Microgreen-Sorte
Pak Choi Microgreens
Pak choi microgreens are the young shoots of Brassica rapa subsp. chinensis, harvested above the growing medium. They belong to the crucifer family and have a mild, fresh flavour with a light mustard note.
Variety profile
- Botanical name: Brassica rapa subsp. chinensis
- Typical growing time: 7–12 days
- Difficulty: easy
- Flavour: mild, fresh and lightly mustard-like
Seeds and preparation
Distribute the small seeds evenly and press them down only lightly. Excessive seeding density quickly creates a humid microclimate. Use only untreated, viable seeds intended for producing edible sprouts or microgreens. A small germination test before the main sowing saves space and reveals differences between seed lots.
Sowing and germination
A clean, shallow tray with drainage and a separate catch tray make cultivation easier. Moisten the growing medium evenly without leaving standing water. Distribute the seeds as closely as possible without layering them on top of one another. During the covered germination phase, check odour, moisture and seedling development every day.
Light, water and crop management
Pak choi grows quickly and compactly. Once it has emerged, cultivate it in bright light, water from below and harvest before the stems begin to stretch. When the cotyledons are upright, provide bright, uniform light. Watering from below is preferable; drain off any excess water. Allow the surface to dry slightly between waterings.
Harvesting and use
Harvest with clean scissors just above the growing medium when the cotyledons are fully open and the shoots are dry. Remove unused seed hulls and damaged plants. The young shoots work particularly well in stir-fries, bowls, salads and sandwiches. Add them just before serving.
Putting nutrients into perspective
Crispness and flavour depend heavily on the harvest time and water supply. More generally, the variety, seed lot, light, temperature, irrigation and age at harvest all affect composition. This information is not a substitute for laboratory analysis or medical advice.
Hygiene and common problems
Dense crops in warm, humid conditions can encourage plant diseases and undesirable microorganisms. Keep hands, trays and tools clean, use drinking-quality water only and do not consume any suspect batch. Common problems include patchy germination, long pale stems, adhering seed hulls and mould. Adjust seeding density, air movement, light and moisture only gradually, documenting each change.
Conclusion
Pak choi microgreens broaden the selection with a distinctive flavour characteristic of the crop. A germination test for each seed lot, clean bottom watering and a documented harvest window allow the variety to be assessed reliably.
