After reading another thread here I became intrigued with the idea of cooling a terrarium to give a more natural drop in night time temperatures. I thought I'd start with items I had and experiment with them. I have a complete peltier unit with cold and hot side heat sinks and fans. I also have an unused terrarium I bought on Kijiji some time ago. I'm aware that cooling the air will not bring down the temperature an acceptable amount. So while I wait the 6-8 weeks for a water block and other parts to come from China I thought I'd play around. Here's my terrarium with some weatherstripping added. I had some extra 6mm baltic birch plywood so that will become my top for now. A Google search tells me the R value is about 0.3. I had an extra 10A power supply in my parts bin so that was wired up.

Hi Yukondave,
I love your idea I work on a project with peltier united me too. Very similar to your.
It takes me time because i use only recycled parts..

Interested to hear what temps you can get. Is it a 10 amp Peltier unit?

Here's the overnight temp/humidity, pretty underwhelming.

So about <2°C of temperature drop?

So about <2°C of temperature drop? Yeah, the normal night time drop is about 1°C.

Interested to hear what temps you can get. Is it a 10 amp Peltier unit? The seller listed it as a 12706 so I assumed 6A. This is the stabilized reading I get which I think is normal for the 6A version.

Hi Dave - Sorry to hear of your results. Don't worry though, that sounds about right from my experience as well. I always want thermometric cooling to work better than it does. I love the precision of your data collection though. That's really awesome!!!

Yeah, when you boil your beer you need to cool it quickly after. People will use coil like that and run cold water through it.
