How much does it cost to set up a hydroponics system per square metre?

Hydroponics setup cost varies widely with the system type and whether it sits inside a polyhouse or open shed. A basic NFT or substrate setup can run in the range of roughly 1500 to 4000 rupees per sq m, while a fully climate controlled hydroponic unit with automation, dosing pumps and a polyhouse can cross several thousand rupees per sq m. The growing system is only part of it, you also pay for the protected structure, water treatment, nutrient dosing, power backup and a nutrient and pH monitoring setup. Costs add up fast because hydroponics is capital and equipment heavy. Subsidy support for hydroponics specifically is limited and inconsistent across states, often it is only the protected cultivation structure that is covered, not the hydroponic equipment. Treat low cost figures online with caution and get itemised quotes. Confirm current cost and any applicable subsidy with your state horticulture department before planning.
