Dry Herb Vaporizer Temperature Guide: What Temperature Should You Vape At?

Every review on this site tells you to start at 180°C, and every one of them gets a follow-up asking why. This is the longer answer, with a chart, the chemistry behind it, and the right starting setting for each device we sell, including the ones where the control is a numbered dial or a coloured LED rather than a figure on a screen.

The short answer is to start at 180°C

180°C is the preset the Crafty+ and the Veazy ship with, it's the temperature every review on this site starts at, and it's where the flavour of the herb is still clearly there while the vapour has enough body to feel like something. It also sits comfortably below the point where plant material starts to scorch, so a few degrees either way does no harm.

If you only ever use one number, 180°C is a good one. If you're prepared to press the up button two or three times during a session, you'll get more out of every bowl, and the rest of this guide explains how.

What changing the temperature actually does

A dry herb vaporizer heats the herb to a point where the active compounds and the aromatic oils evaporate, without the plant material itself burning. Combustion needs roughly 230°C and above, which is why the Storz & Bickel portables stop at 210°C and most of the XMax and Arizer portables at 220°C. Everything you do with the temperature control happens in the window between about 160°C and that ceiling.

At the low end, around 160°C to 175°C, only the most volatile compounds are coming off the herb, so each draw carries less, the vapour is thin and sometimes barely visible, and the flavour is at its brightest. As you climb towards 200°C more compounds evaporate with every draw, the vapour gets denser and warmer on the throat, and the flavour shifts from fresh to toasted. Above 210°C you're pulling the last of what's in the bowl, the vapour is at its thickest and harshest, and the taste moves towards burnt popcorn. None of those stages is wrong. They're just different jobs, and the chart below sets them out.

Dry herb vaporizer temperature chart

Two things to keep in mind when reading it. The temperature on the screen is the setting rather than a measurement of the herb, and the two can differ by ten degrees or more depending on the device, which the section on why devices differ covers. And thin-looking vapour at 175°C isn't empty. It's carrying less per draw than a 205°C cloud, but it's carrying the part of the herb that tastes best.

Cannabinoid and terpene boiling points

The reason temperature changes flavour is that the compounds in the herb evaporate at different points. The figures below are the published boiling points, taken from PubChem and the McPartland and Russo review that the common terpene charts are built on. They explain the order things arrive in rather than giving you a switch for each one, because compounds start to evaporate well below their boiling point and carry on above it.

Read down the table and you can see why a bowl changes character as it warms. The peppery and piney notes and the first of the cannabinoids come off in the 150s and 160s, citrus arrives in the 170s, and the heavier floral notes need close to 200°C. A 2016 laboratory study in PLOS ONE (Lanz and colleagues, University of Bern) found that electrically heated, temperature-controlled vaporizers run at 210°C converted at least 97% of the acidic THC in the herb into its active form and released it reliably into the vapour, which is the practical case for finishing a bowl hot. The same study measured slightly more CBN, a breakdown product of THC, in the vapour than in the raw herb, which is the practical case for not living at the top of the range.

Why stepping up through a session works

Because the lighter compounds leave first, a bowl that's been run at 180°C for a few minutes still has most of its heavier compounds in it. Turn the temperature up and they come off too. Run the whole bowl at 210°C from the start and you get everything at once, in one harsh rush, with the flavour already toasted on the first draw. Stepping up gives you the flavour at the beginning, the body in the middle and a clean, finished bowl at the end.

The routine that works on every device we stock is to start at 180°C, take three or four slow draws, then go up by 5°C to 10°C and repeat, finishing somewhere between 205°C and 215°C when the vapour thins out and the taste turns to popcorn. On a conduction device, stir the bowl once about halfway through. On the Storz & Bickel portables you don't need to press the up button at all, because that's what Boost is for. On the Venty and the Mighty+, a double click adds 15°C for about 90 seconds and a second double click adds another 15°C, so a session set at 180°C steps to 195°C and then 210°C with two presses and drops back on its own.

