Transpiration & Wind

In my readings about transpiration i've learned a lot but only once came across the wind factor and it didn't mention anything except that wind speed affects transpiration.

I have a plant that is closest to a fan in the room.
towards the end of its light cycle 18/6 it wilts and
the plant tends to shrink its veins (?) causing the leaf matter to pop up a bit making the leaves look embossed or chiseled.

its the only 1 of 3.
you're gonna ask so;
400w hps@14" away from tops
plants LST'd
res temp 16-19C
D.O. 9.2 - 9.8ppm
plant tops 26C rh 40-55
ph5.8
EC.5

what is this?
im curious if the plant is wilting because it cant transpire fast enough because maybe the cool wind is closing the stomatas? and slowing transpiration?
in the AM this lady is full of pressure and reaching out everywhere. -and the fan stays on all night. in no way is the fan blowing straight on the plant too.
i've kept it so that the leaves only move a bit.

does anyone have any good reading on transpiration and wind speed?
on top of telling me why shes wilting? / stressing.

...hopefully this goes better than my DNF thread :S lol

FML!!!
moved to general growing...?
not even to plant problems?
im literally asking "what is this?" and looking for troubleshooting information!

awesome RUI. maybe the guys reading the DIYs or buying lights can help me out....
I have 72 posts in just over a month and this was my second question...
im already disappointed...

Your question seems more researched based and obviously you haven't found it. This is something I'm pretty sure most people won't even consider or ever even thought about. From what I've read more air would moving air around will cause it to be "dryer" around the leaves, thus causing it to transpire more. It wouldnt cause the stomatas to close.

You should upload some pictures if you can to show us what you mean by embossed and chiseled.

If you are worried about it try upping the humidity in the room and backing off on the the wind factor. Than you can judge for your self. At the end of the day research only goes so far sometimes you just gotta do a good old trial and error. Besides these plants are pretty resilient so i wouldn't worry too much.

Leaves can change their shape a little in response to excess transpiration. Caused by wind like you say. It's like a kind of defense mechanism to minimize moisture loss. That's why I move my pots around the grow room. If it is a problem, spray an anti desiccant.
Magic Green is one. Wilt Pruf is another.

humidifier added up wind. slight re-organization.
super stoked about the responses.
I was kinda thinking (maad 420 thoughts right) that if the wind was blowing coolness, it could contract cells causing the stomata to tighten and causing the plant friend to have a hard time transpiring.
im gonna kick my RH up like you say.
I tried to hook the fan up on a rheostat but it didnt slow. its a honeywell desk type fan. 8" but moves air well. its on 1 and still a bit strong (maybe).
I've got 3 thermometers in there so im pretty sure the radiant heat isn't too high.
they're drinking and eating pretty much level give or take 100ppm.
maybe 2L every 48hours. (3 lst'd SSchronic veggers).

thanks for the thoughts, something is defo better than nothing.
keywords are a slut sometimes. I may have been thinking too far into this.
coulda just googled "wilt". lol. but when im onto something i need to find the answer so i can close that caper!

i still wanna know more about wind speed

I just read earlier in a book that some species close stomata in heavy wind.
I'm gonna lower the breeze in my room andobserve for a week.

First day withthe breeze turned down andfacing away, just enough to flip theleaves aroundgently.
Instant rebound, leaves perked up, growth began again ((my young veg room became stunted)
And vertical growth was noticed.

I don't have any proof,
but I completely believe that Cannabis, especially being a thin leaved plant, closes stomata when leaves are violently shaken, such as a breeze.

Closing stomata will help retain moisture inhigh w/inds, but also disable or severelyreduce gas exchange (CO2 for O2)
