Can some one please tell me the genetic make up on this strain. I was also told that GDP, Grape Ape and Purple Urkel were the exact same plant. Any truth to this ? I read on here where Purple Kush was a cross of Hindu Kush and Purple Afgani, but couldn't find anything here on what went into making a GDP plant, thanks to all.

The true genetics to GDP are unknown to the cannabis community. It is very closly related to Purple Kush, grown side by side they are almost identical. It is quite different from Grape Ape, and slighly different from the Urkle.
