Three-way hybrid strain that is resistant, adaptable and very high-yielding. Its high level of THC production provides a strong, cerebral effect.

California Octane is a high-powered, slightly indica-leaning, feminised hybrid strain that was bred as a three-way cross of Dream Queen, I-369 and Papaya. California Octane is an almost perfect cannabis variety thanks to its hardiness, resilience and adaptability to a wide range of climate conditions. It boasts extremely high yields both indoors and outdoors with high resin production and very high THC, Outdoors, in California, total cannabinoid levels of 36% have been recorded.

When cultivated indoors the flowering time is approximately 60 days, while outdoors in northern latitudes growers can expect to harbvest in the first half of October. Crops of stacked and glistening colas have been described as 'huge' - encouragement enough to get growing! California Octane is a strain that is very commercially interesting.

The scent frojm this strain is overwhelmingly fuel-centric. THC content is up around 26% and this provdies an efffect that is potent and cerebral in nature.
