it comes to soil preparation, you don’t need much – just use an all-purpose nutrient solution and keep the pH between 5.5 and 6.8 for best results.

Arugula has several health benefits as well. It contains Vitamin C, which can help boost your immune system; iron, which helps increase red blood cells; calcium, which strengthens bones; and magnesium, which aids in healthy muscle function. It also contains antioxidants that can help reduce inflammation and protect against free radicals. Additionally, arugula is low in calories but high in fiber content, making it an ideal choice for those looking to lose weight or maintain a healthy diet.

The best part about growing arugula hydroponically is how quickly it grows! In as little as seven days you can harvest a crop of fresh greens that are packed with flavor and nutrition. Once harvested, store them in the refrigerator for up to three weeks or freeze them if you want them to last longer than this time frame without losing their quality or flavor profile.

When it comes to adding variety to your hydroponic garden menu, arugula should be at the top of your list! Its peppery flavor will give any dish that extra sparkle while providing plenty of nutrition in every bite. Start planting today and enjoy its many benefits!


Lettuce is a great choice for growing hydroponically since it’s easy to grow and provides plenty of nutritional benefits.

Tips for Growing Microgreens Hydroponically

Hydroponic microgreens are fun and easy to grow, so don’t be intimidated – give it a try! There are several benefits associated with soil-less gardening, such as improved water quality.

When growing hydroponically, you’ll need to ensure that you have an appropriate container for your plants. You should also choose a nutrient solution specifically designed for microgreens. The solution should contain all necessary macro and micronutrients for proper growth and development.

In addition to providing adequate nutrients, you must also maintain the right pH levels in your water system. Microgreens are naturally very sensitive to pH levels, so even slight changes can have detrimental effects on their growth and health. To make sure they get the ideal environment for optimal growth, use a digital pH meter or test strips regularly.

Proper lighting is also essential when growing hydroponic microgreens because they need more light than regular crops. You can either use artificial lights or place your containers outdoors in direct sunlight during peak hours of the day. Make sure that your plants receive at least 10 hours of light per day if using artificial lighting or 8 hours of sunlight if grown outdoors.

Lastly, it’s important to keep your system clean by removing any dead foliage from time to time and replacing any parts that may become damaged over time due to wear and tear. This will help ensure healthy growth of your microgreens while keeping their flavor intact! With these tips in mind, you’ll be well on your way to successfully growing delicious hydroponic microgreens!
