ICE cold dunking =(  13 02/09 07:55pm Snoopy

Hey guys, does anybody know if I should cold shock the lipa yai strain. I have dropped the temp by 6-8 degrees , but I know with some strains a good visit to the fridge is needed.

Any help would be great.

it prolly doesn't matter much,
cubies don't really need any 'cold shock'.
but it can't hurt,
so suit yourself.

I agree.. I never noticed much from cold shocking... but Dunking is beneficial

Besides... Most of these "strains" everyone says need a cold shock to pin originated in warm or tropical environments.. correct?

all cubies originated in the tropics.
and there's no cold shock in thai jungles,
yet they fruit just fine.
cold shocking is for other species, not cubies.

if one was to have a fridge used only for Dunks what temp would he set his fridge?

around 40-45*F i would think...
like a normal fridge.

I'm just posting this for shits and giggles. Although I've never heard of it I'm sure its been done before. So its winter, you're in Canada (or any other cold climate) and the casing layers on ten 2feetX1foot beds are colonized with mycelium. You want to cold shock 'em but you look in your fridge to find that its filled with beer, pizza, and leftover chinese food that you don't even remember ordering. There's no room and if there was its so dirty that anything you put in there would surely be overcome with contamination. What do you do? Put all your beds in the same room, open a window half way and close the door on your way out. 12 to 24 hours later, close the window. Viola, you've just cold shocked your beds with crisp, clean, cold winter air. Just make sure they don't get too cold. I've found cold shocking makes for better first flushes. Some people say it doesn't affect speed, yields, or pinsets but I've had good results.

Any feedback from anyone cold shocking casings between flushes??

I'm just curious whether it's worth the time, or if damage can be caused...


Also: any advise on how to keep my casings healthy throughout later flushes..

Cold shocking a casing is fine, although I, personaly, have found it unnecessary to initiate pinning.

As long as your casing does not freeze, a cold shock will not do damage. Try it both ways (with and without the cold shock) and see what you like best.

The best way to re-hydrate your myc for subsequent flushes is to re-case between flushes, IMO.

Re-hydrate through the casing layer itself.

You can also use a layer of damp perlite or vermiculite on the bottom of the casing to aid in rehydration.

You can "sweeten" your casing mix with a little extra lime on subsequent flushes to help fight off the green meanies.

I was thinking of dunking and cold shocking my cakes in the refrigorator before birth. My PF style half pints have been incubating at about 85 degrees and are now fully colonized, would dunking them at 45 degrees a few hours right before birthing (to a 75 degree terrarium) hurt the mycelium at all?

It's a great idea. More than a few hours though. At least 12, no more than 24.
