6 Plants Commonly Grown Hydroponically

Hydroponics is a method of growing plants without soil. Instead, you use water with nutrients and minerals to feed the plants. Hydroponic gardening can be done indoors or outdoors, but the most common way to grow hydroponically is indoors in containers and planters using an ebb-and-flow system. 


If you want to start your own indoor hydroponic garden or learn more about how it works, here are some of the most popular hydroponic plants that people grow using the hydroponics method:


Lettuce is a cool-season crop, so it thrives in spring or fall. It can be grown indoors or outdoors but prefers to be grown in pots and containers. You can choose whether to grow lettuce plants in the ground or in water; both are equally successful.


Cucumbers are a squash family member and grow well in hydroponic gardens. The fruits can be eaten fresh or made into pickles.

Cucumbers are good sources of vitamin C and potassium, which help to prevent heart disease and high blood pressure. They also contain fiber that helps digestion, as well as phytonutrients (plant nutrients), including lutein, that may protect against certain cancers when consumed regularly.

You can harvest cucumbers at any time after they start forming fruit. They don’t all ripen at once as tomatoes do. They need plenty of water while developing their fruit. So make sure to keep them adequately watered during this stage and to check regularly for signs like yellowing leaves. It indicates fertilizer deficiency problems requiring extra nutrients added via foliar spray application, which should always include calcium/magnesium along with whatever else might be needed by these particular plants being grown hydroponically.

Tomatoes are a good choice for hydroponic gardening. They grow easily in water and don’t require soil, making them an excellent option for small spaces. Indoor tomatoes can be grown on a balcony or patio as well as indoors with the appropriate lighting. Hydroponic gardening makes it possible for more plants to grow in a small space than would ordinarily be possible with normal garden techniques. Interestingly, in traditional gardening, over watering tomato plants can lead to various issues, but hydroponics offers a controlled environment that minimizes such concerns and ensures optimal growth conditions. Tomatoes are also healthy and delicious, making them ideal for home or commercial production!


Peppers are a good choice for hydroponic gardening. They grow well in warm climates, making them suitable for all regions of the United States, and they can be grown indoors or outdoors. Peppers are easy to grow and are an excellent source of vitamins A and C.

Use your pepper plants as part of an edible landscaping project since peppers have colorful foliage that makes them perfect for ornamental gardening.

Beans and peas

Beans and peas are easy vegetables to grow in a hydroponic system. Beans can be planted in the ground or in containers, but peas need to be planted in the ground.

Peas should be planted at least two weeks before the last frost date for your area. If you live in an area with a short growing season, consider starting your peas indoors about 3 weeks before transplanting them into the garden as soon as possible. Peas will grow well on trellises if you have enough space or want to add extra height to your garden. This is especially helpful if they go next to taller hydroponic plants like tomatoes.

Spinach is easy to grow hydroponically, with a high tolerance for cold weather. Spinach is an excellent source of vitamins A and C, making it an ideal choice for home gardeners who want fresh greens all year long.

Spinach grows best in slightly acidic soil (pH 6.0–6.5) but can tolerate pH levels as low as 5.5 and as high as 6.8—making it one of the most versatile plants regarding growing conditions!


Strawberries are a great choice for hydroponics beginners. They are low-maintenance and don’t require as much care as other hydroponic plants, but they still provide plenty of delicious fruit. If you are looking for an easy way to start growing your own plants home, strawberries are a good option.

Hydroponic Gardening 

Hydroponic gardening is a method of growing plants that uses water instead of soil. Instead of relying on the nutrients found in soil, hydroponic plants are fed nutrients through the water. This makes it possible for far more plants to grow in a small space than would ordinarily be possible with normal garden techniques.

However, because they aren’t getting their nutrition from the ground as normal plants do, you will need to feed your hydroponic garden regularly so that it continues producing healthy yields. If you neglect these needs for too long, your hydroponic plant can quickly become nutrient deficient and begin starving itself—or worse yet, die altogether!

Because you need to feed your crops more often than if they were grown traditionally in soils (which sometimes means daily), this style can feel like more work than traditional gardening methods. But once you get into a rhythm with it and learn how much food each type of hydroponic plant needs (or how often), it will become just as easy as clipping off some leaves here or there every few days!


Hydroponics is a great way to grow plants without using soil and all the work that comes with it. It’s also much easier on your back! Hydroponic gardening is an ideal hobby for those who don’t have much space but still want fresh food for their family.
