Common Crops Used for Hydroponics

Growing crops hydroponically allows gardeners the opportunity to have fresh, home-grown vegetables at their fingertips. Home-grown vegetables taste better, cost less and, when grown in hydroponic gardens, are available all year long. The best hydroponic crops are those that don't require a lot of growing room; avoid crops that spread or take up a lot of space. Most importantly, select crops that everyone in the family enjoys eating.


One of the most popular hydroponic vegetables is the tomato, and all varieties of tomato will thrive in hydroponic conditions. Grow big, meaty beefsteak varieties such as Trust, Geronimo, Blitz and Quest. Cluster or truss tomatoes are smaller in size and grow on one vine. The Ambiance, Tradiro and Locarno are all good varieties of cluster tomatoes that grow in a hydroponic garden. Cherry tomatoes are a good choice, too: Sweet Million, Flavorita, Sakur and Sungold are a few varieties of cherry tomato that flourish in hydroponic conditions.

The bibb lettuces Salina, Rex and Vegas are small head lettuce varieties that grow well in hydroponics. Other salad greens that flourish in a hydroponic garden are endive, chicory, arugula, cresses, chard, spinach and kale. Choose varieties of lettuces that are resistant to tip burn and bolting.

Snow peas are the type of pea where the pods are also eaten (they are sometimes known as Chinese peas). Mammoth Melting Sugar and Oregon Giant Pod are two types of edible snow peas that grow in hydroponic gardens.
