How to Season a New Wooden Humidor Step by Step
A dry new wooden humidor can pull moisture from your cigars before you notice the problem. This can lead to unstable cigar storage, falling humidity, and confusion about which part of the setup is driving the change.
The correct process depends on the moisture product. This guide separates Boveda B84 Size 60 seasoning packs from liquid humidifiers. A Boveda B84 cycle requires an empty wooden humidor to remain closed for 14 days, while a liquid device has no universal fill amount or timeline and must follow its own manufacturer's instructions. Do not combine the two methods.
In this guide, you will learn how to complete a safe humidor setup, choose the right method, avoid wetting the cedar, follow the correct timeline, and decide when the humidor is ready for cigars.
Before You Start: Why Humidor Seasoning Comes First
A new wooden humidor is not always ready for cigars as soon as you open the box. The inner wood needs time to take in moisture in a controlled way.
Why New Wood Needs Conditioning
Many wooden humidors use Spanish cedar inside. Cedar can absorb and release some moisture. This helps the humidor respond to small changes in room humidity.
If the wood is very dry, it may remove moisture from your cigars. This can make cigars feel dry and make the box harder to control.
Seasoning brings the wood closer to stable storage conditions. It does not guarantee perfect storage, but it reduces the risk of loading cigars into an unprepared box.
What Humidor Seasoning Does and Does Not Do
Humidor seasoning means conditioning the inner wood slowly. It does not mean soaking the cedar or forcing the RH to the highest possible number.
Do not season a humidor by:
- Pouring water into the box
- Spraying or wiping the cedar with water
- Leaving a soaked sponge inside
- Using several humidifiers at once
- Adding cigars before the process is complete
- Adding more moisture after every low reading
The aim is balanced moisture, not wet wood.
What a Seasoned Humidor Should Do
A ready humidor should meet the completion rule for the selected seasoning method and show no signs of excess moisture or damage.
Look for these signs:
- There is no condensation or standing water
- The cedar is not visibly wet
- The lid closes evenly
- The humidification source is not leaking
- The required method-specific seasoning cycle is complete
Do not treat one high RH reading as proof of completion. Use the completion rule for the selected method and check for excess moisture before adding cigars.
Prepare the Humidor, Hygrometer, and Room
Before you add any moisture, check the box, verify the hygrometer, and choose a steady place for the humidor setup.
Inspect the Humidor Before Adding Moisture
Remove plastic, stickers, packaging, and loose dust. If needed, use a clean, dry cloth.
Check the following points:
- Cracks or damaged wood
- Loose hinges or hardware
- Broken trays or dividers
- Wet spots or dark stains
- Strong or unusual odors
- A lid that does not close evenly
- Visible gaps around the lid
If the humidor arrives damaged, do not begin seasoning. Take clear photos and contact the seller or manufacturer first.
Check the humidor manufacturer's instructions before setup. They may specify the correct tray position, humidifier type, fill level, and care requirements.
Check the Hygrometer and Record a Baseline
You will usually need:
- The humidor
- A reliable hygrometer
- One method-specific seasoning product
- Clean, dry cloth
- A notebook or phone app
A hygrometer measures relative humidity. RH shows how much moisture is in the air compared with the amount the air can hold at that temperature.
Check or calibrate the hygrometer before you trust its reading. Keep it in the main storage area, away from direct liquid.
Before seasoning starts, record:
- Room temperature
- Room RH
- Humidor RH
- The date and time
For help with hygrometer types and placement, read How to Choose the Best Hygrometer for a Humidor.
Arrange the Interior and Choose a Stable Location
Follow the product instructions when deciding whether to leave trays and dividers inside. Wooden parts may also absorb moisture.
Arrange the parts so air can move around them. Do not block the hygrometer or place it directly beside a liquid humidifier.
Keep the humidor away from:
- Direct sunlight
- Heaters and radiators
- Air-conditioning vents
- Open windows
- Kitchens and bathrooms
- Strong drafts
- Paint, cleaners, and perfume
Location matters because rapid changes in room temperature or humidity can make RH readings difficult to interpret.
