This strain was created by crossing Purple Thai with Afghani Indica. The sativa/indica ratio of this strain is found to be 60:40. The aroma produced by this strain will be sweet and sour like that is being produced from a lemon. This would taste light as well as lemony without any souring and the flavor would be more or less like a lemon drop. (Allbud)
