Cannabis plants, like many others, biochemically synthesize terpenes with intense aromas as a method of chemical defense in attempts to repel predators, and invite pollinators. Because terpenes and terpenoids are biologically active molecules, it is possible variations in terpenes may elicit different biological and psychoactive responses in ...
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 ]
Watering frequency and amount is determined by many factors, including temperature and light, the age, size and stage of growth [22] of the plant and the medium's ability to retain water. A conspicuous sign of water problems is the wilting of leaves. [23] Giving too much water can kill cannabis plants if the growing medium gets over-saturated.
Woody plants survive freezing temperatures by suppressing the formation of ice in living cells or by allowing water to freeze in plant parts that are not affected by ice formation. The common mechanism for woody plants to survive down to –40 °C (–40 °F) is supercooling. Woody plants that survive lower temperatures are dehydrating their ...
At low temperatures (frequently at night), plants using CAM open their stomata, CO 2 molecules diffuse into the spongy mesophyll's intracellular spaces and then into the cytoplasm. Here, they can meet phosphoenolpyruvate (PEP), which is a phosphorylated triose.
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 ...
At temperatures near 0 K (−273.15 °C; −459.67 °F), nearly all molecular motion ceases and ΔS = 0 for any adiabatic process, where S is the entropy.In such a circumstance, pure substances can (ideally) form perfect crystals with no structural imperfections as T → 0.
Air plants can be misted heavily, but it’s not always a foolproof method because it will need to be done daily until water runs off. Di Lallo prefers to dunk or soak the plants instead.
