cold shocking cubensis
    #4307600 - 06/17/05 03:18 PM (12 years, 2 months ago)

ok i've learned the lesson: never go off topic / always open a new thread. so here's the new thread:
someone said that cold shocking is only useful for wood loving species (eg azurescens), while a night in the fridge is useless for ps.cubensis and may even delay pinning. is that true? i've never read it on any tek, always coldshocked my cakes and had late pinnings...

Cold shocking slows vegetative growth (all growth) and thats about it. For difficult to pin strains (sitting in the fruiting chamber and just continue growing), a cold shock can be used to help stop growth...but usually 10 degree drop, with the fresh air and light is enough and a cold shock wont do anything in most cases. In some cases, the fruiting enzyme may already be in the network, and it stoped veg growth but people dont see pins, so they stick it in the fridge..that slows the fruiting growth and the pinning process.

So, IME, most of the time it does nothing, some of the time it hurts, some of the time it helps.

Cakes are different then casings IMO though...cakes get dunked..unlike casings...the verm in them absorbs water better then whole grains do so a dunking helps alot more with cakes then casings. And cakes are put in the fridge while they dunk, to keep growth of any kind happening while under water, because its likly that any growth happening, would be contams.

cold shocking  was once popular among PF style growers, but it was never provin to be of any benefit.
however, dunking does help  :thumbup: just not in the fridge :smirk:

ok thank you all!
so:
- never cold shock a cubensis casing,
- only cold shock cubensis PF cakes while dunking.

everyday i learn something new  :thumbup:

but scat says:

so if the water i use in dunking has h2o2 in it then i don't have to bother slowing down any growth in the cake, so i don't even have to cold shock a dunking pf cake, right?
i always dunk and roll my PF cakes, at birth and between flushes, normally i keep them in the fridge while they are dunked, but it seems that the fridge is useless since i put h2o2 in water.

This is quite likly the case. I havnt dealt with PF cakes but seems like the fridge isnt really needed..

I don't know. My buddy has done PESA and didn't cold shock and noticed that pinning was delayed a couple of days and not as many pins. I'd like some of the heavy hitters to comment on this... Diver, RK, Agar, etc.

Cold shocking P. Cubensis has never proved to be useful in my experience. If anything, it has stalled growth cycles to a point of almost no return the few times I've tried it. It's not something I practice. If people believe it works for them, and they are getting good results, then more power to them.

For the other species I've tried, cold shocking has been a good helper. Oysters and Shaggy manes seem to benefit from it.
