Our easy to follow step by step growing guide will teach you how to plant your microgreens, harvest your microgreens, and store your microgreens. Gather the supplies described above and get ready to begin growing French corn salad microgreens.
The first step involves preparing your growing trays and getting them ready for planting your microgreen seeds. Start by grabbing your tray with drainage holes and filling it with your preferred growing medium. Once your tray is filled, gently press the growing medium down, ensuring the soil is even and spread to the corners. The soil level should be slightly below the top of the tray. If necessary, add more growing medium until it is level and slightly below the top of the growing tray.
Next, you want to thoroughly wet the soil. You can do this by setting your prepared growing tray in a few inches of water for 30 minutes, allowing the soil to draw water upward. Another option is to use your misting bottle and saturate your soil. Allow the water to soak in for 15 minutes. Then, spray an additional 3 to 4 times to ensure the soil is saturated completely.
You will need approximately one ounce of French corn salad microgreens seeds for every 10 by 20 inch growing tray. There are approximately 17,000 seeds in each ounce. Because the seeds are so tiny, an herb shaker bottle like this one will help you sow your French corn salad microgreens seeds.
Shake the seeds evenly across the entire soil surface. Make sure that the seeds are spread into each corner. Then, gently sprinkle some growing medium over the seeds until they are barely covered. Finally, gently pat down the soil with your hands to press the seeds into the soil.
Once you have sewn your French corn salad microgreen seeds, they are ready to germinate. Seeds must be placed in the darkness and subjected to pressure to germinate properly. This can be accomplished by inverting the final tray atop your soil and putting a weight atop the inverted tray.
Grab a heavy book, stone, or weight and place it atop the inverted tray. This will mimic the pressure and weight the seed would experience if it were planted in the ground. You may be concerned that this weight will harm your seeds; however, it will not. In fact, the weight will ensure that the French corn salad microgreens grow healthy and strong.
Next, place your grow tray on your grower's rack and atop a heating mat. The optimal soil temperature is between 65 and 70 degrees Fahrenheit. The heating mat will keep your soil at a constant temperature throughout the germination process.
French corn salad microgreens germinate rather quickly, so you will probably not need to water your growing medium; however, checking the moisture level daily will ensure the soil doesn't dry out. If the soil becomes dry to the touch, you can gently spray the top of the soil with your mister or water from the bottom as described above.
Your French corn salad microgreens should germinate within 3 or 4 days. Once 90 percent of your seeds have sprouted, it is time to remove the weight and the inverted tray. You will then be ready to place your French corn salad microgreens under grow lights to activate photosynthesis.
When the top growing tray is removed, your microgreens will be a whitish yellow. This is nothing to worry about. Once you place your microgreens under a grow light, they will quickly turn green.
For optimal growth and development, your microgreen tops should be within 12 inches of the grow light. This will ensure optimal photosynthesis will occur. Photosynthesis is the process where the plant begins producing chlorophyll, which is what causes the plants to turn bright green.
Your full spectrum LED grow lights should remain on for 12 to 16 hours each day. This will provide your plants with the amount of light that they would receive if they were planted outdoors. For the other 8 hours, your plants should be exposed to darkness.
Circulation fans are designed to increase the airflow around your French corn salad microgreens. Because microgreens are planted so close together, they are at an increased risk of soilborne diseases. Circulation fans reduce this risk.
Attach your circulation fans on the sides of your grow rack. When attaching the fans, make sure they are positioned so the air will blow across the top of your microgreen leaves. The airflow should not blow across the soil as this will cause your soil to dry out prematurely.
It takes approximately 8 to 12 days for your French corn salad microgreens to reach the microgreen size and be ready for harvest. French corn salad microgreens will be ready to harvest when they reach approximately 2 to 3 inches high, and the first set of true leaves begin forming.
Once this occurs, taste your corn salad microgreens and ensure they have the flavor profile and texture that you want. When they have reached this level, it is time to harvest your microgreens; however, before doing so, withhold water from your French corn salad microgreens for 12 hours to increase the lifespan of your harvested microgreens.
Once your French corn salad microgreens are ready for harvest, you must work quickly. The delicate stems must not be crushed during the harvesting process as this can shorten the lifespan. Furthermore, the microgreens should not be exposed to any water and should be placed in storage quickly for best results.
You will need a few clean, dry paper towels, an airtight storage bag or container, and a pair of sharp scissors or a sharp knife. Place a few paper towels on your countertop or a clean plate. Then, gently grasp your microgreens in one hand, and using the sharp knife or pair of scissors cut the microgreens slightly above the top of the soil. As you cut your microgreens, lay them in a single layer on your paper towels.
Only harvest one tray of microgreens at a time and follow these storage instructions to maximize storage lifetimes. Once you have harvested your French corn salad microgreens gently wrap them in a clean, dry paper towel and place them in an airtight storage container or storage bag.
Place your French corn salad microgreens immediately in your refrigerator. For best results, place your microgreens in the vegetable crisper. The optimal storage temperature for French corn salad microgreens is between 35 and 40 degrees Fahrenheit. When properly harvested and stored, your French corn salad microgreens will last about two weeks in the refrigerator.
