At harvest, the flavour is gentle and inviting: a clean brassica sweetness with the faintest peppery warmth, nothing aggressive, nothing sharp. Snip a handful onto miso soup, ramen or a fresh grain bowl and you add both colour and a subtle savoury lift that livelier greens would overwhelm. It grows fast, asks for almost nothing, and delivers one of the most photogenic harvests in the microgreens world — which is exactly why right now is the best time to get a tray started.\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 10×10 cm (or larger) tray with 2–3 cm of good-quality potting mix and firm it gently so the surface is level.

You'll notice the tiny brown seeds almost disappear into the soil surface; that's exactly right.\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\"\u003eEnter the blackout: Stack the tray under a second tray weighted with something heavy, or slip it under a blackout dome. Keep it in the dark for 2–3 days and check moisture once daily — the seeds will be quietly putting down roots and stretching their first pale shoots upward. By day 2 you'll likely spot the first white sprout tips peeking through.\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\"\u003eBring in the light: Once most seeds have germinated and the shoots are 2–3 cm tall, remove the cover and move the tray to a bright spot — a sunny windowsill, grow light, or greenhouse shelf all work well. You'll see the pale stems begin to blush pink and the cotyledons deepen from yellow-green to vibrant red-green within a day or two. This colour shift is the anthocyanins activating in response to light.\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\"\u003eWater from below: From now on, pour a small amount of water into a saucer or tray beneath the growing tray rather than watering from above. This keeps the foliage dry, greatly and encourages strong downward root growth. Aim for a pH of 6.0–6.5 and a room temperature of 18–22 °C — consistent warmth makes all the difference.\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\"\u003eWatch them grow: Over the next several days the greens will fill out beautifully — stems lengthening, leaves unfurling and the characteristic red blush intensifying. Enjoy the process: open the grow room and take a deep breath, there's a subtle fresh brassica scent that signals healthy, active growth. Good airflow around the tray at this stage is key to preventing damping off.\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 time: Between days 8 and 12, when the first pair of leaves is fully open and the stems stand tall, harvest with sharp scissors just above the soil line. Keep the cut greens dry before storing — a loosely covered container in the fridge will keep them fresh for 3–5 days. For the best flavour and colour, use them the same day you cut them.\u003c\/span\u003e \u003c\/div\u003e\n\u003c\/div\u003e","brand":"deliseeds","offers":[{"title":"100 g","offer_id":56657373888899,"sku":"KOMATSUNA-RED-0100g","price":5.95,"currency_code":"EUR","in_stock":true},{"title":"250 g","offer_id":56657373921667,"sku":"KOMATSUNA-RED-0250g","price":11.95,"currency_code":"EUR","in_stock":true},{"title":"500 g","offer_id":56657373954435,"sku":"KOMATSUNA-RED-0500g","price":19.95,"currency_code":"EUR","in_stock":true},{"title":"1 kg","offer_id":56657373790595,"sku":"KOMATSUNA-RED-1kg","price":29.95,"currency_code":"EUR","in_stock":true},{"title":"2 kg","offer_id":56657373823363,"sku":"KOMATSUNA-RED-2kg","price":49.95,"currency_code":"EUR","in_stock":true},{"title":"5 kg","offer_id":56657373856131,"sku":"KOMATSUNA-RED-5kg","price":89.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0910\/9336\/9219\/files\/deliseeds-komatsuna-red-microgreens-seeds.jpg?v=1774388579","url":"https:\/\/deliseeds.com\/en-fi\/products\/red-komatsuna-microgreens-seeds","provider":"Deliseeds","version":"1.0","type":"link"}
