Step 1: Gathering Necessary Supplies
To set up a DIY Microgreens Tray, it’s essential to first gather all your necessary supplies. This includes buying a suitable tray, seedling mix, a spray bottle for watering, a clear plastic lid for heat retention, a grow light if there isn’t much natural light available, and your choice of microgreen seeds. A typical sized tray for growing microgreens is a 10 x 20 inches, and for seeds, almost any vegetable or herb can be grown as a microgreen.
Step 2: Choose the Right Microgreens
Choosing the right microgreens depends on your taste preference. Favorites include broccoli, fenugreek, radish, peas, beet, and mustard, thanks to their unique flavor profiles. Hard-to-digest seeds like beans and beet may require soaking before planting. Researching potential microgreens can help you understand their respective growth rates, nutritional values, and ideal conditions for successful cultivation.
Step 3: Preparing the Tray
Preparation of the tray is absolutely crucial to the germination and overall health of your microgreens. Begin by filling your tray evenly with the seedling mix. Compact it down gently, ensuring there are no lumps or high points. The mix should sit approximately one to two centimeters below the rim of the tray. Next, thoroughly moisten the soil using a spray bottle, ensuring even coverage across the surface.
Step 4: Planting the Seeds
It’s time to sow your chosen seeds. Spread them evenly over the surface of the moistened soil. As a rule of thumb, aim to cover around 70-80% of the soil surface. You may use a seed shaker to achieve a more consistent spread. Lightly press the seeds into the soil but don’t cover them as most microgreen seeds need light to germinate.
Step 5: Create a Greenhouse Effect
Creating a greenhouse effect can help speed up the germination process. Cover your tray with a clear plastic lid to retain moisture and heat. Make sure it fits snugly and has some holes for ventilation. If your tray does not come with a cover, you can use a clear plastic bag.
Step 6: The Waiting Game
Germination times vary depending on the type of microgreen you’re growing. Be patient and ensure your greens are receiving ample indirect sunlight and regular, gentle waterings. Remember to remove the plastic cover once you start to see sprouts poking up through the soil.
Step 7: Ensure Proper Growth Conditions
After germination, proper light, water, temperature, and air circulation are crucial for robust microgreen growth. Place your tray in a sunny, well-ventilated area or use a grow light for consistent lighting. Ensure your microgreens are kept at a room temperature, ideally between 60-75°F. Mist your greens gently once or twice daily, but avoid overwatering.
Step 8: Time to Harvest
Harvesting time will depend on the microgreen type, but most are ready within 10-14 days. You’ll know when your microgreens are ready when their first set of true leaves (second leaf pair) develops, and they’ve reached a height of 2-3 inches. Use a sharp knife or scissors to gently cut the microgreens just above the soil line.
Step 9: Safety and Cleanliness
Ensure the tray, spray bottle, and harvesting tools are clean and sterile. This helps prevent diseases that can damage your plants. Avoid using chemical cleaning agents, as residue can harm your plants and likely your health upon consumption.
Step 10: Replanting and Routine Maintenance
After harvesting, don’t throw away your soil. Simply remove the root mat, fluff the soil, add a bit more if needed, moisten it, and you’re ready to plant a new batch of seeds. Routine maintenance and continuity will give you a perpetual harvest of fresh, nutritious microgreens.
In conclusion, setting up your DIY Microgreens Tray doesn’t have to be a complicated process. By following these ten steps, anyone can enjoy the benefits of nutritious and tasty microgreens right in their own home. From gathering your supplies to harvesting your greens, each step brings you closer to achieving an environmentally-friendly, cost-saving, and rewarding gardening experience.
