As a licensed farmer I now have access to multiple strains and I almost always make a salad in my joints, bowls and vaporizers to get the best effects. Sometimes I will go with just one to get a particular effect or taste from a specific strain, but that would be with my VIP strains
I think that the only time I will not mix really is right after harvest, when not everything is ready and I'm stuck with just one. But I'm usually back at mixing again in no time! lol
