AC Climate-Controlled White Button Mushroom
Commercial protected cultivation blueprint including verified plant density, climate thresholds, stage-by-stage water soluble fertigation recipes, and 50% NHB/MIDH subsidy eligibility.
Insulated PUF Panel Climate Chamber with AHU & Chiller
Engineered to maintain optimal thermal stability, humidity control, and vector exclusion for AC Climate-Controlled White Button Mushroom.
- 365-day year-round production independent of external outdoor weather or seasonal monsoon
- Vertical space utilization: 5 to 6 rack tiers achieve 5x output per square meter of building footprint
- Requires pasteurized compost (wheat straw/paddy straw + poultry manure + gypsum) and casing soil
- Commands steady wholesale rates of ₹110 to ₹160 per kg in modern food retail and hospitality chains

Precision Fertigation Schedule (100% Water Soluble Fertilizers)
Dosage rates per 1,000 sq.m unit to prevent nutrient lockouts and maximize marketable produce weight.
| Crop Growth Stage | Duration | Recommended WSF Grades | Daily Dosage (1000m²) | Nutrient Purpose | Practical Instructions |
|---|---|---|---|---|---|
| Spawn Running Phase | Day 1 to Day 14 | Zero chemical fertilizer; nutrition entirely from Phase-II pasteurized compost | Compost C:N ratio balanced at 16:1 with 2.2% total nitrogen | Mycelial colonisation through compost mass in closed chamber | Chamber temperature kept at 24°C with zero fresh air dampers opened (high CO2 > 5000 ppm). |
| Casing & Temperature Shock (Pinheading) | Day 15 to Day 25 | Sterilized casing layer (peat moss/decomposed coir pith + calcium carbonate chalk) | 4 cm casing layer applied evenly over colonized compost | Moisture retention and physical matrix for mushroom pinhead formation | Trigger pinheading by dropping air temp to 15°C and exhausting CO2 to below 1000 ppm with fresh air. |

5 Golden Polyhouse Management Rules for AC Climate-Controlled White Button Mushroom
Use only Phase-II tunnel-pasteurized compost to guarantee zero weed mould fungi and nematode cysts.
Maintain casing layer moisture with fine rose nozzle water sprays; avoid over-saturating which suffocates pinheads.
Twist mushrooms gently at harvest with base trimmed cleanly; never leave damaged stubs on the casing bed.
Pack immediately in 200g breathable perforated BOPP punnets and store in cold room at 4°C.
