I haven't downloaded the specs, I should, damnit. I hate getting things second hand. The thing doesn't read ph. Only humidity and temp. . ...ALWAYS calibrate. Two points is my preferred. I've never used that probe, have you been able to find the white papers on it? It looks as though it's meant to stay in the solution you're probing.
Hi all growers, I am in need of information,please? I got a hygro-thermometer free. Does the probe need calibrated? View attachment 630031 Does this probe constantly sit in water? Is it best to use just for my cloning machine???? I got it free with the free ez-clone. Can't be too much to it???
I wasn't thinking when I first posted, for some reason I was thinking pH was involved. The probe needs to be where you need the temps/RH monitored, right? My GH fan controller probe is in the room. Or, it was in the room.Hey @Seamaiden it says to stick my probe outside. Sounds illegal........ any reason why? I need some more advice.
Ok the digital when breathed on goes straight to 80-90-100% humidity. The other suck ass, and are staying at 50-60% humidity. DamnitBreathe on one of them, see how it changes.
