    ABOUT

    Black radish microgreens — grown from Raphanus sativus var. niger — are the most characterful member of the radish microgreen family, carrying a noticeably bolder, earthier heat than their pink or daikon cousins. The cotyledons emerge a deep, saturated green against pale, sturdy stems, and when you bite in, you get that satisfying crisp snap followed by a clean, peppery warmth that lingers just long enough. A small handful scattered over a soft-boiled egg on rye, tucked into a smoked salmon wrap, or tumbled over a warm lentil salad transforms the dish instantly — adding both structure and flavour. Black radish is also one of the easiest microgreens to grow successfully at home: no soaking, rapid germination, and a harvest in under ten days mean you are never more than a week away from a fresh tray.

    GROWING INSTRUCTIONS
    1 Fill your tray with a good-quality potting soil or coco coir to about 2–3 cm depth, pressing it gently level — a smooth, firm surface means every seed gets even contact and germinates at the same time. Pre-moisten the medium so it feels like a wrung-out sponge before you sow.
    2 Weigh out 30g of black radish seeds per 25×50 cm tray (about 2.4g for a 10×10 cm tray) and scatter them as evenly as you can using a shaker jar or by hand in two crossing passes — radish seeds are forgiving, so a little overlap is fine. Mist the seeds lightly after sowing; that first contact with water signals them to wake up and will noticeably improve germination uniformity.
    3 Stack the tray or cover it with a blackout dome and add a light weight on top — this gentle pressure encourages the roots to push downward into the medium instead of riding up on the surface. Keep the setup in a warm spot (18–22 °C) and leave it undisturbed for 2–3 days. By day two you may catch the faint, fresh scent of sprouting radish when you peek inside.
    4 Once the sprouts are about 2–3 cm tall and vigorously lifting the cover, remove the dome and expose the tray to light. At this stage the seedlings will look pale yellow or cream — that is perfectly normal and actually exciting: within 12–24 hours of light exposure you will watch them 'green up' in real time, the cotyledons deepening to a rich, dark green.
    5 Switch to bottom watering from this point on: pour a few centimetres of water into the outer tray and let the medium soak it up, then drain. This keeps the leaves and stems dry, which is the single most effective thing you can do to prevent damping-off. Water only when the tray feels light — radish prefers evenly moist, never waterlogged, conditions. Aim for a pH of 6.0–6.5 and maintain good airflow around the tray.
    6 Harvest on days 7–10 when the cotyledons are fully open and a deep, glossy green — use sharp scissors or a knife and cut just above the soil line. Take a small bunch in one hand and cut cleanly across; the crop releases that characteristic radish aroma the moment you cut. Stop watering 12 hours before harvest so the leaves are as dry as possible for the best shelf life.
    7 Rinse gently under cool water, spin or pat dry, and use immediately for maximum crunch and heat — or store loosely covered in the fridge for up to 5–7 days. Enjoy them on anything from avocado toast and grain salads to charcuterie boards and grilled fish; their bold bite brings even simple dishes to life.
