Its true, if you want pure blueberry flavor, go with buedigiberry, you have better chance there.
However, the Blueberry flavored plant I found in bluedigi line was terrible smoke. It was extremely tiring, I smoked it 2-3x and realized its pure night time meds. The other phenotypes were more NLD looking, but I did not find the smoke interesting neither. It was not nearly as euphoric as original blueberry. Not saying the magic is not there! But I didnt find it. To be fair, while the true blueberry flavor may be lacking, Djs Blueberry has much more refined high, it was consistent for most phenotypes, so depends what you are after. The Blueberry sativa pheno I found is a favorite smoke for a lot of people that tried it, the F2 plant I grew last year was even better than the mother.
Btw, I grew Newberry and got 3 females from 6 seeds. One of them smelled like blueberry mixed with lavender and bit of skunk and it was a loud smell. The high was great, strong, pleasant, does not drain you from energy, no comedown. Great stuff.
