Importance of Microgreens in Aquaponics
Aquaponics is a sustainable method of growing plants and fish together in a closed-loop system. It is a highly efficient way of producing food and is gaining popularity among urban gardeners and indoor gardening enthusiasts. However, growing microgreens in aquaponics systems has proven to be a game-changer in terms of sustainability and nutritional value.
Microgreens are young, tender plants that are harvested just after they sprout, usually within two weeks. They are packed with nutrients and have a higher vitamin and mineral content compared to mature plants. Moreover, microgreens are easy to grow and require minimal space, making them an ideal crop for indoor gardening. In aquaponics systems, microgreens can grow up to five times faster than traditional soil-based methods.
Nutritional Benefits of Microgreens
Microgreens are not only tasty but also incredibly healthy. Studies show that microgreens have a high concentration of vitamins and minerals, including vitamins C, E, and K, beta-carotene, and lutein. They also contain antioxidants that help reduce inflammation in the body.
Furthermore, microgreens are known to have a higher nutritional value than mature plants. For instance, red cabbage microgreens have 40 times more vitamin E and six times more vitamin C than mature red cabbage. Radish microgreens contain more vitamin C than mature radishes. Therefore, eating microgreens can help maintain a healthy diet while supporting sustainable food production.
How to Grow Microgreens in Aquaponics
Growing microgreens in aquaponics is relatively easy and requires minimal effort. Here are the steps you need to follow to grow microgreens in an aquaponics system:
Step 1: Choose the Right Microgreens
There are numerous types of microgreens available, such as basil, arugula, mustard, and sunflower. When choosing microgreens, consider the taste, nutritional value, and growth rate. Some microgreens grow faster than others, such as basil and arugula, while others take longer, such as sunflowers.
Step 2: Prepare the Aquaponics System
Before planting the microgreens, ensure that the aquaponics system is ready for planting. Check the pH level of the water, which should be between 6.5 and 7.5, and adjust it if necessary. Ensure that the water temperature is within the range of 68 to 86 degrees Fahrenheit.
Step 3: Plant the Microgreens
Fill a tray with a growing medium such as coconut coir, rock wool, or vermiculite. Sprinkle the microgreen seeds evenly over the growing medium and cover them with a thin layer of the medium. Ensure that the seeds are moist but not waterlogged.
Step 4: Provide Sufficient Light
Microgreens require adequate light to grow. Place the tray under a grow light or near a sunny window. Ensure that the microgreens receive at least 12 hours of light per day.
Step 5: Harvest the Microgreens
Once the microgreens have sprouted and developed their first true leaves, it’s time to harvest them. Use a pair of scissors to cut the microgreens just above the soil line. Rinse the microgreens and enjoy them fresh or store them in a refrigerator for up to a week.
