Why protected cultivation
Can tomato be grown in a polyhouse?
Quick answer
Yes. Tomato is one of the most grown crops in Indian polyhouses. Seedlings from a nursery are planted in cocopeat grow bags or Dutch buckets, trained up strings to 3–4 m and fed by drip. Harvest starts 70–90 days after planting and goes on for 6–8 months.
A polyhouse keeps out rain, hail and insects that spread tomato 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 or two seasons a year | Planting timed for better prices | Planting timed for better prices |
| Harvest period | Short; plants are bushy and low | Long; plants trained up strings | Longest; strong, healthy roots keep plants fruiting |
| Fruit quality | Mixed sizes; rain and soil damage | Clean fruit, more even size | Even size and colour, clean fruit |
| Viruses and pests | Whitefly and thrips spread viruses freely | Insect net and traps keep pressure low | Insect net and traps keep pressure low |
| Soil diseases | Wilt and nematodes build up in soil | Still a risk; soil disease builds up over cycles | None; clean cocopeat or clay balls |
| 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 | ₹2–6 lakh | ₹5–10 lakh | ₹1.5–4 lakh a month |
| Setup cost | Low | Medium | Highest; see your quotation and subsidy |

Where it grows
Best growing systems for tomato
Tomato is a tall vine crop. 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 tomatoes: washed cocopeat bags fed by drip.
Dutch bucket
Clay-ball buckets that reuse the run-off. Good where water is short.
Cocopeat grow slab
Ready-to-plant slabs for large, uniform plantings.
Trough
Long cocopeat troughs on the ground for row crops.

What to plant
Types of tomato grown in polyhouses
Polyhouses use indeterminate hybrids that keep growing and fruiting. Choose the type by your market; our agronomy team suggests varieties.
Round hybrid tomato
The main polyhouse tomato: firm, round fruit of even size, sold to markets, hotels and retail.
Cherry tomato
Small, sweet fruit sold in punnets. A higher price per kg for retail and restaurants.
Beefsteak tomato
Large, meaty fruit for slicing, burgers and premium retail.
Truss (vine) cherry
Cherry tomatoes harvested on the stem, sold as a whole cluster.
Indian (desi) tomato
Local sour-flavoured tomato for everyday cooking and wholesale markets.
Climate and feeding
Ideal growing conditions for tomato
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 tomato |
|---|---|
| Season | All season in a polyhouse |
| Growing temperature | 10–30 °C |
| Relative humidity | 60–75% |
| Feed TDS | About 1,500 ppm |
| Feed pH | 5.5–7 |
| Plant density | 2.5–3.5 plants per m², by variety and training |
| Plant height | Trained up strings to 3–4 m, then lowered |
| Growing media | Low-EC washed cocopeat or expanded clay balls |
Crop cycle
From seedling to last harvest
One tomato crop in a polyhouse takes about 9–10 months from nursery to the end of harvest.
- 01
25–30 days
Nursery
Seedlings are raised in protrays of cocopeat, often on ebb and flow benches, until they have 4–5 true leaves.
- 02
Day 0
Transplanting
Healthy seedlings are planted into pre-soaked grow bags or buckets and the drip is set for young plants.
- 03
Every week
Training
Each plant is clipped to a string and kept to one stem. Side shoots are removed every week.
- 04
From week 3–4
Flowering and fruit set
Flower trusses open every week. Gently shaking the trusses or strings helps pollination.
- 05
70–90 days
First harvest
Fruit is picked as it turns colour. Lower leaves are removed and plants are lowered to keep the top within reach.
- 06
6–8 months
Harvest period
Picking goes on 2–3 times a week until the crop is ended and the polyhouse is cleaned for the next cycle.
Plant protection
Common tomato 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 |
|---|---|---|
| Whitefly | Sucks sap and spreads leaf curl virus | Insect net on vents and doors, yellow sticky traps, early control |
| Tomato leaf miner (Tuta absoluta) | Larvae tunnel in leaves and fruit | Pheromone traps, remove damaged leaves, insect net |
| Thrips | Scar fruit and spread spotted wilt virus | Blue sticky traps, keep weeds out, double-door entry |
| Spider mites | Leaves turn speckled and dry in hot spells | Keep humidity up in summer, check leaf undersides |
| Early and late blight | Brown spots on leaves and fruit | Good airflow, no wet leaves at night, remove infected leaves |
| Powdery mildew | White powder on leaves | Avoid high humidity swings, open vents in the morning |
| Wilt and nematodes | Plants wilt and roots rot in soil | Soil-free cocopeat or clay balls avoid most of it |
Harvest and selling
Pick, grade and sell
Careful picking and grading decide the price you get.
- Pick at the right stagePick as fruit turns pink for distant markets, and fully red for local sale.
- Grade by size and colourSort into grades so buyers get even fruit and you get a better price.
- Pack and coolPack in clean crates, keep in shade and send within a day of picking.
- Sell with live pricesTrack rates on Price Watcher and reach buyers through Buyers Connect.

Can tomato be grown in a polyhouse?
Yes. Tomato is one of the most grown polyhouse crops in India. Plants grow in cocopeat grow bags or Dutch buckets, are trained up strings and fed by drip, and fruit for 6–8 months.
Which hydroponic system is best for tomato?
Cocopeat grow bags are the most common. Dutch buckets suit sites where water is short, and grow slabs suit large, uniform plantings. NFT is for leafy greens, not tomato.
How long does tomato take to harvest in a polyhouse?
About 70–90 days after transplanting, depending on variety and season. Harvest then continues 2–3 times a week for 6–8 months.
Which tomato varieties are grown in polyhouses?
Indeterminate hybrids that keep growing and fruiting: round hybrid tomatoes, cherry tomatoes, beefsteak and truss cherry types. Our agronomy team suggests varieties that suit your market.
How many tomato plants fit in a polyhouse?
Usually 2.5–3.5 plants per m², depending on variety, training and row layout. Your layout is planned after a site inspection.
How is a polyhouse tomato pollinated?
There is little wind indoors, so the trusses or strings are shaken gently in the late morning to release pollen.
How much revenue can tomato make per acre?
Expected revenue per acre for one crop cycle is about ₹2–6 lakh in open field, ₹5–10 lakh in a polyhouse with soil-based growing; in a polyhouse with hydroponics it is about ₹1.5–4 lakh a month. It depends on variety, season, market price and how well the crop is managed.
Is there a subsidy for polyhouse tomato?
Tomato 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 tomatoes?
To local markets, hotels, retail chains and processors. Use Price Watcher to track rates and Buyers Connect to reach buyers.
