  2. Cannabis cultivation - Wikipedia

    en.wikipedia.org/wiki/Cannabis_cultivation

    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]

    A 2022 Outside article on heat stroke cites the highest known body temperature that a human was able to survive: “The highest body temperature measured was only 17 degrees above normal. Willie ...

  4. Chemical defenses in Cannabis - Wikipedia

    en.wikipedia.org/wiki/Chemical_defenses_in_Cannabis

    These results support the mechanism in which cannabis elicitors such as salicylic acid and GABA triggers a signal cascade for increased expression of defense genes in response to stress. One line of defense is the release of volatile organic compounds (VOCs) into the air to defend against herbivores by warning neighboring plants. [20]

  5. Extreme environment - Wikipedia

    en.wikipedia.org/wiki/Extreme_environment

    An extreme environment is a habitat that is considered very hard to survive in due to its considerably extreme conditions such as temperature, accessibility to different energy sources or under high pressure. For an area to be considered an extreme environment, it must contain certain conditions and aspects that are considered very hard for ...

    en.wikipedia.org/wiki/Cryobiology

    The Society for Low Temperature Biology was founded in 1964 and became a registered charity in 2003 [23] with the purpose of promoting research into the effects of low temperatures on all types of organisms and their constituent cells, tissues, and organs. As of 2006, the society had around 130 (mostly British and European) members and holds at ...

  7. Planetary habitability - Wikipedia

    en.wikipedia.org/wiki/Planetary_habitability

    [72] Extremophiles are Earth organisms that live in niche environments under severe conditions generally considered inimical to life. Usually (although not always) unicellular, extremophiles include acutely alkaliphilic and acidophilic organisms and others that can survive water temperatures above 100 °C in hydrothermal vents.

  8. Cold hardening - Wikipedia

    en.wikipedia.org/wiki/Cold_hardening

    Non-acclimatized individuals can survive −5 °C, while an acclimatized individual in the same species can survive −30 °C. Plants that originated in the tropics, like tomato or maize, don't go through cold hardening and are unable to survive freezing temperatures. [3]

  9. Weed - Wikipedia

    en.wikipedia.org/wiki/Weed

    In St. Louis between the years of 1905-1910, weeds became viewed as a major public health hazard, believed to cause typhoid and malaria, and legal precedents were set in order to control weeds that would help facilitate the adoption of weed control laws throughout the country.
