High-quality seeds are one of the most important factors for a successful microgreens business. Without high-quality seeds, it is impossible to grow high-quality microgreens. 

Sourcing the Best Microgreens Seeds

There are six primary factors (and many secondary factors!) to consider in procuring the best microgreens seed:

  1. Germination Rate
  2. Organic
    • While organic growing methods are crucial for the sustainability of all agriculture they are particularly important for microgreens where the seed is often the part of the plant being consumed. Be sure to source your microgreens seeds from only certified organic sources. Remember, if it’s not certified then it’s not organic.
  3. Grown Using Good Agricultural Practices (GAP)
    • Good microgreens seed starts with the planting of the crop that will produce that seed in a process that requires careful handling from seed to seed. The seed is the most likely source of human pathogen in a sprouting or microgreens system and seed growers that utilize Good Agricultural Practices for microgreens and sprouting seed ensure the seed is at minimal risk of being contaminated with a pathogen during the seed production process. This is your first line of defense against introducing a pathogen into your growing system.
  4. Pathogen Tested
    • The conditions for growing healthy microgreens are remarkably similar to those that grow good pathogens: warm, moist, and with lots of food! Finding a microgreens supplier that pathogen tests their seed is your second line of defense against introducing pathogens into your growing system.
  5. Vigour
    • A vigorous growing crop ensures you can take your microgreens from seed to sale as quickly as possible. Vigour is a sign of good seed quality and of well-stored seed in cases where the seed is older.
  6. Uniformity
    • Uniform-sized seeds usually give you uniform-sized and uniform-growing crops. A uniform corp at harvest time makes harvest quicker and easier, and with crops like sunflower, reduces time picking hulls which shed as the crop matures.
