In this blog, we’ll provide a comprehensive guide on growing hydroponic microgreens from start to finish. So, stay with us by reading the entire guide.Â
Why Hydroponic Microgreens Are Gaining Popularity
Microgreens are small, nutrient-dense plants harvested when just a few inches tall. Growing microgreens hydroponically, which means without soil, has become increasingly popular due to its many benefits. Here, we’ll explore the advantages of growing hydroponic microgreens.
Higher Yield in Less Space
Growing microgreens hydroponically allows for a higher yield in a smaller space than traditional soil-based methods. Hydroponic systems can be stacked vertically, maximizing the use of space. This makes it an ideal option for people with limited plant growth space.
Faster Growth
Hydroponic microgreens have a faster growth rate than those grown in soil. This is because the nutrient solution the plants are grown in provides all the necessary nutrients needed for growth, which can be absorbed by the plant roots more efficiently.
Controlled Environment
With hydroponic systems, you have complete control over the environment in which your microgreens grow. You can control the temperature, humidity, light, and nutrient levels, ensuring optimal growing conditions. This control can result in healthier, more robust plants less susceptible to disease and pests.
Less Water Usage
Hydroponic systems use less water than traditional soil-based methods. The water in a hydroponic system is recirculated and reused, reducing water waste. This makes hydroponic microgreens an ideal option for people looking for a sustainable way to grow plants.
Variety of Microgreens
Hydroponic microgreens offer wide varieties, including popular options like sunflower, rocket, and mustard microgreens. With hydroponic systems, you can easily grow a variety of microgreens all year round, regardless of the weather or season.
Better Flavor and Nutrition
Hydroponic microgreens have a better flavor and higher nutrient content than those grown in soil. This is because the plants receive all the necessary nutrients to grow properly, resulting in healthier and more flavorful microgreens.
How To Grow Hydroponic Microgreens
Hydroponic microgreens are easy to grow and can be grown indoors, making them a great option for those with limited outdoor space. Here are some tips on how to grow hydroponic microgreens:
1. Germination and Seed Selection
Select high-quality microgreen seeds, such as rocket, sunflower, or mustard seeds, and soak them in clean water for 12–24 hours to speed up germination. Once soaked, plant them in a seed tray with coconut coir, a popular medium for hydroponic systems.
2. Water and Nutrient Solutions
Microgreens require a constant supply of water and nutrients. The ideal water pH for hydroponic microgreens is between 6.0 and 6.5. Ensure that the water level in the tray is always balanced and that the water is clean. A water pump can help circulate the water and prevent algae growth. Liquid nutrient solutions can be added to the water to provide essential nutrients.
3. Lights and Temperature
Microgreens require bright light for optimal growth, and LED grow lights are a popular choice for indoor growers. Ensure that the microgreens have access to light for at least 12–16 hours per day. The optimal temperature for hydroponic microgreens is between 60-75 °F.
4. Harvesting and Scale
Microgreens are typically harvested when they have developed their true leaves, which takes 10–14 days. They can be harvested by cutting the leaves just above the soil level. Microgreens can be grown in batches, allowing for a continuous supply. The scale of production can be increased by adding additional trays.
5. Varieties and Flavor
There are many microgreens to choose from, including common microgreens like pea shoots and sunflower microgreens and less common varieties like fenugreek and rocket microgreens. Each variety has a unique flavor profile, so experiment to find your favorites.
6. Moisture and Space
Keep the microgreens moist but not too wet, as excess water can lead to mold and fungal growth. Ensure that there is enough space between the seeds to allow for proper growth and airflow.
Different Types of Microgreens to Grow Hydroponically
Hydroponic microgreen gardening has become popular among urban gardeners and those with limited outdoor space. Here are some of the different types of microgreens that you can grow hydroponically.
Leafy Greens
Leafy greens such as spinach, lettuce, and kale are popular choices for hydroponic microgreen gardening. These plants are easy to grow and have a short germination period. They are also packed with nutrients and can be harvested within 10–14 days of planting.
Herbs
Herbs such as basil, cilantro, and parsley are excellent choices for hydroponic microgreen gardening. They add flavor and aroma to any dish and are easy to grow in a hydroponic system. Herbs can be harvested within two weeks of planting and can be used in a variety of dishes.
Radish
Radish microgreens are known for their peppery flavor and can be harvested within 7–10 days of planting. They are easy to grow and are packed with vitamins and minerals. Radish microgreens are a popular choice for salads and sandwiches.
Broccoli
Broccoli microgreens are rich in antioxidants and can be harvested within 7–10 days of planting. They have a mild, nutty flavor and are a great addition to salads and sandwiches. Broccoli microgreens are also rich in sulforaphane, a compound linked to various health benefits.
Pea
Pea microgreens are rich in protein and can be harvested within 7–10 days of planting. They have a sweet, nutty flavor and are popular for salads and sandwiches. Pea microgreens are also rich in vitamins A, C, and K.
Sunflower
Sunflower microgreens are rich in vitamins E and B6 and can be harvested within 7–10 days of planting. They have a nutty flavor and are popular for salads and sandwiches. Sunflower microgreens are also rich in antioxidants and can help boost immunity.
Troubleshooting Common Issues When Growing Hydroponic Microgreens
Like any gardening method, growing hydroponic microgreens can be challenging to overcome. Below, we’ll explore some of the most common issues when growing hydroponic microgreens and how to troubleshoot them.
1. Mold and Mildew
One of the most common issues with hydroponic microgreens is mold and mildew. This can be caused by excess moisture or poor air circulation. To prevent mold and mildew, ensure your growing containers have drainage holes and avoid overwatering your plants. Additionally, consider adding a fan to improve air circulation around your plants.
2. Nutrient Deficiencies
Microgreens require specific nutrients to grow properly, and a deficiency can lead to stunted growth or discolored leaves. To prevent nutrient deficiencies, use a high-quality hydroponic nutrient solution and follow the manufacturer’s instructions for mixing and application. You may also consider testing your water source to ensure it has the necessary minerals.
3. pH Imbalances
The pH level of your hydroponic solution is important for the health and growth of your microgreens. A pH imbalance can cause nutrient deficiencies and other issues. To check the pH level of your solution, use a digital pH meter or test strips. Adjust the pH as needed using a pH-up or pH-down solution.
4. Pests and Diseases
Like other plants, hydroponic microgreens can be vulnerable to pests and diseases. Common pests include spider mites, aphids, and whiteflies, while common diseases include damping off and root rot.Â
To prevent pests and diseases, ensure your growing area is clean and debris-free. Consider using natural pest control methods like neem oil or beneficial insects. Remove the affected plants immediately to prevent further spread if you notice any signs of disease, such as wilting or discoloration.
