Its best to use buds still wet too. Just trimmed bud. If you grind it you will end up having leaf matter in your hash.
Here is how I make my bubble:
I use fresh trim then cure the hash
for full melt:
I use only fresh close trim and buds. NO fan leaves (unless they are loaded with trichomes). I do not use a drill. I only lightly stir with a spoon for about 5 to 10 minutes. Then I let it settle for 20 to 30 minutes. I do not yield much this way but with many strains I can get full melt.
for good bubble (no melting just bubbles):
same as above but I use a drill or hand blender. I always yield way more this way but it just will not melt, but it bubbles real nice.

What I usually do is, first run aim for quality full melt then second run aim for quantity and just make bubble. Everyone has there own hash style. This is what I do and it works great for me. I love making hash.
