I thought I was asking a generic question.

I'm in the process of switching to a soil blend of mushroom substrate, trichoderma fungus and chitosan. even after reading what I could find on line, I'm still unsure what those last two things are.

I posted another thread asking if this was OK to use straight or whether I should combine it with other potting soil.

BTW, I tried sifting in some peat to that soil as a test and it prevented the container from draining.

thanks for the reply, Weezard. you are the first person who's said the pH wasn't important. the majority of posts and videos I've seen/read seem to place great importance on it. 40-45 yrs ago when I first grew, I didn't know much about pH (still don't) and nobody seemed to care. I'd like to go back to not caring, but as I say the posts on line, Carlos' book and more place great emphasis on pH.

I'm trying to catch up and all help is gratefully accepted.

thanks, again.