Choose the Right Humidor Seasoning Method
This guide covers two separate paths: a Boveda B84 Size 60 seasoning pack or a manufacturer-specified liquid humidifier. They are not interchangeable. Choose one documented method and do not combine it with another moisture source.
Choose one documented method and stay with it.
Boveda B84 uses a fixed 14-day closed-lid cycle. A liquid humidifier follows the exact device instructions for fill amount, placement, timing, monitoring, and completion.
When to Use Boveda B84 Seasoning Packs
Boveda B84 Size 60 is a purpose-made seasoning product for an empty wooden humidor. Use the number of packets specified by Boveda for the humidor's stated capacity on the current product packaging or instructions; do not guess or add extra packets.
Choose this method when:
- The humidor and Boveda instructions are compatible
- You know the humidor's stated capacity
- You can leave the humidor empty and closed for the full 14-day cycle
- You have the appropriate maintenance RH product ready for the transition after seasoning
Do not cut open the brown packets or add water to them. Remove only the clear outer overwrap when present.
When to Use a Liquid Humidifier
A liquid humidifier is a device-specific method, not a universal recipe. Use one only when the exact device instructions state that it is suitable for seasoning the humidor.
Before starting, the device manual must identify:
- The humidor capacity or device coverage
- The compatible liquid
- The exact fill amount or fill line
- Placement and contact restrictions
- Whether and when the lid may be opened
- The monitoring method and seasoning duration
- The completion standard
- Refill, disposal, and maintenance-transition instructions
If any of these details are missing, do not improvise a liquid amount or timeline. Ask the device manufacturer for instructions or use a fully documented alternative.
How to Avoid Incompatible Liquids
Do not place a liquid inside a humidifier unless the device manufacturer lists it.
Avoid:
- Tap water unless the device instructions allow it
- Alcohol
- Oils
- Perfume
- Cleaning products
- Homemade mixtures
- Wet sponges or cloths
Distilled water is not a universal substitute for seasoning solution. Use it only when the exact device instructions call for it.

Season the Humidor Step by Step
Follow only the method selected above. Do not combine a Boveda B84 seasoning pack with a liquid humidifier.
Boveda B84 Size 60 Seasoning Packs
- Confirm the humidor's rated capacity and use the number of B84 Size 60 packets specified by Boveda's current packaging or instructions.
- Empty the wooden humidor. Leave wooden shelves and trays inside when the product instructions call for them to remain.
- Remove the clear outer overwrap when present, but do not cut or open the brown packet.
- Place the packets inside the humidor. They may sit loose or in an official Boveda cedar holder; a blanket rule requiring Boveda packets to stay away from cedar does not apply.
- Close the lid and do not open the humidor for 14 days, regardless of the hygrometer reading.
- Ignore hygrometer readings during the 14-day B84 seasoning cycle. Do not add liquid or another humidity product.
- After 14 full days, open the humidor, remove the B84 seasoning packets, and discard them because they are not reusable.
- Add cigars and install the preferred Boveda maintenance RH packets according to their current quantity and replacement instructions.
For this method, the full 14-day closed-lid cycle is the completion rule. A 24- or 48-hour RH reading is not a completion checkpoint.
A Manufacturer-Specified Liquid Humidifier
- Identify the exact humidifier and confirm that its manufacturer permits it to be used for seasoning.
- Match the device's stated coverage to the humidor capacity.
- Use only the liquid and fill amount or fill line listed for that device.
- Follow the manual's placement and contact rules. Keep liquid contained inside the device and stop if it leaks into the wood.
- Follow the manual's lid-opening, monitoring, and timing instructions; do not apply the Boveda 14-day rule or a generic 24- or 48-hour schedule to a liquid device.
- Use the manual's completion standard. If it does not provide one, contact the manufacturer rather than inventing an RH threshold or duration.
- Follow the same manual for refill or disposal and for the transition from seasoning to regular maintenance.
Do not begin this method without the exact device instructions. There is no universal liquid, fill amount, opening schedule, or finish point that applies to every liquid humidifier.
