I’m from Western Canada and while our experience is very very far from the rest of NA’s…(none of our shit came from Mexico) one thing that’s definitely changed over the last few decades is the knowledge base of cannabis growers in general.

There are more cannabis specific products such as nutrient blends, pest, and environmental controls. Off the shelf products you can order online that used to be custom made or end you up on a list.

People understand pruning, topping, and branch lining. This becomes especially apparent when you compare amateur growers to intermediate and medical grade growers.

Than there’s the genetics being improved through breeding. .
