Why did my RH level drop?

There are a number of things that can affect the RH in your humidor or your RH readings.

Let’s problem solve this together:

  1. Have you calibrated your hygrometer? If not, calibrate your hygrometer with the Boveda One-Step Hygrometer Calibration Kit to make sure your getting accurate RH readings. Watch this video to learn how to easily calibrate your hygrometer.
  2. Did you recently add new cigars to your humidor? Adding new cigars without conditioning them first will definitely affect the RH in your humidor. Acclimate all fresh cigars in a Boveda Humidor Bag for at least 4 weeks before placing them in your humidor with the rest of your cigar collection. (No humidor bag? You can also condition new cigars with a 69% Boveda in any airtight container, like Tupperware®. Or slip an extra Boveda into your humidor every time you add any new cigars—just make sure you don’t mix different RH levels in the same humidor.)
  3. Before filling it with cigars, did you season your wooden humidor properly? Seasoning with Boveda 84% RH is easy and precise. Watch this video to learn how to season your humidor.
  4. Are you using enough Boveda in your humidor? Base the number of Boveda you use on the capacity of your humidor. Verify how many cigars the manufacturer said your humidor can hold, then check here to make sure you are using the right number of Boveda.
  5. Are you using the right RH for your cigars and your humidor? Check the chart below to find out which RH is right for you. Or watch this video to learn more about RH levels.
