im trialing my incubation container with the no substrate method (water and 2" pvc couplings),but there is ALOT of condensation building up on the plexiglass lid.is there any way to combat that or will the eggs when in the container start to absorb that excess moisture and keep the plexiglass clearer of condensation

but only 75% humidity consistently

glass. on the inner part where the eggs would be,so it would have the potential for water to drip onto the eggs themselves which I want to prevent

I used the no sub method for the first time this year, and had a similar problem.

This is what the egg box would look like in half a day after wiping it dry.

It never caused a problem, or dripped.
once a week I exchanged air, and lifted the plexi at 45degrees and used my finger like a squeegee to push the water down.

I don't wave a pic of how bad it was at the end of the week, but it never dripped.

hope that helps

You temps are uneven causing condensation on the cooler surfaces. Adding a heat source to the top of the incubator or adding a fan may help even out temps.

Thanks Jaremy,

I built that thing one morning, got my temps stable in the afternoon, and had eggs for it that night.

I am the classic procrastinator.

That clutch hatched a few weeks ago, and I still havn't messed with it yet.

There is a top for the incubator(not on in the pic), and the egg box outside/inside temps were within a degree when the lid was on.

It still must have been enough variance.
I'll try a fan this week, and see if that helps.

thanks again

just so you know plexi has a huge tendancy to bow when you have high humidity on one side and dry on the other. I would go for glass if I was you. Its not expensive, and a craft store will cut it for you in their picture framing dept.

That's what you want to see.If i don't see alot of condensation,then i even add a layer of plastic wrap up under the lid.
Lean the eggboxes a bit by placing some sort of wedge up under it on one end(so that the rain travels down the inside of the lid and falls into the end).This is where perlite comes in handy.It keeps the eggs level in the box when it is leaned,(since it all floats).

This is a pic from last spring.

The eggboxes i used this season were not as tall,with less perlite as well...
The ratio is unimportant.The trick is to have enough water for it all to float,and a thick enough layer of perlite so that the plastic grid does not sink due to super-saturation.

The top one in this pic,is the minimum size box i found it possible use for eight eggs(this season).(The lid on it was superior to the two below it as well.)
