    The classic green, turbocharged — spinach microgreens deliver everything you love about full-grown spinach in two weeks flat.

    Medium difficulty — rewards growers who give it cool temperatures, firm soil contact, and a little patience during the slower germination phase.
    Ready to harvest in 16–20 days under ideal cool conditions (16–20 °C); best grown with a 5–7 day blackout period for strong, upright stems.
    Rich in vitamins A (β-carotene), C, E and K, plus iron, magnesium and eye-protective lutein/zeaxanthin carotenoids — studies suggest 2.5–3× higher nutrient density than mature spinach.
    Mild, sweet-green flavour with juicy, tender leaves — perfect as a salad base, blended into smoothies, layered in wraps, or scattered over warm pasta and eggs.

    General Specification

    Common Name Spinach microgreens
    Botanical Name Spinacia oleracea
    Seed Type Conventional, untreated, non-GMO
    Stem/Leaf Color Dark-green cotyledons and first leaves; pale green stems
    Flavor & Texture Mild, sweet-green spinach taste; tender leaves, juicy stems
    Seed Count per 10g ≈700–900 seeds (≈70–90 per gram; varies by cultivar)

    Cultivation Data

    Difficulty Medium (cool-loving; slower to germinate than most brassicas)
    Preferred Medium Fine, well-drained potting soil or coco coir; firm seed-to-soil contact essential
    Seeding Density (1020 tray) 60 g per 1020 tray (25×50 cm)
    Seeding Density (10x10 cm) 4.8 g per 10×10 cm
    Expected Yield ≈200–250 g per 1020 tray (approximately 3×–4× seed weight)
    Soaking Optional: pre-soak 8–12 h in cool water; pre-chill seeds in fridge 12–24 h improves germination rate
    Blackout Days 5–7 days (cool and dark for strong, upright start)
    Watering, pH & Temp Keep medium evenly moist; bottom-water preferred. pH 6.2–6.5. Ideal temperature 16–20 °C; ensure good airflow to prevent mould
    Sprouting Time 7–10 days (under cool conditions)
    Harvest Time 16–20 days (microgreen/cotyledon stage)

    Health & Nutrition

    Vitamins A (β-carotene), C, E, K, folate (B9)
    Minerals Iron, magnesium, potassium, calcium, manganese
    Notable Compounds Lutein, zeaxanthin, dietary nitrates, polyphenols (including quercetin rhamnoside, biflorin), chlorophyll derivatives, alpha-lipoic acid
    Health Benefits Supports immune function and eye health (lutein/zeaxanthin protect against macular degeneration); vitamin K supports normal blood clotting and bone health; dietary nitrates support healthy blood pressure; antioxidant polyphenols may inhibit formation of advanced glycation end products (AGEs); studies indicate 2.5–3× higher nutrient density compared to mature spinach
    ABOUT

    Spinach microgreens are the closest thing in the microgreen world to pure, unadulterated green flavour — sweet, gentle, and unmistakably spinach from the very first bite, with none of the bitterness that sometimes creeps into mature leaves. Their deep-green cotyledons and pale, juicy stems have an almost silky texture that makes them one of the most versatile garnishes in a kitchen, equally at home in a green smoothie, tucked into a croque-monsieur, or piled onto a warm bowl of lentil soup. Unlike fast-and-furious brassica crops, spinach takes its time — a slower germination and longer growing window reward the grower with noticeably fuller, more substantial leaves that hold up beautifully on a plate. Grow them now and enjoy a harvest that proves the best things really are worth waiting for.

    GROWING INSTRUCTIONS
    1 Prepare your tray: fill a shallow tray with 3–4 cm of fine, well-drained potting soil or coco coir and press the surface gently but firmly — good seed-to-soil contact is the single most important thing you can do for spinach germination, so don't skip this step. The surface should feel compact but not hard.
    2 Optional pre-soak and pre-chill: soak seeds in cool (not cold) water for 8–12 hours to soften the seed coat and speed things up, then drain well. For even better germination rates, place the drained seeds in a damp cloth in the fridge for 12–24 hours — this cool-stratification trick mimics early spring conditions that spinach absolutely loves.
    3 Sow evenly: scatter approximately 60 g of seed across a 25×50 cm tray (or 4.8 g for a 10×10 cm tray), pressing them gently into the soil surface. Cover with a thin layer of coco or fine soil — just enough to keep moisture locked in around each seed. Give the surface a light mist.
    4 Blackout phase (days 1–7): cover the tray with an inverted tray or blackout dome and keep it somewhere cool — 16–18 °C is ideal. Check daily and bottom-water if the medium starts to dry out. By days 4–5 you'll notice the first pale shoots arching upward; by day 7, they'll be pushing hard against the cover — a satisfying sign that germination is complete.
    5 Move to light (day 7 onwards): remove the cover and place the tray under grow lights or on a bright, cool windowsill. Keep the temperature between 16–20 °C and water from below by pouring into the bottom tray — this keeps the leaves dry and dramatically Maintain a pH of 6.2–6.5 and water once or twice daily as needed. You'll watch the cotyledons deepen from pale yellow to a rich, dark green over the next few days — a genuinely satisfying transformation.
    6 Encourage airflow: spinach microgreens appreciate a gentle breeze — a small fan on low nearby helps strengthen stems, evaporate surface moisture, and keep things healthy. If you notice any condensation or slow evaporation, increase airflow before problems develop.
    7 Harvest at days 16–20: when the cotyledons are fully open, dark green, and the first true leaves are just beginning to peek through, it's time. Snip just above the soil line with clean scissors on a dry morning for the best shelf life. Enjoy immediately for peak flavour and nutrition, or store unwashed in an airtight container lined with a paper towel in the fridge for up to 5 days.
