Ok, chem 91 x (Pakistani kush x lemon Thai) is the best explanation of og genetics to date IMHO. It makes sense and I've heard this from a few sources. I know og is sativa Dom because high thc is sativa characteristic. Indica have higher cbn and cbd. Look up a medical testing site. (Budgenius.com) og, sour d, hazes always have the highest thc. All 3 sativas. My theory on why og knocks people out is that the thc rush is so fast and speedy, the crash about 30 mins in puts you on a sick body lock downer, like it wears you out kinda rush high. But with og you always get the head high & slapped in the face baked with mood enhancement. It's one of the few sativa kushes. Look at the flower time, stretch, lankiness. To call it a pure indica is just ignorant, it shows me youve never grown the strain.(no offense).
