Why protected cultivation
Can basil be grown in a polyhouse?
Quick answer
Yes. Basil is one of the easiest and most profitable hydroponic herbs. Seedlings are planted in NFT channels under a polyhouse. The first cut comes about 30–35 days after planting, then the plants are cut every 2–3 weeks for 3–4 months.
A polyhouse keeps basil out of rain and harsh sun, so leaves stay tender and clean. Insect net keeps out aphids and whitefly, and NFT channels give roots steady water and food with no soil disease.
| 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 | One crop a season | Longer season | Cuts every 2–3 weeks, 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 | ₹2–3 lakh | ₹4–6 lakh | ₹7–10 lakh |
| Setup cost | Low | Medium | Highest; see your quotation and subsidy |

Where it grows
Best growing systems for basil
Basil is a fast, leafy herb. It grows best in NFT channels; grow bags suit long-running plants cut for many months.
Most usedNFT flatbed
Long flat channels on stands; the easiest system for leafy herbs like basil.
NFT A-frame
Channels stacked on an A-shaped frame to fit more plants on the same floor.
Cocopeat grow bags
Cocopeat bags with drip for basil kept and cut for many months.
Inside the right polyhouse
What to plant
Types of basil grown in polyhouses
Sweet Italian (Genovese) basil sells most to restaurants and retail; Thai basil sells to Asian kitchens and hotels.
Sweet Italian basil
Large, glossy leaves for pesto, pizza and salads; the main restaurant and retail basil.
Thai basil
Purple stems and an anise flavour for Thai and Asian cooking.
Climate and feeding
Ideal growing conditions for basil
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 basil |
|---|---|
| Season | All season in a polyhouse; cooling needed in peak summer |
| Growing temperature | 10–32 °C; best growth at 20–28 °C |
| Relative humidity | 50–70% |
| Feed TDS | About 950 ppm |
| Feed pH | 5.5–7 |
| Plant density | 20–25 plants per m² in NFT |
| Light | Bright light; 35% shade net in summer |
| Growing system | NFT channels |
Crop cycle
From seedling to last harvest
One basil crop in NFT lasts about 4–5 months from nursery to the last cut.
- 01
15–20 days
Nursery
Seeds are sown in cocopeat plugs or sponges and raised until they have 2–3 pairs of true leaves.
- 02
Day 0
Transplanting
Seedlings are placed in the NFT channels and the flow is set for young plants.
- 03
Week 2–3
Pinching
The growing tip is pinched so each plant branches out and gives more leaves.
- 04
30–35 days
First cut
The first harvest is cut once plants are bushy, about 30–35 days after transplanting.
- 05
Every 2–3 weeks
Regular cuts
Stems are cut above a leaf pair and flower buds are removed every week.
- 06
3–4 months
Crop end
Plants are replaced when they turn woody, and the channels are cleaned for the next cycle.
Plant protection
Common basil 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 leaves with grey-purple growth underneath | Good airflow, no wet leaves at night, open vents in the morning |
| Aphids and whitefly | Sticky, curled leaves | Insect net, yellow sticky traps, early control |
| Thrips | Silver streaks on leaves | Blue sticky traps, double-door entry |
| Powdery mildew | White powder on leaves | Avoid humidity swings, good spacing |
| Fusarium wilt | Plants wilt and stems turn brown | Clean seed and channels, remove infected plants |
| Root rot (Pythium) | Brown, slimy roots | Keep nutrient water below 26 °C, clean the tank between crops |
Harvest and selling
Pick, grade and sell
Careful picking and grading decide the price you get.
- Cut above a leaf pairCut each stem just above a pair of leaves so two new shoots grow from that point.
- Pinch off flowersRemove flower buds as soon as they appear; flowering makes leaves smaller and bitter.
- Pack cool and dryPack in clamshells or bunches in the cool morning and keep basil above 10 °C; it blackens in cold storage.
- Sell with live pricesTrack rates on Price Watcher and reach buyers through Buyers Connect.

Can basil be grown in hydroponics?
Yes. Basil grows very well in NFT channels under a polyhouse. The first cut comes about 30–35 days after planting, then plants are cut every 2–3 weeks.
Which hydroponic system is best for basil?
NFT flatbed is the easiest. NFT A-frame fits more plants on the same floor, and grow bags suit basil kept for many months.
How often can basil be harvested?
Every 2–3 weeks after the first cut, for 3–4 months, as long as flower buds are removed.
Why does my basil turn black?
Cold. Basil leaves blacken below about 10 °C, so do not store it in a normal cold room.
How much revenue can basil make per acre?
Expected revenue per acre for one crop cycle is about ₹2–3 lakh in open field, ₹4–6 lakh in a polyhouse with soil-based growing and ₹7–10 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 basil?
To restaurants, hotels, retail chains and quick commerce. Use Price Watcher to track rates and Buyers Connect to reach buyers.
