Miracle Gro(wers) - a ? for you

I understand why you would use the organic vs. the normal MG potting soil due to the nutrients, BUT, do you add perlite since it does not contain any? Or is there some sort of aeration/absorption organic content to replace this?

theres little bits of perlite in the soil. I always add a bag when mixing my soil even if there already is some in there. It wont hurt the plant.

Potting soil is good to go straight from the bag.

perlite helps with the drainage
