Well if I had to guess, it looks pretty straight sativa, so something with a strong durban poison influence. Yes I know theres a lot of Durban in sativa strains but that's what I would guess. Maybe blue dream or some hybrid crossed with Durban.I FIMed it and it fucking hated it. Lol maybe the pheno?
Hint is, it looks like a sativa!! Year+ old seed my dad got with an order. No clue.
