I dont know how much bud was used. the tray is where i roll my joints, all the trichomes you see are from rolling joints.

I put the buds in the grinder and dump the ground up bud on the screen, and then roll my joint.

After a few weeks i lift the screen scrape up the trichomes and put them in the jar after having a few hits.

I usually have between 1-3 joints in a normal day. a joint is roughly .5 to 1 gram....
