That makes more sense, with more water you get the benefits of the larger stable temperature mass.

I'm going for it, I'll post on the results...

I should clarify by 2 inch of water....
It is 2 inch's up the side of the carboys
With the long "tub" i have it takes about 3 gal of water or so to get the 2-3 inch of water up the side of the carboys. the tub is only about 6 1/2 inchs high but it works like a champ. Everybodys setup differnt.

Just "play" around with what ya got and you will quickly find out what works best for you.

Good luck

Cool, thanks for the clarification - it all makes good sense. I've heard of people strapping their fermenters in streams to keep the temp down... seems risky to me - I think I'd always go outside and be 1/2 surprised to even see the fermenter still there...

I'm swamp cooling this weekend thanks to you guys!

So how are you guys taking the fermenting brew's temperature? Are you running a long thermometer in the airlock hole, or what?

I always just assumed those things were a gimmick. If it is stuck on the outside of a warm plastic (low thermal conductivity) bucket, immersed in a cool water (high thermal conductivity) bath, or covered by a really cool wet T-shirt saturated with evaporating water, isn't it going to constantly read low?

Has anyone benchmarked the stick-on thermometer with a direct reading of the liquid inside the fermenter?

I have an infrared thermometer, in my experience the temp inside and outside the fermenter is about the same even with a plastic pail, so the stick on fermometer should give you a good reading.

If you use a 5 gallon water bath for a 5 gallon batch, and room temp is 68*F, your water bath will be about 66-67*F due to evaporation, and your fermenter will be about 68*F inside. If, on the other hand, you just stick the ale pail in the 68*F room it will get up to 74*F or 75*F inside.

Stick ons have got me through many batches with no problem. You do need to shine a light on them to read them if you have your fermenter in a dark place though.

I have the opposite problem in the winter, my basement air is 65, but the basement floor is less than 60, so any carboy sitting on the concrete goes dormant due to heat conducting through the bottom. Any carboy sitting on a shelf or a book does just fine.
