For most dry cannabis flower, start between 175°C and 190°C (347°F to 374°F). Go lower, around 160°C to 175°C, for flavour and a lighter effect. Go higher, 195°C to 210°C, for thick vapour and a heavier, more sedating session. Stay under about 210°C so you’re vaporizing the flower and not burning it. That’s the short answer, and the rest of this guide shows you how to pick the exact number for your flower, your device and your mood.
TL; DR
- Meilleur point de départ : 180°C (356°F) for most flower. It’s a balanced middle that works on almost every device.
- Lower (160°C to 177°C): better flavour, lighter and clearer effects, thinner vapour.
- Higher (199°C to 210°C): denser vapour, heavier effects, harsher taste, faster loss of cannabinoids.
- Step up during one session: start low, then raise the temperature in small jumps to get more out of the same bowl.
- Your device matters: displayed temperatures aren’t identical from one vape to the next, so adjust by taste and vapour, not just the number.

Why temperature matters when you vape flower
A dry herb vaporizer heats flower until the active compounds turn to vapour, without setting the plant material on fire. Cannabinoids and terpenes each vaporize at different temperatures, so the setting you pick changes what ends up in the vapour. A guide from a Canadian cannabis accessory brand puts it simply: different compounds have different boiling points, so the makeup of the vapour shifts with the temperature you choose.
In practice that means three things you can feel:
- Saveur. Terpenes are the aromatic compounds that give flower its citrus, pine, earthy or floral character. Many of them vaporize at lower temperatures, so low settings taste the most like the flower smells.
- Vapour density. Higher heat pulls more out of the plant per draw, so the cloud gets thicker and the throat hit gets stronger.
- Effet. Most people find low and medium settings feel clearer and more head-focused, while high settings feel heavier and more body-focused. That’s a common experience, not a guarantee. Your tolerance, the strain and the amount you inhale all play a part.
There’s also a hard ceiling. Combustion starts in the region of 230°C (445°F), and burning plant matter creates tar and other byproducts you don’t want in your lungs. A good vape temperature stays well below that.
The temperature chart for cannabis flower
Use this as a map, not a rulebook. Ranges overlap on purpose, because devices differ and so do tastes.
| Paramètres | ° C | ° F | Déroulement |
|---|---|---|---|
| Low | 160 à 177 ans, qui | 320 à 350 ans, qui | Best flavour, light vapour, clear and gentle effects |
| Moyenne | 177 à 199 ans, qui | 350 à 390 ans, qui | Balanced flavour and vapour, mix of head and body effects |
| Haute | 199 à 210 ans, qui | 390 à 410 ans, qui | Dense vapour, toasty or peppery taste, heavy and sedating effects |
| Trop chaud | 220 et ci-dessus | 430 et ci-dessus | Harsh, wasteful, close to combustion |
These ranges line up with what most dry herb guides describe: lower temperatures favour flavour and lighter effects, the middle gives a balanced head and body feel, and the top end is intense, sedative and heavy on taste.
Low: 160°C to 177°C (320°F to 350°F)
Choose this range when flavour comes first. It’s a good fit for fresh, terpene-rich flower you want to enjoy slowly, or when you’d like to stay clear-headed. The vapour is thin, sometimes barely visible, and that’s normal. If you’re new to vaping flower, this is also a gentle way to learn how much you need.
Medium: 177°C to 199°C (350°F to 390°F)
This is the sweet spot for most people. At 180°C you get decent flavour and decent clouds, and the effects land somewhere in the middle. If you only ever want to set one number and forget it, 180°C to 185°C is a sensible default.
High: 199°C to 210°C (390°F to 410°F)
The top of the range is for people who want a heavy evening session, or for finishing off a bowl. You’ll get big vapour and a toastier, peppery flavour. It’s also where more of the flower’s compounds are used up quickly, so the same amount goes faster.
Why not just go as hot as possible?
Because hotter isn’t more efficient. Cannabinoids break down with heat, and the loss speeds up as you climb. In a 2026 lab study on hemp flower, CBD degradation became markedly faster above 200°C, with losses nearly doubling for every 20°C step from 180°C to 230°C, and reaching almost 58% at 230°C after 12 minutes. That study looked at CBD in hemp flower, but it shows the general pattern: more heat, more breakdown, and a point where you’re wasting what you paid for.
The practical rule is easy. Once you pass 200°C, you’re trading flavour and efficiency for density. Do that on purpose, not by default.
Raw flower, THCA and why decarboxylation matters
Dried flower contains mostly THCA, the acid form, not THC itself. Heat converts it to active THC. Health Canada’s research partners at the National Research Council point out that the term “THC” is ambiguous unless you say whether you mean THC or its acid precursor THCA. The same NRC work found that, even at room temperature (20°C), average monthly THCA and THC degradation was 2%, which is a good reason to keep flower stored well and not leave it in a hot car or on a sunny shelf.
For your vape, this means the heat you apply does two jobs at once: it converts THCA and it vaporizes the result. A vape set too low for too short a time may feel weak, and not because the flower is bad. Give each draw a few seconds to pull through, and give the device a minute to settle at its target temperature before the first hit.

