With co2 between 1000-1200 you should be running 86 degrees to get the benefit from co2.
I don’t run co2 I run temps between 80-82 at 60% humidity. My co2 is around the 450-500 range.
Isn’t 60 percent a little high?

Sorry dude I didn’t see the prior messages 
I get it
I’m like paranoid of mold.
VPD says I can do 40 Rh and if I keep I dehumidifier on auto it stays at 40rh.
Its not meant for grow tent.
Keeping 60rh would be very difficult with what I have

Nope, not at those temperatures.
Temperature has a huge factor as to how much moisture evaporates. On a 86 degree day how fast does water evaporate off the driveway.
60% at 70 degrees is too much and MIGHT run into trouble.
It’s a relationship between the two.
77 degrees at 40 Rh?
If I have to I will try for 60rh but it’s going to be tough.
But obviously what I’m doing is not working.
Yeah my VPD chart was wasn’t like this at all.
Thank you!

I tried to get a better picture but this might help you.
With co2 you need a grow room that is dialed! Can change every parameter with absolute accuracy.
It’s why you don’t see much of it in home grows, it’s difficult.
Show me yours?

Looks like a hell of a setup.

How I like to remember VPD. 80/60
Those both need to change 1 point in the same direction.
82/62 75/55 this will keep you in a good VPD.
No it doesn’t need to be perfect… don’t pull your hair out trying just having a rough idea where it should be.
This also includes nighttime temps, if the temp drops the humidity needs to follow.
Most problems with mold/rot come from night time temps going lower and humidity spiking.

Chris have you been to my grow thread?
No, what is it?
I brought the temp up and humidity
I need night time temps for what I’m doing? Coco_auto
Nevermind you said to prevent mold
Although mine are 23 on 1 off

As long as lights off temps don’t drop and humidity doesn’t spike high you will be fine.
