Boveda, beads or a sponge: what each one fails at
All three hold humidity. They fail in different directions, and that is how you choose.
Two-way packs for most people, beads if you want control, a sponge only in an emergency. The differences are not about accuracy — all three can hold a number — but about what happens when conditions change.
Two-way packs
Sealed packs of salt solution both release and absorb moisture, holding a fixed level with no attention at all. They are the right default: no maintenance, no overshoot, no distilled water on the shelf.
Where they fail: they run out, and they do it quietly. A hardened pack is doing nothing while the hygrometer slowly drifts. They are also the most expensive option per year, and they cannot be adjusted — a 69 pack is a 69 pack.
Silica beads
Beads are tuned to a target and, like packs, work in both directions. They are refillable, cheap over years, and you can see the state at a glance: dry beads go clear or change colour depending on the type.
Where they fail: they need distilled water, they need refilling by hand, and it is easy to overshoot right after a refill. They are the option for someone who enjoys the ritual and checks the box weekly, not for someone who wants to forget about it.
The foam sponge in old humidors
The green foam unit glued inside cheap humidors only adds moisture; it cannot take any back. That is the whole problem: it drives humidity up to whatever the foam is soaked to, usually far past 75 per cent, and then the box has no way down except through the wood.
If a humidor came with one, take it out and replace it with a pack. Nothing about the foam is worth defending, and propylene glycol solutions only make the ceiling more stubborn.
Do this: whatever you use, write the date you installed or refilled it on the packaging with a marker. Humidification fails gradually, and a date is the only way to catch it before the wrappers do.
Sizing, which is where most setups go wrong
One small pack in a large cabinet cannot hold a level, and people conclude their humidor leaks when it is simply under-provisioned. Match the capacity to the volume — most manufacturers publish a table — and round up rather than down.
Equally: a full humidor needs less humidification than an empty one, because the cigars and cedar themselves act as a reservoir. A box you keep half empty will always be harder to hold steady than the same box packed.
What the app tracks is the other half
Humidification is hardware and Ligero does not touch it — there is no sensor, no reading, no humidity field. What it keeps is the inventory: which lots are in which humidor, when they arrived, what has rested long enough, and what has been sitting for two years. Nothing about that depends on remembering when you last refilled anything.
