Hey anonymousgrow I dunno how to +rep but thanks for the awesome info
What about reusing soil? If trichoderma is not root dependent, I would have concerns. I see it's listed as a fungicide.I think He is cautioning you from using a mycorrhizal innoculent that contains 100x trichoderma than, say, glomus intraradices. The trichoderma will take off and start eating other fungi as soon as it's in moist soil unlike the mycorrhizae which needs plant roots to live on. It's possible that the trichoderma is just going to eat the mycorhizzal fungi before it ever begins to take off.
Well it looks that there are diferent kinds of trichoderma...

What is true from my experience is that there are many products sold as beneficial mycorrhizal fungi to use with plants that don´t work at all.
The last product I bought ( canna related, made in spain) ended up on the compost pile.
This stuff looks like a web of super fine roots going through the soil.
