Day 9 lettuce and day 3 kale

10 lettuce seedlings are visible, the kale are doing so good.  What I learnt is not to sow to deep.  Previously I sowed the lettuce and spinach seeds quite deep, about 1/2 inch, but for kale I push the surface of the soil to the edge, sowed the seeds randomly, and cover the soil is back.  The kale seeds were a few mm deep.
