Best organic mix for soil

Hello I am currently on my 3 harvest, Im growing indoor and wanted to know the best combination of things to get and the process to go through to get the best organic soil you could hope to grow with, I know bat guano as well as some worm castings are obvious ingredients but I am utterly inexperienced in any soil mixing processes, thanks in advance for the love fellow growers

Your kinda opening a top that probably has been discussed in so many other forums. You just need to look around and you'll find most of the answers to your questions about organic mixes.

you could buy a bag of soil with everything already in it. Try fox farms ocean forest or roots organic. They also have guano and castings in it plus some other great stuff.