The starting setting for every device we stock

Not every device gives you a number. The TinyMight 2 has a dial from 1 to 10, the Anix Pluto has three colours, the Volcano Classic has a dial from 1 to 9, and the XMax V3 Nano has no control at all. The table gives the control each device has, its range, and the setting we'd start on. Prices are correct at 14 October 2026.

 

If your device isn't in the table, the rule still holds. Start at 180°C or the nearest preset, and if the only control is a dial, start in the middle of it.

Why two devices at 180°C don't feel the same

Set an Anix Pluto, an XMax V4 Pro and a Venty to the same temperature and you'll get three different draws, which confuses a lot of people who've just upgraded. Four things cause it.

The first is how the heat reaches the herb. A conduction device heats the chamber wall, so the herb touching the wall is at the set temperature and the herb in the middle is cooler until you stir. A convection device heats air and pulls it through the whole load, so the herb cooks more evenly and tastes cleaner at the same number. That's why the Pluto's presets start at 200°C while the V4 Pro's sweet spot is 180°C, and it's the whole subject of our conduction vs convection guide.

The second is the sensor. Every device measures temperature somewhere near the heater rather than in the herb, so the display is always a little ahead of the bowl, and more so on a tightly packed conduction chamber. The third is your draw. On a convection device a fast, hard pull drags air past the heater before it's hot, so the vapour thins out and you reach for a higher setting you don't need, when a slow five-second draw at the same number would have been dense. And the fourth is how long the device has been on. The first bowl straight after heat-up is cooler than the second, because the chamber housing hasn't warmed through, which is why some owners find 180°C perfect on bowl two and a bit thin on bowl one.

Five mistakes that make any temperature feel wrong

1. Starting at the top. 210°C from cold gives you the harshest draw of the session first and nothing to step up to. Start at 180°C and climb.
2. Drawing too fast. The single biggest cause of thin vapour on a convection device. Slow down before you turn it up.
3. Packing tight. On a conduction device a packed chamber cooks on the outside and stays raw in the middle. Fill loosely, stir once.
4. Never cleaning the screens. A clogged screen or cooling unit restricts airflow, which feels exactly like the device running cool. If 180°C has started to feel weak on a device that used to be fine, clean it before changing anything else.
5. Judging by the cloud. Dense vapour tells you the temperature is high; it doesn't tell you the session is better. If the taste has gone to popcorn and your throat is catching, you've passed the useful part of the bowl, however impressive it looks.

FAQs

What is the best temperature for a dry herb vaporizer?

180°C to start, then 185°C to 200°C for most of the session, finishing at 205°C to 215°C. Lower for flavour, higher for dense vapour. The chart above sets out each band.

What temperature does dry herb burn at?

Plant material starts to char at roughly 230°C, which is why Storz & Bickel cap their portables at 210°C and the Volcano at 230°C, and why XMax and Arizer portables stop at 220°C. Devices that go higher, such as the XMax Ace and Nectar Gold 2.0 Plus at 240°C, give you a margin you'll rarely use.

Is a lower temperature better for flavour?

Yes. The compounds that carry the pine, pepper and citrus notes evaporate between about 130°C and 176°C, so the first draws at 170°C to 180°C are the most flavourful of the whole bowl. Everything above 200°C tastes toasted.

What temperature should I use for the Volcano?

185°C for a first balloon on the Volcano Hybrid, then 200°C and 215°C for the second and third from the same bowl. On the Volcano Classic that's dial position 5, then 6 and 7.

Why is my vapour harsh?

In order of likelihood: the temperature is above 200°C, you're drawing too hard, or the screen and cooling unit need a clean. Running through water fixes the first two, and a 20-minute soak in isopropyl alcohol fixes the third. If the harshness arrived with a new bag of herb, it may also simply be drier than the last one.
