I tried the "boil" method.
Someone on here mentioned it and now I can't remember who else does it, but when you boil the bark for at least 30 minutes and let simmer for another 30 minutes, you can cool rinse the bark with cold water and it's ready to use instantly. This makes the bark absorb more water faster than an overnight soak and makes the medium quicker to use than waiting over 24 hours.
