hello, was wondering something about the og raskal strains.

I see there is white urkle and white fire urkle.. is one strain stronger then the other? is there any major differnce between them such as a better couch lock or anything?

also im looking at

white urkle
white alien urkle
Fire Alien Romulan
white Fire Alien (or fire alien white)

was wondering if anybody knew what they should reach for thc% on avarage and what , i tried googeling but never really found any thc% just more pics

and which one would be the strongest best for medical patients.
