Saltpeter and tree stumps
I’ve heard a lot of people saying you can get saltpeter from stump removers if you want to make BP. I have a stump maybe ten inches in diameter, left from the tree I cut, that was growing out of a wall. I also have some saltpeter. How effective would it be if I drilled a one inch diameter hole in the stump and filled it with saltpeter? I guess I should cover it with plastic to keep the rain out. Will it be as effective as commercial stump removers or should I simply buy the commercial stuff?
Thanks
