Mint cultivation in polyhouse and hydroponics
Grow fresh, clean mint (pudina) all year under a polyhouse, in NFT channels or cocopeat troughs. Cut every few weeks for a year or more, with a farm designed, built and supported by Kryzen.
Cut every 25–30 days
One planting lasts 12–18 months
Recirculating NFT
Why protected cultivation
Can mint be grown in a polyhouse?
Quick answer
Yes. Mint grows very well in hydroponics. Rooted cuttings are planted in NFT channels or cocopeat troughs under a polyhouse. The first cut comes about 45–60 days after planting, then the crop is cut every 25–30 days for a year or more.
A polyhouse keeps mint out of rain and harsh sun, so leaves stay clean and tender all year. Insect net keeps out aphids and whitefly, and soil-free growing stops root rot and rust from building up.
| 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 | Few cuts; slows in heat and rain | More cuts a year | A cut every 25–30 days, all 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 mint
Mint is a spreading herb that regrows after every cut. NFT channels and cocopeat troughs both work well.
Most usedNFT flatbed
Long flat channels on stands; easy to cut and clean.
Trough
Cocopeat troughs that let mint spread and fill in.
Cocopeat grow bags
Cocopeat bags with drip for small plantings.
Inside the right polyhouse
What to plant
Types of mint grown in polyhouses
Mint is sold as fresh bunches to markets, hotels, restaurants and quick commerce.
Mint (pudina)
Fresh green bunches for chutneys, drinks and cooking, sold to markets, hotels and quick commerce.
Climate and feeding
Ideal growing conditions for mint
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.
Mint / Pudina 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 mint |
|---|---|
| Season | All season in a polyhouse; cooling needed in peak summer |
| Growing temperature | 15–30 °C |
| Relative humidity | 60–75% |
| Feed TDS | About 950 ppm |
| Feed pH | 5.5–7 |
| Plant density | About 15–20 plants per m² |
| Planting material | Rooted cuttings or runners |
| Growing system | NFT channels or cocopeat troughs |
Crop cycle
From seedling to last harvest
Mint is planted once and cut again and again; a planting is usually kept for 12–18 months.
- 01

Rooting cuttings
Healthy stem cuttings are rooted in cocopeat plugs in a shaded nursery.
- 02
Day 0
Planting
Rooted cuttings are placed in the channels or troughs.
- 03
Weeks 1–6
Spreading
Plants branch and spread; tips are pinched to make them bushy.
- 04

First cut
The first cut is taken once the plants have filled in.
- 05
Every 25–30 days
Regular cuts

- 06

Replanting
Old plants are replaced when yields drop, and the system is cleaned.
Plant protection
Common mint 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 and whitefly | Sticky, curled leaves | Insect net, yellow sticky traps, early control |
| Mites | Speckled, dry leaves in hot spells | Check leaf undersides weekly, keep humidity up |
| Mint rust | Orange spots under leaves | Remove infected stems, good airflow |
| Powdery mildew | White powder on leaves | Avoid humidity swings, good spacing |
| Fusarium wilt and root rot | Plants wilt; roots turn brown | Keep nutrient water cool, clean the system between plantings |
Harvest and selling

Careful picking and grading decide the price you get.
- Cut above the baseCut stems 5–7 cm above the base so new shoots grow back fast.
- Bunch by weightTie into even bunches and keep them shaded and moist.
- Ship quicklyMint wilts fast; dispatch within hours or keep it cool.
- Sell with live pricesTrack rates on Price Watcher and reach buyers through Buyers Connect.

Can mint be grown in hydroponics?
Yes. Mint grows very well in NFT channels or cocopeat troughs and is cut every 25–30 days.
How long does one mint planting last?
Usually 12–18 months, with a cut every 25–30 days, before the plants are replaced.
Is mint grown from seed?
No. Mint is grown from rooted cuttings or runners, which root in 10–15 days.
How much revenue can mint 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.
