How to Season a Humidor: A Step-by-Step Guide
A new wooden humidor needs to be conditioned before it can maintain a stable environment for cigars. When the interior wood is still dry, it can absorb moisture from the air and from the cigars themselves, which makes humidity harder to control. Seasoning prepares the wood first so it can support normal storage instead of competing with the cigars for moisture.
If you are learning how to season a humidor or how to season a cigar humidor for the first time, the two most common approaches are using 84% Boveda seasoning packs or seasoning the box with distilled water. For most beginners, the Boveda method is easier because the humidity level and timing are already defined, while the distilled-water method requires more judgment about how much moisture to introduce and when the humidor is ready. This process mainly applies to wooden cigar humidors, especially those with unfinished cedar interiors.
Why Do You Need to Season a New Humidor?
A humidor does more than hold humid air. The wood inside it also absorbs and releases moisture as conditions change, so a new or dried-out humidor can initially pull moisture out of the environment faster than the humidification system can replace it. If cigars are added too early, the dry cedar may draw moisture away from them before the humidor has had a chance to stabilize.
That is why seasoning a humidor is really about conditioning the wood rather than simply raising the humidity reading. Once the interior has absorbed enough moisture, it becomes much easier for the box to maintain a steady environment. This is especially important with traditional desktop humidors, while plastic or acrylic storage containers usually do not need seasoning because they do not absorb moisture in the same way. Electric humidors can vary depending on whether they contain unfinished wooden shelves, trays, or panels.
What Do You Need for Humidor Seasoning?
The supplies depend on which method you use, but the basic setup is simple. For the Boveda method, you need an empty wooden humidor, the correct number of 84% Boveda seasoning packs, and a reliable hygrometer. If you already own cigars, they should stay in temporary sealed storage with normal humidity control while the humidor is being conditioned.
For a traditional distilled-water method, you need distilled water, a clean unused sponge or a shallow container, a small plate or barrier to keep water from touching the wood directly, and a hygrometer. A cigar hygrometer measures relative humidity inside the box, but it is only useful if the reading is reasonably accurate, so calibration matters before you start making decisions based on the number.
You do not necessarily need a dedicated humidor seasoning kit if you already have the correct humidity packs or distilled-water supplies and a working hygrometer. The important thing is to avoid tap water, scented cleaners, soap, or household chemicals inside the humidor, because these can introduce unwanted residue or odors into the storage environment.
How to Season a Humidor With Boveda
Boveda is one of the easiest ways to season a wooden humidor because it creates a controlled humidity environment without putting liquid water directly on the cedar. The process uses 84% seasoning packs for 14 days, after which the humidor can be switched to normal storage humidity.
Step 1: Empty the Humidor
The humidor should be empty of cigars before you begin. The higher humidity used during seasoning is intended to condition the wood, not to store cigars. Leaving the wooden components inside helps the entire interior reach a more even moisture level before normal use begins.
Step 2: Calculate How Many 84% Boveda Packs You Need
Use one Size 60 Boveda 84% seasoning pack for every 25 cigars of total humidor capacity. Base the number of packs on the stated size of the humidor rather than how many cigars you currently own, because the goal is to condition the full interior space and its wooden components.
| Humidor Capacity | Size 60 Boveda 84% Packs |
| 25 cigars |
1 |
| 50 cigars | 2 |
| 75 cigars | 3 |
| 100 cigars | 4 |
Step 3: Put the 84% Seasoning Packs Inside
If you are unsure how to use a Boveda 84 seasoning pack, remove the clear outer wrapper but leave the humidity-control packet itself sealed. Place the required number of packs inside the empty humidor and close the lid. Do not combine the 84% seasoning packs with standard maintenance RH packs during this stage because they are designed for different purposes.
Step 4: Close the Lid for 14 Days
Leave the humidor closed for the full 14 days and avoid opening it just to check the hygrometer. Each time the lid opens, humid air escapes and the conditioning environment is interrupted. This is also why a high RH reading after only a few days does not mean the humidor is ready. The air inside can become humid fairly quickly, while the cedar still needs time to absorb moisture throughout the wood. That is the practical reason why it takes two weeks to season a humidor with this method.
Step 5: Switch to Normal Storage Humidity
After 14 days, remove and discard the 84% packs, then replace them with the humidity control you plan to use for normal cigar storage. Only after the seasoning packs are gone should the cigars go back into the humidor.

