Humidity issue

I have 8 of these at the moment and I had the same problem.  It has to do with the fact of the internal fan placement of the cc-300.  Unplug the unit and you will see all of your numbers even out.  If you must run it (A/C)  perhaps you can block the airflow.

The problem, as I can best tell is the internal fan runs 24/7, even when not cooling.  It pushes the air into the center.  Perhaps it is pulling the air from the top and bottom and pushing it to the center. 

There is no need to add fans.  As long as you place your beads/packs evenly around, there is no need for air circulation.

Make sure the drain hole is plugged as well. 

Yeah but i need the unit to be running so it keeps the temp at 65 inside. Outside temp is 80.. i dont know if i can only turn odd the fan but keep the cooling system on??

Oh man. How did i forget to mention that?!? I fought ***80%+*** rh in my wine cooler when i first set it up in my old swampy summer basement apartment. Finally found that unplugged drain hole and felt like a doof for not noticing it sooner. Everything was kosher after i taped that bugger up. 

I got my drain hole closed the moment i got it

What are you guys using to close/plug the hole?

I just taped it.

Had somewhat similar issues with my CC-300. Took a laptop cooling fan and mounted it to a dress box lid. Wired the fan to 6' length of flat ribbon cable, so I could run it out the edge of the door without leaking air, to a USB to 110v adapter. Plugged this into a 24 hour timer that goes off every hour for 15 minutes to move air around. No more variances top to bottom.

Not sure that this addresses your specific issue, but it might provide some insight....

 

I watched a test preformed by Boveda and Xikar that placed one set of boveda bags in a plastic tupperwear container and another equivalent set of beveda in a plastic ziplock type bag.  I would estimate that the volume of the area inside the bag was roughly equivalent to that of the tupperwear container. They placed a calibrated hygrometer in the plastic bag and got a humidity reading.  Then, they placed the same hygrometer in the tupperwear container and obtained another reading.  The test allowed for enough time to pass such that the air inside the plastic bag and the air inside the tupperwear container would have to time be properly "saturated" with moisture from the boveda bags. T

Result: the humidty readings were different between the plastic container and the plastic bag.

Explanation: something to do with air circulation and the differrences between plastic bags and tupperwear? Maybe Midi-chlorians?

Perhaps, as @NotLawReview mentioned, there is something going on with the airflow in your humidor that creates differences in readings similar to the bag/container experiment?

I also like @Monterey explanation.

Just some food for thought....I am wrestling my own humidity issues as well.  For some reason the humidity will not stay at 69% in my newest desktop humidor despite using sufficient boveda packs.  If I put distilled water in the humidor the humidity will rise and stay fairly consistent.  However, when I take the water out and use the bovedas, the humidty drops to around 62 as tested on three different analog and digital hygros....I was hoping that buying a boveda humidor and using boveda packs would elliminate this issue

In this case I think it has less to do with circulation, and more with the rate at which water vapor can escape.  Water vapor can escape a ziploc bag faster than it can a tupperware container.  Also, I assume that the rate at which a boveda can release water vapor is a function of the difference between its rated RH and the RH of the air around it.  So, they settle at an equilibrium.  Since the rate at which RH can escape a ziploc bag is higher than the tupperware, the ziploc's RH equalibrium point is lower than the tupperware's. 

Hope that sheds some light on it and I hope I explained my thoughts in a coherent manner.  🙂

@MattxGYou took the words right out of my mouth.  The test video went into some of that but I did not retain much. I wish I had though. If true, I am surprised by the significant difference in the vapor release rate of the two containers. I thought those bags were air tight???

 

What does all of that mean for someone like me trying to regulate the humidity on cigars?  Does the equilibrium point have an impact on the number displayed on my hyrgometer and the level confidence I can have that I am keeping my cigars safe?
