Your Onyx seasons with Klaro Humidor Solution through its two hydro channels — a refillable system that holds humidity beautifully once it's charged. Give it a little time to come up to temperature and humidity, and it'll hold your collection right where it should be.

Important Notes

• Keep your Onyx as close to 70°F as possible. Lower temperatures slow the solution's evaporation; higher temperatures dry the humidor out quickly.
• Never place the humidor in direct sunlight — it rapidly lowers humidity.
• Winter months and dry climates need a little more diligence. Adding distilled water alongside the Humidor Solution — or switching to Winter Solution — boosts humidity faster than solution alone.
• We don't recommend Boveda packs. We've tested them extensively in our solution humidors with poor results — the two-channel hydro system is what keeps the Onyx stable.

Seasoning Your Onyx

1. Remove the lids from both Hydro Channels and set them aside.
2. Tear open the included Gel Solution packet and evenly distribute the gel crystals across the sections of each of the two Hydro Channel bases.
3. Slowly pour Klaro Humidor Solution over the crystals until they're fully saturated — while seasoning, use the Winter + Dry Climate Solution for an extra boost. Allow 6–12 hours for the gel to fully absorb the solution. Out of gel or solution? The Klaro Membership ships a year's supply of Humidor Solution, Winter Solution, and Gel Solution — plus a fresh hygrometer battery.
4. Place both charged Hydro Channel bases in the bottom of the humidor and set their lids back on.
5. Let the humidor rest until the reading holds above 68% for 1–3 consecutive days. Depending on your climate, this can take up to two weeks. Slow to climb? Lightly dampen a paper towel with solution and gently wipe the inside cedar lining to boost humidity.
6. Check your humidity and fine-tune:
   • 70–75% — you're set; no more solution needed.
   • 65–69% — add a little more Winter + Dry Climate Solution.
   • Above 75% — remove one Hydro Channel for 24–48 hours, then re-check.
7. Once it holds in the 67–75% range, add your cigars. With cigars stored inside, the optimal range is 65–72%.

In milder climates you can run a single Hydro Channel and store the second for drier seasons. After seasoning, rotate your cigars biweekly and refill the channels periodically.

Calibration

Your Onyx ships pre-calibrated from the factory, so in almost every case you'll never need to touch this. Do not recalibrate unless you're certain it's needed.

If you do need to recalibrate:

1. Let the humidor stabilize and confirm it's truly reading 70% on a trusted reference hygrometer.
2. Press and hold the touch-sensitive area on the front fabric for about 5 seconds.
3. The on-unit reading will snap to 70%, setting your new calibration baseline.

Getting the Most From Your Onyx With the Klaro App

Your Onyx comes with the Klaro app built in, and it ships with a bridge — so you can check on your humidor's humidity and temperature from anywhere, anytime, right from your phone.

• Monitor from anywhere. The included bridge keeps your Onyx connected, so live humidity and temperature are always a glance away — even when you're away from home.
• Keep a journal. Log your collection and track conditions over time with the newly updated in-app Journal.
• Control your lighting. Adjust the LED lighting from your phone with far more freedom than the on-board button.

Using Your On-Board LED Button

Prefer to set your lighting right on the unit? The on-board button handles it — no phone needed.

• Brightness & off: a quick press steps through the brightness levels and then turns the light off.
• Change the color: press and hold for about 3 seconds — the light flashes three times, then begins cycling through the colors. When it lands on a color you like, take your finger off; the light blinks three times to confirm your selection.

How the Proximity Sensor Works

Out of the box, your Onyx uses motion sensing to trigger both the LED lighting and the front digital hygrometer — they wake as you approach and fade out after a stretch with no motion, so the unit sits dark and discreet at rest.

You can set the LEDs to stay always on or always off if you prefer. The front hygrometer stays motion-triggered — that behavior is fixed: it lights up when it senses you and fades again once the room is still.
