Cool Coil thermostats?:happy Nice! I'm going to have to give Hydro Innovations a call...:phone-2
Restricting the flow to the cool coils with the ball valves works but, it would be nice to have them fully automated...:character0180:
Ben, thanks so much for your informative reply to my questions regarding chillers - I (stupidly) thought that PG would help the water stay cooler through the use of "magic", or some other such nonsense that was floating in my head.
Regarding my other point of automating them, though, I think you might have missed the point - attaching a Ranco controller with a solenoid (like the one I'm gonna have to hook up to my water-cooled CO2 generator) would allow you to dial in the temps to every reservoir without going through the hassle of trial and error by opening and closing valves.
Again, not trying to overstep my bounds and give you pointers because I really can't even hold your jock strap, but I'm pretty sure that idea would work great.
The attached solenoid wass about $30 off of eBay - needs to be wired to a plug (another $5), but even my incompetent ass can do that.
Plants look fucking amazing.
