Hydroponic farm construction in Rafiganj: nFT flatbed hydroponic farm with lettuce, built by Kryzen

Planning hydroponic farm construction in Rafiganj? Rafiganj is a small town in Aurangabad district, Bihar, home to about 36,000 people (GeoNames)[1][2], about 450 km from Kolkata. This guide works from Rafiganj'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 Rafiganj

May is the hottest month in Rafiganj, with average daily highs of about 43°C. January has the coolest nights, averaging 9°C.[3] The area gets about 1,000 mm of rain a year, most of it in June to September, peaking in July at about 279 mm. Average humidity stays at 75% or more in July to September, which raises the risk of leaf disease and slows evaporative cooling. Rafiganj sits about 89 m above sea level.[2] On the Köppen–Geiger climate map, Rafiganj falls in the humid subtropical with dry winters zone (Cwa).[4]

Which greenhouse suits Rafiganj?

For hydroponic farm construction in Rafiganj, the structure decides which months you can crop and what it costs to run. The heat in Rafiganj comes with dry air. In April to June, average highs reach 43°C while average humidity is only about 34%. 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 October to November and costs less to run.

Protected structures to compare

Plan for heavy rain in July (about 279 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank. Sunlight peaks in April at about 6.7 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 Rafiganj

Based on Rafiganj's climate, the crops with the longest growing windows are basil (10 months), mint (10 months) and coriander (9 months). Basil fits February to November with Fan & Pad cooling. These are the crops we would plan first for hydroponic farm construction in Rafiganj.

Hydroponic farm construction in Rafiganj: FAQs

Can a hydroponic farm run all year in Rafiganj?

Yes, with the right structure. For Rafiganj we would plan a Fan & Pad polyhouse for leafy greens. Even then, lettuce is hard to grow in May to August, so plan another crop for those months.

Which polyhouse is best for Rafiganj?

With May highs of about 43°C and 30% average humidity in that month, we would start with a Fan & Pad polyhouse for leafy greens.

Which hydroponic crops should I start with in Rafiganj?

Going by the monthly climate, basil, mint and coriander have the longest growing windows. Confirm prices and volumes with buyers before you plant.

Does Kryzen build hydroponic farms in Rafiganj?

Yes. Our nearest site is our Chhatrapati Sambhajinagar warehouse, about 1,100 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.
