New Moon Over Guawi: A High Brix Journey

" When water pressure is high, the stomata open. So, if the plant has plenty of water, it automatically tends to keep its stomata open. If it's short of water, it automatically closes them. Yes, that slows down photosynthesis, but it also prevents the plant from wilting and dying due to dehydration.

So this is, to me, why VPD is so damn important haha! If we keep the stomata open and maintain that VPD needed to keep them open we can force them to drink more. Which should, in theory, grow bigger healthier plants. The goal, correct me if Im wrong, is to grow roots in veg and then use those roots in flower. What better way to use them than to continue to keep the plants stomata wide open like a turbocharger lol!

One thing, though, is that your thread that you quoted makes no mention of external factors like VPD having an effect on stomata.

The opening or closing of stomata occur in response to signals from the external environment.

Light = Stomata open (and maybe according to the MIX of light at sun-rise)

Dark = Stomata close

High CO2 inside leaf = stomata close

Low CO2 inside leaf = stomata open

Drought stress = stomata close

taken from the following thread

How the stomata works and how it can help us.

"Closure of stomata by drought is caused by abscisic acid, a plant hormone that is synthesized in response to drought. Abscisic acid overrides other signals and closes stomata when saving water is more important than photosynthesis.

Light causes stomates to open. The minimum light level for opening of stomates in most plants is 1/1000 to 1/30 of full sunlight, just enough to cause some net photosynthesis. Blue light (430-460nm) is nearly 10 times as effective as red light (630-680nm). The wavelengths that are effective in the red part of the spectrum are the same as those that are effective in photosynthesis ie is absorbed by chlorophyll. However, the blue light effect is quite independent of photosynthesis. Photosynthesis will change intercellular CO2 concentrations and may have its effect through number.

Potassium also plays a large role in the Guard Cells function in opening the stomata.

Blue-light wavelengths of daylight, detected by zeaxanthin (a carotenoid) activate proton pumps in the guard cell membranes, which proceed to extrude protons from the cytoplasm of the cell; this creates a "proton motive force" (an electrochemical gradient across the membrane) which opens voltage operated channels in the membrane, allowing positive K ions to flow passively into the cell, from the surrounding tissues. Chloride ions also enter the cell, with their movement coupled to the re-entry of some of the extruded protons (Cl/H symport) to act as a counter-ions to the potassium. Water passively follows these ions into the guard cells, and as their tugidity increases so the stomatal pore opens, in the morning. As the day progresses the osmotic role of potassium is supplanted by that of sucrose, which can be generated by several means, including starch hydrolysis and photosynthesis. At the end of the day (by which time the potassium accumulation has dissipated) it seems it is the fall in he concentration of sucrose that initiates the loss of water and reduced turgor pressure, which causes closure of the stomatal pore.

ABA also seems to trigger a loss of K ions from guard cells. Some workers suggest that in some species, ABA alters turgor pressure without changing solute potential or water potential.

Potassium is the "plant-preferred" ion for maintaining the water content and hence the turgor (rigidity) of each cell, a biophysical role. A large concentration of potassium in the cell sap (i.e. the liquid inside the cell) creates conditions that cause water to move into the cell (osmosis) through the porous cell wall (Box1).

Turgid cells maintain the leaf’s vigour so that photosynthesis proceeds efficiently.

The plant controls the opening /closing of the stomata by regulating the concentration of potassium in the guard cells. A large concentration of potassium ensures turgid cells and open stomata. When the potassium in the guard cells is lowered, they become limp and the stomata close. "

Dammit gazoo just answer the question I can't read that long ass article haha

True I should find some links supporting that as well, but as you just explained its all very related :)

Here is an article that suggest the STOMATA response to VPD can be disrupted by long term low VPD

Can prolonged exposure to low VPD disturb the ABA signalling in stomatal guard cells?

Wow... guess I missed the pics. My bad... looks like some delicious smoke! You’re patient, and you will be rewarded for that! Mmmm I can just imagine that first taste...

I hope the quality is better than the quantity :) really disappointed in the yield but its my fault for setting
the environment up for the SATIVA side of things.

Yup GDG ;)

Nice!!!!! After seeing your pics I need to step up my toy game.

Hell yea, I was at best buy yesterday and saw some starfox stuff... came close to buying.

I like the added color ;) and a little distraction is Fun. All my Toys are from the Dollar store, flea market, garage sales
or thrift stores. I never know what is stopping in next
 
GDP smoke report​

Decided to give the GDP a taste
Did a small thumb size bud early this morning on a fresh start,
it lasted approx 2 hrs.

SMELL / TASTE
Broken bud smell was Lemon/pine-sole & grape at times
taste was very very smooth like air with only a faint taste of GRAPE
on inhale, on exhale its a bit different and more of a fruity taste, cant put my finger on it yet

First thing I noticed was I could not keep a train of thought, seem to drift from thought to thought
Then noticed a tunnel vision kinda thing Everything became very focused and felt like I had blinders
on ? Like a loss of Peripheral vision BUT NOT really ? just seemed to be very focused on things

My next realization was that I had been very chatty with strangers :) and found humor in just
about everything

So far Very good hope the smell and taste get stronger OH took out the Bovidas this
time but they did cure for about a week with them so maybe that's part of it as well

Awesome looking buds and great smoke report!

I was wondering if you would elaborate a little on your environmental setting being more sativa friendly. What do you think would have been more optimum?

1st great review 2nd I thought you lived alone, so were there really strangers or were you talking to yourself :laugh:

I suspect the 11/13 and the Far-Red addition speed things up to fast. There was Just not enough time for
the Shorter Indica Flower time. OH the Heavy UV I included could also be the reason for
the immediate Fan leaf loss at Mid flower

EDIT : I should include Its was more of a EQUATORIAL SATIVA environment
