planning on choosing only 1 soil?

hi this post is going to help alot of people out for sure if i can get a decent reply. what kind of soil do i buy for growing weed? i live in canada so i cant buy foxfarm. im going to canadian tire or home depot can i buy any potting soil or does anyone know if a brand like miracle grow is good enough? im keeping it SIMPLE i wont be using perlite, building sand, worm castings, or any other custom mix gatherings from different parts from of the world. so hard to just get a straight answer these days. and yaaaa dont send me a generalized link to growing marijuana, im just looking for what soil to get i want to walk in the store and be out in 2 minutes THANKKS AGAIN!

See IF you can get DR. Earth or similiar; Organic Soil with Mycor...(those natural soil=probiotics!) A well thought out Soil like this won't be available everywhere, but search and you'll find-it! This is my 1st Indoor (going into 13th week) and the Soil mentioned has been very successful, and i have not attracted any bad bugs, just mini-mini-fly's and they seem to benefit the plant! Thought about bringing in a Praying Mantis i found, but don't seem to need him. Oh, using "OneNess" by Humboldt Nutrients as Feed/H2O-2-3 times daily; 3 small scoops;maybe 3 ounces each, AND The Exhale; CO2 Bag=effective and Cheap; Running One 400W using MH and just introduced the SPS bulb, using Electronic Energy Saving Ballast with 4X4X76" Grow Tent.
