Humidity issues.

Post number #2 is wrong.

What happens to humidity when temp rises?

If the water vapour content stays the same and the temperature rises, the relative humidity decreases. This is because colder air doesn't require as much moisture to become saturated as warmer air.

This is totally different than what you said in the first place.
What?!?

I said I’m not having issues with the lights on. Meaning my RH is in a good place when the lights are on 40%ish

the rh of my grow box is gonna be the same as the rh of the rio. It’s in. They both have the same air.

Exactly. Sorry Aaron, but I gotta argue with Post #2, :lol:. I already explained it in my stoner way, lol.

Yes... RELATIVE.

I guess we are growing in different environments... Sounds like you are open, and Im sealed up tight....or have been anyways. Sealed RH seems to react differently to me that fresh air intake. I have no scientific evidence to prove that. Sealed, CO2 fed air reacts differently than fresh air intake. Im sure there are other things at play that will affect dew point, RH and temps opposed to sealed up, with no fresh air, and fresh air intake..... more research should be done.
