I live in a hot, humid area, and it’s dead middle of summer. I have had problems with root rot unless I chill my water somehow. I have a big mini fridge that gets so cold it freezes water completely. I was thinking about making a stainless steel wort chiller, dropping the coils in a metal stockpot of water, and running it through the mini fridge from and back to my reservoir to cool my RDWC nutrient solution. I was thinking about 25 feet of 3/8 tubing, but I’m not sure what size water pump. Would this be effective for 15-20 gallons of nutrients? My reservoir and containers my plants go in are insulated with great stuff foam, and covered with Mylar (no Mylar on reservoir it’s outside grow area). Anyone tried this or have any suggestions?
I was thinking the nutes would cool quickly because of the metal transferring temperature, and the water around the tubing would be frozen in a day or two. So, I hope it would be effective in keeping my root temps down.

*I have had success using frozen milk jugs, but got tired of switching and cleaning them. I had used about 30 foot of polyethylene tubing coiled in a plastic container and then put inside a mini fridge before, and it worked pretty well. But last time I had hell with the water pump pushing it through the coils and back into my reservoir. I think it was kinked somewhere I couldn’t see.

I have brewed beer for years and the slower you run the water through the wort chiller the better it works. Also if making your own make sure to leave at the minimum a .5” gap between the pipe.

I have considered doing the mini-fridge and wort chiller combo myself but haven't yet put too much time into it since I was spending my time getting my initial setup built and going. It is about time for me now that the plants are going to circle back around to this.

I also have considered something like a peltier coolers to build my own cooling reservoir.

Leave a gap between the coils or where?

Yes between each coil, I’ve done this myself before and it really helps allowing air/ice water between each. I mean by done this myself before I mean made a copper wort chiller and kept no space between. It will work but you will get better results. Again you don’t want to much gap because the more coils you have also better.
