micksmelanie:

rdl:
Most cheaper hygrometers are going to use an electronic sensor and you pretty much have to go on faith that the specification given is reasonably accurate. Calibration or verification of such a device is a bit of a pain.

Couple of years back I grew some lettuce on my kitchen counter and some nice bell peppers in the bedroom closet. All done hydroponically, no hygrometer required.
