Hey AutoWanKenobi. I´ll be as straight forward as possible for you (great name by the way!)
No one can tell you what the absolute best soil to use is as there is no one correct answer. Some people like to build their own soils that will only require water for the whole grow, others prefer an inert medium like coco where you have absolute control over exactly what your plant receives, and yet more people (me included) like to buy bags of quality soil from grow shops or garden centres and add things like perlite to them to improve aeration and drainage.
If there was one absolute best soil to use, then everyone would be using it. The best thing to do is to work out what you have available to you easily, and how best to utilise that, for example I can get biobizz light soil easily so thats what I use. I add about 30% extra perlite to it, and if I´m feeling fancy maybe some worm castings too, and it works great. Its not necessarily better than other soils, but it works well for me, and thats what you need to do is find out what will work well for you!
If you can list some soils that you can get hold of easily, then maybe people can give you pros and cons of each one?
