Humidity Observation
    #4088618 - 04/23/05 03:44 PM (12 years, 3 months ago)

In most teks, the humidity levels are listed at being somewhere between 85-95% humidity, though through my trials ive observed a certain trait of humidity. In the situation of a closed chamber, as long as something maintains some amount of moisture, humidity will always sit at 99%. i take this to be that as long as their is water in a closed chamber, the saturation of air will be maxiumum. This means that misting your box after fanning it out will only serve to oversaturated the ambient air unless of course your casing is nearing complete dryness. One person i talked to said that optimum humidity levels are when the sides of the container have a light mist on them. This however doesnt make sense, as that would mean that the air would have to be saturated enough to condense, well above the desired levels.

So the ideal humidity levels of 85-95% are unrealistic, unless your willing to let your casing dry out to a most undesirable level.

My observed recommendation is that their should be no condensation on the walls of your chamber, and if any starts to form, it should be wiped off to reach a more desirable levels of humidity. The casing should be lightly misted every so often untill pins start to form, as i was told that misting pins causes them to abort.

Condensation on the walls of your terrarium doesn't necessarily indicate Rh at any specific level. Could be 100%Rh; could be 65%Rh. Its the difference between air temperature from inside the terrarium and outside the terrarium, with the addition of humid air, that creates condensation....

You were told wrong.

Hitting them with a direct blast at close range will cause problems but a light misting is beneficial.

you learn something every day.

Well, the case with me is that the only thing in my chamber is one small casing, and my hygrometer is always sitting at 99, unless i fan it out, which is drops 15% then slowly climbs back up. I figured that the little bit of moisture sitting on the top of my casing is making the air saturated. can anyone explain this to me? i mean, my room humidity sits at 30%, so its not like my hygrometer is broken or my room is humid. Something has to be making the chamber humid, and i always keep the walls of the chamber dry.

In the situation of a closed chamber, as long as something maintains some amount of moisture, humidity will always sit at 99%.

This is partially true.

For water vapor to condense, the humidity must reach 100%, by definition. It can't be otherwise. However, it's possible for the humidity in the immediate vicinity of the walls of your chamber to reach 100% as the chamber wall itself cools below the dew-point, while the rest of the air volume away from the walls is below saturation.

Generally, though, if you see condensation on the walls of your chamber, and there hasn't been a rapid temperature drop recently, you can assume the humidity in the chamber proper to be close to 100%.

Good luck!  :mushroom2:

everything is going fine at 99% hum, with or without condensation on the walls. Perhaps the teks should be admended to say " fruiting humidity should be above 85%" instead of giving a range.
