microbeman - any idea whether I am better off with multiple species of AM? In other words, considering I intend to maintain the living mulch in perpetuity, is it worth my while to source other AM species to apply to my containers?
my mix does have some mineral soil in it, maybe 17% or so
The only benefit to using multiple species is that 1/ researchers have made educated evaluations (also known as guesses) that various species have different roles and infection times, etc.
2/ distributers make more money selling you lots of stuff and you feel all puffed up because your mycorrhizal company has more 'stuff' than Joe Blow's mycorrhizal company. Many companies include Trichoderma species, even though there are some reports of it preventing mycorrhizal infection.
Essentially multiple species makes a great deal of sense if using indigenous fungi [growing your own myc.] but if you are trying to infect cannabis and clover, I'd suggest intraradices and Mosseae.
[some] Commercial hemp growers in Canada use only intraradices.
The best chance of successful infection is when planting seeds or prepping cuttings and planting rooted cuttings.
What is biotone? Is that the biotone plus starter stuff? It has various myc spores does it not? Did you really mean 600 propagules per pound?? That is scant.