How to step up your temperature in one session
Setting a single temperature works fine, but temperature stepping gets more out of the same load of flower. You start low, then raise the heat in small increments as the vapour thins out. The manufacturer Arizer Canada describes temperature stepping as a way to experience changing terpene profiles and vapour densities while extracting the herb more fully.
Here’s a simple routine to try:
- Grind lightly and pack loosely. A medium grind, not powder. Airflow matters as much as heat.
- Start at 175°C to 180°C. Take a few draws and notice the flavour.
- Step up 5°C to 10°C when the vapour gets faint, to somewhere around 185°C to 195°C.
- Finish at 200°C to 205°C if you want to use up what’s left. Stop there. Past about 210°C the flavour turns harsh.
- Taste the leftovers. Properly vaporized flower turns light brown and looks toasted, not black.
This sequence is close to what many experienced users do, and it lets you decide how far to go. If you only want a light session, stop after step 2 or 3 and save the rest for later.
Does the vape itself change the right temperature?
Yes, more than most people expect. Two devices both set to 190°C can taste and feel different, because of how they heat (conduction against convection), where the sensor sits and how much airflow cools the chamber.
- Conduction vapes heat the flower by direct contact with a hot chamber. They heat quickly, and it’s easy to scorch the edges if you pack too tight or draw too hard.
- Convection vapes pass hot air through the flower. They tend to be smoother and more even, and often want a slightly higher setting to produce the same cloud.
- Hybrides do a bit of both.
The best way to handle this is to find the lowest setting that still gives you enough vapour and then raise it only if you need to. Better devices make that easy. Arizer’s documentation for the Solo III says temperature can be adjusted in 1° or 10° steps and that you can save presets, which lets you build your own low, medium and high settings and recall them in one tap.
If you’re shopping for a device, we carry portable and desktop options on our accessories and devices page. Two we like for exactly this kind of control are the Storz & Bickel Venty vaporizer et la Arizer GO SRT.
Keep your vape clean
Residue changes airflow and taste, and it can affect air quality. Clean the chamber and mouthpiece regularly, and replace screens when they clog. Spare parts are easy to find: we stock a Haze V3 conduction screen pack et le Arizer Air and Solo screen pack, Ainsi qu'un glass aroma tube for the Air and Solo.
Perspective: how we’d set your vape
We talk to flower customers every day, and the same thing comes up: people chase a magic number when the real answer is a small range plus a bit of attention. Here’s how we’d approach it.
Start at 180°C and change one thing at a time. If the flavour is flat, drop 5°C. If you’re not getting enough vapour, go up 5°C. Changing grind, packing and temperature all at once makes it impossible to learn what helped.
Buy for the flower, not just the device. Fresh, well-cured flower from a licensed producer vaporizes better at lower temperatures, because the terpenes are still there to taste. Old, dry flower needs more heat and gives you less in return. That’s one reason we focus on craft flower from growers we trust, and why we list potency and terpene details on product pages where they’re available.
Treat vaping as lower-risk, not risk-free. Vaporizing flower avoids combustion, and research reviewing cannabis vaporisation notes that regulated dried flower is considered the safest vaporization product because it generally has lower THC potency (under 30%) than concentrates (70% to 90%). Lower isn’t zero, though. Long-term studies are still limited. If you have a respiratory condition, are pregnant or have questions about cannabis and a medication, talk to your doctor or pharmacist first. We’ve written more on the trade-offs in vapoter contre fumer du cannabis.
Know your dose. Heavier settings and bigger bowls mean more THC reaches you, faster. Start with a small amount, wait, and only then go again. If you’re weighing flower against stronger products, see our breakdown of concentrés vs fleurs.

