Cold Shocking

Ive read alot lately how this is not good... but this is from RR's notes Quote:
You should soak in the refrigerator to avoid bacteria buildup in the anaerobic environment under water. COLD SHOCKING
So i guess using cold water is a no no, but wont the water eventually get too cold in the refrigerator?
then he says this...Cubensis benefit NONE from cold shocking, as they are a hot tropical species; Cold Shocking is used for cold climate edible mushrooms. COLD SHOCKING
aren't these contradicting statements?

Techniques in this hobby are constantly changing and being updated. I don't even think RR recommends putting cakes in the fridge while dunking anymore. The reason that people used to dunk in the fridge was to prevent bacterial buildup (not to cold shock), but it's actually been shown that it delays pinning by a few days. Anyways bacterial buildup while dunking isn't so much a concern as it used to be. Chlorine present in tap water should be sufficient.
As to the last two lines of your post... i don't see how thats contradicting. Cubensis benefit none from cold shocking, and species of edible mushrooms from colder climates do. whats contradicting about that?

Stick around this forum for 5-6 years...
You'll contradict yourself a few times too.
IMO, I agree w/ RR.

Yes, they are contradicting and can be confusing.
I did cakes once, and when I did them I dunked them in the same 1/2 pint jars, in the fridge overnight.

Just the act of dunking at room temperature creates a cool down (temp drop) in substrate. I've found though aggressive substrains transition to generative growth can be hastened with a 24hr dunk in the fridge. It just slows the vegetative growth quicker and the substrate warms right back up quick enough. I've actually seen fruiting sooner rather than later initially but once the substrate is fruiting a fridge dunk will really set you back and even stall growth.

So I've finally got my first successful batch with the BRF tek. I've
been researching a bit more, and i couldn't find any answers on this
particular topic. So I thought to myself, "Hell, let me bring this
topic back up once more." COLD SHOCKING. As far as I've learned from
researching cubensis does NOT benefit from cold shocking. Rehydration
with water at room temperature overnight will be successful, BUT I
still have one more question. Does rehydration and using the SAME
cakes repetitively cause the the fruit bodies to become weaker in
potency? Does it make the cake more susceptible to contaminations?

When I said using them repetitively I was talking about dunking them for
rehydration. So yeah you helped answered my question. Then how do I know
when i am done with the cakes? The fruit bodies will just stop growing
from the cakes?
