A lot of you already know this, but some still do not.
Condensation is NOT, i repeat; is NOT an indicator of Humidity. Condensation on the sides of your chamber simply means that the sides of your FC are cooler than the water vapor inside the chamber.
Copied and Pasted:
"Water vapor that naturally condenses on cold surfaces into liquid water is called dew. Water vapor will only condense onto another surface when the temperature of that surface is cooler than the temperature of the water vapor. The water molecule brings a parcel of heat with it. In order to have condensed, the molecule tranfers its kinetic energy to the atmosphere. When water vapor condenses into liquid water, the hydrogen bonds form again and release latent heat, which increases the sensible heat and causes the air temperature to rise. Sensible heat is removed from the air and the temperature drops when evaporation is occurring and latent heat is converted to sensible heat and the temperature rises when condensation occurs."
I think the above quote should be put in a sticky on here, its all too common for people to believe condensation is a direct gauge of humidity.
EDIT: I should say, I'm not even close to the first person to point this out on the boards, though usually when it does get pointed out it's in the middle of some random thread that 90% of people don't even see. I point it out once again only for the sake of the people who are still misinformed or mistaken about condensation, and in hopes that the quote i posted goes in a sticky on this board. By the way, the quote was taken from wikipedia, which I understand is notorious for misinformation, but the quote in my above post is 100% spot on for sure.
-------------------- I am the first person to admit that I'm wrong about something, If I post anything misinforming or misleading, do not hesitate to call me out on it. IF I'm actually wrong, that is. I usually wont post something unless i know it to be 100% true, but mistakes happen. If you try to tell me i'm wrong about something im positive of, i will argue with you until you stop breathing.

I'm not trying to rain on your parade or anything but condensation is a great way to "Eye" humidity levels.
Correct me if I am wrong but Mycelium produces it's own heat. Heat rises carrying water vapor in your terrarium above your substrate. Then once the vapor is saturated it produces water dropplets running down the sides of your terrarium. How is that not an indicator of humidity?

did you read any of that?
condensation tells you two things: 1. there is SOME AMOUNT of water vapor in the air 2. there's a temperature change from inside to outside your chamber.
that's it. you can't use it to eyeball humidity, it just doesn't work that way.

Condensation HELPS humidity, that I do know.......but yes I agree it is not a sure sign that things are 95% humid....as pin setting needs to be very humid.

Condensation deos not help humidity. If its not in the air, the moisture no good sitting on the walls.
My bedroom wall gets condensation on it in the winter. Is my RH in the room 95%+??
No, its below 60%. if a surface is cold enough, moisture will condense out of the air onto that surface. Whether rh is high or not.

Well hold on I never said you could eye a percent. I simply said it's a good way to gauge humidity.
If I am understanding the OP correctly he should see most if not all of the condensation near the substrate because that is the only thing producing heat (Which is a small amount anyway).
I was always under the impression that in MOST cases condensation occurs from... well high levels of humidity (water vapor in the air)

But don't be confused, high humidity will call condensation on the walls of your fc.

Right but you are probably running a heater in your house in a cold environment which is why your walls are getting all that condensation. When you cultivate you do not use a heater for many projects that are normal to the board so it's safe to assume you can rule out the heater.

what ? of course it is ... do you see condensation on your glass surfaces in your home ? no because the ambient humidity is probably only about 30 percent jack it up 70 % and you would ... humidity = moisture in air ... how does it get on the sides of your fc , magic ? no it pulls the moisture out of the air = humidity ...

Condensation does help humidity, damn man.
Spray the walls of a container and tell me it isn't more humid when you open it back up!

My sliding glass door has condensation due to me breaking the outer pane of glass, which ruins the insulation of the 2 panes.

Right I think the post should be changed to
"Condensation is not an accurate gauge of humidity"
- Dictionary.com ( Reputable )
The process by which a gas or vapor changes to a liquid. - Condensation.
Now unless you are spraying tons of oust in your room there has to be water vapor in the air meaning that humidity is present.

Condensation is not a sign of correct humidity. For the record, 60, 70 or 80 is not the correct humidity for a FC. 95 is.

Ya, so you spray a vapor and it becomes condensation.
So I also for the record never ever disagreed that condensation is not an indication of humidity.....nor that anything other 95% is your goal...think even 98% for pin set.......but it is hard to dial that shit in spot on without some electronic self automated gear.
This thread should be closed, it is obvious to anyone what is correct and what is not........established

My FC has a humidity of 98-99 all the time, except when I fan it.

That is pretty damn good! Your using a casing? Do you pump in warm moist air? I have yet to tried that.......I would like to make a nice one...well, a good cheap one.

i agree that just because you got some condensation on ur fc doesn't mean its to the correct level but to say its not a result of above average humidity is just stupid .. i haven't used a Rh gauge since my first grow ... cant be bothered ... if you've grown once you know what it needs to be by eyeballing it ... one way i can tell is not by the amount of condensation but the speed in which it forms ... condensation can sit on a surface for ages .. just because you got some beads doesn't mean they are constantly forming ... so for the record i think speed of condensation formation is a 'good' way to gauge humidity ...

Totally agreed, I haven't used a Hygrometer in months. Although whenever I make a new chamber I like to compare.
Treemoss - you don't want any kind of warm moist air coming into your FC. It's a breeding ground for contamination! :> The casing is there to provide a "Micro Climate" raising humidity levels and inducing a "Better" pinset :>
