Hash Leaves

Can someone tell me which leaves contain material for extracting hash with a bubbleator. Do the shade leaves that fall off after turning yellow or stems contain any material for hash. I know the best is probaly just the trim leaves close to the buds.

Depends upon the type of hash.
The highest quality sifted hash or ice+ water "bubble hash" will come exclusively from parts of the plant showing SURFACE RESIN STRUCTURES. So depending on strain, you will use any parts of the plant that you can see actual trichomes on.
Low-grade 'iso hash', which is a solvent extraction, can use any part of the plant. The downside is that you co-extract chlorophyll, and the product is gooey, green, and unpleasant.

If you really want to have a nice hash stash, use your prime trimmings and do a physical separation (for pics search 'stinky bubbles' on this site), and save the leftovers from that, plus your secondary trim pile, and do a cannabutter extraction for edibles. That's getting the MAX THC out of each harvest.
