No, it's not listed by ascending potency. It's listed in the order I wrote them up. If I were to try and list it by potency, it would be more like this:High Grade--------------Rhino HazeSour JackHawaiian PunchPurple KushMedium Grade------------------Dutch TreatG-13CheeseKeep in mind I have smoked a lot of the above strains, so my tolerance and the effects I get will be different than others. I find that the stuff I smoke regularly seems to lose it's potency after a while and the stuff I don't touch that often really hits me. The above list is how those strains effect me, and I smoke upwards of an ounce per week.MJMuse
