Green Crack is a Skunk x Afghani crossed by a fellow called Cecil , also known as Cecil Cush. Cept if you are in B.C. Canada, here it's a Reeferman cross of Hashplant and Purple Kush. Peace GS
in addition to the info provided, it flowers faster then a ma-fucker it can be cropped as early as 43 days but is just about perfect @55 smell and taste are difficult to descibe but very unique and great! enjoy!
