Things you need to grow Broccoli Microgreens

  1. 20g Broccoli seeds
  2. 10 x 20 Microgreens tray x 2 - without holes
  3. 10 x 20 Microgreens tray x 1 - with holes
  4. 6 cups of coco coir
  5. Grow lights (or sunlight)

Steps to grow Broccoli Microgreens

  1. Stack a 10x20 tray with holes on top of the 10x20 tray that does not have holes.
  2. Fill the tray (with holes) with coco coir just below the rim of the tray.
  3. Spread the Broccoli seeds as evenly as possible.
  4. Mist water once and you don't need to water again until germination.
  5. Stack another 10x20 tray on top for the first 3 Days for a Weighted Blackout. Press gently to settle the tray and push the seeds to the soil. No need to add any extra weight on the tray.
  6. On Day 4, all seeds will be germinated. Keep the 10x20 tray flipped on top like a Blackout Dome to just provide 1-2 more days of blackout so it can stretch for light a little bit more.
  7. On day 6, introduce the Broccoli microgreens to light. You can water from the bottom on Day 6 if required. Up until now, we have not given it any water but you could bottom water if you feel the weight of the tray is light.
  8. Harvest on day 9, when seedlings reach 3-4 inches.
