Reddit mentions of The Weekend Brewer STherm7 Stopper Thermowell

You could carefully cut a bigger hole in the bucket lid, then install a bung with two holes. The airlock goes in one hole and the thermowell goes in the other.

They make them for use in glass carboys. Here’s the one I have. Be sure to measure the thermowell length to see if it will work on your set up (go into the beer) and that the interior diameter works with your probe.

I don’t know this seller but I see this too on Amazon.

Edit: another idea is to keep the existing airlock hole and airlock but also cut a bung hole and add a bung with one hole into which you insert a thermowell.

I wouldn't drill the lid for a thermowell and ball lock port. There are a combo action of items on Amazon you could get and utilize the bung hole that already exists.

Drill a 1/4" hole in the undrilled stopper for the carb cap and you have a ball lock connector.

The bung with the thermowell works great on my anvil fermenters.

This would probably do the trick. I use the #10 one with my fermonster.

Something like this

If you are fermenting in this, just taping the probe to the side will get you pretty close. But a more accurate temp reading would be with a thermowell. Like this one where the probe goes down inside the wort but stays dry.

For temp control, you want something like This to control your heating/cooling, and a Carboy Wrap to heat your FV up.

If you get a thermowell you can put the temp probe down in your fermentation vessel, rather than just taping it to the side - you'll get more accurate readings. Downside is you can't set up a proper 1" blowoff hose, and counter-intuitively the first few days of fermentation (When you really need a blowoff hose) are the most critical to temp control (Based on what I've read in other threads here)... Might work well if you get a 6.5 gallon carboy, and do 5 gallon batches in it, so you've got extra head space for all the krausen. You can also use some standard size siphon hose as a blowoff, it's just more prone to clogging than 1" hose.

They make bungs with thermowells you can put the probe into, like this https://www.amazon.com/gp/product/B01KP4D0K2/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1

Keep in mind that ambient temp can be much different than your beer. A relatively cheap and easy solution if you have the room: a $50 deep freezer from Craigslist (I was amazed at how many I found) plugged it into this , then use this on your carboy.

Drop in your carboy and you’re good to go.

Edit: Woops. I missed the “no room” part. Good luck

That particular probe looks like it has some nooks and crannies that would be a perfect place for bacteria to hang out. (i.e. The connection point of the wire and metal tip) If you insist on submerging the probe you should check out this stopper/thermowell combo. I’m going to assume that the vessel you’re fermenting in has a wide mouth opening, however the thermowell in the link is removeable and could be adapted to your set up with a little creativity.

I was gifted an Ink Bird ITC-308. It comes with a temperature probe.

Wanted to get a couple of these two spout carboy caps so I can easily swap out the prob to different carboys as they cycle through without haveing to swap out the entire cap as you would have to with these caps.

I can't find the thermowell tube on amazon. My LBS only had one of the stopper thermowells. Anyone have suggestions on where I can pick up two thermowells with fair shipping prices? I will be using mostly 5 Gallon Carboys but due also have a 3 Gallon Carboy I hope to use.

Buy a thermowell, solved all my problems: https://www.amazon.com/Homebrew-Stopper-Thermowell-Weekend-Brewer/dp/B01KP4D0K2

[these are great] (https://www.amazon.com/dp/B01KP4D0K2/ref=asc_df_B01KP4D0K25278173/?tag=hyprod-20&creative=395033&creativeASIN=B01KP4D0K2&linkCode=df0&hvadid=167141564589&hvpos=1o2&hvnetw=g&hvrand=10949363970535221182&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9004056&hvtargid=pla-306155074925)

This one works great for me with my itc308 and NB BM bubbler.
