Bulk and standing orders
Larger farms place orders about two weeks ahead so we can let the bags fully colonize in our facility. For volume pricing, standing reservations, or custom strains, talk to us directly.
Common questions
Yield and handling
How many pounds will one block produce?
A 10 lb fruiting block typically produces 2–4 lbs of mushrooms across 2–3 flushes, depending on species, humidity, and airflow. High-yielding oyster varieties regularly hit the top of that range.
Do blocks arrive fully colonized and ready to fruit?
Yes. Every block ships fully colonized — the mycelium has completely run through the substrate before it leaves our lab. Introduce fruiting conditions (humidity, airflow, light, temperature) and pinning will begin.
How long can I store blocks before fruiting?
Fully colonized blocks can be held for 2–4 weeks at 35–45°F. For best results and the highest first-flush yields, fruit them within 1–2 weeks of delivery.
Ordering and shipping
What if blocks start pinning during shipping?
Early pinning in transit is normal and means the mycelium is vigorous and ready. Introduce your fruiting conditions as soon as the blocks arrive — those early pins become your first flush and yield isn't affected.
A variety I want is sold out. When does it restock?
Blocks are made to order and varieties rotate back in regularly. Email us with the variety you're after and we'll tell you the next available date, or reserve one from the upcoming batch.
Do you offer bulk pricing?
Yes. We work directly with commercial operations on volume pricing and standing order agreements. Contact us at info@MidAmMushrooms.com or call 419-283-4373 to discuss your needs.
