Maybe I'll get my first 13-finger leaf. I've had 11 a few times, but I haven't seen a 13 yet. One day.
Atlantis nutrient = Atlantis-Indoor-Ultimate-Minerals-Vitamins.
Homebrew = Vitamins
Vitamin A (retinol, retinoic acid): The body converts provitamin A carotenoids (orange/yellow pigments like chlorophyll), like beta-carotene, into vitamin A (retinol).
B1 (thiamin):
B2 (riboflavin):
B3 (niacin):
B5 (pantothenic acid):
B6 (pyridoxine):
B7 (biotin):
B9 (folate):
B12 (cobalamin):
C (ascorbic acid)
For the 6 hours of the night, there is full UVB 24/7 exposure for shits and giggles, although none of the 280nm reaching plant is Photosynthetically Active Radiation, I have been meaning to test this out for a while, UVA I tried last grow was still drifting Into PAR at 365nm on the tail end keeping light above levels of the moonlight. 0.1ppfd This time I try 280nm.
*Not currently disrupting the plant's ability to detect the night cycle shift, with UVB left on at night, the plant is reacting to how I'd see it in complete darkness whereas the UVA last grow was clearly preventing plants from initiating the relaxed state I'd expect about 30 min before lights out, as if heliotropism was making them direct/dance towards each uva light individually making them look as if they were dancing in circles all night, figuring how close uva is to blue I'm not surprised. Cryptochromes are blue & ultraviolet-A photoreceptors. UVR8 is for UVB alone, UVR8 activates 10x more between 280nm-290nm, than 290nm-300nm.
Stomata Opening
As VPD increases, stomata get smaller.
CO2 uptake
As VPD increases and stomata get smaller, CO2 uptake gets reduced.
As VPD increases, the plant transpires (evaporates from leaves) faster due to the larger difference in vapor pressures between the leaf and the air.
As VPD increases, and transpiration increases, the roots pull in more nutrients. The plant is like one connected system of plumbing.
As VPD increases, there are more forces acting on the plant – from the leaves to the roots – and the plant experiences more stress.
Transpiration is the process by which plants release water into the atmosphere through their leaves. It's a passive process that cools plants and is a major part of the water cycle.
Plants absorb water and nutrients from the soil through their roots , the water is transported through the plant's tissues to the leaves water evaporates from the leaves through tiny pores called stomata. Transpiration removes heat from the air and cools the plant, transpiration returns water to the atmosphere, which is a major part of the water cycle. The water that enters the roots contains nutrients that are vital for plant growth.
Factors that affect transpiration
Temperature: Higher temperatures increase the rate of transpiration
Light intensity: Higher light intensity increases the rate of transpiration
Wind speed: Higher wind speeds increase the rate of transpiration
Humidity: Higher humidity decreases the rate of transpiration
Carbon dioxide levels: Higher carbon dioxide levels decrease the rate of transpiration
Evapotranspiration: The sum of transpiration and evaporation
Stomatal transpiration: One of the three main types of transpiration
Guttation is a process that occurs when plants take in too much water from the soil and can't evaporate it through their stomata. This causes water pressure to force sap out of the leaf's edges or tip, making it look like the leaf is wearing a tiara.
Perspiration is the process of releasing sweat from sweat glands in the skin. It's also known as sweating.
Plants "sweat" through a process called transpiration. Transpiration is the process by which water evaporates from plant leaves, cooling the plant and the surrounding.
Respiration is the process of metabolizing sugars to produce energy, while transpiration is the process of releasing water vapor. Both processes occur in plants and involve the exchange of gases with the environment.
Plants use respiration to create energy for growth, reproduction, and other life processes.
During respiration, plants use oxygen and stored sugars to produce carbon dioxide and water.
Plants respire through all parts of their body, including their roots, stems, and leaves.
Transpiration is the process of releasing water vapor through the stomata of leaves.
Transpiration helps dissipate the heat produced by plants through metabolic processes like photosynthesis and respiration.
Transpiration adds water to the atmosphere.
Stomata are small openings in the leaves of plants that allow for gas exchange and transpiration.
Guard cells control the opening and closing of stomata
