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]
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.
Cannabis plants produce a unique family of terpeno-phenolic compounds called cannabinoids, some of which produce the "high" which may be experienced from consuming marijuana. There are 483 identifiable chemical constituents known to exist in the cannabis plant, [ 53 ] and at least 85 different cannabinoids have been isolated from the plant. [ 54 ]

Cannabaceae is a small family of flowering plants, known as the hemp family.As now circumscribed, the family includes about 170 species grouped in about 11 genera, including Cannabis (hemp), Humulus and Celtis (hackberries).
The chilling requirement of a fruit is the minimum period of cold weather after which a fruit-bearing tree will blossom productively. It is often expressed in chill hours, which can be calculated in different ways, all of which essentially involve adding up the total amount of time in a winter spent at certain temperatures.
The flowers of Cannabis sativa plants are most often either male or female, but, only plants displaying female pistils can be or turn hermaphrodite. Males can never become hermaphrodites. [ 3 ] It is a short-day flowering plant, with staminate (male) plants usually taller and less robust than pistillate (female or male) plants.
In controlled environment studies, the optimum average daily temperature for leaf growth for E. novogranatense var. novogranatense was found to be around 27 °C (81 °F), whereas leaf growth was generally higher at photosynthetic photon flux densities (PPFD) of 250 or 400 micromol per meter square per second than at 155 micromol per meter ...
