I suppose all the white strains as they coat with cristals.if you go for one try to pick the best genetics,I mean a good breeder(eg.serious seeds as they have very good genetics of WW and White Russian.genetics and good stretch is important as it means more buds and leafs covered with cristals) I also think it would be good to feed the plants with some sugars - I got something called CarboBlast (
CarboBlast a concentrated blended mixture of carbohydrates (2.5kg)) and it made the plant not only sweet but also "fluffier" with cristals.
all the best
