The Best Hydroponic Plants for Beginners
When starting with hydroponics, the thought of growing plants without soil can feel a bit intimidating. But here’s the secret: it’s not as complicated as it seems, especially when you start with beginner friendly plants. Some plants are just easier to grow hydroponically than others, and choosing the right ones can set you up for success. In this guide, I’ll walk you through the best hydroponic plants for beginners, so you can grow with confidence and enjoy fresh, home-grown produce in no time!
1. Leafy Greens
If there’s one category of plants that loves hydroponics, it’s leafy greens. They grow quickly, require minimal maintenance, and thrive in the controlled environment of a hydroponic system.
- Lettuce – Lettuce is often the go-to for beginners because it’s fast-growing and can be harvested continuously. You’ll have fresh salads ready to pick within a few weeks!
- Spinach – Another fantastic choice, spinach thrives in cooler conditions and grows well with basic hydroponic systems.
- Kale – A nutritional powerhouse, kale is hardy and grows well in hydroponic setups. Plus, it can handle a little neglect, making it perfect if you’re still learning the ropes.
Pro Tip: Leafy greens don’t need intense light, so they’re great for smaller systems or lower-light environments.
2. Herbs
Herbs are some of the easiest plants to grow hydroponically. They don’t take up much space, they grow quickly, and they’re super handy to have around for cooking!
- Basil – Basil grows like wildfire in hydroponic systems, and once it gets going, you’ll have more than enough for homemade pesto and garnishing all your favorite dishes.
- Mint – Mint is nearly impossible to kill, making it an ideal beginner plant. Just be aware it spreads fast, so keep it trimmed to prevent it from taking over your garden.
- Cilantro – Love it or hate it, cilantro grows well in hydroponics and is a great addition to your salsa garden.
- Parsley – Parsley grows steadily in hydroponic systems and is perfect for those who want a reliable herb to use in everything from sauces to salads.
- Thyme – This flavorful herb is another easy grower. It’s low maintenance and adds a nice touch to your herb garden.
- Celery – Great for soups. Easy to grow.
Pro Tip: Herbs typically don’t require as many nutrients as larger plants, so you can start with a more diluted nutrient solution to avoid overfeeding.

3. Strawberries
Who doesn’t love fresh strawberries? Hydroponic systems make it possible to grow these sweet treats year-round, even if you don’t have much outdoor space.
How to grow: Strawberries require a bit more care when it comes to lighting and nutrient balance, but they’re very rewarding once you get the hang of it. Like tomatoes, they need plenty of light and a well-aerated system to prevent root issues.
Pro Tip: Strawberries can be grown in vertical hydroponic systems, which saves space and allows you to grow more plants in a small area.

4. Peppers
Peppers are another great option for beginners who want to move beyond herbs and leafy greens. Whether you like them sweet or spicy, hydroponics is a fantastic way to grow peppers in any climate.
How to grow: Start with smaller varieties like bell peppers or jalapeños, as these are easier to manage in a hydroponic setup. Peppers need a lot of light (at least 10–12 hours a day) and prefer warm temperatures, so make sure you have a good lighting system in place.
Pro Tip: Peppers love calcium, so make sure your nutrient solution contains a good amount to keep your plants thriving.
5. Tomatoes
Tomatoes are a bit more challenging than leafy greens or herbs, but they’re totally doable for beginners with a little patience. The payoff? Fresh, juicy tomatoes right from your home garden.
How to grow: Start with a smaller, determinate variety like cherry or Roma tomatoes, which are easier to manage. Make sure your plants get plenty of light (12–16 hours a day) and support them as they grow, as tomatoes tend to get top-heavy.
Pro Tip: Tomatoes are heavy feeders, so you’ll need to monitor nutrient levels closely and adjust as needed. They also thrive with consistent air circulation, so make sure your hydroponic setup has proper ventilation.

6. Cucumbers
Cucumbers are vining plants that love water, which makes them an ideal match for hydroponic systems. They grow quickly, are fairly low-maintenance, and produce a lot of fruit, making them a rewarding choice for beginners.
How to grow: Pick a bush variety if you’re limited on space. Cucumbers need support, so you’ll want to set up a trellis or some kind of structure for the vines to grow on.
Pro Tip: Make sure your cucumbers get enough light (around 12–14 hours a day) and are in a system with good ventilation to avoid mold and mildew.
7. Squash
Squash may not be the first plant that comes to mind for hydroponics, but it’s actually a great option for beginners, especially if you’re looking to grow something a little larger and more substantial. Varieties like zucchini and yellow squash thrive in a hydroponic environment and can produce a bountiful harvest.
How to grow: Squash is a vining plant, so you’ll need a sturdy trellis or support system as it grows. It prefers plenty of light (at least 12–14 hours a day) and a consistent nutrient supply. Squash plants grow quickly and can be quite large, so make sure you have enough space in your system.
Pro Tip: Squash plants can sometimes get powdery mildew, especially in humid environments. Make sure you have good air circulation and avoid getting the leaves wet to prevent this issue.
Choosing the right plants is just the start, avoiding these Common Hydroponic Mistakes will help ensure they thrive in your system.
