🌿18 Plants You Can Grow Year-Round Hydroponically
Honestly, I’m surprised more people don’t grow food indoors. Growing food hydroponically lets you harvest fresh produce year-round and cut entire categories out of your grocery bill. If I can inspire even a handful of people to start, I’ll consider that a win.
A good hydroponic system—like an AeroGarden or Rise Garden—can feel like an investment upfront, but it pays for itself over time. Between the savings, convenience, and food quality, it’s one of the easiest ways to become more self-sufficient. If you handy and love a good DIY then you can totally build your own hydroponic system (I’m working on a couple myself and will share soon).

If you want fresh herbs, leafy greens, and even vegetables year-round, the good news is that many plants thrive in hydroponic systems. This makes it possible to harvest homegrown produce regardless of the season. Whether you're using an AeroGarden, Click & Grow, Rise Garden or another hydroponic garden, choosing the right plants can make all the difference. Some crops grow quickly with very little maintenance, while others can be a bit more tricky..
In this post, we will look at 18 plants that you can grow hydroponically year-round, including beginner-friendly herbs, productive leafy greens, and high-yield fruiting crops. For each plant, you'll learn why it performs well in hydroponics, its light and nutrient requirements, common challenges, and practical tips to help you succeed. It doesn’t matter if you're just getting started with hydroponics or looking to expand your indoor garden, these plants can help you maximize your harvests and enjoy fresh food every month of the year.
For every plant I have given a “Best System” recommendation, this is not meant to imply that you can’t grow them in another system. You sure can, these are just my suggestions for how I have best been able to grow them. But use what you have and grow what you want, because you won’t know until you try. I have also added a rating for each plant, so if you are a total newb you can use this as a guide in terms of which ones to try first. Or if you just want to jump in with both feet then follow your heart and grow whichever ones speak to you.
🌱 Hydroponic Difficulty Rating
🟢 Beginner-Friendly
Easy to grow, forgiving of mistakes, grows reliably in most hydroponic systems.
🟡 Intermediate
Requires a bit more attention to lighting, nutrients, temperature, or harvesting techniques.
🔴 Advanced
Less forgiving, longer growing cycle, higher nutrient demands, pollination requirements, or space challenges.
🥬 Lettuce
🌱 Why grow lettuce hydroponically?
Lettuce is one of the most reliable hydroponic crops because it grows quickly, stays in a continuous leafy growth cycle, and does not require flowering or pollination. In hydroponics, it produces tender, clean leaves with fast turnaround times and minimal space requirements. Honestly, I prefer lettuce grown hydroponically to outdoors, as an added bonus it frees up space in my outdoor garden for crops that are harder to grow indoors. Compared to soil growing, hydroponic lettuce is more consistent, grows faster, and is less affected by pests or environmental fluctuations.

💡Pro tip: Keep roots cool and stagger plantings every 1–2 weeks for continuous harvests.
🥬 Spinach
🌱 Why grow spinach hydroponically?
Spinach grows quickly and produces tender leaves when environmental conditions remain cool and stable, which is much easier to control when growing indoors. Plus, any time I have tried to grow it outside the leaf miners seems to feast on it before I can! Rather than grow this a bit at a time, I like to grow a big batch of it (think CG25 but planted ALL at the same time) and then harvest it all at once, chop it, and freeze in using super cubes. This saves me buying the pre-frozen cubes to use in a delicious batch of Italian Wedding Soup!

🍅 Tomatoes
🌱 Why grow tomatoes hydroponically?
Tomatoes are one of the most popular and high-yielding hydroponic crops because they respond extremely well to consistent water and nutrient delivery. In hydroponic systems, tomatoes grow faster, produce more reliably, and are less affected by soil-borne diseases.
With the right setup, a single plant can produce an impressive continuous harvest over several months, making tomatoes one of the most rewarding crops for indoor hydroponic gardeners. I am not a fan of the red or yellow “heirloom” pods that come with many AeroGardens. I find they grow far too large and unruly for most systems. You are better served by sourcing out a true dwarf variety (check our The Dwarf Tomato Project) or even better a micro dwarf variety so that you can grow tomatoes in ANY system…even in an AeroGarden Sprout. My go to source for micro dwarfs is from my girl Ash at MoonGlow Seeds.
My suggestion is to stick with:

🍓 Strawberries
🌱 Why grow strawberries hydroponically?
Strawberries are a rewarding, though sometimes frustrating fruiting crops for hydroponic systems because they produce sweet, continuous harvests in a compact space but can be prone to pest issues. In hydroponics, strawberries benefit from consistent access to water and nutrients, which supports steady flowering and fruit development throughout their growing cycle.
Compared to soil growing, hydroponic strawberries are often cleaner, less prone to pests and rot, and can be grown vertically—making them ideal for small indoor spaces and year-round production.
I love to grow alpine strawberries due to their lack of runners. The berries are MUCH smaller than regular strawberries but what they lack in size they more than make up in flavour! If you do grow everbearing varieties you will need to keep the runners under control OR you can have little pots with some soil on the grow deck to anchor the runners into. Then you can move them to your outdoor garden, making it a win-win scenario.

