Answers to Common Questions About Growing Blue Runtz Cannabis Seeds
One seed took an extra day to crack but ended up being the strongest plant. Colors started coming through late in flower, some deep blues and purples under cooler nights.
I grow in a small tent and this one stayed manageable with a bit of LST. After cure the jars had a sweet candy smell with a slight berry twist.
First time running Blue Runtz and they were pretty vigorous from the start. Nice branching structure, easy to train, and the buds started stacking thick by week five.
