Carrot cultivation in polyhouse and hydroponics
Grow straight, clean, sweet carrots in a polyhouse or nethouse, in deep cocopeat troughs fed by drip. Even roots with no forking or soil damage, for retail, hotels and juice buyers, with a farm designed, built and supported by Kryzen.
Harvest in 90–110 days
Straight, clean roots
Exact drip feeding
Why protected cultivation
Can carrot be grown in a polyhouse?
Quick answer
Yes. Carrot can be grown under a polyhouse or nethouse in deep cocopeat troughs or raised beds. Seed is sown straight into the media, thinned after 3–4 weeks and harvested about 90–110 days after sowing.
A polyhouse or nethouse keeps heavy rain off, so roots do not crack or rot. Loose, soil-free cocopeat lets roots grow straight with no stones or nematodes, and drip keeps moisture even so roots stay sweet and smooth.
| Point |  |  |  |
|---|---|---|---|
| Season | One cool season | Longer season with shade | More crops a year, with cooling in hot months |
| Harvests | One crop a season | Two crops a year | Two to three crops a year |
| Root quality | Forked and cracked roots in heavy soil | Straighter roots in prepared beds | Straight, even, clean roots |
| Pests | Aphids, cutworms and nematodes | Insect net and traps keep pressure low | Insect net and traps keep pressure low |
| Soil diseases | Nematodes 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 | ₹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 carrot
Carrot is a root crop. It needs loose, deep media of at least 30 cm, so it grows in troughs or bags, not in NFT channels.
Most usedTrough
Deep cocopeat troughs give roots 30 cm or more of loose media.
Cocopeat grow bags
Deep grow bags with drip for smaller plantings.
Inside the right polyhouse
What to plant
Types of carrot grown in polyhouses
Orange carrots sell most. Baby carrots pulled early sell at higher prices in packs.
Orange carrot
Sweet, crunchy orange roots for retail, hotels and juice; pulled early as baby carrots for premium packs.
Climate and feeding
Ideal growing conditions for carrot
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.
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 carrot |
|---|---|
| Season | Best in cool months; cooling needed in summer |
| Growing temperature | 15–25 °C; roots turn pale and short above about 30 °C |
| Relative humidity | 60–70% |
| Feed TDS | About 1,000–1,400 ppm |
| Feed pH | 6.0–6.8 |
| Plant density | Rows 25–30 cm apart, plants 5–8 cm apart |
| Media depth | At least 30 cm of loose media |
| Growing system | Deep cocopeat troughs or raised beds with drip |
Crop cycle
From seedling to last harvest
One carrot crop takes about 90–110 days from sowing to harvest.
- 01
Day 0
Sowing
Seed is sown straight into moist media in rows; carrots are not transplanted.
- 02
7–14 days
Germination
Keep the top layer moist until all the seed has sprouted.
- 03
3–4 weeks
Thinning
Seedlings are thinned to 5–8 cm apart so every root has room.
- 04
Weeks 5–12
Root growth
Roots fill out. Even moisture stops cracking and bitter roots.
- 05
90–110 days
Harvest
Roots are pulled when the shoulders are 2–3 cm wide.
- 06
After harvest
Clean-up
Media is loosened and refreshed before the next sowing.
Plant protection
Common carrot 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 | Curled, sticky leaves | Insect net, yellow sticky traps, early control |
| Cutworms | Seedlings cut at the base | Clean media, check seedlings at night |
| Root-knot nematodes | Forked, hairy, knotted roots | Soil-free cocopeat, clean media between crops |
| Leaf blight (Alternaria) | Brown spots and dry leaf tips | Good airflow, no wet leaves at night |
| Powdery mildew | White powder on leaves | Avoid humidity swings, good spacing |
| Cracked and forked roots | Split or branched roots | Even watering, loose media with no stones |
Harvest and selling
Pick, grade and sell
Careful picking and grading decide the price you get.
- Pull at the right sizePull roots when the shoulders are 2–3 cm wide; baby carrots can be pulled earlier.
- Wash and gradeCut the tops, wash and sort roots by length and thickness for a better price.
- Store coldCarrots keep for weeks at 0–4 °C with high humidity.
- Sell with live pricesTrack rates on Price Watcher and reach buyers through Buyers Connect.

Can carrot be grown in a polyhouse?
Yes. Carrot grows well under a polyhouse or nethouse in deep cocopeat troughs or raised beds, and is ready about 90–110 days after sowing.
Can carrot be grown in hydroponics?
Yes, in deep cocopeat troughs or bags with drip. It cannot be grown in NFT channels because the roots need deep media.
Why are my carrots forked or cracked?
Forking comes from stones, hard soil or nematodes. Cracking comes from uneven watering. Loose cocopeat and steady drip fix both.
How much revenue can carrot 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.
Where can I sell carrots?
To local markets, hotels, juice bars, retail chains and quick commerce. Use Price Watcher to track rates and Buyers Connect to reach buyers.
