incubator will be built :)

First off I was in no way saying Brad was wrong...if you read my posts what I was saying was that there is more than one way in which an enclosed space with high levels of humidity could cause condensation. Like you say above a closed container causes convection which is a differnce in pressure this pressure tries to equalize with an outside force of different pressure - this air movement will also cause condensation.

I stated I agreed with Brad on a way condenstation could occur just not in this case and I stated why. I based my responses on what I was told on this forum about my situation (which is the same as what Gin is going through)...it resolved my issue.

the only thing i've ever incubated are leopard gecko eggs, so eggs this large i'm not sure about

*think about a water bottle that you've left in the sun, at first the condensation will be crazy, but eventually once things level out, there's just sort of a fine mist on the sides.

I agree but what you describe are the two different ways condensation can occur. Also I am fairly certain that 100% humidity doesn't mean equilibrium but the saturation of the air (how much moisture the air can hold). The leveling out that you talk about is what I believe is happening in Gin's case the air inside vs outside is equalizing.

Then your point about eggs is also true (what Brad was talking about) the increaese the temp of the eggs creates a condensation as the eggs have a different temp then the surrounding eggs.

I love your water bottle analogy...but what happens why you open the hot bottle...if sealed competely it will have become pressurized (very little but you will still hear it usually)...if not sealed the bottle will actually shrink somewhat...these are the gas exchanges you are referring to.

It is all good and Brad and my discussions were to help all.

Brad if I came off to strong my apologies as I didn't mean to. Just discussing options :D

it sounded a little dismissive to me, but no matter, i was no part of that, the real test is if brad felt that way.
saturation=equilibrium

I am just really worried about potential condensation dripping onto the eggs. i cannot lose another clutch due to my own error; I think I would just kill myself.

Build a little sloping roofed tent over the eggs out of plastic coated wire and a poly bag? I'm only slightly kidding by the way.

If it becomes that much of an issue, you can lay a paper towel over the eggs in the box to catch any droplets of water falling from above.

OK.. I am hoping that the condensation stabilizes; I am not touching it for a few hours and then I will go peek in.. I should have installed a window, and just might into the lid.. :)

gin, i would mix up the vermic and set your boxes up. make sure they are airtight. the vermic will act like a heat sink and help keep the boxes stable. let the helix run, eventually everything will even out close enough. if your bator is over 3-4 ft tall, i'd add a small fan, 30 cfm's or less.


i'd set the helix to 88, better to error on the cool side, imo.

let the helix do it's thing, give it a day or two to stabilize.


good luck.

The window is definately one of the best ideas I've heard - I intend to retro fit one to mine. If only I could fit a small light inside as well but not possible with the design I have at the moment.

del, led ligthing very very tiny and no heat output!:D
