I mean, if it actually works, it would be turning plants into concrete, locking up their carbon. That would indeed be carbon negative. Probably a very inefficient way of doing so, if your only goal was turning plants into stored carbon, but if you're also getting zero-carbon shipping then it sounds pretty good.
