aaahhh, i geddit ..
totally understand the "i gotta try to make this stuff" point of view
i just wasn't sure if hadn't seen the other "pre made" alternatives.
i learned about the time period years ago when you could ask the good
folks at TPF to send you "the freshest - stuff" and they would say it takes 2 weeks
and at the end is when it is crushed .. i have no idea what it is, how it is made
or much else, it just seems to take its time ( drying out ? ) before it can be used.
and then it has to be used before it becomes use-less ..
have fun with your mad-science
