Genetics and origin
Auto White Widow is based on the original White Widow — the 1995 Cannabis Cup winner and one of the most famous 50/50 hybrids in the world. The autoflowering trait was introduced in autoflower format without altering the signature White Widow profile: same effect, same aroma, no light schedule needed. For the full story and all variants, see our White Widow guide.
Auto White Widow effects
The Auto White Widow effect is identical to the classic version — two-phase and balanced:
- Euphoric, clear onset — the mind wakes up, a creative and sociable mood
- Physical relaxation — without heavy couch-lock at moderate doses
- Stress relief — ideal for the end of the day
- Strongly relaxing — sedating at higher doses, supports sleep
Aroma and terpene profile
The characteristic White Widow aroma profile is fully preserved in the autoflowering version: earthy-spicy, woody, with a resinous sweetness. Its legendary trichome production makes it especially attractive for extraction.
| Terpene | Typical impressions | Contribution to the profile |
|---|
| Myrcene | Earthy, musky, sweet | The base of the relaxing body effect |
| Caryophyllene | Spicy, peppery, warm | The characteristic spice, complements the earthy profile |
| Pinene | Fresh, pine-like, clear | A fresh finish, supports mental clarity |
