Hard to give you exact percentages, since I recycle a fair amount of the mix, and it has various brands in it.
Guesstimate, by volume:
20 % perlite (big bag of Aztec perlite, cheap at the hydro store, especially if it's an open bag)
10 % coco coir (blocks purchased in previous seasons, still lingers)
30 % Peat moss (at Home Depot, 14 USD or so for the bale, label used to be white, now it's black)
25 % veg compost-worm castings-sheep manure (my own, and other sources)
The rest fine bark-small wood chips (many sources)
Amendments Alfalfa Meal, Crab Meal, granulated fertilizer strip, dol lime, drench w favorable microbiology. Guanos make it in there too sometimes
