I would have to look - You got me on that one..
I do know that there are like 8 different cannabinoids found in seeded that unseeded does not have. It's said by those that prefer the seeded. That it makes it more intense and lasts longer....I am speaking on full spectrum and UVB grown plants - seeded and unseeded....
Sadly, even if it's true and can be proven.....You won't be seeing seeded cannabis on any shelves or setting sales records either.
It's kinda like the
fact that if properly harvested in steps. The smaller buds are stronger and measurably more potent.....Not many really know that. Even less believe it.....I think U-Ben said something about that in his "Lower buds don't need light to grow big" thread. He got ridiculed to death for that statement. Thing is,
it's true!
