Review: Great bp - Makes good BP after proper milling
Review: Great potassium nitrate! - This is great potassium nitrate that has many uses. First up for me is to rot out an old walnut tree stump. It was a good deal for the money. Hope the potassium nitrate will speed up the process of disintegrating the walnut tree stump. Have to wait, over time, to see the effectiveness.
