The previous owner of our house dumped these hydroponic clay pellets in a corner of the yard:
I'm estimating around 500 gallons worth or more, based on what I have already shoveled into bags. Does anyone know of alternative uses for this stuff? Landscaping, use in french drains,...? I would rather not have to junk it (and it's heavy in bulk). If anyone has ideas (or thinks they could clean it up enough to be useful for their own purposes...), please advise!
Thanks in advance,
Jason
