  • Harvesting tools Depending on your microgreens portfolio, you might need scissors or knives/blades for harvesting. Ensure the tools are sharp to make harvesting effective and more enjoyable.

  • pH Up/ pH Down They are chemicals used to adjust the pH of the water. Usually, pH increases pH, and pH down lowers the pH. pH down consists of food-grade phosphoric acid, and pH up contains potassium hydroxide and carbonate.

How to grow Microgreens in 9 steps

Follow these steps if you want to get started in growing microgreens on your farm.

  1. Get ready: Gather all the materials (shown above) needed for growing microgreens.

  2. Sanitize: Sanitize your growing trays using warm, soapy water. Also, spray it with hydrogen peroxide and rinse it out after 10 minutes. Lastly, dry off the tray using a clean cloth.

  3. Pre-soak the seeds: most seeds require soaking before spreading them over your soil. Submerge your seeds in a jar filled with water for soaking and ensure the water is sufficient.

  4. Prepare the trays: Put soil in a tray with drain holes and ensure the soil is fine without large particles like wood or stone to allow the seeds to germinate and develop properly. Spread the soil evenly and gently, tamp it flat, and dampen it by misting it or spraying with water.

  5. Spread seeds: Spread the seeds evenly across the tray to avoid overseeding. Ensure there is enough room so all seeds get enough light, water and air.

  6. Water and cover: Cover your seeds with a light layer of soil to increase the humidity for better seed germination. Mist the soil evenly and set the tray at a desired germination temperature. Depending on the species, uncover and mist regularly. Avoid excess moisture.

  7. Uncover: Uncover the tray when the baby leaves of your plant first emerge.

  8. Expose to sunlight: ensure the microgreens get plenty of sun for better development. Check it regularly and water it when necessary until harvest time.

  9. Harvest: Most microgreen species are ready for harvest ten days after sowing. You can harvest some types as early as seven days; most plants will not last 14 or 15 days before harvesting. Use the scissors to trim the microgreens above the soil line.

Issues facing Microgreens growers

Growing microgreens is effective, but you can face issues such as;

  1. Mold Mold is the most common problem that microgreen growers deal with. Mold appears as black soot or white cobwebs and ruins microgreens. Mold can be caused by a few different things like bad drainage, high room humidity, over-seeding and poor ventilaiton.

  2. Excess moisture Excess moisture will cause molds, leading to bacteria. Also, poor drainage in your farm will increase humidity leading to molds. The soil needs to be moist and not drenched. It should be spongy and not muddy if you press your fingers into the ground.

  3. Poor air circulation Insufficient airflow leads to mold formation in microgreens. You can install fans near your microgreen growing tray for better air circulation and to reduce humidity, reducing mold formation.

  4. Over-seeding Over-seeding causes a high density of stems leading to poor air circulation. Poor airflow will lead to molds.This can also lead to poor, late or inconsistent germination. The seeds might be fighting for resources if you're having germination issues.

  5. Falling over There are a few reasons this might happen but check your water (they need a lot) and they might need more light. Watering from the top also might be causing this issue. Spray instead so the water force doesn't make them sag.

  6. Tall and Leggy Plants They may need more light. There is a balance with microgreens because you keep them in the dark for some period of time. Blackout time for mocrogreens should be 3-5 days max.

  7. Poor Environment Your environment is very important when growing microgreens. Many things can happen if you don have the right humidity, light intensity, nutrients, water and temperature. Take care that they are getting the conditions they need. Taking good notes and being attentive will go a long way here.

How to prevent mold on microgreens

Apply the following tips to prevent the growth of Mold on microgreens;

  • Clean your container to prevent bacteria or microbes from infecting your microgreens.

  • Sanitize your seed by soaking it.

  • Avoid overseeding for better air circulation.

  • Maintain the proper soil moisture for the microgreens

  • Use substrate pads instead of soil

Fungus gnats

Fungus gnats are another problem that microgreen growers face. Excess moisture is the leading cause of the issue. Fungus gnats are dangerous as they can carry fungal diseases.

You can eliminate the fungus gnats by setting a trap near the microgreens. You can pour an inch of apple vinegar into a cup, add drops of dish soap and mix it thoroughly. Then, cover it with plastic wrap and poke a small hole. Fungus gnats will fly into the trap and won't be able to get out.
