Field notes from maintenance practice
The classic '70/70' (70% RH, 70 °F) is a starting point many now nudge drier to 65% for a firmer draw and lower mould risk. Stability and avoiding the >72% mould zone matter most — watch the maximum, season your humidor properly before first use, and use a calibrated hygrometer (the cheap analog ones lie by 5–10%). Cigars are unforgiving of both extremes: too dry and the wrapper cracks and the smoke turns harsh, too humid and they won't draw and mould appears — and a big humidor opened often, or seasonal swings, makes holding the band harder than it looks.
Consistency makes the numbers meaningful: measure at the same point, with the same instrument, at sensible intervals (continuous where the risk is high, spot-checks where it is low). The in-range percentage is the metric to watch — a band that quietly drifts from 100% toward 95% is telling you something is changing before any single reading alarms.

About Cigar Humidor Humidity Dashboard
This dashboard turns scattered relative humidity checks for a cigar humidor into a monitored series: log a reading whenever you measure and it tracks the latest value, the average, the min/max range, the percentage of readings inside the acceptable band and the number of excursions — the everyday telemetry picture, computed in your browser with no logger subscription. The default acceptable band is 65–72% RH (the '69% / 70%' rule), often paired with ~18 °C.

Frequently asked questions
What is the acceptable relative humidity range for a cigar humidor?+
The default band is 65–72% RH (the '69% / 70%' rule), often paired with ~18 °C. Treat it as a sensible starting point — your own specification, regulator, equipment manual or product datasheet sets the authoritative limits, and you can read your true band straight off the worst case those documents allow. Edit the readings against whatever band applies to you.
65% or 70% RH — and how do I avoid mould?+
Both work; the trend is toward 65% for a better draw and a wider safety margin below the mould zone, while 70% keeps cigars a touch more supple. Stay under ~72% RH and you'll avoid mould (which appears as fuzzy white/green growth — distinct from harmless white 'plume' crystals). Keep temperature moderate (warmth plus moisture is what breeds mould and tobacco beetles), season the humidor's wood before loading, use a quality humidification source, and calibrate your hygrometer with the salt test so the number you trust is real.
How often should I log relative humidity readings?+
Match the interval to the consequence and the rate of change: where an excursion spoils product or risks safety, log continuously (or as often as you can sample); where it is merely informative, daily or per-shift spot checks suffice. The in-range % and excursion count only mean something if your sampling is regular — sparse, irregular readings hide the excursions between them.
Is my logged data private?+
Yes — every reading is stored in this browser's localStorage on your device and nothing is uploaded to any server, which also makes the dashboard usable on sites with strict data policies. For shared, audit-grade records across a team or for regulatory retention, export the values into your own system.
