    Seed World is the best!

    I recently ordered potassium nitrate for my pecan trees. It was delivered as expected in great shape and on time. So glad seed world can supply things that I often cannot find locally.

    I do not know if products works yet, however it comes in a small self enclose bag, I would have preferred a container of some sorts for this. It is what I expected
