Tips on growing Lettuce microgreens

• One of the famous varieties of Lettuce microgreens is the Ruby Red.
• If you don’t have a 10x20 seed tray, you could use any container you like.
• 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.
• If you do not have grow lights, you can use the natural sunlight to grow your Lettuce microgreens. Just make sure they get enough light by placing them in a sunny windowsill or a south facing window.

Lettuce microgreens start germinating from the first day itself, and are ready for harvest from day 8 up to day 20. You can keep growing for 20 days. 

 

A typical Lettuce microgreens harvest is expected to be 20x times the weight of the seed. For example, if you use 10g of Lettuce seeds, you can expect a harvest of about 200g
