Things you need to grow Beet Microgreens

  1. 25g Beet 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 Beet 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) halfway with coco coir. Do not fill it to the top of the tray.
  3. Spread the Beet seeds as evenly as possible.
  4. Now fill the tray to the top line of the tray with coco coir to cover the seeds. Tap lightly to even out the surface.
  5. Mist water from the top until Day 3, once a day or as required depending on your grow room conditions. Just lift the tray and feel the weight.
  6. Stack another 10x20 tray on top for the first 3 Days for a Weighted Blackout. No need to add any further weight on the tray.
  7. On Day 4, seeds will be germinated. Blackout period ends, keep them under grow lights. From now on, water from the bottom.
  8. Harvest on day 13, when you start to see some true leaves developing.

Tips on growing Beet microgreens

  • Two famous varieties of beetroot microgreens are Detroit Mix and Bulls Blood.
  • Beet is very prone to damping off and molding so make sure you do not overwater.
  • If you are planning on using soil as the growth medium and it has sticks or clumps, make sure to get rid of the big ones.
  • You could add a scoop of some fertilizer with coco coir to give the seedlings a boost, but it is not required.
  • If you do not have grow lights, you can use the natural sunlight to grow your Beet microgreens. Just make sure they get enough light by placing them in a sunny windowsill or a south facing window.
  • If you don’t have a 10x20 seed tray, you could use any container you like.

Harvesting Beetroot Microgreens

Beet microgreens germinate in 2 to 3 days, and are ready for harvest by day 13. 


A typical Bulls Blood Beet harvest is expected to be 5x times, and Detroit Mix beet harvest is about 8x times the weight of the seed. For example, if you use 25g of Bulls Blood Beet seeds, you can expect a harvest of about 125g and if you use 25g of Detroit Mix Beet seeds, you can expect a harvest of about 200g.
