How to grow Basil microgreens


Growing Microgreens



  • Measure 3 tsp. of basil seed for the personal size 6x6 grow tray

  • Measure 8 tbsp. of basil seed for a 10x20 grow tray

  • Wet and place your grow medium in your growing tray

  • Sprinkle basil seed evenly over your grow medium

  • 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

  • Keep the grow medium moist but not saturated during the germination stage

  • Germination 4 – 5 days, keep plants covered in a dark area for this time frame

  • Do not water seeds during the germination stage

  • Basil is persnickety, while growing maintain a temperature of 65-75 degrees F to avoid disease


Growing, Harvesting and Greening Your Basil Microgreens


Lighting and Watering

Consider supplemental lighting if your environment lighting is insufficient.  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.


****Grow Tip: If you have scales, weigh your grow tray after watering.  The tray will be much heavier after watering, weigh your grow tray before your next watering, if the tray is considerably lighter you know that it is time to water again.


Days to Maturity

With basil 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, basil microgreens are harvested at ½ - 2” in height. To grow your basil microgreens to the first cotyledon stage will take approximately 10 – 15 days from the moment you plant to harvest time. In some cases, basil microgreens can take up to 16 – 25 days depending on the growing environment they are in.



When you are ready to harvest your basil 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.  



Shelf life ranges from 5 - 10 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.




Basil 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.
