I'm trying to find an accurate hygrometer, which is proving to be difficult. Which one do you use/recommend? This will be for my mantis enclosures, so the smaller the better.
I read that thread, and I am surprised that no one has mentioned the salt trick.
I just skimmed through so I apologize if I missed it somewhere. Can the DYI ones be used above ground or just strictly in soil?Buy one such as http://www.vegetronix.com/Products/VH400/
Make one like http://gardenbot.org/howTo/soilMoisture/
Or get a good multimeter and an appropriate moisture sensing probe. I used certified, calibrated Fluke meters at the hospital for just about everything from HVAC to IFM calibration.
