If you don't need a lot of precision go with a cheap setup like that. Only has about 1 degree of accuracy.
If your air temps ever hit 65 degrees it means your ventilation is terrible. Just don't use a restrictive front panel, and at least 2 case fans.
I have never had good luck with any spring type oven thermometer. Either they are way off from the beginning, or they get less accurate as time goes by. I got so sick of it I bought a multiprobe thermocouple thermometer specifically to calibrate my ovens.
>And yes, i also have an arduino which controls 2 12V rails (Light & air) via mosfets which is connected to a humidity and temperature sensor
Well, who else here is going to do that? You keep missing that point. I don't care what you or I can do. I've got about a dozen Aduinos, dozens of sensors laying around, etc etc. Big deal. I care about what others can do so their problems can be solved.
Most people here are beginners and most don't have Arduinos, they just want to grow some pot. You are completely missing the point about others not being able to even duplicate a simple 555 timer design- I don't care if you can and already assumed you could.
>very sensitive to the vapor pressure in a high light environment (Which does not exist if the light is off)
This does not matter if plants are freezing to death when the lights go out. You are also missing this point. A common question is "can I grow out in my garage in winter". Now solve that problem without using an Arduino.
But I'm running tests. I get about a 1 degree F temperature rise for every 1 watt input with a power resistor (peltier module) in a five gallon bucket with no extensions. I'm using a four input temperature meter calibrated to a Fluke 287 that is calibrated to an ice bath.
I'm also doing testing with a 55 watt UFO in a bucket with a single 40mm exhaust fan at 0, 4, 6, 12, and 14 volts (because you can buy a cheap variable power supply so the layman could duplicate this). I'll post results later on a separate thread since you got me curious about this.

BTW, I got my hands on the Teesy 4.0 it's really a remarkable Arduino controller being super scalar at 600 MHz. This is a deal at $20 and you should pick one up.
edit- little bit of grammar
