9 Best Vegetables To Grow Hydroponically [Gardener’s Perspective]

Hello, hydroponic hopper! You must be wondering on the web to figure out some of the best vegetables to grow hydroponically.

Well, I did the same once and found the nine most suitable veggies and leafy greens that will be like a breeze to grow in the hydroponic systems. These veggies and greens are super convenient to grow in the system without losing their taste and natural goodness.

Before jumping into those trendy options, remember that the hydroponic system’s efficiency and the suitable variety of vegetables matter the most.

Before digging into those nine options from my experience, let’s not wait anymore and look at the benefits of growing veggies in the hydroponic garden.

What is Hydroponic Gardening?

Hydroponic gardening is a method of growing plants without soil using mineral nutrient solutions in water. These systems are often used when the soil is unavailable or one wants more precise control over the nutrients and water the plants receive.

No wonder, along with leafy green and veggies, the list of herbs for hydroponics is getting longer every day.

In this system, plants may be grown with their roots only in the mineral nutrient solution or in an inert medium, such as perlite or gravel.

Hydroponic nutrients can come from various sources, including fish excrement, duck manure, or regular nutrients.

Benefits of Growing Vegetables Hydroponically

Hydroponic vegetable farming offers several benefits, making it an attractive method for modern agriculture. Some of the key advantages include:

  • Increased Growth Rate: Plants often grow faster in hydroponic systems due to efficient nutrient uptake.
  • Higher Yields: Hydroponic farming can produce higher yields in a smaller area than traditional farming, making it an efficient method for maximizing crop production.
  • Year-Round Production: Hydroponics allows for indoor gardening, enabling year-round vegetable cultivation irrespective of outdoor weather.
  • Nutrient-Dense Produce: Hydroponically grown vegetables are often more nutrient-dense than soil-grown vegetables, providing more vitamins, minerals, and antioxidants.
  • Space Efficiency: Ideal for urban settings or places with limited space, hydroponic systems can be set up vertically.
  • Water Conservation: Hydroponic systems use significantly less water than traditional soil gardening as water is recirculated.
  • Reduced Pests and Diseases: The absence of soil reduces the risks of soil-borne pests and diseases.
  • Versatility: Hydroponic farming is versatile and can grow a wide variety of vegetables, fruits, and herbs, offering a rewarding experience for growers.

Leafy Greens

Growing spinach hydroponically is like growing lettuce but better because it helps control pests, such as leaf miners, which can be a real pain when you grow spinach in soil. Hydroponic systems reduce these issues by a lot, though not completely.

Growing spinach hydroponically indoors lets you harvest a lot of it and use it immediately or freeze it for later. It’s perfect for when you want to make a big batch of pesto and need a lot of fresh spinach.

This method of growing spinach is a great way to evade pest challenges and make sure you always have a supply of this nutrient-rich leafy green. It’s famous for its health benefits, which even Popeye knows about!

For the best results, start with fresh spinach seeds and plant multiple seeds per hole to make sure you get healthy plants in each cube.

Don’t worry. We haven’t forgotten about hydroponic basil or hydroponic cilantro despite being herbs.


Fresh green lettuce leaves with ruffled texture grow in rich soil, offering contrast to hydroponically cultivated greens.

Growing lettuce hydroponically is not only incredibly easy but also cost-effective. Consider the savings: with the average price of lettuce around $3, growing your own could save you up to $150 a year if you consume one lettuce per week.

This approach to growing lettuce is not just about the savings – it’s a simple, effective way to produce fresh, healthy greens.

Moreover, hydroponic lettuce often boasts superior quality, with reduced pest damage compared to traditional soil-grown lettuce. The key to healthy growth is adequate air circulation, typically provided by an oscillating fan.

For beginners in hydroponics, lettuce is an ideal choice due to its simplicity and rapid growth cycle, often maturing in 30 days or less. It thrives in cooler temperatures, making it perfectly suited for home hydroponic systems.

Kale, a powerhouse in the leafy greens family, finds an ideal growing environment in hydroponics.

Remember to allocate ample space for those cultivating this nutrient-rich plant hydroponically, as kale can grow quite large. Harvesting the entire plant for chopping and freezing offers a convenient way to add it to soups, stews, and smoothies.

