The Mini Digital Hygrometer is great for spot checking conditions in your growing area, and can also be thrown into curing jars to monitor their humidity and temperature! This handy little unit takes the guesswork out your operations without breaking the bank and can also be built into propagators and incubators if need be. Keep one inside your grow area, another outside and compare the temperature and humidity… so many uses!

With its compact size of 48 x 28.6 x 15.2 mm this unit will fit almost anywhere.

For a more advanced understanding of how temperature and humidity relate, you can learn more about vapor pressure deficit VPD here.

Handy Tip:

Use a Boveda Humidity Pack with your unit in an empty airtight jar to find out more about the factory calibration of your specific mini digital hygrometer – make a note of what your hygrometer reads after being left in the jar for a while against what percentage Boveda Pack was put into the jar with it, for future reference.
