Records of the cultivation of pak choi in south China date as far back as the 5th century AD. It has since spread throughout China and to other parts of Asia, where it has been widely grown in Japan, Malaysia, Indonesia, as well as the Philippines, and can also be found in Europe and America.
It is very easy to grow pak choi microgreens. You do not need to soak or rinse and drain seeds. Prepare your soil by getting it sufficiently moist. Spread seeds evenly across the surface of the soil. After seeds are sown, cover for two to three days to allow seeds to germinate, and then uncover seeds and place under a grow light. Continue to water when need. Harvest when the look and the flavor is to your liking. So, begin sampling the greens when the first set of leaves form to determine when to cut! Harvest should be ready in 8-10 days.
This is hardly surprising given how many health benefits it provides. It has a delicate flavour which means it can be added to soups and salads without overpowering the flavour of any of the other ingredients.
