Do my sprouts need sunlight?
Sprouts rely on the nutrient from seeds to grow and thus soil and light matter less. They actually grow best in indirect light and sometimes direct sunlight may even harm these fragile baby plants.
However, a bit of sunlights will be needed for sprouts with green leaves to perform photosynthesis in order to produce chlorophyll for greening.
On the day of harvest, expose your sprouts to light for 15 minutes and watch the magic. Their leaves will become so green and refreshing that you might want to make sandwiches with them immediately.
