good comments and questions !
firstly, a good quality auto from a good breeder has a good potency level. I can't (I really can't) tell the difference between any of our auto's and a traditional variety in a blind vape test. So one really important comment that I would make is to ignore any supposed link between ruderalis content and final potency. I can understand why people might make that link, but there is more to it that that.
I can't make any comments on auto's from other breeders. But in terms of the Dutch Passion range they are all bred to the same high standards and result in similarly top quality pot. That is the reason that we have eg PolarLights #3, we have upgraded the breeding process and genetics so that all our auto's meet the same high standards as those of our 'headline' auto's (Think Different, AutoMazar...). Once we know how to improve the quality level of an auto, even if it is just a small improvement, we make the improvement and the name will reflect that (PolarLights #2 ---> PolarLights #3, for example).
StarRyder is sativa dominant but not exclusively so, but as with all auto's, you get a genetic spread around the 'average'. So StarRyder, for example, will occasionally throw out a Pineapple scented pheno which has a stronger sativa-leaning to it, and this pheno may take another 7-10 days beyond the average and with thin sativa leaves. Likewise, you will see some shorter, squatter pheno's that have more of an indica appearance despite the fact that the variety is, on average, a sativa-dominant one.
I hope that helps !
