When it comes to choosing plants for your aquaponics system, not all crops perform equally. Some thrive in the nutrient-rich, soilless environment, while others may require more care or simply aren’t a good fit. Whether you’re running a media bed, deep water culture (DWC), or nutrient film technique (NFT) system, here’s a look at some of the best-performing plants for aquaponics and why they succeed.
Leafy Greens
Top picks:
- Lettuce (Romaine, Butterhead, Bibb)
- Spinach
- Kale
- Swiss Chard
- Arugula
- Mustard Greens
Why they work well:
Leafy greens are reliable performers in aquaponics systems. They grow quickly, require minimal nutrients, and are well-suited to the moisture-rich, oxygenated environment. They’re also relatively resistant to common pests and diseases, making them ideal for beginners.
Herbs
Top picks:
- Basil
- Mint
- Cilantro
- Parsley
- Dill
- Chives
Why they work well:
Herbs are fast-growing, compact, and tolerant of varying nutrient levels, which makes them a great addition to smaller or newer systems. They’re also highly rewarding—small space, big flavor.
Fruiting Vegetables
Top picks:
- Tomatoes
- Peppers (Bell, Chili)
- Cucumbers
- Beans
- Peas
- Strawberries
What to know:
Fruiting vegetables require more nutrients and a more mature system with a stable nitrogen cycle. They often need support structures, like trellises or cages, and benefit from consistent pruning and monitoring. These plants are best introduced after your system is well-established and stocked with a healthy fish population.
Root Vegetables
Sometimes successful:
- Radishes
- Beets
- Carrots (best in media beds)
Why they’re tricky:
Root crops generally prefer a firm growing medium to develop properly. In aquaponics, they can grow in media beds, but results can vary depending on the variety and conditions. These are better for experimentation once you’ve gained confidence with easier crops.