Avoid Common Humidor Seasoning Mistakes
Most seasoning problems come from too much moisture or too many quick adjustments.
Do Not Wet the Cedar Directly
Do not pour water onto the cedar. Do not spray it, soak it, or wipe it with a very wet cloth.
Direct liquid can cause:
- Water stains
- Uneven absorption
- Swollen wood
- Lid-fit problems
- Unstable RH control
Use the documented humidification method instead. Let the moisture in the closed air condition the wood slowly.
Do Not Chase a High RH Reading
A fast rise in RH does not prove that seasoning is complete. The air may become humid before the wood has adjusted evenly.
Follow the completion rule for the selected method rather than reacting to the highest number.
If you see condensation, wet cedar, or liquid, stop adding moisture and inspect the setup.
Many cigar-storage systems operate around 65%-70% RH. This is a common range, not a rule for every cigar, humidor, or storage method.
For long-term guidance, read How to Maintain the Perfect Humidity in Your Cigar Humidor.
Do Not Add Moisture Too Quickly
During a Boveda B84 cycle, do not open the humidor or add another moisture source during the required 14 days. With a liquid device, make adjustments only as its instructions direct.
Common mistakes include:
- Using more packs than instructed
- Combining a pack with a liquid humidifier
- Refilling after one low reading
- Switching products too quickly
- Opening the lid more often than the selected method allows
- Testing the box with cigars before the method-specific cycle is complete
Change only one permitted variable at a time, then give the humidor time to respond.
When Humidor RH Does Not Rise as Expected
Do not use this troubleshooting section to interrupt a Boveda B84 14-day closed-lid cycle. Use it after that cycle or when the liquid-device instructions tell you to monitor RH during seasoning.
A low RH reading does not always mean that the humidor needs more moisture. Check the measurement first, then inspect the box and the environment.
Check the Hygrometer First
Before adding anything, confirm that the reading is reliable.
Check:
- The battery, if the unit uses one
- Whether the hygrometer has been calibrated
- Whether it is too close to the moisture source
- Whether it touches the wall or lid
- Whether room temperature has changed
- Whether a second hygrometer shows a similar reading
Do not add more moisture until you trust the reading and the selected method permits an adjustment.
Check the Seal, Room, and Moisture Source
If the hygrometer seems reliable, inspect the physical setup.
Look for:
- A lid that does not close evenly
- Visible gaps
- Frequent opening
- Heat or direct airflow
- A dry or damaged pack
- An unsuitable humidifier
- A leaking humidifier
- Blocked airflow around trays
- A sudden room temperature change
Correct one permitted issue at a time. Then wait and record the result.
Know When to Stop and Ask for Help
Stop adding moisture if you see:
- Condensation
- Standing liquid
- Wet cedar
- Swollen wood
- A suddenly tight lid
- A leaking humidifier
- Mold
- A musty smell
- Sharp unexplained RH changes
Remove a leaking or incompatible moisture source when it is safe to do so. Do not add cigars until the problem is resolved.
Mold is not a normal part of seasoning. Treat it as a separate problem.
For more information, read Mold in Humidor: How to Identify, Prevent, and Remove It.
When RH seems wrong, verify the hygrometer, inspect the seal and environment, and then check the moisture source according to its instructions. If you find excess moisture, mold, or damage, stop and seek product-specific help before continuing.
How to Know When Humidor Seasoning Is Complete
Completion depends on the selected method. Do not replace a product-specific endpoint with a generic RH reading.
Confirm the Method-Specific Endpoint
For Boveda B84 Size 60 seasoning packs:
- Complete the full 14-day cycle with the empty humidor closed
- Ignore hygrometer readings during those 14 days
- Remove and discard the seasoning packets after the cycle
- Switch to the chosen Boveda maintenance RH packets
For a liquid humidifier:
- Use the exact duration and completion standard in the device instructions
- Use a checked or calibrated hygrometer if the instructions require RH monitoring
- Do not invent a target, stability period, or finish point when the manual does not provide one
Check for Excess Moisture and Odors
Look inside the humidor before loading cigars.
