    • General impressions

      The grow went awesome. Of coarse I would of likes a way bigger yield. But the quality is definitely there. So for a true beginner granddaddy banner is recommended. It's very easy to work with. Plants bounced back from topping,trimming and lsting. Very resilient strain. I had 0% disease.
