Vaporiser Temperature Guide: The Complete Science of Vaping Temperatures

Temperature is the single most important variable in your vaping experience. Set it too low and you get flavourful but thin vapour. Crank it too high and you get thick clouds but lose the delicate terpenes that make each strain unique. But what is actually happening at each temperature?

Every compound in cannabis has a specific boiling point — the temperature at which it turns from a solid or liquid into a vapour you can inhale. Terpenes (aroma compounds) boil at lower temperatures. Cannabinoids (THC, CBD, etc.) boil at higher temperatures. By choosing your temperature strategically, you can target exactly which compounds you want to inhale at each stage of your session.

Complete Terpene Boiling Point Chart

Terpenes are the aromatic compounds that give cannabis strains their distinctive smells and contribute to the overall effect through the entourage effect. Each terpene has a different boiling point, which means you can selectively vaporise specific terpenes by adjusting your temperature.

Cannabinoid Vaporisation Temperatures

Cannabinoids are the active compounds responsible for the psychoactive and therapeutic effects of cannabis. Unlike terpenes, cannabinoids typically require higher temperatures to vaporise, and some need to be decarboxylated first — a chemical reaction where heat converts inactive acidic forms (THCa, CBDa) into their active forms (THC, CBD).

This is why vaping differs from eating raw cannabis. Eating THCa does nothing psychoactive — it must be heated (decarboxylated) to convert to THC. Vaporisers handle this conversion automatically during the warm-up phase, which is why the first few draws at lower temperatures still produce psychoactive effects.

Temperature-Strain Matching

Different cannabis strains have different dominant terpene profiles, which means the ideal vaping temperature changes depending on what you are smoking. Here is how to match your temperature to your strain:

Convection vs Conduction vs Hybrid: What the Temperature Actually Means

The type of heating in your vaporiser affects how the set temperature relates to the actual temperature of your herb. This is a common source of confusion for new vapers.

Convection vapes (Volcano Hybrid, Mighty+, Arizer Solo 3) heat air that passes through the herb. The chamber temperature closely matches the temperature of the air passing over your herb, so the set temperature is accurate. Start at 175°C and work up in 5-10°C increments. Because hot air transfers heat less efficiently than direct contact, convection vapes need longer draws (8-12 seconds) for optimal extraction.

Conduction vapes (PAX Plus, DaVinci IQ2) heat the chamber walls directly, which then heat your herb through contact. The chamber wall temperature is accurate, but the herb in the centre of the chamber can be 5-10°C cooler than the walls. Start at 185°C (10°C higher than you would with a convection vape) and stir the bowl mid-session for even extraction. Conduction vapes typically need shorter draws (4-6 seconds) because heat transfer is more direct.

Hybrid vapes (Venty, Mighty+) combine both heating methods — conduction heats the chamber while convection carries heat through the herb. This is the most efficient approach, as the herb receives heat from all directions simultaneously. Start at 175°C for flavour, finish at 200°C+ for full extraction. Hybrid vapes typically offer the best balance of flavour and vapour density across all temperature ranges.

Temperature Stepping: The Optimal Session Strategy

Rather than choosing a single temperature and sticking with it through the entire session, temperature stepping — gradually increasing the temperature over the course of a session — gives you the widest range of effects and the most efficient extraction from your herb.

Here is the ideal temperature stepping pattern based on our testing:

1. Draw 1-2: 170°C — Pure terpene hit. You will taste the strain's full aromatic profile with minimal vapour. This is the connoisseur phase. Savour it because you only get one shot at the light terpenes.
2. Draw 3-5: 180°C — THC boiling point is well past (157°C), so you start getting visible vapour with balanced psychoactive effects. Myrcene (168°C) and pinene (155°C) are still present, giving a flavourful-but-effective middle zone.
3. Draw 6-8: 195°C — Limonene (176°C) and CBD (180°C) are fully vaporising. The effects shift from cerebral to more full-body. Vapour density increases noticeably.
4. Draw 9-10: 205-210°C — Final extraction. Linalool (198°C), humulene (198°C), and CBN (185°C) are fully released. The vapour is thick, the flavour is cooked, and the effects are heavily sedating. Stop here to avoid combustion.

This four-stage approach extracts the full spectrum of compounds from your herb, giving you a considerably more nuanced experience than parking at a single temperature for the entire session.

The Science Behind the 230°C Limit

Most vaporisers cap their maximum temperature at 210-221°C. This is not arbitrary — it is the temperature at which dry plant matter begins to undergo pyrolysis (thermal decomposition without oxygen). The combustion point of dry cannabis flower is approximately 230°C. Below this threshold, you are vaporising (boiling off) active compounds. Above it, you are combusting (burning) plant material.

Combustion produces hundreds of additional chemical byproducts, including benzene, toluene, and naphthalene — compounds associated with the health risks of smoking. The entire purpose of vaping is to stay below this threshold while still effectively releasing the desired cannabinoids and terpenes. This is why setting your vaporiser above 210°C offers diminishing returns: you gain negligible additional cannabinoid extraction while approaching the combustion point.

Pro Tips for Better Sessions

• Start low, end high: Begin at 170°C and increase by 10°C increments every few draws. This is called temperature stepping and it extracts the widest range of compounds from your herb.
• Grind matters: A fluffy grind from a Santa Cruz Shredder increases surface area for more even vaporisation. A coarse grind suits convection vapes (better airflow), while a medium-fine grind suits conduction vapes (better contact with chamber walls).
• Pack loosely: Overpacking restricts airflow and creates uneven heating. Fill the chamber loosely — about 80% full — for optimal convection and even heat distribution.
• Clean regularly: Resin build-up in the cooling unit affects airflow and flavour. A dirty vape can run 5-10°C hotter than its set temperature because restricted airflow changes the heat dynamics. Clean your vape every 1-2 weeks.
• Draw speed: Slower draws (4-6 seconds) work better for conduction vapes. Faster draws (8-12 seconds) are better for convection vapes. Your draw speed directly affects the temperature inside the chamber — too fast cools the chamber, too slow can overheat it.
