The cake is dunked in water overnight to rehydrate and enable bigger and more flushes.
Hippie's Dunk tek is a simple yet effective way to extend the useful lifespan
of cubensis cultures such as PF cakes.
This tek should be used whenever the cakes/casings dry out. Also it can be given
after full colonization to replace water lost so far.
The tek itself is quite simple. It essentially consists of submersion of the cake/casing
underwater for 12 to 24 hours. Don't worry, that will not harm your cakes/casings.
One can even dunk cakes/casing that already have small pins safely. Just don't
overdo it, by 48 hours underwater they will be dead.
As for what kind of water to use, natural spring water is best but you can even
use it straight from your faucet if need be.
Temperature during the dunking should be be cool but not cold, refrigeration is not recommended.
Time spent dunking should be not less than 6 hours for minimal benefits. 12 hours
is about right for dunking in between flushes and at birth but 24 hours is the
maximum for full rehydration of nearly spent cakes.
There are at least 2 options for how to dunk. My prefered method is to dunk each
cake individually by placing it in a jar, filling with water, then screw on the
lid to keep the cake submerged. This way is good for small batches, and has the
advantage of keeping each cake isolated so no contaminants are spread from cake
For larger batches, you can simply place several cakes in a large pan or bucket,
cover with water and weigh down the cakes by placing a weighted down lid, plate,
etc. on top of the cakes.
After dunking, drain well, gently pat dry with paper towels, etc. and return it
to the fruiting environment.
