Really? And I'm the jackass who doesn't know what I'm talking about, huh?
when is cold too cold?

Everybody knows that the canopy is always warmer than the floor.

Bitch move is not a nice thing to say. He only mentioned stupid land, which who knows could be a nice place.

Call it what you want then. Selectively using information and denying while trying to discredit other relevant information is a bitch move in my book.

Lol, too dumb to realize that is my job, you are the one who can't understand.
You are equating wetter = "holding more water", but that is false.
wetter = holding a higher % of water compared to capacity
20RH is just as wet at 50f as it is at 100f. They are both by definition holding 20% of what they can hold. At 100RH it will be raining and truly wet regardless of the temp.

No it doesn't sorry. I know all about the gas laws and vapor content of air, psychometric charts are our friend, but thanks lol. My question was more as to why it's done to the effect of the plant not "I can so I do" lol. Again trying to understand this whole argument that growing in extremely cold temps (sorry, colder than what is recommended for optimal growth) will produce comparible results. If that is the case and can actually be explained then I'll be the first to run out and turn down the stat on my heater.Like has just been said, at higher temps the air can hold a lot more moisture then it can at colder temps, my grow rooms cold due to we're I live and we're it's situated in my house so I keep humidity as high as 70% because in theory In warmer tent with the same amount of humidity (moisture in the air) the relative humidity would be less low because the air can hold more, so I compensate a little I guess
Does this make sense?
Any one care to give a more scientific explaination? Or tell em if I'm wrong ? I havnt looked into cold growing as much as Rex and others I only do it because I have no other choice and I would advice the same to anyone else

You're correct and still don't understand it.

You have that backwards actually. You got it right the first time.So to anyone who thinks 50 RH is drier at cooler temps than higher temps, is that true at 100 RH too? Is it less wet when it's raining and cold than when it's raining and warm?
Here Rex :
Which temp can hold a higher percentage of water? Go ahead.

Let's try this.
Which temp is more easy to increase humidity? 50 or 70?

No man, you said "there is no difference in growth from 33 degrees to 80 degrees ". You can sit here and try to twist the words all you'd like to, but what does optimum mean? It means the best conditions, so if there IS NO DIFFERENCE between 33 and 80, then YES you are saying 33 is optimum.
This is really crazy, anybody who's grown for any short amount of time should know this. I deal with cold a lot and I'm not speaking from inexperience.

Still stumped huh?
Let's try an easier one.
If something is wet, would it dry faster in a 50 degree room or a 70 degree room?

Easy, neither, in both cases you just add water. You add less water to make humidity go up in lower temps, aka you need less water to make it wetter. You are thinking wetter = more water, that is not true, that is the 2 year old's understanding of wetter/moisture.

I'm no expert but Id say at 50 you have to add less moisture to the air/grow room to get a 1% increase than you would at 70? But at 70 the air can hold more moisture so it should be easier to raise the humidity? And I'm guessing it's the same princable for lowering humidity?

Optimum is what you, you're own personal preference, recognize to be right. I grow plants at low temps fine. You grow them at high temps fine. As long as both plants grow unaffected by temp, then the plants are growing at an optimum rate.
This is about the plants, remember? You're personal temp preference has no sway on what the plants can thrive in.

No, that's not what I'm thinking at all. I'm thinking that a colder air is a denser air, which means restricted movement of molecules over any given volume. That just happens to mean that a colder air can hold more water, oxygen, and CO2 molecules by volume than a warmer air by volume. Ask any drag racer about cooler, denser air.

You're right on the first half. It takes more moisture to increase the humidity in 70 though.

That makes sence because the air can hold more moisture it takes a higher amount to increase percentage, I suppose u could say 50 is a 500ml bottle and 70 is a 750ml bottle is will take more to fill the 750ml to half way then it will to fill the 500half way?
