Big Bertha

Cannabis Strain by Reefermans Seeds

Introduction
Big Bertha from Reefermans Seeds carries the name of history's most famous artillery piece—the massive German howitzer deployed in the First World War—applied here to a cannabis variety bred by one of British Columbia's most celebrated genetics operations. The name promises scale, and at approximately 70 days of flowering in indica/sativa balanced format, Big Bertha delivers on the ambition.

Lineage
Reefermans Seeds was founded by the late Greg "Reeferman" Watson in British Columbia, and represents one of the most important archives of Pacific Northwest and global cannabis genetics assembled in the early 21st century. Watson was a plant geneticist by training who applied genuine scientific methodology to cannabis breeding—collecting, preserving, and developing genetics from around the world with a rigor unusual in the underground breeding community. Reefermans Seeds earned multiple international genetics awards and became particularly known for their rare landrace and heirloom genetics. Big Bertha at 70 days as an indica/sativa hybrid suggests a more complex genetic architecture—possibly involving sativa-dominant landrace genetics crossed with Pacific Northwest indica to produce a variety with both the scale the name implies and the balanced hybrid character. The 70-day flowering window is on the longer end of hybrid development, suggesting sativa influence contributing to the finish time.

Terpenes
The terpene profile in Reefermans' BC-developed hybrid likely features a complex, multi-layered expression: earthy myrcene and piney alpha-pinene from Pacific Northwest heritage, caryophyllene spice, and the distinctive resinous quality characteristic of BC outdoor genetics. The scale implied by "Big Bertha" suggests a terpene expression as generous in volume as in complexity.

Growth
Growth at 70 days with balanced indica/sativa character produces taller plants with substantial branching—moderate growing difficulty, rewarding for experienced cultivators.

Effects
Reported effects combine mental elevation with physical relaxation across the extended 70-day development window.

Documentation
Reported applications include mood support, relaxation, and creative engagement.
