Medical uses: Pain management, anxiety, insomnia, etc. Which strain is better for what ailment? Maybe knight of Erin for physical pain, Sugar Star for stress or depression.
First, I should outline the basic genetic backgrounds. The Knight of Erin V106 is an Indica-dominant hybrid, bred by a specific seed bank, maybe Irish Chronic and an unknown Indica. Sugar Star, on the other hand, is a cross between Strawberry Cough (Sativa) and Blueberry (Indica). So the genetic makeup is different, which would affect their effects.
User experiences from reviews or forums. Do people report consistent effects? Any notable differences in how each makes them feel?
Terpenes: Sugar Star has Limonene and Myrcene from Strawberry Cough and Linalool from Blueberry. Knight of Erin might have Myrcene, Caryophyllene, maybe some Linalool too.
