Soak Seeds (Recommended) Soak Arugula Microgreens Seeds in cool water for 8-12 hours.
Prepare a Pot and Soil Get a shallow growing tray - not more than 2 inches deep. Fill it with a seed starting potting mix. The soil level should be 1-2 inches.
Plant Seeds Moisten the potting soil with water using a spray bottle. Gently sprinkle seeds evenly over the soil so they are close. Spray the surface of the soil and seeds with water again.
Germination Process Place the tray in a spot away from direct sun exposure. Make sure the soil temperature is around 70°F. Avoid drafty spots. Moisten the soil with water using a spray bottle 3-4 times a day. Don't let the soil dry out, but also do not overwater it.
Growing Once seeds start sprouting, make sure you are exposing the microgreens to at least 10 hours of daylight (use a grow light if there is not enough sun). Keep the soil moist.
Harvest In 5-12 days microgreens will be ready to harvest. When seedlings are 1 to 2 inches tall and have about two sets of leaves, snip and prep. However, you can grow them more or less by your preferences.
One of the best arugula growing media is organic potting soil. It is necessary to prepare the soil well, evenly, and moistly before sowing the seeds. The alternative medium should contain the best nutrients for arugula microgreens.
For the seeds to yield fruitfully, the correct amount of seeds must be evenly distributed over the growing surface.
Provide the ideal temperature, moisture, and light for the arugula microgreens. After planting seeds, cover the growing tray for approximately 72 hours for optimal germination. The air temperature should be about 70 degrees F. Arugula loves sunlight; this is good for its growth, so after germination, open the tray and move it to a sunny location.
You can harvest arugula microgreens from one to two weeks; it retains the most delicate taste. For optimal nutritiоn and flavor, harvest microgreens at the peak of their growth cycle.
Arugula takes root quickly and produces hundreds of tiny root hairs. Please don't rush to mistake them for harmful mold! They are evenly distributed and clustered around the main root of your seedling.
