Description

Very pleasant long lasting berry aroma

A mostly indica strain, Blueberry is a classic that dates back to the late 1970s and under ideal conditions is a very large producer. A dense and stout plant with red, purple and blue hues, Blueberry as a finished product has a very fruity aroma and, as you'd expect, a taste of blueberry. It produces a prominent and nicely euphoric effect of the highest quality and is very long lasting. Blueberry also has a long shelf life, ideal for collectors who wish to preserve for future use.

You can find the iconic real blueberry flavor and smell with seedsman however you will need to grow I'd say 15 to 20 seeds to find that perfect pheno. I've been growing for over 8 years and I got a seedsman blueberry freebie with a previous purchase when I grew those three seeds one of them was really really flavorful and had that iconic blueberry smell unfortunately since I didn't clone it I tried to get another batch and it took about 15 seeds till I got about two or three perfect blueberry flavored strains
