Orchid cultivation in polyhouse and hydroponics
Grow orchids for cut sprays and potted plants under a shade-net house or polyhouse, in free-draining pots of charcoal, bark and husk. High-value flowers that last for weeks, with a farm designed, built and supported by Kryzen.
First spikes in 12–18 months
Plants yield for many years
NHB subsidy crop
Why protected cultivation
Can orchids be grown in a polyhouse?
Quick answer
Yes. Orchids such as Dendrobium and Phalaenopsis grow well under a 50–75% shade-net house or polyhouse. Plants are grown in pots of charcoal, bark and husk on raised benches, fed by fine drip or misting. Spikes come 12–18 months after planting and plants keep flowering for years.
Shade net protects orchids from harsh sun, and a roof keeps rain off, which spreads rot. Raised benches keep pots dry underneath and away from slugs, and fine drip or misting keeps humidity steady.
| Point |  |  |  |
|---|---|---|---|
| Season | Cannot grow in open sun | Shaded season only | All year under shade and humidity control |
| Harvest | Not possible in open sun | Fewer spikes | Spikes all year for many years |
| Flower quality | Sun-scorched, spotted flowers | Cleaner flowers | Clean, long-lasting sprays |
| Pests | Thrips, mites, scale, slugs and snails | Insect net and traps keep pressure low | Insect net and traps keep pressure low |
| Soil diseases | Root and crown rot in wet media | Still a risk; soil disease builds up over cycles | Low; free-draining media on raised benches |
| 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 | ₹2–4 lakh | ₹9–12 lakh | ₹13–20 lakh |
| Setup cost | Low | Medium | Highest; see your quotation and subsidy |

Where it grows
Best growing systems for orchids
Orchids grow on air, not in soil. Their roots need free-draining pots or buckets of charcoal, bark and husk, and frequent light feeding.
Most usedDutch bucket
Free-draining buckets or pots of charcoal and bark on raised benches.
Cocopeat grow bags
Bags of husk and charcoal for larger plantings.

What to plant
Types of orchids grown in polyhouses
Dendrobium is the main cut-flower orchid; Phalaenopsis sells as potted plants.
Orchid
Dendrobium sprays for florists and events, and Phalaenopsis potted plants for retail and gifting.
Climate and feeding
Ideal growing conditions for orchids
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 orchids |
|---|---|
| Season | All year under shade |
| Growing temperature | 20–30 °C; protect from cold below about 15 °C |
| Relative humidity | 60–80% |
| Feed TDS | About 300–500 ppm, given often |
| Feed pH | 5.5–6.5 |
| Plant density | About 8–10 pots per m² of bench |
| Shade | 50–75% shade net |
| Growing system | Pots or buckets of charcoal, bark and husk on raised benches |

Plant protection
Common orchids 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 |
|---|---|---|
| Root and crown rot | Soft, black roots and leaf base | Free-draining media, raised benches, do not over-water |
| Bacterial soft rot | Water-soaked, smelly spots | Keep leaves dry, remove infected plants |
| Thrips | Streaked, spotted flowers | Blue sticky traps, insect net |
| Mites and scale | Speckled leaves, crusts on stems | Check plants weekly, early control |
| Slugs and snails | Chewed roots and buds | Raised benches, clean floors |