You should not see:
- Condensation
- Standing water
- Wet cedar
- Dark water stains
- Swollen wood
- Mold
- Liquid around the humidifier
You should also not notice a strong musty smell.
If the interior looks wet, do not add cigars. Remove the cause of excess moisture when it is safe to do so and allow the humidor to settle.
Use the Final Humidor Readiness Checklist
Before loading cigars, confirm:
- You used only one documented seasoning method
- The method-specific cycle is complete
- Boveda B84 seasoning packets have been removed and discarded, or the liquid-device instructions have been completed
- The cedar is not visibly wet
- There is no condensation, standing water, mold, musty smell, or leak
- The lid closes evenly
- You have the correct maintenance product and instructions ready
If one important item is incomplete, wait before adding cigars.
Add Cigars and Switch to Humidor Maintenance
After the readiness check, your goal changes. You are no longer conditioning the wood. You are maintaining stable storage conditions.
Add Cigars in Small Batches
If possible, add cigars gradually instead of filling the humidor on the first day.
Leave space for air to move. Do not block the humidifier or pack the cigars tightly.
The RH may change after you add cigars. Watch the trend before making adjustments. A short-term drop does not always mean that the setup has failed.
Switch From Seasoning to Regular Maintenance
Initial seasoning prepares the wood. Regular humidor maintenance keeps the conditions stable afterward.
For normal use:
- After a Boveda B84 cycle, discard the seasoning packets and install the preferred Boveda maintenance RH packets according to their instructions
- For a liquid device, follow its refill, replacement, and maintenance-transition instructions
- Keep liquid inside the compatible device
- Do not restart full seasoning after every small RH change
- Leave space for airflow
Follow the humidor or humidifier manufacturer's maintenance instructions. A product made for initial seasoning is not always suitable for long-term storage.
Monitor the First Week After Loading
Check the hygrometer about once a day during the first week unless the maintenance product instructions specify otherwise.
During this period:
- Avoid unnecessary lid opening
- Do not overfill the box
- Keep the humidor in the same room
- Watch for sudden RH changes
- Check for condensation or wet wood
- Change only one permitted variable at a time
If RH remains reasonably stable, continue normal maintenance. If it stays low or changes sharply, return to the checks for the hygrometer, lid seal, room, and humidifier.

Frequently Asked Questions
How long does it take to season a new humidor?
It depends on the method. Boveda B84 Size 60 seasoning packs require a full 14-day closed-lid cycle. Liquid humidifiers should follow the exact timeline provided by the manufacturer.
Can I put cigars in the humidor while seasoning it?
No. Keep the humidor empty until the selected seasoning process is complete and there are no signs of excess moisture, leaks, mold, or wet cedar.
Should I wipe the cedar with water before seasoning?
No. Do not spray, soak, or wipe the cedar with water. Direct moisture can cause stains, swelling, uneven absorption, and lid-fit problems.
Can I use Boveda seasoning packs and a liquid humidifier together?
No. Use only one documented seasoning method at a time. Combining moisture sources can make humidity harder to control and may introduce too much moisture.
What RH should a seasoned humidor reach?
There is no single RH number that proves seasoning is complete. Follow the completion rule for your chosen method instead of relying on one hygrometer reading.
Final Takeaway
Humidor seasoning is product-specific. If you use Boveda B84 Size 60 seasoning packs, use the quantity Boveda specifies for the humidor's capacity, keep the empty humidor closed for 14 days without checking the hygrometer, then remove and discard the seasoning packets before installing maintenance RH packs. If you use a liquid humidifier, follow its exact instructions for capacity, liquid, fill amount, placement, lid opening, monitoring, duration, completion, and maintenance; do not improvise missing details.
With either method, never pour liquid onto the cedar or combine moisture sources. Complete the selected method and confirm that there is no excess moisture, mold, leak, or damage before adding cigars.
Start by matching the humidor and moisture source to the manufacturer's instructions. Use one documented method and complete it before adding cigars.
