There's another BIG reason to avoid the "all in one" microbial products like Great White, etc...
I'll explain it using a little analogy:
Mycorrhizal fungi are slow to infect roots, and relatively slow growing. The fastest I've heard of mycorrhiza becoming established In the rhizosphere after innoculation is about a week. That's why it's always recommended that your inoculate plants when they are very small in order to reap the benefits of mycorrhiza later in bloom (i.e. increased phosphorus availability and uptake). They are slow growing, slow establishing, friendly (plant-helping), organic matter-(and mineral)-munching creatures. For the sake of my analogy, let's call them buffalo (also which also happen to be organic matter-munchers that help plants by cycling nutrients).
On the other side, we have trichoderma. Trichoderma are a fast-growing, fast-colonizing fungi that FEED ON OTHER FUNGI (including mycorrhizal fungi). For the sake of my analogy, lets call them lions. Fast, strong, hungry, and opportunistic (this is why trichoderma are used for control of fungal diseases).
Now, let's say you have a blank slate; your pot of soil lacking microbiology, or a 100 square mile piece of African safari (depending on which side of the analogy you choose to sit on). If you wanted to restore these blank slates to diverse, complete, thriving ecosystems, would you start by releasing 166 buffalo (Great White has 166 propagules/gram of mycorrhizal fungi that associate with cannabis) and 313,124 lions (Great White has 313,124 propagules/gram trichoderma)? Probably not...
