I always wanted to, but the prices have been too high for me.
I'm hoping that, if I can make my soil into something that favors healthy roots, they will find a spore of the root fungi they need and multiply it.
Some microbiologist once said something like "everything is everywhere - growing conditions determine what predominates".
But I always wanted to get involved in the root-fungus symbiosis by adding spores. One company advertised its product as better than anyone else's because THEY sold spores that had great viability after storage. Other companies, they claimed, just sold dried, powdered fungal hyphae that mostly died on the shelf before purchase.
