cold shocking..
    #2976476 - 08/07/04 09:34 PM (12 years, 11 months ago)

can someone give me a link to any articles about cold shocking, or explain to me what it is that makes the cake pin by refridgeration? it seems to me like the cold tempature would jsut slow down the process?

most ppl say it is no good for pinset.... its good for long time dunking as it slows contams (they wont start).

after the cake is 100% colonized, you drop the temp down a few degrees and this will help the mycelium know to start pinning =)
if your cakes are in an incubator you can take them out and the temp drop shoudl be enough. provided your iuncubator is at approx. 85-86 degrees and your room temp is about 75

There are many species of mushroom which will not fruit without a cold shock to start them up. Cubes arent one of them so the slight drop in temps from inc. to fruiting chamber is usually sufficient unless you have a particularly stubborn myc,or are unable to drop the temps down around the low 70's.

Acually temp play a much bigger roll than you realize :wink: Cubies pin much more prolific with optimum temps and yields are directly proportionated. Some peeps are just satified with low yields :wink: which is fine because there just so damn beautiful anyways!!!!

optimum temps are 75 when fruiting 85 when incubating... the 10 degree drop is plenty fine..... I have seen a lot of people doing research on it say that the cold shock in a fridge doesnt really help. However if you mean cold shock from 85 to 75 then yes.........

Personally, I incubate and fruit at room temperature. Cold shocking does nothing, as said above for cubies. Stamets mentions it in his books because it's essential for certain strains of edibles.

Also as said above, when dunking, put the cake/casing in the refrigerator to keep bacteria from forming as quickly.

There is a cold shocking contest over at mycotopia to put to rest the fact of fiction. Give it a read. Interesting stuff. http://www.mycotopia.net/discus/messages/100158/139018.html?1091369066

I think the cold shocking is only useful if you have trouble keeping your temps down.

All people are doing by coldshocking is breeding mushrooms that are more likely to require it. That's definitely not the way we want to go.

Very true - cold shokcing for cubies is completely unnecessary - if you expose a colonised agar dish of cubensis to light without shocking or with it, it will pin in exactly the same way.
Really only cold weather mushrooms require a cold shock.

Before you all get on the bandwagon pinning requires triggers right?  For cubies Light, drop in co2 levels (FAE) and a drop in temps are the major ones, here the drop in temp is the "cold shock" it doesn't have to be in the fridge but the fridge does make dropping the substrates core temp quicker and if you are dunking then it ain't so bad to do it at the same time IMHO. And really cold weather mushrooms are the exact same way they're "cold shock" is simply a drop in temps. Of course cubies will fruit in many conditions as well as not. I've had many a very prolific flush using casings which were not "cold shocked" in the fridge but every single last one had a good drop in temp. :wink: Just my $.02 :laugh:
Roger Rabbit those logs were incubated and fruited at the same temp?
