Planning hydroponic farm construction in Supaul? Supaul is a town in Supaul district, Bihar, home to about 65,000 people (GeoNames)[1][2], about 430 km from Kolkata. We have used the monthly climate for Supaul to plan a structure, a growing system and a crop calendar, so you can compare them with your own plot and buyers.
Climate for hydroponic farm construction in Supaul
May is the hottest month in Supaul, with average daily highs of about 39°C. January has the coolest nights, averaging 8°C.[3] The area gets about 1,165 mm of rain a year, most of it in June to September, peaking in July at about 317 mm. Average humidity stays at 75% or more in July to October, which raises the risk of leaf disease and slows evaporative cooling. Supaul sits about 34 m above sea level.[2] On the Köppen–Geiger climate map, Supaul falls in the humid subtropical with dry winters zone (Cwa).[4]

Which greenhouse suits Supaul?
For hydroponic farm construction in Supaul, the structure decides which months you can crop and what it costs to run. The heat in Supaul comes with dry air. In April to May, average highs reach 39°C while average humidity is only about 41%. In that dry air, wet pads can bring a 39°C May afternoon down to roughly 32°C inside a Fan & Pad polyhouse, which keeps herbs and vine crops going; lettuce will still struggle in the hottest weeks. For vine crops such as capsicum and cucumber, a naturally ventilated polyhouse with a shade screen works from February and September to November and costs less to run.
Plan for heavy rain in July (about 317 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank. A nethouse, the lowest-cost option, can grow hardy crops in February and October to November, when it is mild and fairly dry.
Hydroponic crops for Supaul
Based on Supaul's climate, the crops with the longest growing windows are coriander (11 months), mint (11 months) and basil (10 months). Coriander fits July to May with Fan & Pad cooling. These are the crops we would plan first for hydroponic farm construction in Supaul.

₹5,165Spending per person per month, urban Bihar, 2023–24[5]
430 kmto Kolkata, the nearest metro (straight line)
Urban households in Bihar spent an average of ₹5,165 per person per month in 2023–24, below the all-India urban average of ₹7,078.[5] Local demand in Supaul may be small for exotic greens, so plan where the rest of the harvest goes. Saharsa, about 30 km away, is the nearest larger market on our list.

Hydroponic farm construction in Supaul: FAQs
Can a hydroponic farm run all year in Supaul?
Yes, with the right structure. For Supaul we would plan a Fan & Pad polyhouse for leafy greens. Even then, lettuce is hard to grow in May to September, so plan another crop for those months.
Which polyhouse is best for Supaul?
With May highs of about 39°C and 47% average humidity in that month, we would start with a Fan & Pad polyhouse for leafy greens.
Which hydroponic crops should I start with in Supaul?
Going by the monthly climate, coriander, mint and basil have the longest growing windows. Confirm prices and volumes with buyers before you plant.
Does Kryzen build hydroponic farms in Supaul?
Yes. Our nearest site is our Chhatrapati Sambhajinagar warehouse, about 1,340 km away, and we have built 2 projects in Bihar.
Is there a subsidy for polyhouse or hydroponic farms in Bihar?
Yes. Protected cultivation projects in Bihar can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department. Check the current rate and area limit when you apply.