How to Season a Humidor With Distilled Water
Seasoning a humidor with distilled water is a traditional alternative to using Boveda packs. It can work well, but it requires more judgment because you are introducing the moisture manually. The safest approach is to let the water humidify the air gradually rather than putting liquid directly on the cedar.
Step 1: Use Distilled Water Only
Use distilled water instead of tap water because tap water can contain minerals and other impurities that may remain inside the humidor or humidification system. Avoid adding soap, cleaners, fragrance, or any other additive. The goal is simply to provide clean moisture that the wood can absorb over time.
Step 2: Add a Passive Source of Moisture
Dampen a new, clean sponge with distilled water so it is moist but not dripping, then place it on a dish or protective barrier so it does not touch the wood directly. A shallow container of distilled water can also be used. The purpose is to raise the humidity inside the closed box gradually and allow the cedar to absorb that moisture at its own pace. Avoid soaking or heavily wiping the interior because too much direct water can lead to swelling, warping, veneer damage, or changes to the seal.
Step 3: Close the Humidor and Let the Wood Stabilize
Keep the lid closed as much as possible while the wood conditions. Traditional water seasoning does not have one universal completion time because the result depends on how dry the cedar is, the size of the humidor, the quality of the seal, and the surrounding environment. What matters is that the box can hold a reasonably stable RH after the temporary moisture source is removed. If you want to monitor that properly, a reliable cigar hygrometer is more useful than repeatedly opening the lid to check the interior.
Boveda vs. Distilled Water: Which Humidor Seasoning Method Should You Use?
Both methods are trying to accomplish the same thing, but they place a different amount of responsibility on the user. Boveda uses a fixed humidity level and a defined seasoning period, while distilled water requires more monitoring and more judgment about how much moisture is enough.
| Factor | Boveda 84% Method | Distilled-Water Method |
| Setup | Simple | More hands-on |
| Direct water on wood | None | Should be avoided |
| Standard timing | 14 days | Varies |
| RH control | Predetermined | Requires monitoring |
| Risk of over-wetting | Lower when used correctly | Higher if too much water is introduced |
| Best suited to | Most beginners | Traditional/manual setup |
For most beginners, the Boveda method is easier because there are fewer variables to manage. If you are comparing which humidor seasoning methods work fastest, speed should not be the main factor. A fast rise in RH only tells you that the air has become humid, not that the cedar has finished conditioning. For most first-time humidor owners, that makes Boveda the easier choice. The distilled-water method is better suited to someone who is comfortable monitoring RH and adjusting moisture manually.
How Long Does It Take to Season a Humidor?
With Boveda 84% packs, the standard process takes 14 days. The humidor should remain closed during that period even if the hygrometer reaches a high RH earlier, because the air inside the box can respond faster than the wood itself.
For the traditional method, the answer to how long does it takes to season a humidor is less exact. Some boxes stabilize faster than others, while larger, drier, or poorly sealed humidors can take longer. The most important thing to understand is that the hygrometer measures relative humidity in the air, not the moisture content of the cedar. A high reading after a day or two may simply mean the air is humid while the wood is still absorbing moisture.
How to Know When a Humidor Is Seasoned
With the Boveda method, the simplest answer is to complete the full 14-day process rather than trying to judge readiness from an early hygrometer reading. Once the 14 days are complete, remove the seasoning packs and transition to normal storage humidity.
With a manual method, you need to pay more attention to how the humidor behaves after the temporary moisture source is removed. The RH should remain reasonably stable instead of collapsing immediately, the hygrometer should be giving believable readings, and there should be no visible wet wood or condensation. If humidity drops quickly, that does not automatically mean the whole seasoning process failed. A weak lid seal, frequent opening, an inaccurate hygrometer, or insufficient normal-storage humidification can all create the same symptom.
7 Humidor Seasoning Mistakes to Avoid
Putting Cigars in Before Seasoning Is Finished
Cigars should stay out of the humidor until the wood has finished conditioning. Dry cedar can draw moisture from the cigars themselves, which works against the purpose of the humidor. If you already have cigars, keep them in temporary storage until the box is ready.
Using Tap Water
If you are using a water-based method, distilled water is the better choice because it reduces the chance of leaving minerals or other impurities behind. Tap water adds unnecessary variables to an environment that will eventually be used for long-term cigar storage.
