What temperature should a mushroom grow bag be?


The temperature required for growing mushrooms in a mushroom grow bag depends on the specific mushroom species you are cultivating. Different mushroom varieties have different temperature preferences for optimal growth. However, a general guideline for the temperature range during the colonization and fruiting stages is provided below

During the colonization or mycelium growth stage, which occurs after inoculation and before the formation of fruiting bodies, temperatures typically range from 75°F to 80°F (24°C to 27°C).

Once the mycelium has colonized the substrate, the fruiting stage begins. The temperature for fruiting varies among mushroom species, but it often falls within the range of 55°F to 75°F (13°C to 24°C).

It's important to note that different mushroom growing species may have specific temperature requirements outside these general ranges. Additionally, the substrate composition and environmental conditions can impact the temperature preferences. Some mushrooms may have specific temperature requirements for initiating pinning (formation of small mushroom pins) and for optimal fruiting.

Here are a few examples of common mushroom varieties and their general temperature preferences

Button Mushrooms (Agaricus bisporus)

Colonization: 75°F to 80°F (24°C to 27°C)

Fruiting: 55°F to 70°F (13°C to 21°C)

Oyster Mushrooms (Pleurotus spp.):

Colonization: 75°F to 80°F (24°C to 27°C)

Fruiting: 50°F to 75°F (10°C to 24°C)

Shiitake Mushrooms (Lentinula edodes):

Colonization: 75°F to 80°F (24°C to 27°C)

Fruiting: 50°F to 75°F (10°C to 24°C)

It's recommended to follow specific guidelines provided for the mushroom growing bags you are growing and to monitor and control the temperature within the desired range. Proper temperature control is crucial for successful mushroom cultivation, and variations can impact growth rates, yield, and overall quality.
