Planning hydroponic farm construction in Buxar? Buxar is a mid-sized city in Buxar district, Bihar, home to about 1 lakh people (GeoNames)[1][2], about 560 km from Kolkata. This guide works from Buxar's own monthly climate to suggest the protected structure, the hydroponic system and the crops to start with, and the months each crop is likely to do well.
Climate for hydroponic farm construction in Buxar
May is the hottest month in Buxar, with average daily highs of about 43°C. January has the coolest nights, averaging 8°C.[3] The area gets about 891 mm of rain a year, most of it in June to September, peaking in July at about 263 mm. Average humidity stays at 75% or more in August to September, which raises the risk of leaf disease and slows evaporative cooling. Buxar sits about 55 m above sea level.[2] On the Köppen–Geiger climate map, Buxar falls in the humid subtropical with dry winters zone (Cwa).[4]

Which greenhouse suits Buxar?
For hydroponic farm construction in Buxar, the structure decides which months you can crop and what it costs to run. The heat in Buxar comes with dry air. In April to June, average highs reach 43°C while average humidity is only about 32%. In that dry air, wet pads can bring a 43°C May afternoon down to roughly 31°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 November and costs less to run.
Plan for heavy rain in July (about 263 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank. Sunlight peaks in May at about 6.6 kWh per m² a day, so add a shade screen for leafy greens in the brightest months. 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 Buxar
Based on Buxar's climate, the crops with the longest growing windows are mint (10 months), coriander (9 months) and basil (9 months). Mint fits July to April with Fan & Pad cooling. These are the crops we would plan first for hydroponic farm construction in Buxar.

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 Buxar may be small for exotic greens, so plan where the rest of the harvest goes.

Hydroponic farm construction in Buxar: FAQs
Can a hydroponic farm run all year in Buxar?
Yes, with the right structure. For Buxar 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 Buxar?
With May highs of about 43°C and 29% average humidity in that month, we would start with a Fan & Pad polyhouse for leafy greens.
Which hydroponic crops should I start with in Buxar?
Going by the monthly climate, mint, coriander and basil have the longest growing windows. Confirm prices and volumes with buyers before you plant.
Does Kryzen build hydroponic farms in Buxar?
Yes. Our nearest site is our Chhatrapati Sambhajinagar warehouse, about 1,090 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.
