Why protected cultivation
Can cucumber be grown in a polyhouse?
Quick answer
Yes. Seedless (parthenocarpic) cucumber is one of the most grown polyhouse crops in India. Seedlings are planted in cocopeat grow bags, trained up strings and fed by drip. Fruit sets without bees, the first harvest comes 35–45 days after planting and one crop lasts 3–4 months.
A polyhouse keeps out rain, hail and the insects that spread cucumber viruses, and holds temperature and humidity closer to what the crop needs. Seedless varieties set fruit without bees, and soil-free media with drip feeding remove soil diseases.

Where it grows
Best growing systems for cucumber
Cucumber is a fast-growing vine trained up strings. It grows in media-filled bags, slabs or buckets with drip, not in NFT channels.
Most usedCocopeat grow bags
The most common way to grow polyhouse cucumber: washed cocopeat bags fed by drip.
Cocopeat grow slab
Ready-to-plant slabs for large, uniform plantings.
Dutch bucket
Clay-ball buckets that reuse the run-off. Good where water is short.
Trough
Long cocopeat troughs on the ground for row crops.
Inside the right polyhouse
What to plant
Types of cucumber grown in polyhouses
Polyhouses grow seedless hybrids that set fruit without bees. Choose the type by your market; our agronomy team suggests varieties.
English (long) cucumber
Long, seedless, thin-skinned fruit for retail, often shrink-wrapped.
Regular slicing cucumber
Medium-length fruit for everyday markets and hotels.
Mini (cocktail) cucumber
Small, crunchy fruit for salads and premium retail.
Sambar cucumber
Round yellow cucumber for South Indian cooking and regional markets.
Climate and feeding
Ideal growing conditions for cucumber
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.

| Factor | Ideal range for cucumber |
|---|---|
| Season | All season in a polyhouse |
| Growing temperature | 18–24 °C; tolerates up to about 30 °C |
| Relative humidity | 50–90% |
| Feed TDS | About 1,500 ppm |

Crop cycle
From seedling to last harvest
One cucumber crop in a polyhouse takes about 3–4 months from nursery to the end of harvest, so you can grow up to three crops a year.
- 01
12–15 days
Nursery
Seedlings are raised in protrays of cocopeat until they have 2–3 true leaves.
- 02
Day 0
Transplanting
Healthy seedlings are planted into pre-soaked grow bags and the drip is set for young plants.
- 03
Twice a week
Training
Each plant is wound around its string as it grows. Side shoots and fruit on the lowest nodes are removed.
- 04
From week 3
Flowering and fruit set
Seedless varieties set fruit at almost every node without bees.
- 05
35–45 days
First harvest
The first fruit is ready about 35–45 days after transplanting.
- 06
2–3 months
Harvest period
Fruit is picked every day or two until the crop is ended and the polyhouse is cleaned for the next cycle.
Plant protection
Common cucumber 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 |
|---|---|---|
| Downy mildew | Yellow angular patches on leaves, grey growth below | Avoid wet leaves and humidity swings, open vents in the morning |
| Powdery mildew | White powder on leaves | Good airflow, resistant varieties, early control |
| Thrips | Silver streaks on leaves, scarred fruit | Blue sticky traps, insect net, double-door entry |
| Whitefly and aphids | Sticky leaves; spread viruses | Insect net, yellow sticky traps, remove weeds |
| Mites | Speckled, dry leaves in hot spells | Check leaf undersides weekly, keep humidity up |
| Root-knot nematodes | Swollen roots and weak plants in soil | Soil-free cocopeat avoids them |
| Gummy stem blight | Brown, oozing patches on stems | Clean tools, good airflow, remove infected plants |

Can cucumber be grown in a polyhouse?
Yes. Seedless cucumber is one of the most grown polyhouse crops in India. Plants grow in cocopeat grow bags, are trained up strings and fed by drip, and give up to three crops a year.
Which growing system is best for cucumber?
Cocopeat grow bags are the most common. Grow slabs suit large, uniform plantings and Dutch buckets suit sites where water is short. NFT is for leafy greens, not cucumber.
How long does cucumber take to harvest?
About 35–45 days after transplanting. Fruit is then picked every day or two for 2–3 months.
Do polyhouse cucumbers need bees?
No. Seedless (parthenocarpic) varieties set fruit without pollination, which is why they suit a closed polyhouse.
How many cucumber plants fit in a polyhouse?
Usually 2.5–3 plants per m², depending on variety, training and row layout. Your layout is planned after a site inspection.
Is there a subsidy for polyhouse cucumber?
Cucumber is among the vegetables listed for NHB support on protected cultivation. Our team prepares the project report and subsidy file for you.
How much revenue can cucumber make per acre?
Expected revenue per acre for one crop cycle is about ₹2–6 lakh in open field, ₹5–9 lakh in a polyhouse with soil-based growing; in a polyhouse with hydroponics it is about ₹4–6 lakh a month. It depends on variety, season, market price and how well the crop is managed.
Where can I sell polyhouse cucumber?
To local markets, hotels, retail chains and quick commerce. Use Price Watcher to track rates and Buyers Connect to reach buyers.
