The cotyledons emerge a vivid emerald green on near-white stems, creating a striking visual contrast that looks as intentional on a restaurant plate as it does in a home kitchen. Scatter a pinch over a warm lentil soup, tuck them into a banh mi, or use them to finish a tartare — their sharp heat and satisfying snap do in seconds what a condiment takes a spoonful to achieve. With no soaking, near-perfect germination and a harvest window under two weeks, there has never been a better moment to grow your own.\u003c\/p\u003e \u003ch5\u003eGROWING INSTRUCTIONS\u003c\/h5\u003e\n\u003cdiv style=\"margin:10px 0\"\u003e \u003cdiv style=\"display:flex;gap:14px;margin-bottom:14px;align-items:flex-start\"\u003e \u003cspan style=\"flex-shrink:0;width:28px;height:28px;min-width:28px;background:#234431;color:white;border-radius:50%;display:flex;align-items:center;justify-content:center;font-size:12px;font-weight:600;margin-top:2px;line-height:1\"\u003e1\u003c\/span\u003e \u003cspan style=\"font-size:14px;line-height:1.7;color:#374151;padding-top:4px\"\u003ePrepare your tray: Fill a 25×50 cm tray with a thin, even layer of pre-moistened potting soil or a coco-fibre growing pad — aim for about 2–3 cm depth.

Do not pre-soak — these are mucilaginous seeds, meaning they form a gel-like coating when wet, which causes them to clump and stick to each other if soaked. Scatter lightly and resist the urge to pile them on; a single layer is your goal.\u003c\/span\u003e \u003c\/div\u003e \u003cdiv style=\"display:flex;gap:14px;margin-bottom:14px;align-items:flex-start\"\u003e \u003cspan style=\"flex-shrink:0;width:28px;height:28px;min-width:28px;background:#234431;color:white;border-radius:50%;display:flex;align-items:center;justify-content:center;font-size:12px;font-weight:600;margin-top:2px;line-height:1\"\u003e3\u003c\/span\u003e \u003cspan style=\"font-size:14px;line-height:1.7;color:#374151;padding-top:4px\"\u003eMist gently and cover: Using a fine-mist spray bottle, give the seeds one light pass — just enough to settle them without pooling. Stack a second tray on top to create darkness and light pressure, which encourages the roots to push down into the medium. Within 24 hours you will notice the seeds beginning to swell and the first tiny white root-tips appearing.\u003c\/span\u003e \u003c\/div\u003e \u003cdiv style=\"display:flex;gap:14px;margin-bottom:14px;align-items:flex-start\"\u003e \u003cspan style=\"flex-shrink:0;width:28px;height:28px;min-width:28px;background:#234431;color:white;border-radius:50%;display:flex;align-items:center;justify-content:center;font-size:12px;font-weight:600;margin-top:2px;line-height:1\"\u003e4\u003c\/span\u003e \u003cspan style=\"font-size:14px;line-height:1.7;color:#374151;padding-top:4px\"\u003eBlackout phase (2–3 days): Keep the covered tray in a warm spot at 18–22 °C with good airflow around it. Bottom-water once each day by pouring a small amount of water into an outer tray — this keeps the surface from becoming too wet, which is crucial with mucilaginous seeds. By day 3 you will see a forest of pale, eager shoots pushing against the lid.\u003c\/span\u003e \u003c\/div\u003e \u003cdiv style=\"display:flex;gap:14px;margin-bottom:14px;align-items:flex-start\"\u003e \u003cspan style=\"flex-shrink:0;width:28px;height:28px;min-width:28px;background:#234431;color:white;border-radius:50%;display:flex;align-items:center;justify-content:center;font-size:12px;font-weight:600;margin-top:2px;line-height:1\"\u003e5\u003c\/span\u003e \u003cspan style=\"font-size:14px;line-height:1.7;color:#374151;padding-top:4px\"\u003eBring to the light: Remove the cover once shoots reach about 2–3 cm — they will be a creamy yellow-white at this stage, which is perfectly normal. Move the tray under a grow light or to a bright windowsill; within 12–24 hours the cotyledons will transform to a deep, lively green as chlorophyll develops. This colour change is one of the most satisfying moments in microgreens growing.\u003c\/span\u003e \u003c\/div\u003e \u003cdiv style=\"display:flex;gap:14px;margin-bottom:14px;align-items:flex-start\"\u003e \u003cspan style=\"flex-shrink:0;width:28px;height:28px;min-width:28px;background:#234431;color:white;border-radius:50%;display:flex;align-items:center;justify-content:center;font-size:12px;font-weight:600;margin-top:2px;line-height:1\"\u003e6\u003c\/span\u003e \u003cspan style=\"font-size:14px;line-height:1.7;color:#374151;padding-top:4px\"\u003eWater and grow (days 4–10): Continue bottom-watering once daily, keeping the medium evenly moist but never soggy. Maintain good air circulation — black mustard is vigorous but will dampen off if airflow is poor. Watch as the stems thicken and the leaves open wide; the aroma will grow noticeably spicier each day.\u003c\/span\u003e \u003c\/div\u003e \u003cdiv style=\"display:flex;gap:14px;margin-bottom:14px;align-items:flex-start\"\u003e \u003cspan style=\"flex-shrink:0;width:28px;height:28px;min-width:28px;background:#234431;color:white;border-radius:50%;display:flex;align-items:center;justify-content:center;font-size:12px;font-weight:600;margin-top:2px;line-height:1\"\u003e7\u003c\/span\u003e \u003cspan style=\"font-size:14px;line-height:1.7;color:#374151;padding-top:4px\"\u003eHarvest: When the cotyledons are fully open, bright green and sitting at 5–8 cm tall — typically between day 8 and day 12 — harvest with sharp scissors, cutting just above the growing medium. Rinse gently, spin dry and use immediately for maximum heat and crunch. Any excess keeps in a sealed container in the fridge for 3–4 days.\u003c\/span\u003e \u003c\/div\u003e\n\u003c\/div\u003e","brand":"deliseeds","offers":[{"title":"100 g","offer_id":56657374314883,"sku":"MUSTARD-BLACK-0100g","price":3.95,"currency_code":"EUR","in_stock":true},{"title":"250 g","offer_id":56657374347651,"sku":"MUSTARD-BLACK-0250g","price":7.95,"currency_code":"EUR","in_stock":true},{"title":"500 g","offer_id":56657374380419,"sku":"MUSTARD-BLACK-0500g","price":12.95,"currency_code":"EUR","in_stock":true},{"title":"1 kg","offer_id":56657374216579,"sku":"MUSTARD-BLACK-1kg","price":19.95,"currency_code":"EUR","in_stock":true},{"title":"2 kg","offer_id":56657374249347,"sku":"MUSTARD-BLACK-2kg","price":29.95,"currency_code":"EUR","in_stock":true},{"title":"5 kg","offer_id":56657374282115,"sku":"MUSTARD-BLACK-5kg","price":59.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0910\/9336\/9219\/files\/deliseeds-mustard-black-microgreens-seeds.jpg?v=1774388753","url":"https:\/\/deliseeds.com\/en-dk\/products\/black-mustard-microgreens-seeds","provider":"Deliseeds","version":"1.0","type":"link"}