Soaking or Heavily Wiping the Wood
The cedar needs to absorb moisture gradually, not become visibly wet. Soaking or heavily wiping the interior can cause swelling, warping, veneer damage, or problems with the seal. Slow conditioning is safer than trying to speed up the process with more water.
Opening the Lid Repeatedly
Frequent checking lets humid air escape and replaces it with drier room air, which slows the conditioning process. Leave the humidor closed as much as possible, especially during the 14-day Boveda process.
Using 84% Seasoning Packs With Cigars Inside
Boveda 84% packs are intended for empty wooden humidors, not normal cigar storage. Once seasoning is complete, remove them and switch to standard maintenance humidity before adding cigars.
Mixing Different Boveda RH Levels
Do not mix B84 seasoning packs with lower-RH storage packs during seasoning. The purpose of this stage is to create one controlled environment for the wood. Once the box is conditioned, you can move to the RH level you prefer for normal storage.
Trusting an Uncalibrated Hygrometer
An inaccurate hygrometer can make a correctly seasoned humidor look too wet or too dry, which can lead to unnecessary re-seasoning or over-correction. Before changing the setup, make sure the gauge itself is reliable. If the humidor continues to struggle after seasoning, compare the reading with a dependable cigar hygrometer and check the seal before starting over.
How to Set Up a Humidor After Seasoning
Once the seasoning stage is complete, remove the seasoning materials and install the humidity control you plan to use for normal storage. Confirm that the hygrometer is working properly, then add your cigars and watch the environment more closely during the first several days while the humidor settles into regular use.
This new humidor setup stage is where the purpose of the box changes. During seasoning, you are conditioning the wood. Afterward, you are maintaining a stable environment for the cigars themselves. Normal cigar-storage humidity is lower than the 84% used during Boveda seasoning, so do not treat the seasoning RH as your long-term target. Lucky Cigar's guide on how to keep cigars fresh covers the longer-term storage side in more detail.
If you are learning how to set up a humidor or how to set up a cigar humidor, it is also worth giving the box a little time to settle after seasoning. Small RH changes during the first few days do not always mean something is wrong, especially as the cigars, wood, and humidification system adjust to one another.
Frequently Asked Questions About Seasoning a Humidor
Do all humidors need to be seasoned?
No. Traditional wooden humidors usually need conditioning because their unfinished interiors absorb moisture, but plastic and acrylic travel humidors do not behave the same way. Some electric humidors may still need conditioning if they contain unfinished wooden shelves, trays, or panels.
How often should you season a humidor?
A well-maintained humidor does not need to be re-seasoned every time you refill it. Consider re-seasoning if it has been left empty and dry for an extended period or if it consistently struggles to maintain humidity after you have checked the hygrometer, seal, and normal humidification system.
Can you use regular Boveda packs instead of 84% seasoning packs?
The 84% packs are made for conditioning empty wooden humidors, while normal storage packs are intended to maintain cigars after seasoning is complete. They serve different purposes, so regular storage packs should not automatically be treated as substitutes during the initial setup.
Why is my humidor humidity dropping after seasoning?
A falling RH reading can come from several different causes, including wood that is still absorbing moisture, a weak seal, frequent lid opening, an inaccurate hygrometer, or a normal-storage humidity source that is too small for the box. Check those factors before assuming the entire seasoning process needs to be repeated.
Can I store cigars somewhere else while seasoning a humidor?
Yes. Keep them in a sealed temporary container with appropriate humidity control until the humidor is ready. A travel humidor or suitable cigar case can work for short-term storage, depending on capacity and how long the seasoning process takes.
Season the Wood First, Then Store Your Cigars
A properly seasoned humidor gives you a much better starting point for long-term cigar storage. Whether you use the 14-day Boveda method or a traditional distilled-water approach, the goal is the same: condition the wood first so the humidor can hold a more stable environment once cigars are added.
Do not judge the process by one high RH reading. What matters is that the wood has had enough time to absorb moisture and the humidor can maintain normal storage conditions afterward. Once seasoning is complete, switch to your regular humidity control, confirm that the hygrometer is reading accurately, and give the box a little time to settle into everyday use.
From there, good storage becomes about consistency. Lucky Cigar offers cigar humidors, hygrometers, and other storage accessories that can help you build a setup that is easier to monitor and maintain over time.
