If the mycelium becomes warmer than the temperature of the room, it can overheat and weaken, or even die, killing your fruit production. Can Raising the Temperature Cause Problems?Ĭaution is advised with this strategy because the mycelium itself creates heat as it breaks down the substrate for consumption. This imitates the increase in ambient temperature that the mushrooms experience after breaking through the surface of the rotting wood or soil, signaling to the mycelium that the conditions are right for fruiting. Raising the temperature slightly after the mycelium has colonized the substrate can prompt the growth of primordia, the beginning stage of fruiting. Mushrooms that have evolved to grow on rotting wood prefer wood chips, sawdust, damp logs, straw, or even cardboard, and other varieties that grow wild on forest floors might tolerate used coffee grounds, spent grain, or corn cobs. Here are some types of mushrooms and their biological efficiency rates: Mushroom Type Biological Efficiency Rate Shiitake 100-200% Lion’s Mane 90-140% Reishi 80-120% Pink Oyster 100-170% King Oyster 100-150% How Does the Substrate Influence Fruiting?Įach variety has a preferred substrate, and choosing the ideal one for the variety you’ve chosen to grow will maximize your fruit production as well as how quickly fruiting will occur. A mushroom variety that produces one pound of fruit for one pound of substrate would be calculated at 100% efficiency. Here are some types of Oyster mushrooms that have high yield rates: Type of Oyster Mushroom Time to Fruiting from Inoculation Pearl 3-4 weeks Yellow (also known as Golden) 2-3 weeks Pink 3-4 weeks Blue 4-5 weeks Phoenix 3-4 weeks King 3-4 weeks Which Mushrooms Have the Greatest Efficiency Rate?īiological efficiency is calculated by measuring the pounds of fruit produced per pound of the dry substrate over multiple flushes. The mycelium can produce three rounds of crops before it becomes exhausted and the substrate must be flushed, which means growing Oyster mushrooms will require less time and labor than many others. Oyster mushrooms are the variety that has the highest yield because they form a mycelium and fruit as quickly as 20 days from inoculation to fruit.
How Long Do I Have to Wait to Try To Prompt Fruiting? Should I Care More About Yield or Efficiency?Īre you more concerned with producing the most mushrooms possible in the least amount of time, or growing most mushrooms per pound of dry substrate? That is the difference between yield and efficiency, and there are different strategies for either goal.
