If you knew what VPD was you would have been able to work that out yourself. Also humidity is moot as you can't get the correct VPD without the correct RDH. Did you actually know what Vpd was?

when I see this pic I think I would've defoliated quite some of these lowhanging top fanleaves right away perhaps 2 weeks before... that would have allowed the light getting deeper into the plant, doubt there would be a loss of photosynthesis - it would still be dense, because there a number of colas here that will all absorb 100% of whatever light you throw at them.
but it's ok if it's working for you, and it'S looking impressive, I wonder how the smell in there was 
I just like how you fire off 20 replies a minute to yourself, but this one took like 10 minutes to get out of ya... a little google-fu eh?If you knew what VPD was you would have been able to work that out yourself.

But I can see why you as a mass producer cannot utilize LST or other techniques when there's still mess with accessability to the cola's. There's also so many plants....
Huh what's that got to do with whether you knew what vpd meant?
no he's not asking you about this. It's because of that there're several starting points when mold can grow increasingly (62%) so he's perhaps theorizing you've got something very low, like 40% or lower, then this would allow for no-mold.
Also I didn't take 10 minutes I gave you the answer right away, which if you knew what you were talking about would have been able to figure out.
I've been growing outdoors for 20+ years and indoors for 7+ and I have no idea what VPD is. When did that become "the most important thing"? Someone must have forgotten to tell me or my plants
You just answered your own question...Ohhhh...7+ years of indoor and you've never heard of VPD? If you didn't add that than you would have answered your own question. It just stands for Vapor Pressure Deficit and is generally something that indoor growers know about because they grow in a sealed environment. Were your indoor grows not sealed?I've been growing outdoors for 20+ years and indoors for 7+ and I have no idea what VPD is. When did that become "the most important thing"?

I've seen it in passing is all, and only recently at that. I've always gone by temp and humidity and everything has always worked out for me. Never went by VPD or any other measurement.
do you also do something against spores, as like ozone or UVC lamps? I'm thinking about if I should somehow sterilize all the air at the intake. I've seen UVC lamps do that on water in tubes but I would need something in the range of illuminating a big shoe carton.
Sounds like something additional I don't need to worry about then
