Type and naming

Reading this profile
Sensi Seeds attribution applies to its Jack Herer line; other seed-bank listings are not automatically the original. The references describe particular accounts or breeder versions; they do not authenticate a retailer's stock.
What remains uncertain
- Exact parental selections and relationships between commercial versions are not established by this review.
- No traceable batch laboratory report was added in this review. Chemical values and effects elsewhere in the catalog remain source descriptions, not findings established by this article.
