Is our herb really multiple times more potent than 70s ganj?

[Flameon]

if I went back in time and nicked a hippies sack would it really be exceptionally weaker than our standard chronic?

The 'establishment' view that there is now some form of super strength weed that is destroying the very fabric of our society is just a fabric-ation!

Yes, weed is generally stronger now than in the 70's, but that's thanks to experienced (and well informed) growers like: stinky, weedhound, opie and rhizome passing on the benefit of their wisdom to a new generation of consumers.

The average 'hippie' back in the 70's wouldn't necessarily have known that letting a male plant pollinate a female would weaken the potency of the grass, and as a consequence their 'sack' would have only contained weak grass and seeds!

Damn, those hippies lol.
