GMM uses vermiculite with good results in his mixes. I get good results with not using vermiculite in my mixes. GMM and I also have
very similar mindsets AFA as growing, mixes, just the whole deal.
Even when we're doing something different, we're doing it the same. Not gay, more like we have the same T-shirts (Been there, done that,......).
The point is, there's more than one path to the same destination, so don't obligate yourself to just one.

that's some funny shit man..
and as always so true..
Hey Wet, does the horse manure and rotted wood chunks work as an aeration component? If not, would you suggest I add some vermiculite and perlite?
remember the manure is sorta like a peat base that is a form of slow release nitrogen (has a lil P and K too, but not much)
i'd be concerned with the mix being a lil "hot"
a good idea is to maybe plant a cheap full-sun plant from a hardware store and see if it shoots off after transplanting.
i'd add a good amount of aeration to that mix, and also remember that wood ashes don't affect your mix after it's cycled, it does add phosphorus, and alters the ph a lil, but all those things are really short acting.
another thing is the promix is pre-limed (I think, been a while since I've seen a bag)
if using that much wood chunks you'll want to make sure they are charged, similar to biochar, if not they will sequester nitrogen from your mix as it ages (not a ton, but some)
Actually may not be a bda thing considering the amount of manure involved.
I would go towards a volcanic rock, perlite, or pumice aeration over vermiculite, reason being is if used in conjunction with the wood chunks your media may sty a bit moist.
water retention like that would be excellent for an outdoor grow, but may be a lil much for an indoor.
Hmmm... so after I think about it a lil more, I think to be safe, what i'd do is cut that mix (dilute it) with another bale of promix.
Better safe than sorry, to be honest I've never used horse manure so i'd have some trepidations on using that much.
Keep in mind i'm notoriously a light feeder, so I may just be a lil cautious
BUT you can alwaaaaays add more nutrients.. and NEVER subtract... like salt in a soup..
