Birthday Cake X Birthday Cake

Cannabis Strain by TH Seeds

Introduction
When a breeder crosses a strain with itself, the typical goal is stabilisation — narrowing genetic variance and fixing desirable traits. TH Seeds' Birthday Cake X Birthday Cake does exactly that: takes the Birthday Cake genetics and drives them toward greater uniformity. The result is a mostly sativa-classified variety with a 58-day flowering period, which is unusually quick for a sativa-leaning hybrid.

Lineage
**Genetic Lineage** Birthday Cake X Birthday Cake is a mostly sativa hybrid from TH Seeds (TH Seeds™), available as regular seeds with a flowering period of approximately 58 days. TH Seeds is an Amsterdam-based company with roots going back to the 1990s; they have produced classic varieties including MK Ultra, S.A.G.E., and various modern hybrids. Birthday Cake itself is a well-established modern American hybrid — typically understood as a cross between Girl Scout Cookies and Cherry Pie (or Wedding Cake and Cherry Pie, depending on the source). The self-cross by TH Seeds creates an F2 or inbreeding step, which typically increases genetic uniformity while potentially fixing specific phenotype traits. The mostly sativa classification despite the indica-heavy parent genetics is noteworthy.

Terpenes
**Terpene Profile** Birthday Cake is associated with sweet, vanilla, and doughy aromatic profiles characteristic of Cookie-family genetics: caryophyllene, limonene, and myrcene in a dessert-confectionery arrangement. The self-cross should largely preserve this terpene signature while selecting for consistency. The mostly sativa classification may introduce some brighter, more herbal top notes if the cross has selected for sativa-leaning phenotypes.

Growth
**Growth Characteristics** At 58 days, this variety is fast for a sativa-classified plant. TH Seeds' Amsterdam breeding background tends toward manageable, well-adapted genetics. Regular seeds. The birthday cake parent genetics typically produce moderately compact plants with abundant lateral branching and dense, resinous flowers.

Effects
**Reported Effects & Experience** Birthday Cake genetics are associated with an uplifting, mood-enhancing onset that transitions to relaxation — a balanced experience consistent with the Cookies and Cherry Pie parentage. The sativa classification suggests a more cerebral emphasis in this expression.

Documentation
**Medical Applications** No specific therapeutic data for this cross. Cookie-family genetics are widely reported for stress and mood support.
