Golden Chestnut Grain Spawn
Gourmet Golden Chestnut spawn, and an excellent cool-season grow.
Two ways to order:
- Made fresh to order (ships in 3–4 weeks): We inoculate your bag after you order, so it arrives fully colonized and at peak vigor instead of aging on a shelf.
- Ready to ship (ships in 1–3 days): When we have a fresh batch on hand, you can skip the wait. If it shows sold out, choose made fresh to order.
Golden Chestnut (Pholiota adiposa) is a true culinary standout: a firm, almost snappy texture, a nutty-sweet flavor that holds up in sautés, roasts, and stir-fries, and glossy golden caps that look as good as they taste. It's also a cool-weather fruiter, which makes it an excellent fall and winter grow.
Includes WeMush tracking: Every order ships with a QR code linked to WeMush, our cultivation tracking platform. Scan it to view specimen details, log observations, and follow your grow, free with any Mush Ohio purchase.

Cultivation guidelines
- Substrates: Sterilized supplemented hardwood sawdust or Master's Mix (soybean hulls and hardwood sawdust).
- Colonization: 70–75°F (21–24°C) in the dark. Golden Chestnut is steadier than oysters, so allow extra time for full colonization.
- Fruiting: Cool temperatures of 50–65°F (10–18°C), 85–95% humidity, indirect light, and plenty of fresh air exchange.
- Harvest: Pick clusters while caps are still convex, before they flatten fully.
These are general guidelines; optimal conditions vary with your setup.
Storage and handling
- Inspect the bag on arrival for damage or contamination.
- If not using right away, refrigerate at 35–40°F (2–4°C).
- For best results, use within 1–4 weeks of receipt.
