Found few people on here and few others on another forum that all agreed it's higher than 13. Imo u can take swag bean and make killer from it if you treat it with love. I tried my buddy's back in December which led me to ordering some initially, I felt it to be above 13 has great energy with it and I was chatting it up after. So a motivated smoke, that has a very relaxing feel in ur limbs, I would say a good bowl lasts 2-5 hour high but relaxing feel for 6hrs. This depends on ur tolerance of course. I think u would be very pleased with it. I think I'm looking at minimum of 150-160g from mine, that is from my knowledge of growing and how much more she has to swell and go. Two weeks of good swell still then be flushing with water for two weeks.
