So for another example. Take skunk #1
It first came out in the mid to late 70s.
This is THE EXACT SAME STRAIN as existed back then. Hence the #1. It hasn't changed in like 40 years.
Well now, let's look at their advertised thc content.
Skunk #1 strain has a very pleasant taste that is a combination between woody and fruity and sweet. Skunk #1 is very beneficial on a variety of medical disorders.

Oh, would you look at that. %22.
The exact same stuff my dad got busted growing back in the day.
How shocking is that? If you dont know what you're doing and you just willy nilly toss seeds in dirt and water it, you get a pretty low thc yield.
But if you know what the hell you're doing, and bring that same seed inside, under lots of good light, with nutrients and basically as much everything as the plant will take. You get a very different animal.
How could it be a strain from 40 years ago can give you 22% thc? The strain didn't change. So what did?
Now do some research, see what happens if you grow any of those old strains properly.. the exact same thing.
Most people didn't know how to grow back then. But some did, I did, everyone I know did. And still does now. Talk to someone who's been growing properly for 20 years, ask them.
Nothings changed, more people just learned how to grow properly. That's it.
