I've got maybe a tsp. of stuff I've scraped off the tray. If I had more smoke/self control I'd have more lol. I'd like to buy or build a little box sometime with sections of different sized screens. A shaker box or something? Could be making sh*t up at this point lol! I've never had too much luck with grinders that have the screen. It always seems to get clogged and noting falls through...or I just had crap smoke lol.
