When do you grind your medicine?

[mafioso420]

So... I know that for vaporizers to be fully useful you need to grind your herb really well. I purchase my medicine a few strains at a time and an 1/8th at a time. To save time I remove the buds from the stems and grind it all at once, so when I vape it's ready to go.

My question is... Should I be grinding it all at once? Or wait till before I vape to grind what I need?
Is there a benefit to waiting to grind?

Any help or suggestions would be appreciated.
