Another thing Jeff talked about in that show was re-using your soil and said something along the lines of: If you've grown a cannabis plant in soil, then that soil has now become 'Designer compost' for growing cannabis in because all the right micro-organisms are already in place.I'm definitely a believer in mycorrhiza fungi and its role in phosphorus uptake and plant growth. But yeah I'm not sold on the fact that I have to add it into my grow. It's been almost exactly a year since the last time I ran a grow with it and I haven't missed it at all. With all the learning and a couple new tricks in the hat this has actually been the best grow year I've had. But...I make my own worm castings, and my own compost (thermal and fungal), and I have access to awesome quality local compost when I don't have enough to meet my needs. I gotta believe some real life mycos are naturally going on with all that goodness. If I was stuck with a bale of promix, a bag of wiggle worm castings, and a handful of my favorite amendments...Then I would be adding mycos at transplant, and adding humic acid to my soil. But I dropped both and haven't missed either.
That or like you said...If our compost and soil is already full of plenty of uptakeable phosphorus...What the hell do we need mycos to improve the situation for? Maybe they're just for the poor bastards that don't have much phosphorus in their soil.
I'm sure you're re-cycling you're soil so it's possible that the required mycos spores are already in there and you're getting the desired infection without needing to add any more.............Just conjecture, I know, but it's plausible
