Many crops a year
Exact drip feeding
Why protected cultivation
Can radish be grown in a polyhouse?
Quick answer
Yes. Radish grows well under a polyhouse or nethouse in deep cocopeat troughs or raised beds. Seed is sown straight into the media and the roots are ready about 30–45 days after sowing, so you can run many crops a year.
A polyhouse or nethouse keeps heavy rain and harsh sun off, so roots stay crisp and mild. Loose cocopeat lets roots grow straight, and insect net keeps out aphids, flea beetles and sawflies.
| Point |  |  |  |
|---|---|---|---|
| Season | One cool season | Longer season with shade | Many 30–45 day crops a year |
| Harvests | Two crops a season | Several crops a year | A crop every 30–45 days |
| Root quality | Forked, pithy roots in heavy soil | Straighter roots in prepared beds | Straight, crisp, clean roots |
| Pests | Aphids, flea beetles and sawflies | Insect net and traps keep pressure low | Insect net and traps keep pressure low |
| Soil diseases | Root rot and nematodes 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 radish
Radish is a fast root crop. Long white radish needs at least 30 cm of loose media, so it grows in troughs or bags, not in NFT channels.
Most usedTrough
Deep cocopeat troughs give long roots 30 cm or more of loose media.
Cocopeat grow bags
Deep grow bags with drip for smaller plantings.

White radish (mooli)
Long white roots for everyday cooking and salads, sold in bunches with leaves.
Climate and feeding
Ideal growing conditions for radish
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 radish |
|---|---|
| Season | Best in cool months; cooling needed in summer |
| Growing temperature | 10–25 °C; roots turn pithy and hot in heat |
| Relative humidity | 60–70% |
| Feed TDS | About 1,000 ppm |
| Feed pH | 6.0–7.0 |
| Plant density | Rows about 30 cm apart, plants 8–10 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 radish crop takes about 30–45 days from sowing to harvest.
- 01
Day 0
Sowing
Seed is sown straight into moist media in rows.
- 02
4–6 days
Germination
Seedlings come up fast; keep the media evenly moist.
- 03
Week 2
Thinning
Seedlings are thinned to 8–10 cm apart.
- 04
Weeks 3–5
Root growth
Roots fill out. Even moisture keeps them crisp and mild.
- 05
30–45 days
Harvest
Roots are pulled with their leaves as soon as they reach size.
- 06
After harvest
Clean-up
Media is loosened and the next crop is sown straight away.
Plant protection
Common radish 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 |
| Flea beetles | Small round holes in leaves | Insect net, check young plants often |
| Mustard sawfly | Leaves eaten to the veins | Insect net, hand removal, early control |
| Leaf spot (Alternaria) | Brown rings on leaves | Good airflow, no wet leaves at night |
| White rust | White blisters under leaves | Remove infected plants, good spacing |
| Pithy and forked roots | Hollow, hot or branched roots | Harvest on time, even watering, loose media |
Harvest and selling
Pick, grade and sell
Careful picking and grading decide the price you get.
- Pull on timePull roots as soon as they reach size; late roots turn pithy and hot.
- Keep the leavesRadish with fresh green leaves sells better in local markets.
- Wash and bunchWash, bunch by weight and keep cool and shaded until dispatch.
- Sell with live pricesTrack rates on Price Watcher and reach buyers through Buyers Connect.

Yes. Radish grows well under a polyhouse or nethouse in deep cocopeat troughs or raised beds, and is ready about 30–45 days after sowing.
Can radish be grown in hydroponics?
Yes, in deep cocopeat troughs or bags with drip. Long white radish cannot be grown in NFT channels.
Why is my radish pithy or too hot?
Late harvest, heat and uneven watering. Pull roots on time and keep moisture even.
How much revenue can radish 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 radish?
To local markets, hotels and retail chains. Use Price Watcher to track rates and Buyers Connect to reach buyers.
