Common Questions
Everything you need to know about our farmer blocks
How many pounds of mushrooms 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. Simply 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 highest first-flush yields, fruit blocks within 1–2 weeks of delivery.
What if blocks start pinning during shipping?
Early pinning during transit is normal and means the mycelium is vigorous and ready. Introduce your fruiting conditions as soon as blocks arrive — early pins will develop into your first flush and yield is not affected.
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.
