Heartbreaker
Heartbreaker is a modern automatic cannabis variety developed through the crossing of White Stomper V3 and Wizard’s Apprentice. This strain is cultivated for its ease of growth, reaching maturity in an 80-day flowering cycle that allows for successful cultivation in both indoor and outdoor environments, though growers should anticipate a low yield. Following its emergence, Heartbreaker has been utilized as a foundational genetic component in the development of numerous subsequent projects.
The chemical profile of Heartbreaker is characterized by a complex terpene hierarchy led by myrcene, pinene, and caryophyllene, followed by beta-pinene, limonene, nerolidol, linalool, humulene, ocimene, guaiol, camphene, bisabolol, and caryophyllene-oxide. This diverse composition informs the strain’s distinct sensory profile, balancing earthy, pine-forward notes with subsequent hints of spice and citrus. The interplay between these specific terpenes defines the aromatic nuance experienced during consumption.
As a THC-dominant cultivar, Heartbreaker is categorized by effects that are primarily relaxed, happy, and uplifted. These characteristics make the strain a functional choice for those seeking relief from stress and physical pain, while also serving as a nocturnal aid to assist with sleep. The genetic legacy of this variety is evidenced by its inclusion in the lineage of notable offspring such as Cake Breaker, East Coast Sweet Heart, Heart of Gas, Heart Shot, HeartBreaker F2, Hearty Truffle, King Of Hearts, Secret Project, and The One That Got Away.

Research notes below describe isolated terpene mechanisms and early findings. They do not guarantee effects from this strain and are not medical advice.
Russo 2011: naloxone-sensitive analgesia, potentiates barbiturate sleep; dominant sedating terpenoid; blocks hepatic carcinogenesis by aflatoxin.
Russo 2011: acetylcholinesterase inhibitor (IC50 0.44 mM) counteracting THC-induced short-term memory deficits; most widely encountered terpenoid in nature; anti-inflammatory via PGE-1.

Russo 2011: only terpene that is a selective full CB2 agonist (100 nM); Gertsch et al. 2008: acts as dietary cannabinoid; unique anti-inflammatory and gastric cytoprotective properties.
Effects
Reported effects — derived from terpene chemistry and cannabinoid profile.
relaxed
eveningPrimary endpoint of myrcene+linalool sedating combinations; GABA modulation is the dominant mechanistic driver.
happy
anytimeuplifted
morningLimonene anxiolytic/antidepressant via serotonin elevation in prefrontal cortex (Russo 2011); mood improvement without full euphoria; key for balanced-1-1 profiles.
Genetic Profile
Autoflower
Photoperiod-independent. Flowers based on age, not light cycle. Compact and fast.
THC-Dominant
High THC, trace CBD. Psychoactive. Full CB1 agonism — euphoria, appetite, analgesia.
