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.
Two cannabis plants in a growroom. A growroom (or grow room) or growth chamber is a room of any size where plants are grown under controlled conditions. The reasons for utilizing a growroom are countless. Some seek to avoid the criminal repercussions of growing illicit cultivars, while others simply have no alternative to indoor growing.
Most common annual vegetables have optimal germination temperatures between 75–90 F (24–32 C), though many species (e.g. radishes or spinach) can germinate at significantly lower temperatures, as low as 40 F (4 C), thus allowing them to be grown from seeds in cooler climates. Suboptimal temperatures lead to lower success rates and longer ...
Cannabis sativa is an annual herbaceous flowering plant. The species was first classified by Carl Linnaeus in 1753. [1] The specific epithet sativa means 'cultivated'.
Seed dormancy is defined as a seed failing to germinate under environmental conditions optimal for germination, normally when the environment is at a suitable temperature with proper soil moisture. This true dormancy or innate dormancy is therefore caused by conditions within the seed that prevent germination.

Know Germination Temperatures Salad greens do best in cooler weather so pay attention to the indoor temperature. Many salad green seeds germinate when the temperature is between 50-70°F.
[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]
