Capsicum cultivation in polyhouse and hydroponics
Grow red, yellow and green capsicum (bell pepper) all year in a polyhouse, in cocopeat grow bags fed by drip. Bigger, glossier fruit, longer harvests and fewer losses to rain, heat and pests, with a farm designed, built and supported by Kryzen.
Harvest for 7–8 months
Protected from weather
NHB subsidy crop
Why protected cultivation
Can capsicum be grown in a polyhouse?
Quick answer
Yes. Coloured capsicum is one of the most profitable polyhouse crops in India. Seedlings are planted in cocopeat grow bags, trained to 2–4 stems on strings and fed by drip. Green fruit can be picked from about 60–70 days and coloured fruit from about 90–100 days after planting, and harvest goes on for 7–8 months.
A polyhouse keeps out rain, hail, strong sun and the insects that spread capsicum viruses, and holds temperature and humidity closer to what the crop needs. Soil-free media and drip feeding remove soil diseases and give every plant the same water and food.
| Point |  |  |  |
|---|---|---|---|
| Season | One season a year | Planting timed for better prices | Planting timed for better prices |
| Harvest period | Short; mostly green fruit | Long; plants trained up strings | Longest; strong, healthy roots keep plants fruiting |
| Fruit quality | Small, thin-walled fruit; sun scald | Bigger fruit; red and yellow possible | Large, glossy, thick-walled red and yellow fruit |
| Viruses and pests | Thrips, mites and aphids spread viruses freely | Insect net and traps keep pressure low | Insect net and traps keep pressure low |
| Soil diseases | Wilt and root rot build up in soil | Still a risk; soil disease builds up over cycles | None; clean cocopeat |
| Water and fertiliser | Flood irrigation; much is lost | Drip into soil; some is lost | Exact drip doses to every plant |
| Revenue per acre per cycle | ₹10–14 lakh | ₹12–16 lakh | ₹3–10 lakh a month |
| Setup cost | Low | Medium | Highest; see your quotation and subsidy |

Where it grows
Best growing systems for capsicum
Capsicum is a tall, staked crop trained on 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 capsicum: 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 capsicum grown in polyhouses
Polyhouses grow hybrid bell peppers that are picked green or left to turn red or yellow. Coloured fruit sells for more; our agronomy team suggests varieties for your market.
Red capsicum
Fruit left on the plant until fully red. Sweet, high-value fruit for retail, hotels and export.
Yellow capsicum
Fruit that ripens to bright yellow. Sold with red as coloured capsicum at premium prices.
Green capsicum
Picked green at full size. Earlier harvest and steady demand from wholesale markets.
Climate and feeding
Ideal growing conditions for capsicum
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 capsicum |
|---|---|
| Season | All season in a polyhouse |
| Growing temperature | 18–36 °C |
| Relative humidity | 60–70% |
| Feed TDS | About 1,500 ppm |
| Feed pH | 5.5–7 |
| Plant density | 2.5–3 plants per m², by variety and training |
| Training | 2–4 stems per plant on strings, up to 3–4 m |
| Growing media | Low-EC washed cocopeat |
Crop cycle
From seedling to last harvest
One capsicum crop in a polyhouse takes about 9–10 months from nursery to the end of harvest.
- 01
30–35 days
Nursery
Seedlings are raised in protrays of cocopeat, often on ebb and flow benches, until they have 4–6 true leaves.
- 02
Day 0
Transplanting
Healthy seedlings are planted into pre-soaked grow bags and the drip is set for young plants.
- 03
Every week
Training
Each plant is trained to 2–4 main stems, each clipped to its own string. Side shoots are removed every week.
- 04
From week 4–5
Flowering and fruit set
The first flower at the main fork is removed so the plant grows strong. Fruit then sets at each node.
- 05
60–100 days
First harvest
Green fruit is ready from about 60–70 days and coloured fruit from about 90–100 days after planting.
- 06
7–8 months
Harvest period
Picking goes on once or twice a week until the crop is ended and the polyhouse is cleaned for the next cycle.
Plant protection
Common capsicum 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 |
|---|---|---|
| Thrips | Silver streaks on leaves; spread tospovirus | Blue sticky traps, insect net, double-door entry |
| Mites (broad and spider mites) | Curled, bronzed young leaves | Check new leaves weekly, keep humidity up in hot spells |
| Aphids | Sticky leaves; spread mosaic viruses | Yellow sticky traps, remove weeds, early control |
| Whitefly | Sucks sap; sooty mould on fruit | Insect net on vents and doors, yellow sticky traps |
| Powdery and downy mildew | White patches under leaves or yellow spots on top, leaf drop | Avoid humidity swings, open vents in the morning, no wet leaves at night |
| Fusarium wilt and root rot | Plants wilt and roots turn brown and rot | Soil-free cocopeat, do not over-water, good drainage |
| Blossom-end rot and sun scald | Dark sunken patch or pale burnt patch on fruit | Steady calcium feed and watering, shade net in summer |
Harvest and selling
Pick, grade and sell
Careful picking and grading decide the price you get.
- Pick at the right stagePick coloured fruit when it is 70–90% coloured, and green fruit when it is full size and firm.
- Cut, do not pullCut each fruit with its stalk using secateurs so the plant and fruit are not damaged.
- Grade by colour and weightSort red, yellow and green fruit into grades so buyers get even fruit and you get a better price.
- Sell with live pricesTrack rates on Price Watcher and reach buyers through Buyers Connect.

Can capsicum be grown in a polyhouse?
Yes. Coloured capsicum is one of the most profitable polyhouse crops in India. Plants grow in cocopeat grow bags, are trained up strings and fed by drip, and fruit for 7–8 months.
Which hydroponic system is best for capsicum?
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 capsicum.
How long does capsicum take to harvest in a polyhouse?
Green fruit is ready about 60–70 days after transplanting and coloured fruit about 90–100 days. Harvest then continues for 7–8 months.
Red, yellow or green capsicum: which should I grow?
Red and yellow capsicum sell for more but take longer to ripen on the plant. Green capsicum is picked earlier. Many farms grow red and yellow together for retail and hotel buyers.
How many capsicum 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.
Why do capsicum flowers drop?
High heat, low humidity, uneven watering or too much shade can make flowers drop. A polyhouse with shade net, foggers or fan and pad cooling keeps conditions steady.
How much revenue can capsicum make per acre?
Expected revenue per acre for one crop cycle is about ₹10–14 lakh in open field, ₹12–16 lakh in a polyhouse with soil-based growing; in a polyhouse with hydroponics it is about ₹3–10 lakh a month. It depends on colour, variety, season, market price and how well the crop is managed.
Is there a subsidy for polyhouse capsicum?
Capsicum is among the vegetables listed for NHB support on protected cultivation. Our team prepares the project report and subsidy file for you.
Where can I sell polyhouse capsicum?
To local markets, hotels, retail chains and exporters. Use Price Watcher to track rates and Buyers Connect to reach buyers.
