Why protected cultivation
Can coriander be grown in a polyhouse?
Quick answer
Yes. Coriander grows well in NFT channels under a polyhouse. A few seeds are sown in each plug, and the plants are ready to pull or cut about 30–40 days after sowing. In hot months, cooling stops the plants from bolting.
A polyhouse keeps coriander out of rain and hot sun, so leaves stay green and clean. Cooling and shade stop early bolting in summer, and NFT channels give the plants steady water and food with no soil.
| Point |  |  |  |
|---|---|---|---|
| Season | One season; heat and heavy rain stop growth | Longer season with shade net and vents | All year, with cooling in hot months |
| Harvests | Winter only; bolts in heat | Longer season with shade | Many 35–45 day crops a year |
| Leaf quality | Mud, insect holes, uneven leaves | Cleaner, more even leaves | Clean, tender, even leaves with no soil |
| Pests | Aphids, caterpillars and leaf miners attack freely | Insect net and traps keep pressure low | Insect net and traps keep pressure low |
| Soil diseases | Root rot and wilt build up in soil | Still a risk; soil disease builds up over cycles | None; soil-free channels |
| Water and fertiliser | Flood irrigation; much is lost | Drip into soil; some is lost | Nutrient water is recirculated; very little is lost |
| Revenue per acre per cycle | ₹1–3 lakh | ₹3–5 lakh | ₹5–8 lakh |
| Setup cost | Low | Medium | Highest; see your quotation and subsidy |

Where it grows
Best growing systems for coriander
Coriander is a fast leafy herb. It grows best in NFT channels, where clean roots also let you sell plants with roots for a longer shelf life.
Most usedNFT flatbed
Long flat channels on stands; the easiest system for coriander bunches.
NFT A-frame
Channels stacked on an A-shaped frame to fit more plants on the same floor.
Trough
Cocopeat troughs for dense sowing where NFT is not set up.
Inside the right polyhouse
What to plant
Types of coriander grown in polyhouses
Coriander is sold as fresh bunches, with or without roots, to markets, hotels and quick commerce.
Coriander leaves (dhania)
Fresh green bunches for everyday cooking, sold to markets, hotels and quick commerce.
Climate and feeding
Ideal growing conditions for coriander
A polyhouse lets you hold these ranges for most of the year. Vents, shade nets, foggers or fan and pad cooling keep heat in check, and drip fertigation sets the feed. Values are from the Kryzen Plant Wiki.
Coriander Leaves in the Kryzen Plant Wiki on alpha.kryzen.com, prepared by an experienced agronomist with more than 35 years of work and hands-on experience across 100+ crop cycles. See the Agronomy Wiki.
| Factor | Ideal range for coriander |
|---|---|
| Season | All season in a polyhouse; cooling needed in peak summer |
| Growing temperature | 7–27 °C; bolts above about 30 °C |
| Relative humidity | 50–70% |
| Feed TDS | About 950 ppm |
| Feed pH | 5.5–7 |
| Plant density | 8–10 seeds per plug, plugs about 15 cm apart |
| Light | Bright light; 35–50% shade net in summer |
| Growing system | NFT channels |
Crop cycle
From seedling to last harvest
One coriander crop takes about 35–45 days from sowing to harvest, so a polyhouse can run many crops a year.
- 01
Day 0
Sowing
Split seeds are soaked and sown 8–10 to a plug in cocopeat or sponge.
- 02
Days 7–12
Germination
Seeds sprout in a shaded nursery; keep the plugs moist but not wet.
- 03
Day 12–15
Into channels
Plugs are moved into the NFT channels once the seedlings stand up.
- 04
Days 15–35
Leaf growth
Plants grow fast with steady flow, mild temperature and good light.
- 05
Day 30–40
Harvest
Bunches are pulled or cut when plants are 15–20 cm tall.
- 06
After harvest
Clean-up
Channels are cleaned and the next batch goes in straight away.
Plant protection
Common coriander pests and diseases
A polyhouse with insect net, double doors and sticky traps keeps most problems out. Catch the rest early. See the Agronomy Wiki for full guides.
| Pest or disease | What you see | How to prevent it |
|---|---|---|
| Aphids | Sticky, curled leaves | Insect net, yellow sticky traps, early control |
| Powdery mildew | White powder on leaves | Good airflow, avoid humidity swings |
| Downy mildew | Yellow patches on top of leaves | Open vents in the morning, no wet leaves at night |
| Damping off | Seedlings collapse at the base | Clean plugs and trays, do not over-water the nursery |
| Fusarium wilt and root rot | Plants wilt; roots turn brown | Keep nutrient water cool, clean the tank between crops |
| Bolting | Early flower stalks and thin leaves | Shade net, cooling in summer, harvest on time |
Harvest and selling
Pick, grade and sell

- Harvest youngCut or pull plants when they are 15–20 cm tall, before flower stalks appear.
- Sell with rootsPlants pulled with clean roots stay fresh longer and fetch a better price.
- Bunch and keep coolTie into bunches by weight and keep them cool and shaded until dispatch.
- Sell with live pricesTrack rates on Price Watcher and reach buyers through Buyers Connect.

Can coriander be grown in hydroponics?
Yes. Coriander grows well in NFT channels under a polyhouse and is ready about 30–40 days after sowing.
Why does my coriander flower early?
Heat. Coriander bolts above about 30 °C. Shade net and cooling in summer keep it leafy.
How many crops of coriander can I grow in a year?
Each crop takes about 35–45 days, so a polyhouse can run many crops a year with staggered sowing.
Should I sell coriander with roots?
Many buyers prefer it. Hydroponic roots are clean, and plants with roots stay fresh for longer.
How much revenue can coriander make per acre?
Expected revenue per acre for one crop cycle is about ₹1–3 lakh in open field, ₹3–5 lakh in a polyhouse with soil-based growing and ₹5–8 lakh in a polyhouse with hydroponics. It depends on variety, season, market price and how well the crop is managed.
Where can I sell hydroponic coriander?
To local markets, hotels, retail chains and quick commerce. Use Price Watcher to track rates and Buyers Connect to reach buyers.
