Credited for something of a mini-revolution in genetic engineering (kind of!), Chem Dog turned up in the form of 13 seeds that emerged during an early 90s Grateful Dead tour when the band hit Colorado. The simple fact of the matter is that no strain has given birth to more Cannabis Cup winners so far this century than Chem Dog. From Stardawg to Sour Diesel to OG Kush and her whole bloodline, we have a lot to thank Chem Dog for.
