I have the original cheese clone, had it since before anyone started talking about exodus cheese, brightside, etc. The clone was imported from the UK in early 2000-2002.
The pics I have seen from growers here tell me that the brightside is the same clone, but nobody has been able to provide a DNA sample to confirm or disprove this hypothesis.
The flowers look identical, cheese has some traits that are not very common on their own, let alone all together like you see with her so if you know what to look for, you can spot the traits even across the internet.
I have flowers going into the lab in the next 2 weeks to get a chemical fingerprint. If any of you brits want to share DNA, pass it along and we'll get it run through a sequencer and see if we can get a fingerprint that matches what we know as cheese, or we can put some evidence more than just rumor and talk to this cheesy tale.
Im up for sending samples to this guy. Ive pm'd him. Even if its a match with his cheese, it may not be Brightside but one useful thing will be to confirm if Dogons and windows cut are the same. If OJD can send some of his Brightside, we can see if Dogons, Windows or Chimeras match.