Radishes do not regrow after harvest, so successive planting is recommended for a continuous supply.
⚠️ Common problems
Small or woody roots from inconsistent growing conditions
Excess leafy growth due to high nitrogen levels
Cracked or split roots from irregular nutrient or water availability
Poor root formation in overly deep or poorly oxygenated systems
Most issues are related to nutrient balance rather than plant difficulty.
Pro tip: Sow 4–6 radish seeds per pod to boost yield.
Beets
🌱 Why grow beets hydroponically?
Beets can be grown hydroponically for both their roots and their leafy greens, making them a dual-purpose crop. While they are slower and more challenging than leafy greens, they can still produce steady growth in a controlled hydroponic system with consistent nutrients and enough root space.
In hydroponics, beets are often grown more successfully for their tender, nutritious greens than for large root development, though full roots are still possible with the right setup. If you don’t like the earthy flavour of beets but want to try them because you KNOW they are good for you. Then check out the Badger Flame beets from Row7Seeds, they were bred (NOT GMO) to have less earthiness.

Beets are slower than most hydroponic crops, especially when grown for full root development.
✂️ Harvest method
Beets can be harvested in two ways:
For greens: Harvest outer leaves continuously while allowing the plant to regrow
For roots: Harvest the entire plant once the beet reaches desired size
Once the root is harvested, the plant does not regrow.
⚠️ Common problems
Small root size due to limited space or shallow systems
Excess leafy growth with insufficient root development
Slow growth compared to leafy greens
Poor bulb formation in high-nitrogen conditions
Beets require more patience and system optimization than most leafy crops.
💡 Pro tip: Grow for greens rather than large beets indoors or sow 3-4 seeds per pod for a bigger harvest.
🌿 Celery
🌱 Why grow celery hydroponically?
Celery is a slow-growing but highly rewarding crop in hydroponic systems. It thrives in consistent moisture conditions and benefits from the stable nutrient delivery that hydroponics provides. While celery takes longer to mature than most leafy greens, it produces crisp, flavorful stalks that are often more tender when grown hydroponically compared to soil.
Hydroponic celery is especially useful for gardeners who want a steady, long-term crop rather than fast turnover greens. Considering that celery is about 95% water it is well suited to be grown hydroponically.

🟡 Intermediate
💡 Light requirements
Celery grows best with 12–16 hours of light per day.
Moderate light is sufficient, but consistent lighting helps prevent weak, stringy stalks and supports steady growth over its long cycle.
🧪 Nutrient needs
Celery is a moderate feeder and benefits from a balanced nutrient solution.
It requires:
Consistent nitrogen for stalk and leaf growth
Calcium for structural strength
Steady moisture and nutrients to prevent stress
Fluctuations in nutrients or water levels can significantly slow growth.
⚖️ Ideal pH range
6.0–6.5
🌿 Growth timeline
Germination: 10–21 days
Seedling stage: 3–5 weeks
Harvest (baby stalks): 6–8 weeks
Full maturity: 10–16+ weeks
Continuous production: Several weeks with outer stalk harvesting
Celery is one of the slower crops in hydroponics but offers long harvest potential.
✂️ Harvest method
Celery can be harvested in two ways:
Outer stalk harvesting: Remove outer stalks as needed while the plant continues growing
Whole plant harvest: Cut at the base once fully mature
Outer harvesting allows for extended production over time.
⚠️ Common problems
Slow or uneven germination
Stringy stalks from inconsistent light
Tip burn caused by calcium imbalance
Stunted growth in unstable nutrient conditions
Celery is sensitive to environmental fluctuations and rewards consistency.
💡 Pro tip: Patience is key—celery rewards long-term growers.
🌱 Peas
🌱 Why grow peas hydroponically?
Peas are a cool-season, vining crop that performs well in hydroponic systems when given vertical support and stable growing conditions. They produce sweet, edible pods and can offer a satisfying harvest over several weeks once established.
In hydroponics, peas benefit from consistent moisture and nutrient delivery, which supports steady flowering and pod formation. They are especially rewarding for growers who want a productive crop that also adds vertical interest to an indoor garden.
I do not, I repeat I DO NOT suggest growing “normal” peas, they get out of control fast, even with trellising. I prefer to grow dwarf varieties such as Tom Thumb peas which are very compact but still give nice pods.

