GROWING SUNFLOWER MICROGREENS
Measure ½ cup of sunflower seed for the personal size 6x6 grow tray
Measure 1½ cup of sunflower seed for a 10x20 grow tray
Soak your seeds completely emerged under water for 8 to 12 hours
Drain off the soak water (use it to water your plants it has nutrients in it)
Rinse your sunflower seeds thoroughly with cool 60 to 70-degree water
Repeat soak and rinse in 8 – 12 hour intervals 3 more times or until you see little white root sprouts
Wet and place your grow medium in your growing tray
Sprinkle sunflower seed evenly over your grow medium (some overlapping of seed is ok)
Gently water the seeds using a spray bottle the first time and bottom water after germination stage
Take your grow tray lid and turn it upside down and place it on top of your seeds and add a few rocks to make the sunflowers work to grow as they would under soil
Keep the grow medium moist but not saturated during the germination stage misting 2 – 3 times daily
Germination 3 – 5 days, keep plants covered in a dark area for this time frame
Once the sunflowers begin to push the lid up and are about an inch tall uncover them and introduce them to light
Lighting and Watering
Consider supplemental lighting if your environment lighting is insufficient. Sunflower need a minimum of 8 to 16 hours a day of direct light or sunlight to thrive. It is best to bottom water by lifting up the grow medium and pouring about a ½ inch of water into the grow tray and lowering the grow medium into the water. This gives the roots the water they need to quench their thirst without injuring the tiny plants. Sunflowers drink a lot of water, but be careful not to over water – if you see puddles, you have given them too much water.
Days to Maturity
With sunflower microgreens, it is best to harvest at the cotyledon stage, which is the first set of leaves your plants grow before their first true leaves grow, or once the first true leaves begin to emerge, depending on your preference or your market. Typically, sunflower microgreens are harvested at 3 - 5” in height. To grow your sunflower microgreens to the first cotyledon stage will take approximately 10 - 12 days from the moment you plant to harvest time.
When you are ready to harvest your sunflower microgreens, cut the plants just above the grow medium. We suggest that you cut them as you are ready to eat them vs cutting them and storing them. Sunflower seeds thrive when left attached to their root base.
Shelf life ranges from 7 - 14 days under proper storage conditions. Store them in an air tight plastic bag cuddled with a paper towel. Store them in the refrigerator after they have been cut.
Sunflower microgreens are prone to damping off disorder, which is associated with poor air circulation and over saturated grow mediums. Ensure air movement with horizontal airflow fans. Sunflower also are prone to mold, to avoid mold, take hydrogen peroxide and mix about half and half with water in a spray bottle and spray your sunflower seeds well before or during the germination process
