i only buy dank, so there arent any seeds in it except for the rare little fuckers that ruin my day. and i basically take a nug and pack it into the bowl, thats if its the perfect size, other than that i break up a nug into 3 pieces and put them in.

usually if your pieces is nice and resonated you shouldnt have a problem with ash in your mouth. i just cleaned mine out so im shit outta luck... gotta smoke a bit more to get it back up to the point where it gets trapped inside.

you can get some nice reson hits off a pieces like that too if your desparate.
