How much light do microgreens need to grow?

What are microgreens and how do you use them?
Microgreens are rapidly emerging as an added-value ingredient in kitchens and restaurants. Chefs love to use them to enhance the flavor and appearance of their plates. Microgreen's short turnaround from seeding to harvest allows for a great opportunity to learn systems quickly.

Do microgreens need light 24 hours?
Microgreens need at least 6 hours of natural light, or at least 12 hours of artificial light (use an inexpensive timer). Longer light periods give plants more time to photosynthesize and create sugars. More light also encourages shorter, denser microgreens, which means more greens and less stem.
