possible...yes
but yet AGAIN all i see is assumptions.

If you can't prove the seedbank wrong then they are correct.

Purple Haze is as real as any other strain. I have smoked it. I have seen it.
It was crap like most other purple strains. If i wanted seeds for a purple variety i would certainly not choose PurpleHaze, neither would anyone else ive ever talked to. So why would the name "purpleHaze" expect to make more money? If your knowledgable enough to be growing ur own weed you would never even consider buying PurpleHaze cos its shite! Its likely its the banks worst selling breed!! So why would they lie? What do they have to gain?
