Chemdawg Weed Strain. has developed quite a name for itself over the years. Between its mysterious origin, ambiguous genetics, and the plethora of successful crosses the strain has produced, chemdogs has practically secured itself a permanent place in the cannabis hall of fame. The original source of powerhouse strains like Sour Diesel and OG Kush, ChemDawg is known for its distinct, diesel-like aroma. Pungent and sharp, you’ll be able to smell this strain from a mile away. Chemdawg (aka Chem Dog) is the rumored combination of OG Kush and Sour Diesel. Which instantly makes it a crowd favorite among cannabis connoisseurs. This full-bodied hybrid is one of my personal favorites.
