Microgreens Farming
Tiny greens, premium price — a clean, fast, low-space city crop for chefs & D2C.
Microgreens — tiny greens, premium price
Microgreens are young edible greens harvested 7–21 days after germination, at the seed-leaf to first-true-leaf stage. They're a clean, fast, low-space city crop that chefs and health buyers pay a premium for.
Microgreens are NOT sprouts
Sprouts grow in water, in the dark, for 2–5 days, and you eat the whole thing (root + seed). Microgreens grow in a medium, under light, for 7–21 days, and you eat only the stem + leaves cut above the medium. This matters for food safety: sprouts (warm, wet, root eaten) caused many bacterial outbreaks; microgreens are lower-risk — but still handle them as fresh ready-to-eat produce.
Reality check on the marketing
The famous "up to 40× the nutrients" claim is real only for specific pairs — the honest average is about 5×. And every rosy "one tray = ₹X" projection assumes you sell nearly 100%. With a 5–7 day shelf life, selling is the hard part, not growing. Line up a buyer before you sow.
Your low-cost setup (₹10,000–30,000)
A shelf, some trays, a cheap growing medium, LED lights and a small fan — that's a real microgreens unit.
Trays (1020, 10×20")
Use two nested: a holed tray (medium + drainage) inside a solid tray (water reservoir for bottom-watering). ~₹100/tray, reusable.
Medium
Coco-peat (cheap, ₹14–30/kg, reusable) is most popular; hemp/jute mats are mess-free but single-use; soil gives top yield but is messy.
LED grow lights
Full-spectrum 6500 K, 12–16 h/day, 15–30 cm above the canopy. Too far = leggy/pale.
Airflow + mister
A small fan (after blackout) + a fine mister + a humidity dome for germination.
The grow cycle, step by step
Every tray follows the same five steps. The blackout phase builds strong stems.
Sow evenly
Spread seed on damp medium — no piles. Small seeds (radish, mustard, broccoli) ~14–56 g/tray; large seeds (sunflower 125–150 g, pea 200–275 g) — soak the big ones 6–12 h first. Never pre-soak mucilaginous seeds (basil, coriander whole).
Blackout (2–4 days)
Cover in complete darkness with a light weight (~3 kg) on top. This forces even germination and stronger stems. Keep ~21°C and mist. Move to light when shoots are 1–2 cm.
Light phase
Under 6500 K LED, 12–16 h/day. Stems green up and stand tall.
Bottom-water
Pour water into the solid reservoir tray, not over the leaves — dry canopy = no mould. Keep the medium like a wrung-out sponge, never pooling.
Harvest (7–21 days)
Cut just above the medium with clean scissors, ideally in the evening. Don't wash before storing — refrigerate dry at 1–4°C (10–14 day shelf life vs 2–4 days at room temp).
Best varieties for India
Start with the fast, forgiving ones; add colour/premium types once confident.
| Variety | Days | Soak? | Difficulty |
|---|---|---|---|
| Radish (mooli) | 5–10 | No | Easiest — start here |
| Mustard (sarson) | 8–12 | No | Easy |
| Fenugreek (methi) | 7–12 | No | Easy — familiar flavour |
| Pea (shoots) | 8–14 | Yes 8–12 h | Easy — forgiving |
| Sunflower | 8–14 | Yes 6–12 h | Easy — biggest yield |
| Broccoli | 8–12 | No (sieve) | Easy–medium |
| Beetroot (chukandar) | 10–14 | Yes 4–8 h | Medium — prized for colour |
| Coriander (dhania) | 14–21 | Split seed | Hardest — slowest |
Beginner trio
Radish + sunflower + pea — fast, forgiving, high yield. Add mustard + methi (familiar Indian flavours) next. Save coriander & beetroot for once you're confident.
Problems & fixes
The #1 killer is mould / damping-off — worst in the monsoon. Learn to tell mould from harmless root hairs.
| Problem | Cause | Fix |
|---|---|---|
| Mould / damping-off | Overwatering, no airflow, dense sowing, high humidity | Add a gentle fan; bottom-water only; cut seed density 15–20%; sanitise trays; spot-treat with food-grade 3% H₂O₂. If >20% of a tray — compost it |
| Leggy / pale growth | Light too far, too dim or too short | Lower lights to 15–30 cm; extend to 12–16 h/day |
| Uneven germination | Uneven sowing, old seed, wrong temp | Spread evenly, weight the tray, hold ~21°C, over-seed if viability is low |
| Sunflowers falling over | Usually underwatering | More bottom-water |
Food safety & hygiene
Microgreens are eaten raw, so treat them as fresh ready-to-eat produce.
- Use only clean, potable water.
- Sanitise trays between crops (soak in diluted food-grade H₂O₂ or vinegar, then rinse).
- Wash hands and scissors before harvest; harvest into clean, dry containers.
- Do not wash microgreens before refrigerating — moisture causes rot; wash at point of use.
- Keep the grow area ventilated and dry. Never mix vinegar + hydrogen peroxide.
- Maintain the cold chain (1–4°C) to your buyer.
Economics — growing is easy, selling is hard
Retail can reach ₹100–500 per 100 g (₹1,500–5,000/kg) but B2B to hotels/restaurants realises ~₹1,200/kg. Seed costs ~₹600/kg and a good crop returns roughly 3× the seed spend.
Grounded real examples
A Chennai grower makes ~₹60,000/month from 300 sq ft (~60 kg/month); a Kerala grower supplying 20–25 channels does ₹2–3 lakh/month in sales. Both spent time building buyers first.
The honest truth
Every rosy "one tray = ₹X/month" projection assumes you sell nearly 100% — and waste is the biggest margin killer with a 5–7 day shelf life. Rule #1: line up your buyer before you sow. Visit restaurants, cafés, gyms, organic stores and chefs. Metro markets are getting saturated. Be wary of 10-minute quick-commerce for a perishable — platform fees run 35–50% and unsold stock comes back to you.
Best buyers
Fine-dining restaurants & hotels, gyms & health-food stores, hospitals, and scheduled D2C / subscription boxes (which suit fresh perishables better than instant delivery).
Do's & Don'ts of microgreens
DO
- Line up a buyer before you sow.
- Start small (10–20 trays) with easy varieties (radish, sunflower, pea).
- Spread seed evenly at the right density.
- Soak large seeds (sunflower, pea, beet) 6–12 h.
- Weight trays during blackout; run a gentle fan after.
- Bottom-water; keep the canopy dry.
- Give 12–16 h of 6500 K light at 15–30 cm.
- Sanitise trays each cycle; use clean water.
- Refrigerate dry at 1–4°C; wash at use.
- Run your own yield test per variety.
DON'T
- Don't overhead-water after sprouting (invites mould).
- Don't sow too densely or overwater.
- Don't skip airflow — stagnant humid air is mould heaven.
- Don't confuse root hairs with mould (rinse test first).
- Don't pre-soak mucilaginous seeds (basil, coriander whole).
- Don't wash before storing.
- Don't over-scale before you have steady buyers.
- Don't trust "40× nutrients / one-tray-₹X" at face value.
- Don't use dirty trays or old low-viability seed.
- Don't bank on 10-minute quick-commerce for a perishable.
