Short answer (typical ranges in Indonesia, Sept 2025):

• Hobby / home kits: roughly Rp 4.5–8 million per unit (small prefabricated kits) or about Rp ~100k–500k per m² depending on size and finish. (peluangusaha.kontan.co.id)
• Basic film/poly tunnel (commercial, low‑automation): about $8–$15 / m² → ~Rp131k–Rp246k/m² (mid‑Sep 2025 USD→IDR ≈ 16,400). (indonesian.agriculture-greenhouses.com)
• Mid‑range multi‑span (better frames, PC panels or single glass, moderate automation): about $18–$35 / m² → ~Rp295k–Rp574k/m². (indonesian.alibaba.com)
• High‑end glass / Venlo, fully automated turnkey commercial greenhouses: about $35–$60 / m² → ~Rp574k–Rp984k/m² (can be higher where insulation, heating, LED lighting, CO2 dosing and full environmental control are included). (lightdeprivation-greenhouse.com)
• Container/vertical controlled systems (plug‑and‑play CEA): examples on the market show full container systems quoted in the hundreds of millions IDR (e.g., ~Rp 328M–492M per container unit). (indonesian.alibaba.com)

Why prices vary a lot

• Materials (steel frame vs bamboo/wood; PE film vs polycarbonate vs glass).
• Level of automation (manual vents vs sensor + PLC + remote monitoring + dosing).
• Climate control needs (fan‑pad cooling, heating, dehumidification, LED lighting, CO2).
• Site works, local labor, shipping/import costs, taxes and permits.
• Scale: unit cost usually falls as area increases (manufacturers often quote lower $/m² for large orders). (id.greenhousevendor.com)

Other costs to budget (recurring and one‑offs)

• Installation and commissioning (significant for smart systems).
• Electricity (LEDs, fans, pumps, HVAC), water and nutrient supplies.
• Maintenance, spare parts, and software/subscription for some control systems.
• Seeds/seedlings, labor and packaging/marketing for commercial scale. (Local case studies show greenhouse structures meaningfully raise upfront investment and can reduce margins unless crop and price structure support it.) (trubus.id)

Context in Indonesia

• Indonesia is seeing public and research investment in smart greenhouses (e.g., BRIN collaboration to build a 2,000 m² smart greenhouse in Bogor), which is expanding local experience and supply. This also means more local contracting options may become available. (lestari.kompas.com)

Quick practical guidance

1. Define your target: hobby, year‑round leafy greens, tomatoes/fruiting crops, or high‑value herbs/berries — crop choice changes required equipment.
2. Decide scale (m² or number of container units).
3. Get at least 3 local quotes (include breakdown: frame, cover, automation, irrigation, installation, shipping). Use local installers to avoid high import/ship costs. (Many suppliers will quote in $/m² — I used mid‑Sep 2025 USD→IDR ≈ 16,400 for the conversions above.) (wise.com)

If you want, I can:

• convert any of the USD/m² ranges above to a specific IDR total for a site size you give, or
• find and compare 3 Indonesian suppliers/contractors (with recent price quotes) for the greenhouse type you plan to build.
