Key specifications

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.

Growing — indoor and outdoor

Indoor growing

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.

Outdoor growing

Two harvests per season possible: 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.
