You know, it's a difficult one to pin down! I have a chunk in front of me right now and the memory of what it was like grown indoors.
First of all, what it isn't: there is a distinct absence of sweet, skunky, or "kushy" elements in the aroma and flavor.
That isn't meant to downplay the fact that this is very smelly, sticky herb. There's just something to it that is unique, almost metallic or maybe more appropriately, a mineral-earth quality. There are elements of citrus in the background but there is a predominant herbal/medicinal/earth profile.
The flavor is sweeter, and I get citrus/mint notes along with a more "old school" spicy herbal flavor. I will note here that the outdoor sample smokes a little rougher than average herb despite the white ash it leaves behind, but is still pleasant and tasty.
Thank you green genes,
Great info!
