This is funny.
Hydro is no better than soil grown , it isn't the method that delivers the goods it's the experience of the grower.
From the first post I have the impression you only get two strains where you live , I have never heard of sess but as has already been pointed out there is no such "strain" as DRO ! it is a way to grow not a kind of cannabis.

Cannabis has so many strains now that the end result can be varied in colour but potency is not in any way linked to colour.
