Genetic Profile & Heritage
White Widow represents a distinctive hybrid expression developed through the crossing of two geographically and genetically distinct landrace cultivars:
| Parent Strain | Origin | Genetic Contribution | Characteristics |
|---|---|---|---|
| Brazilian Sativa | South America | Sativa lineage | Uplifting effects, cerebral qualities, energetic profile |
| South Indian Indica | Southern India | Indica lineage | Relaxing properties, resinous bud production, structural stability |
Lineage Dispute & Historical Context:
There exist conflicting claims regarding White Widow’s true origin. Ingemar (De Sjamaan), a pioneer in outdoor cannabis cultivation and early medicinal cannabis activist, has stated the strain was bred from seeds collected from friends and cultivated over years of experimentation. Scott Blakely (Shantibaba), renowned cannabis geneticist who travelled extensively through Asia and South America collecting seeds before settling in Amsterdam, attests he created White Widow by crossing a Brazilian sativa male with an Indian Indica mother . Dutch breeder Green House Seeds is widely credited with popularising the strain commercially .
Regardless of origination disputes, White Widow is unequivocally established as the mother of the esteemed “White” family of cannabis strains, including White Russian, White Rhino, Great White Shark, White Domina, and White Amnesia .
Morphological Characteristics
| Feature | Description |
|---|---|
| Bud Structure | Dense, conical, light green buds; some phenotypes produce fluffy, conical flowers |
| Pistils | Vibrant orange/gold hairs woven throughout bud structure |
| Trichomes | Exceptionally thick coating of sticky white crystal trichomes; strain named for this characteristic “frosty” appearance |
| Plant Height | Compact to medium; typically 100-150cm; rarely exceeds 3 feet outdoors |
| Growth Pattern | Bushy, dense, stacked leafy branches requiring training for light penetration |
The cultivar’s name derives directly from its most distinctive feature: buds appear almost white or silvery under their extraordinarily dense trichome coating, with the resinous crystals contributing to both its visual appeal and sticky texture .
Cannabinoid Profile
Laboratory analysis of White Widow flower demonstrates batch-dependent variability. Compiled ranges from accredited testing sources indicate:
| Component | Typical Range | Notes |
|---|---|---|
| THC | 18-25% | Batch-dependent; specific quantification per Certificate of Analysis |
| CBD | 0.1-0.2% | Low; quantified per batch |
| THC-A | Quantified per batch | Full panel on Certificate of Analysis |
| Minor Cannabinoids | CBG (~1%), CBN, CBC | Present in trace quantities; batch variable |
*Note: Specific potency data is provided exclusively via batch-specific Certificates of Analysis from ISO/IEC 17025 accredited laboratories. Ontario Cannabis Store lists specific lots at 22-28% THC . No specific potency claims are made without corresponding batch documentation.*
Terpene Profile
White Widow exhibits a complex terpene architecture with significant variability reported across different phenotypes and breeders:
| Terpene | Aroma Profile | Presence |
