Humidor

Humidor is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Humidor rather than just read about it. In short: A humidor is a humidity-controlled box or room used primarily for storing cigars, cigarettes, cannabis, or pipe tobacco. Either too much or too little humidity can be harmful to tobacco products; a humidor's primary function is to maintain a steady, desirable moisture level inside; secondarily it protects its contents from physical damage and deterioration from sunlight.

Key takeaways

  • Humidor belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Humidor to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Humidor from memory before moving on to harder problems.

Reference excerpt

A humidor is a humidity-controlled box or room used primarily for storing cigars, cigarettes, cannabis, or pipe tobacco. Either too much or too little humidity can be harmful to tobacco products; a humidor's primary function is to maintain a steady, desirable moisture level inside; secondarily it protects its contents from physical damage and deterioration from sunlight. For private use, small wooden boxes holding a few dozen or fewer cigars are common, while cigar shops may have walk-in humidors. Many humidors use hygrometers to monitor their humidity levels. When used and maintained properly, humidors can keep cigars fresh and in perfect condition for decades. Another use for a humidor is controlling the moisture level in a baseball, which can have a pronounced effect on its response when hit with a baseball bat. This phenomenon was so great that in order to put an end to much controversy, in 2002, nine years after joining the league, the Colorado Rockies started storing their game balls in a large walk-in humidor at their home stadium, thus counteracting the effects of the low humidity due mainly to Denver's famous mile-high altitude of around 5,280 feet above sea level. After the change, various offensive and defensive statistics at Rockies home games, especially the number of home runs, were found to be more in line with the rest of the league. In 2018 the Arizona Diamondbacks, whose Phoenix home field is affected by the arid Sonoran Desert climate, became the second Major League Baseball team to use a humidor.

Types

Walk-in Most common in cigar bars or stores. One room is built as or converted to a humidor where all the cigars are stored.

Cabinet Usually placed on the floor as a piece of furniture. It typically holds 1000–5000 cigars. A cabinet humidor is considered a good option for deep storage.

Desktop The most common type of humidor. Typically box sized with lid on top or with one or more drawers. Vary in size from 25–500 cigars capacity. Zino Davidoff is credited as the inventor of the desktop humidor.

Travel Portable, usually holding 2 to 20 cigars. Travel humidors must be especially durable and stand up to repeated openings.

Cannabis Typically box sized that maintains 62% humidity level.

Electric Similar to cabinet humidors, these are fully electronically controlled humidors and function similarly to a fridge. These models are generally the most expensive options on the market and come equipped with automated temperature and humidity control. Many models also come ready with LED display lights and touchscreen controls.

Construction Commercially made humidor cases are typically made of wood, although materials such as acrylic, glass, and metal are also used. Carbon fibre, silicon carbide, and polyethylene are rare. Aside from pleasing aesthetics, the casing's purpose is to protect the interior and create a closed environment, so any durable and airtight material can be used. The interior is typically a veneer of Spanish cedar, a traditional material which possesses several desirable characteristics for cigar storage:

It holds more moisture than most woods, so it helps maintain humidity. It is not prone to warping or cupping in high humidity. It imparts its aroma to cigars. For the same reason, some cigars are wrapped in Spanish-cedar sheets before they are sold. It can repel tobacco beetles, pinhead-sized pests which can ruin entire stocks of cigars by eating the tobacco and laying eggs, causing further infestation. They can also be discouraged by ensuring the humidor does not get hotter than 20 °C (68 °F). The beetle eggs usually only hatch at around 25 °C (77 °F), although there are also instances where they will hatch at cooler temperatures if the humidity is too high. Humidors are typically commercially produced, though most walk-ins are custom built and some humidors are homemade. They range considerably in material, size and complexity. Capacity is determined by deducting the space required for the humidification element and some extra room between the element and the cigars. It can also be calculated online for the most popular cigar formats using a humidor calculator based on a database of the most common cigars.

Maintenance A humidor needs to be seasoned when new or having been out of use for a while. Wood in an unseasoned humidor will absorb moisture from within, drying stored cigars out. The preferred technique for bringing the wood close to an optimal relative humidity level where it will buffer moisture is placing a small container of distilled water inside the humidor for 1 to 3 days.

Worked examples

Example 1 — a first encounter with Humidor

Start with the simplest possible case. Write down what Humidor claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Humidor before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Humidor ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Humidor

In research
Humidor appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Humidor in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Humidor is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cigars, Containers, Psychrometrics, so understanding it makes those chapters shorter.
In everyday life
Look for Humidor outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Why does Humidor matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Humidor?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
