Fc temperature

So i know the jars should be keptt 80 degrees for optimum mycelium growth. and most p. cubensis do well with cold shocking. but what the temp supposed to be in the fruiting chamber?? ive read mid to upper 70's is best for pin growth, but that is not much of a temperature change, is that right? or is the initial drop enough of a shock? thanks for any advice.

There is no documented benefit to coldshocking cubes to my knowledge.....

I usually keep my jars at room temperature during colonization. I have never really noticed a difference incubating them other then more contams. Cold shocking is a process where the cakes are submerged in water and are soaked usually for 24 hours in a refrigerator. Cubensis mushrooms in my opinion do not respond well to cold shocking. The mycelium network actually produces heat. Now it does not produce much, but it is enough to raise the temperature of the jars above their ambient temperature. So those jars are probably at 81-82 degrees so introducing them into a fruiting chamber in the mid to upper 70's is fine. A temperature difference is only a minor trigger to initiate pinning. Fresh air and light are the most important. Your going to want to keep the air in your fruiting chamber very humid, near 100% humidity, and fan the air in the fruiting chamber at least 3-4 times a day. If your using fluorescent lighting make sure the color temp is between 5500K and 6500K.

when i grow my mushrooms im plannign on doing the whole process at room temp, so basically your saying it should be okay. Cool

room temp it is! that makes things easier, spank you!

Cold shocking is a very effective method for producing mushrooms. Not to mention it helps to rehydrate your substrates. However, you really only do this when you are using cakes.

With regards to the room temperature: mycelium will colonize at this temperature, but at a slower rate. Colonization requires more CO2, less O2. Fruiting on the other hand, happens from a good solid mycelial colonization and more O2.

Therefore, just taking the cakes or substrates out of the jar is enough to start. Combined with blue light (for added measure), you will get some pins atleast.

Room temperature is fine for both, just be wary of the gas exchange requirements for each stage of the cultivation process.

Yea the whole process can easily be done at room temperature. It may take an extra day or 2 to fully colonize the jars, but it's actually worth it. The lower temps create an unfavorable environment for bacteria and other fungi to develop.

Other shrooms DO benefit/need cold shock.... cubes show no preferance for this.... this has been well documented....
