I run coco not soil.One thing that I'm doing now is growing my blue dream in the high dollar name brand stuff and I've got a purple punch going right beside her and I'm using a generic with actually slightly better numbers and lo a behold the generic stuff is working better so I'm pretty sure that buying a name doesn't make a difference. Good dirt is good dirt it doesn't matter whose names on the bag
But my coco is better than your average soil because of the microbes & fungi in the root zone.
I add bokashi, frass and Dynomyco to feed my roots for me.
You don't need expensive soil for a good grow.
A little life added to the root zone works wonders.
Have you ever tried a microbial tea?
Stay safe
