The short answer

How much does an 18×60 ft mushroom grow room cost?

On MushroomWale's rate card v2.92 (Oct 2026) the Daikin 10 TR climate package for a 18×60 ft room costs ₹3,19,295 + 18% GST. The room is built from PPGL PUF panels at ₹1,535/m² (60 mm shared walls), ₹1,750/m² (80 mm outer walls) and ₹1,875/m² (roof), and holds 2,500 bags for about 5,000 kg of button mushrooms per cycle. Racks, electricals and civil work are quoted per site, so a complete room price comes from the instant quotation.
