Got to disagree with ya Big. I know for a fact that some of the new strains coming out are crazy high in potency. 25 years ago the thc levels were much lower than today’s cannabis. Plus the genetics are changing, high bred, cross strain, the development of cannabis is increasing daily. And trust me I know what TOP shelf cannabis is .
Take for example any random strain from back then. We will go with northern lights. The strain has been around since the early 80s. It's the exact same strain. Hasn't changed. They advertise it now as 33% thc. Genetically it's the exact same. Even the nutrients are the exact same, the lights, the times the pumps everything is still the exact same.
It didn't just all of the sudden jump up 10% in thc content. I smoked northern lights 25 years ago and I smoked it yesterday. It's the exact same.
A plant isn't going to all of the sudden get more THC just because 20 years has passed. Or because you bread it with some other plant when its thc content hasn't changed either. That's not how breeding works.
Its like trying to tell me, you can get a lion by breeding the right house cats. You just can't. The genome has to be there in order for it to be passed along.
Anyways. Since people have been using hydroponics, the shit is as strong as its gonna get. There is nothing new that would possibly change that.
