Fire 99
Fire 99 is a modern hybrid cannabis strain derived from a lineage of Cinderellas. As a contemporary cultivar, it is cultivated with a flowering time of 60 days. This strain is suitable for both indoor and outdoor environments, offering growers a high yield, though it maintains a moderate difficulty level for those managing its growth cycle.
The chemical expression of Fire 99 is defined by a terpene profile led by myrcene, followed by caryophyllene and limonene as secondary and tertiary components. These dominant compounds contribute to the specific sensory experience of the flower, which is defined by the interaction between its heavy myrcene content and the structural sharpness provided by its subsequent aromatic constituents.
As a THC-dominant hybrid, Fire 99 is characterized by effects that leave users feeling relaxed, happy, and uplifted. These qualities make the strain a functional choice for those seeking relief from stress and pain, as well as assistance with sleep. The genetic legacy of this cultivar is documented through its notable offspring, including the strain Kushty.

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.
Russo 2011: increases serotonin in prefrontal cortex + dopamine in hippocampus via 5-HT1A; Johns Hopkins 2024: significantly reduced anxiety vs THC alone.
