The Purple strain is from a friend that grows,I don't know what he crossed it with,but they came from seed,it smells just like sour grapes.It's in the 5th week of flowering.The other strain I got from him also.1 of the phenos turns purple also in the last 2 weeks of flowering but doesnt smell as good,but it's super frosty,it smells skunky and spicy.
