Thanks for the ideas/input!! Decisions, decisions! The reviews are a little sketchy on all these Chinese controls, but it's got to be better than freezing gallon water jugs to keep the res cool like my last grow. I think the mini fridge setup will work well!!Looking at some of these also.
This one has 2 separate probes that can be programmed separately, heat or cool or both.
Inkbird can only do 1heat/ 2cool but has pump delay for AC/etc.
Both are 10 amp,
This WILLHI WH-1803C is a nice unit for keeping something an exact temp , compensating for thermal lag automatically.
It's an actual PID Digital Temperature Controller, but Heating only at 5A.
Nice for sous vide, seed mats but not a big power draw like an exhaust fan.
I got one of these Digiten units because it has a waterproof stainless probe, which the inkbird does not unless you get the "S" unit with the shorter plastic detachable probe.
The Digiten has a standard probe you can replace with other mfgr, inkbird says no!
I think you can get an even longer stainless probe direct from Digiten.
Going to go dust off the nutriculture and replace some nozzles, maybe get it set up.
