Warm Weather White Button Agar Plate (Agaricus bisporus)

Agaricus bitorquis, commonly known as the Warm-Weather White Button, is a robust species specially suited for high-temperature environments. Unlike traditional Agaricus bisporus, this strain fruits reliably at 24–30 °C—making it ideal for Sri Lankan climates where air-conditioned grow rooms aren’t practical or affordable.

This plate is produced under sterile conditions using nutrient-rich agar and colonised with vigorous, sector-free mycelium. Whether you’re running a compost-based operation or experimenting with tropical casing systems, it provides a clean, stable foundation for successful spawn and crop production.

What You’ll Receive

• 1 × 100 mm sterile agar plate colonised with Agaricus bitorquis
• Labelled with strain ID and pour date for accurate tracking
• Contaminant-free and freshly sealed; store refrigerated (2–5 °C) for up to 4 weeks

Recommended Growing Conditions

• Spawn run: 26 °C, 95% humidity, minimal light
• Casing run: 24 °C, 90% humidity, dark or shaded
• Fruiting: 24–30 °C, 85–90% humidity, moderate fresh air, 200–300 lux
• Substrate: Pasteurised straw-based compost enriched with poultry or cow manure, covered with peat or loamy casing

Why Cultivate Warm-Weather White Button?

• Performs where A. bisporus struggles—perfect for tropical climates
• Firm, dense mushrooms ideal for long-distance transport and extended shelf life
• Fruits under high CO₂ levels—reducing the need for intensive ventilation
• Strong market demand for familiar button-style mushrooms, even during warmer months

Ideal Use Cases

• Produce grain spawn for large-scale compost systems in warm conditions
• Inoculate shelf beds or tray systems without climate control
• Supply steady harvests to supermarkets, hotels, and food processors year-round
• Develop durable canned, frozen, or dried mushroom products for retail and export

This agar plate delivers a dependable, tropical-ready culture for commercial growers in Sri Lanka looking to expand button mushroom production with less reliance on cold-room infrastructure. Ideal for high-yield output on a small footprint, even in warm environments.
