Thriving Greens: The Joy of Growing Microgreens Hydroponically

Microgreens are one of the easiest and most rewarding crops to grow at home. They are the young sprouts of edible plants, such as lettuce, kale, basil, and radish, that are harvested when they have their first true leaves. Microgreens are delicious, nutritious, and versatile, and can be added to any dish for a burst of color and flavor. But what if you don’t have a backyard or a balcony to grow them? No problem! You can grow microgreens hydroponically, which means using water instead of soil as the growing medium. In this guide, we will show you how to grow microgreens hydroponically, step by step, with simple tools and materials.

Nutrient Solution for Microgreens: Dos and Don’ts

Dos

Don'ts

Use a nutrient solution specifically formulated for microgreens.

Avoid using tap water; it may contain harmful chemicals and minerals detrimental to microgreens.

Maintain the right balance of nutrients in the solution.

Don't overfeed your microgreens; excessive nutrients can lead to nutrient burn and plant damage.

Change the nutrient solution every 7-10 days to prevent salt buildup.

  • Change the nutrient solution every 7-10 days to prevent the buildup of harmful salts.
  • Monitor your microgreens approximately every twelve hours to ensure proper growth.
  • Ensure that your hydroponic system is clean and free of debris.

Common Challenges and Troubleshooting Tips

Here are some common challenges and troubleshooting tips for hydroponic microgreens:

  1. Yellowing of microgreens: This can happen if the microgreens are not getting enough light or nutrients. To fix this, provide more light and adjust the nutrient solution as needed.
  2. Mold growth: Mold growth can occur if the growing medium is too wet or if the humidity is too high. To fix this, reduce the amount of water you are providing and increase air circulation.
  3. Root rot: Root rot can occur if the roots are sitting in water for too long. To fix this, reduce the amount of water you are providing and increase air circulation.
  4. Nutrient burn: Nutrient burn can occur if the nutrient solution is too concentrated. To fix this, dilute the nutrient solution as needed.

FAQs

Do microgreens regrow after cutting?

Microgreens typically do not regrow after cutting. Once harvested, the plants are usually not capable of producing new growth. For a continuous harvest, it’s common to sow new seeds for successive crops.

Do you need fertilizer when growing microgreens hydroponically?

Yes, fertilizer is essential when growing microgreens hydroponically. Hydroponic systems rely on nutrient solutions to provide the necessary elements for plant growth. Using a balanced and specific nutrient solution ensures optimal development and nutritional content in microgreens.

Is it better to grow microgreens in soil or water (hydroponically)?

The choice between soil and hydroponic cultivation depends on personal preferences, space, and resources. Both methods can yield healthy microgreens. Hydroponic systems offer controlled environments, efficient nutrient delivery, and potentially faster growth, while soil cultivation provides a more traditional approach.

Are microgreens actually healthy?

Yes, microgreens are considered highly nutritious. Despite their small size, they are packed with vitamins, minerals, and antioxidants. Microgreens are known to have concentrated flavors and can be a valuable addition to a balanced diet, providing a boost of nutrients.

How many hours of light do microgreens need?

Microgreens generally require around 12 to 16 hours of light per day during the growth phase. Adequate light exposure is crucial for photosynthesis and the development of vibrant and healthy microgreens. LED grow lights are commonly used for indoor cultivation to provide the necessary light spectrum.

Can microgreens grow to full size when grown hydroponically?

Microgreens are typically harvested at an early stage, well before reaching full maturity as seen in larger plants. While hydroponic systems can support the growth of larger plants, the goal with microgreens is to harvest them at a tender and flavorful stage, making them suitable for consumption in salads, sandwiches, or garnishes.
