Knowing the strain names is a hint of respect for the people who grow and breed weed. If you know the strain name, chances are you can look up the genetics online and you'll know what kind of effect it will have on you. Like sativa, indica, or a mixture of both.

Anyway I pay 270/ounce for named strains like purple kush, jack herer and sour diesel and hashplant. Smoke my weed and you'll never pay for anything else
