Plenty of tiny black insects in the worm bin. Put in a white cloth (so you can see the insects clearly) for a few days, the insects would attach to the top or bottom of the cloth, remove the cloth and soak in soap or enzyme to kill the insects.

This would help to keep the insect population under control.

It is proven this lemon mint/balm doesn't like direct sunlight, so it thrives in shades.

Plenty of flowers, healthy leaves, but no fruits.

Harvested in the corn microgreens in the worm bin after 10 days. Some tasted sweet, while others slightly bitter.

Second harvest. This is as big as it gets (due to limited sunlight), and the plants start to dry up.
