Blueberry Strain Review

Only 1/3 of the seeds actually sprouted

1.0 rating
13 May 2020

Only 1/3 of the seeds actually sprouted, in an actual greenhouse. The ones that have sprouted are less than half the size of the other strains and seeds we started at the same time. I was really looking forward to this strain but I’m afraid they won’t catch up at this point.

Just like a fine wine the longer it cures the better the berry!!


Great weed to enjoy late at night, or on those lazy days

Not many can top the euphoric relaxation that Blueberry gives you. A truly strong Indica with the power makes you feel sleepy even while you’re dreaming. It’s by far one of the most popular strains of all time.
The flavors are that of its name, very fruity. It’s a great weed to enjoy late at night, or on those lazy days. Also, if you have trouble sleeping, Blueberry is a great sedative.

I planted 2 seeds from a purchased 1/4 of Skywalker OG
Right from the start it was obvious there was a difference in the way each plant was leaning.
In the end one plant was predominantly blueberry where as the second was closer to its Mazar side.
Yield was not remarkable but the flavor / terp profile of the Blueberry was very pronounced.
Harvest was late September and could have been extended maybe 2 more weeks but weather in Michigan is too unpredictable to take a chance on October frost.