Kale’s adaptability shines in hydroponics, thriving in various systems and boasting a wide electrical conductivity range. This allows it to be grown alongside other crops, enhancing yield and quality.

Curly Kale is particularly favored for hydroponic cultivation among the varieties due to its ease of growth and faster development.

Red tomatoes on the vine sound sophisticated, whereas some found the tomatoes in hydroponic a hoax. Like this contradiction, there’s a debate about hydroponically grown tomatoes; some argue they lack flavor, often attributed to the nutrients used during growth.

While we favor soil-grown tomatoes under the sun, hydroponic tomatoes are a fantastic option during colder months, like December in the US and Canada. Enhancing their growth with Cal-Mag can address any watery taste issues.

Choosing the suitable tomato variety for your hydroponic system is crucial. We’ve successfully grown micro varieties in an AeroGarden Sprout and determinate tomatoes in an AeroGarden Farm Plus, with rigorous pruning being the only challenge.

For those unfamiliar with tomato types, understanding the difference between determinate and indeterminate tomatoes is critical for successful hydroponic cultivation.

Growing peppers using hydroponic gardening has many advantages, especially since they belong to the “dirty dozen” category due to the use of pesticides. So, why not opt for hydroponics and enjoy fresh, pesticide-free peppers?

You can bypass stores’ high cost and limited variety, growing a broader range of peppers right at home by opting for hydroponics. Interestingly, while often cultivated as annuals, peppers are perennials in some regions, developing into tree-like structures over time.

Hydroponic or indoor cultivation with a grow light can yield a long-term, continuous supply of peppers. For example, a paprika pepper plant in a hydroponic setup can flourish for over 100 days with no signs of slowing down, as experienced in my gardening endeavors.

Plus, peppers are self-pollinating, requiring minimal fruit production intervention. However, extra care, like a gentle daily shake, can significantly boost their yield.

Green Beans

Growing green beans in a hydroponic system can be a successful and efficient endeavor, especially when selecting a suitable variety.

Opting for bush beans over pole beans is critical, as pole varieties can become overbearing and dominate the hydroponic space. Bush beans, in contrast, are more compact and well-suited for hydroponic systems.

They offer the added advantage of setting all their fruits or pods simultaneously, allowing for a substantial and timely harvest.

This characteristic makes them ideal for rotating crops in a hydroponic setup, giving you the flexibility to either replant more beans or experiment with different vegetables.

Did you know that growing cucumbers hydroponically has many benefits? For starters, hydroponic cucumbers are less susceptible to powdery mildew, a fungus that can harm traditional soil-grown cucumber plants. This means that hydroponic cucumber cultivation is more manageable and less reliant on fungicides.

Another perk of hydroponic cucumbers is their smaller root systems, making them perfect for growing in limited spaces, like urban or indoor environments. This space-efficient method allows for fresh cucumbers to be grown in areas where traditional gardening may not be possible.

Moreover, hydroponic systems offer a controlled environment that ensures optimal nutrient delivery to the cucumber plants. This results in healthier and potentially more nutrient-dense produce.

Hydroponic setups are awesome for growing fruits like cucumbers. You can control the environment by regulating nutrient levels and light cycles, which means the weather doesn’t impact the harvest much. This makes it a dependable method for getting a consistent cucumber yield.

Celery is a super hydrating veggie that’s perfect for growing hydroponically. Yup, that means you can grow Celery in a nutrient-rich solution without any soil!

And the best part? You can harvest just what you need – like a couple of stalks for your fave recipe – while the rest of the plant grows. It’s a great way to reduce waste and have fresh celery all year, even in winter.

Plus, it’s a sustainable and efficient way to grow this versatile veggie. So go ahead and add some fresh, crunchy celery to your winter recipes!


Growing beetroot hydroponically is possible, though it may not be as efficient as other plants like peppers or tomatoes. In a hydroponic system, each space is valuable, and dedicating one to beetroot means you’re growing a plant that yields a single vegetable per spot.

This might not be the most productive use of space for everyone, particularly for those who aren’t big fans of beets. However, if beets are a staple in your diet, growing them hydroponically can be a rewarding experience.
