Condensation issue

[lukeo97]

So I have 4 enclosures in one big enclosure with a heat Matt underneath,

the thermometer says it’s ideal humidity, and temp for my tarantula and my scorpion but both of the containers they are in has condensation in the plastic tubs on the top and the sides, I’ve made holes on the top and sides but still loads of water drops on the inside lid,

how can I stop this? And if it needs more holes how do I know how many to do?
could the soil be too wet? Even for a forest scorpion?

they have only been rehoused about 48 hours ago is it okay if I move them etc?

what would you do in this situation?
I wanna provide the best housing for my new animals,

thanks for all the advice in advance

Do not place a heat mat under it, it should be on the side of the larger enclosure. Have a read at the thread in my signature concentrating on the Temperature and humidity section.

so is that all it could be? I was told to put it under neath from the reptile store I went too not long ago

Yes, it's is heating and evaporating any fluids in the substrate. Moving the heat mat to the side of the enclosure will help but it won't completely stop it.
You're substrate should be damp but not wet, if you get a handful of substrate and squeeze it, there should be no water dripping from it but should feel wet.

For tarantulas at least, putting heat under the tank KILLS, it’s 100% guaranteed

Ambient Heat is a safer alternative.

What is your room temperature?

 

[Smotzer]

Can I ask why you are trying to heat them up? What are your temperatures? Generally the wide array of room temperatures are fine for tarantulas with out any need for external heat. I’m curious where you were told you need to heat more?

If your substrate was fairly moist when adding it to new enclosures and then was heating them you’ll see more condensation in general.

What is your room temperature?

Yeah. Condensation occurs when the temperature inside the enclosure is higher than outside.

Do not place a heat mat under it,

Zing. That's rather cute. A miniature weather system complete with an inversion layer. Move your humidistat down to the scene of the action. directly above the substrate or best, have two such sensors. Your sensor is up in the inversion layer of cooler dryer air. Warm air holds more moisture than cooler air. Cool dry air traps warm moist air beneath it.
Do what A.C. suggested and you'll break the inversion layer. Have a read on the Dew Point. Expect your temperature as reported by your sensor to rise, sometimes quite dramatically.

Around here in the tropics you can have a cloudless day and go under certain trees and it's almost raining. Upstairs the cool dry air is holding the moist warm but heavier air trapped near the ground. That air seizes any opportunity to loose some of it's water to the point where even heavily shaded trees will condense it.

PS An interesting trivia tidbit. The worlds worst weather pattern is along the Ivory coast of Africa. A continuous inland inversion layer that gets blown apart near the shore line. The warm moist air shoots up like a rocket as high as 35,000 feet or more, gigantic thunderhead cumulus clouds developing at an astounding rate. Sometimes in minutes. Don't want to be in an airplane going through those.
