3 rdwc systems one water chiller?

I have 3 4x4 tents with a system in each with 4 plants and one res bucket outside each one.. I have a aircon in the room outside, but struggling to keep the water temperature down.. Is there a way to connect one water chiller to all 3 systems? Will a coil in each res bucket be effective? Think I've read that a copper coil will corrode in the nut water?

Ya, there's ways to do it. Search the forum a bit. I know there's posts on it.

Use a stainless wort chiller coil.

If the chiller has enough BTU/hr to handle the heat load then it will work, if not then it won't.

The real factor here is how much water is in each system? 20gals? X3? What's total water volume for all 3? 60ish?

So this was my cheap diy solution to cool both of my systems. the pump in my veg system was a heater at the time and it kept it within a few degrees of what the flower system was set at.
The res on my flower system is a huge 55 gallon tote. It worked great for this purpose when i needed it to.
I ran another pump with black tubing with foam pipe insulation from 1 system over into the res of my flower system thats on a 1/4HP chiller. I fed it into the side of the res and split it out into a bunch of 1/2" clear tubing(cheapest and inside a closed res so not concerned about light). It stayed a closed loop and dumped back into the veg res chilled. I kept adding tubing in the loop until I was able to get my desired temps.
Eventually I coiled all of it up into a 5 gallon bucket inside my res (dont have pics sry) and let my chiller return waterfall into that bucket before dumping into the res.
So, big res on 1 system with 2 loops like this in it would work with enough tubing, the right water volume, and right sized chiller.
these are the only pics i have of it really.

Right.. I think I might just get a bigger air con.. The one I have now is 8000 btu.. I think it will be enough with a 12000 btu one..

Work or money.
Everything in hydro takes a good bit of 1 of the two.

Unless your tents are reaching like 85F, cooling them down won't help your water temps much. You'd probably see a bigger difference by insulating them.

If you're running an ac, route flexible duct from it and have it blow directly on the water in the reservoir. My water stays at 68 by doing this, regardless of room temps.

I have allready insulated my system.. I found a used
12000 BTU ac and it keeps it nice and chill there now :)
