Try this method:

With a loosley broken bud - set the volcano to 5.5

Vape one run at that temp - it should be light and very tasty but not that strong.

Set the volcano to 6.5 and run again

Now remove the buds and break them up into dust - after the first 2 vapes it should be dry and crispy.

Set to 7.0 and run again.

Anything after that is up to you - go to 9.0 if you want but you might not need to with this method.

Plus you can breathe vapour back into the bag and recycle.
