Planning hydroponic farm construction in Kollam? Kollam is a large city in Kollam district, Kerala, home to about 4 lakh people (Census 2011)[1], about 470 km from Bengaluru. Below we use the town's monthly temperatures, humidity and rainfall to work out which structure fits, which crops to grow and in which months, before you spend on construction.
Climate for hydroponic farm construction in Kollam
March is the hottest month in Kollam, with average daily highs of about 35°C. January has the coolest nights, averaging 21°C.[2] The area gets about 2,052 mm of rain a year, most of it in April to November, peaking in October at about 327 mm. Average humidity stays at 75% or more in April to December, which raises the risk of leaf disease and slows evaporative cooling. Kollam sits about 3 m above sea level.[1] On the Köppen–Geiger climate map, Kollam falls in the tropical monsoon zone (Am).[3]

Which greenhouse suits Kollam?
For hydroponic farm construction in Kollam, the structure decides which months you can crop and what it costs to run. In Kollam the heat comes with humidity: during February to April average humidity is about 68%. Wet pads cool much less in humid air: on a typical March afternoon they would only bring 35°C down to about 31°C. So we usually start with a tall naturally ventilated polyhouse with wide roof vents, insect net and a shade screen. A Fan & Pad polyhouse still makes sense if buyers need lettuce through the hottest months, but expect a smaller temperature drop than in dry inland towns.
Plan for heavy rain in October (about 327 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank. Sunlight peaks in March at about 6.4 kWh per m² a day, so add a shade screen for leafy greens in the brightest months.
Hydroponic crops for Kollam
Based on Kollam's climate, the crops with the longest growing windows are basil (10 months), cucumber (10 months) and mint (9 months). Basil fits April to January in a naturally ventilated polyhouse. Strawberry and parsley are hard to time here, so we would leave them out of the first season. These are the crops we would plan first for hydroponic farm construction in Kollam.

Hydroponic farm construction in Kollam: FAQs
Can a hydroponic farm run all year in Kollam?
Yes, with the right structure. For Kollam we would plan a tall naturally ventilated polyhouse with wide vents and insect net. Even then, lettuce is hard to grow in February to June, so plan another crop for those months.
Which polyhouse is best for Kollam?
With March highs of about 35°C and 65% average humidity in that month, we would start with a tall naturally ventilated polyhouse with wide vents and insect net.
Which hydroponic crops should I start with in Kollam?
Going by the monthly climate, coriander, basil and mint have the longest growing windows. Confirm prices and volumes with buyers before you plant.
Does Kryzen build hydroponic farms in Kollam?
Yes. Our nearest site is our factory and master warehouse at Degaon, Wai (Satara), about 1,050 km away.
Is there a subsidy for polyhouse or hydroponic farms in Kerala?
Yes. Protected cultivation projects in Kerala 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.
