That's been my experience when I've been down in the Winter. Everyone has a name for their product, but it's usually all very similar. However, the one time I came in March there was definitely some very different strains around. And the purple haze was very purple. I'm not really worried about the potency since the strength of it in Jamaica is not like the hydro stuff back home. Moreso just variety in taste, aroma, smoke, etc.
