I'm think of using copper tube as a heat exchanger in a DWC 5 gallon bucket. I know Cu is a fungicide. I'm not sure whether it's suitable for this application. Thoughts? Experience?

Copper tube in DWC?

Hmm...
it’s not just a fungicide but is also anti microbial. Also great for killing snails in a fish tank.
As an anti microbial, it would kill the beneficial bacteria that are part of helping roots uptake nutrients. I’m not sure if it would have any negative reactions to the plant, but would be more concerned as to how the copper reacts to all the salts in the reservoir.
If price was no concern, i would try to use stainless steel tubing. If you do come up with a heat exchanger system, I’d be very interested in following along for ideas.

What is your plans for chilling the water? Pumping?
There are some great peltier in-line cooling modules on Amazon that i have been eyeballing. Unfortunately they consume a lot of electricity to run, so I’m looking for other ideas.Over 30 yrs of back pain management without ever having a pharmacist give me a bottle of pills.

So, if this was sitting on the bottom of a bucket and had cold water 40F running through it, would it cool the water to 65-68F? Hmmm
Smokesteve have you ever tried copper in a dwc? That would be the simplest solution. Does DWC require good bacteria if there is no bad bacteria?

I am looking at one of these with an Arduino Nano to monitor temp to turn it on/off.
