There is no hard and fast rule, but here are some examples of plants that will grow well in NFTs. The list is not exhaustive, but it will give you an idea of what you can grow. Hydroponic gardeners can use a wide range of plants to grow, as long as they are adapted to low-nutrient, nutrient-poor media. These include herbs, salad greens, lettuce, and radishes, as well as fruits, vegetables, and flowers.
Also, sunflowers, lettuce, tomatoes, peppers, cucumbers, melons, squash, herbs, bulbs. If you want to grow a lot of plants, it's the best choice. I used NFTs for many years and they worked great.
