i have a section of my yard that is not real pretty and i just bury it there. i only grow around 4 plants at a time so i don't think this would work for someone who grows shitloads. as far as the dirt i just let the pots sit for a few weeks after harvest and then break up the root balls and use it to bury the stuff. i water it so it settles. it must be so fertile back there lol. also if you can pack some of it in smaller sized plastic grocery bags you can just go "vaccuum your car" and ditch it in the trash. i have done this twice. lol i have even gone through the charade of pretending to put money in and acting like the vaccum is broken so i can just leave. just a show in case those stupid cameras actually work.
