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. Whether you search for it as White Widow Auto, White Widow autoflower or White Widow automatic, it is the same strain. For the full story of the strain and all variants, see our White Widow strain guide.
The Auto White Widow effect is identical to the classic version — two-phase and balanced:
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 |
No light switch needed — a constant 18/6 throughout the whole cycle. Finished in 65 days from germination (LED: 58 days). Yield: 450 g/m² standard, up to 700–750 g/1.5 m² with a 720 W LED. Growth height 80–160 cm — LST recommended for more compact setups. Sow directly into the final pot size — autos are sensitive to root stress.
Two harvests per season possible in the northern hemisphere: first sowing April/May → harvest July/August; second sowing June/July → harvest September/October. A compact growth habit (from 70 cm outdoors) and discreet smell — ideal for balcony and urban projects. 70–200 g per plant. Because it finishes in about 65 days whatever the day length, Auto White Widow suits short seasons — the UK, northern and central Europe, Canada and the northern US — where a photoperiod plant might not ripen before autumn. In long seasons — southern Europe, California and the southern US — the two-harvest schedule above makes the most of the summer.
