yeah ive seen it where it looked like they swept up the floor an dumped the seeds into the press they made the bricks with...like a vein of seeds  a couple inches thick all way thru the kilo...and another one comes to mind..it looked like they opened the wrapper for the kilo and jammed a wooden stick into the brick and reclosed the wrapper. .added a lot of weight(extra money) if someone did that too all the bricks while it was sittin somewheres in storage