🟡 Intermediate
💡 Light requirements
Peas grow best with 12–14 hours of light per day.
They prefer moderate light and cooler conditions. Excess heat or very intense lighting can reduce flowering and overall pod production.
🧪 Nutrient needs
Peas are a moderate feeder and generally require a balanced nutrient solution.
They benefit from:
Moderate nitrogen for early vegetative growth
Stable potassium levels for pod development
Consistent nutrients without large fluctuations
Avoid overfeeding nitrogen, which can encourage leafy growth at the expense of pods.
⚖️ Ideal pH range
6.0–7.0
🌿 Growth timeline
Germination: 7–14 days
Vegetative growth: 3–5 weeks
Flowering begins: 5–7 weeks
First harvest: 6–8 weeks
Continuous harvest: Several weeks
Peas tend to produce in a concentrated harvest window once flowering begins.
✂️ Harvest method
Harvest pods when they are plump, firm, and still tender.
Frequent picking encourages continued pod production. Leaving mature pods on the vine can slow down further yields.
⚠️ Common problems
Poor flowering in warm conditions
Weak vines without adequate support
Reduced yields from overcrowding
Short production window compared to leafy greens
Peas perform best in cooler, stable environments.
💡 Pro tip: Provide trellis support early for best production.
🌿 Mustard Greens
🌱 Why grow mustard greens hydroponically?
Mustard greens are a fast-growing, nutrient-dense leafy green that performs very well in hydroponic systems. They produce tender young leaves quickly and can be harvested repeatedly, making them a strong option for year-round indoor production.
In hydroponics, mustard greens tend to grow faster and more uniformly than in soil, with cleaner leaves and fewer pest issues. They’re also highly productive in small spaces, which makes them ideal for compact indoor gardens.

💡 Light requirements
Mustard greens grow best with 12–16 hours of light per day.
Moderate light is sufficient, but stronger light produces faster growth and more vibrant leaf color. Insufficient light can lead to slower growth and weaker flavor.
🧪 Nutrient needs
Mustard greens are a light to moderate feeder and thrive in a balanced hydroponic nutrient solution.
They benefit from:
Consistent nitrogen for leafy growth
Adequate calcium for leaf structure
Stable nutrient levels to avoid stress
They are generally less demanding than fruiting crops.
⚖️ Ideal pH range
6.0–7.0
🌿 Growth timeline
Germination: 3–7 days
Baby leaf harvest: 2–3 weeks
Mature harvest: 4–6 weeks
Continuous production: Several weeks with cut-and-come-again harvesting
Mustard greens are one of the quicker leafy greens for hydroponic systems.
✂️ Harvest method
Harvest using a cut-and-come-again approach by removing outer leaves while allowing the center of the plant to continue growing.
Alternatively, harvest the full plant once it reaches maturity if you prefer larger quantities at once.
⚠️ Common problems
Bolting in warm conditions
Bitter flavor when plants are heat-stressed
Overcrowding reducing airflow and leaf quality
Uneven growth in low-light conditions
Mustard greens perform best in cool, stable environments.
💡 Pro tip: For best flavor, harvest while leaves are still young and tender. Succession planting every 1–2 weeks helps maintain a continuous supply.
Final Thoughts on Growing Hydroponically Year-Round
One of the biggest advantages of hydroponic gardening is the ability to grow fresh food year-round, regardless of outdoor weather conditions (either too hot or too cold). By choosing plants that are well-suited to hydroponic systems, you can enjoy a steady supply of herbs, leafy greens, vegetables, and even fruit from the comfort of your home.
If you're new to hydroponics, start with easy crops like lettuce or basil. These plants grow quickly, require minimal maintenance, and help build confidence as you learn the basics of managing nutrients, lighting, and water quality. As your experience grows, you can expand into more demanding crops like tomatoes, peppers, cucumbers, strawberries, and eggplant.
Remember that success in hydroponics comes down to providing the right balance of light, nutrients, oxygen, and consistent care. Even small adjustments can have a significant impact on plant growth and productivity.
Start small, experiment often, and don’t be afraid to push the limits. You might be surprised at what you can grow—and what you can stop buying.
