On the topic of grinding, I find anything works as long as you have the E-pic! As the bowl drags on I end up using it as a little knife and dicing up my buds finer and finer and can pull many extra hits from each bowl!
If I start ground up, the hits come hard, fast, and milky. There are less of them but they're dense.
Sometime I toss in a full nuglet ad just session on him for a while, pulling flavorful rips first, slowly poking at him till he mulches himself up, then come the milk shots!
Convection is king!
Heres a video a made on New Years, just an unground 0.065g hunk of some home-grown deliciousness my grower calls "the Funk". Tastes like pine cones! Super dank!

Note: the hits continue for a few more after this, albeit a bit stale.
