I bought a digital temperature / humidity gauge w/ a probe. If I have a temp gun and a herpstat working my UTH do I still need that thermometer if I have my temps dialed in? If so, do I need a thermometer for both the hot side and the cool side? Do most people bury the probe in the substrate and keep the thermometer inside the enclosure or outside.
Here's the one I purchased.
