The optimal day temperature range for cannabis is 24 to 30 °C (75 to 86 °F). [12] Temperatures above 31 °C (88 °F) and below 15.5 °C (60 °F) seem to decrease THC potency and slow growth. At 13 °C (55 °F) the plant undergoes a mild shock, though some strains withstand frost temporarily. [13] [14] [15]
[3] [4] Cannabidiol (CBD) is another major constituent of some cannabis plants. [5] Conversion of CBD to THC can occur when CBD is heated to temperatures between 250–300 °C (480 to 570°F), potentially leading to its partial transformation into THC. [6] At least 113 distinct cannabinoids have been isolated from cannabis. [7]
The autoignition temperature or self-ignition temperature, often called spontaneous ignition temperature or minimum ignition temperature (or shortly ignition temperature) and formerly also known as kindling point, of a substance is the lowest temperature at which it spontaneously ignites in a normal atmosphere without an external source of ignition, such as a flame or spark.

Cannabis (/ ˈ k æ n ə b ɪ s /) [2] is a genus of flowering plants in the family Cannabaceae that is widely accepted as being indigenous to and originating from the continent of Asia. [3] [4] [5] However, the number of species is disputed, with as many as three species being recognized: Cannabis sativa, C. indica, and C. ruderalis.
CBD heated to 175, [13] or 250–300 °C may partially be converted into THC. [14] Even at room temperature, trace amounts of THC can be formed as a contaminant in CBD stored for long periods in the presence of moisture and carbon dioxide in the air, with storage under inert gas required to maintain analytically pure CBD.

[19] [20] Cannabis x intersita Sojak, a strain identified in 1960, is a cross between C. sativa and C. ruderalis. [3] Attempts to produce a Cannabis strain with a shorter growing season are another application of cultivating C. ruderalis. [8] C. ruderalis when crossed with sativa and indica strains will carry the recessive autoflowering trait ...
