The flavour is gentle and approachable — a clean, milky sweetness with the faintest cabbage note and a satisfying snap when you bite through the juicy stems. Lay a handful over a roasted beetroot and goat's cheese salad, fold into cold rice paper rolls, or pile onto an open-faced sandwich for instant colour and texture. Red Kohlrabi is also one of the most forgiving crops in the microgreens world: it germinates fast, stands up straight, and rarely disappoints — making it an ideal first grow or a reliable weekly staple.
    GROWING INSTRUCTIONS
    1 Prepare your tray and medium: Fill a tray with holes with about 2–3 cm of good-quality potting mix or coco coir, level it gently and water from below or mist thoroughly until evenly moist but not waterlogged — squeeze a handful; it should hold together without dripping. This is your seedbed, so take a moment to make it level and consistent.
    2 Sow the seeds: Scatter approximately 9.5 g of seeds evenly across a 25×50 cm tray (about 0.76 g per 10×10 cm section). Red Kohlrabi seeds are small, hard, and round — use a shaker bottle or cup and sow in overlapping circles to avoid bare patches. Give the tray a gentle shake to settle seeds, then press them lightly into the medium with a flat board or spare tray for good soil contact.
    3 Cover and weight for blackout: Stack an empty tray on top (with a small weight of 0.5–1 kg) to apply gentle, even pressure — this dramatically improves germination uniformity and produces strong, straight stems. Keep in a dark spot at 18–22 °C. Check once daily: you should start to see pale sprouts pushing up within 2–3 days, and by day 4 the dome of seedlings will be lifting the cover — an exciting moment!
    4 Move to light: After 3–4 days of blackout, remove the cover and place the tray under a grow light positioned about 25–30 cm above the canopy, or in a bright spot with indirect natural light. Almost immediately you will watch the stems begin to deepen in colour — pale cream transitions to that distinctive violet-purple as anthocyanins develop. Ensure good airflow around the tray to keep the micro-climate fresh.
    5 Water carefully: From this point on, water exclusively from below by pouring into the outer tray without holes — this keeps the foliage dry, dramatically reducing the risk of mould. Check daily; the medium should feel consistently moist. Maintain pH 5.8–6.2 if you are monitoring your water, and keep ambient temperature at 18–22 °C.
    6 Watch them grow: Over the next 5–8 days your tray will fill with a dense, upright canopy of green-and-violet leaves reaching 5–9 cm tall. You will notice a faint fresh-vegetable scent as the tray fills in — that is the glucosinolates doing their thing. If any stems look pale or leggy, move them closer to your light source.
    7 Harvest: When the cotyledons are fully open and the stems show their best violet colour — typically days 10–12 — harvest with clean scissors just above the soil line. Taste one stem first and enjoy that juicy, sweet crunch. Do not rinse until just before serving; pat or spin dry, then store loosely in an airtight container in the fridge for up to 5 days.