What temperature for CBD flower?
CBD has a lower vaporization range than THC, and CBD-rich flower generally does well at the low-to-medium end. Many dry herb guides suggest staying roughly between 160°C and 185°C for CBD flower, which keeps flavour intact and avoids the heavier compounds that arrive at higher heat. Remember the hemp flower study above: CBD losses accelerated sharply once temperatures passed 200°C, so there’s little reason to push a CBD session past that point.
A good plan is to start at 170°C to 175°C, step up to 185°C if the vapour thins out, and stop there. CBD flower is usually less potent in THC, so you’ll often need a slightly bigger bowl to feel anything, and that’s fine. Always check the label for the THC percentage so you know what’s in the bowl.

Troubleshooting: common temperature problems
| Problème | Cause probable | Fixer |
|---|---|---|
| Weak or no vapour | Too cool, or packed too tight | Raise 5°C, loosen the pack, wait for the device to reach temp |
| Harsh, hot or coughing | Too hot, or drawing too fast | Lower 10°C, slow your draws |
| Goût de brûlé | Overheated or dirty chamber | Clean the device and lower the setting |
| Flavour fades quickly | Started too high | Start at 170°C to 175°C and step up |
| Flower looks black after | Combustion or very high heat | Drop the temperature; check your device’s accuracy |
| Effects feel too intense | High setting, big bowl | Go back to 175°C to 185°C, use less flower |
Pre-rolls, bowls and other ways to enjoy flower
If a dry herb vape isn’t for you, flower works in other formats. Pre-rolls are the simplest option for casual use and need no temperature setting at all, though you’re burning the flower, so they don’t have the same advantages as vaporizing. Browse our pre-rolls and flower to see what’s in stock this week, including options such as Pink Frosting Smalls from Faded. If you prefer a hybrid approach, a flower bowl device like the Puffco Proxy flower bowl lets you use ground flower with a device built for it.

QFP
What is the best temperature to vape weed?
For most people, 180°C (356°F) is the best place to start, with a useful range of 175°C to 195°C. Go lower for flavour and a lighter effect, or higher for thicker vapour and a heavier feel. Adjust in 5°C steps until it suits you.
What temperature destroys cannabinoids?
Cannabinoids degrade gradually as heat rises, with no single cut-off. In a 2026 hemp flower study, CBD losses sped up above 200°C and were nearly 58% at 230°C after 12 minutes. Combustion begins around 229°C (445°F), so stay well below that.
How do I smoke flower in a vape?
Grind the flower to a medium consistency, load the chamber loosely, set the temperature to about 180°C and let the device heat up fully. Draw slowly for a few seconds at a time. You’re not burning anything, so you’ll see vapour, not smoke.
What temperature should I vape CBD flower at?
Start around 170°C to 175°C and step up to roughly 185°C if needed. CBD flower does well at the lower end, and there’s little benefit in going above 200°C. Check the label for THC content before you begin.
Is a higher temperature stronger?
Not exactly. Higher temperatures produce denser vapour and heavier effects, but they also break down cannabinoids faster and can taste harsh. A moderate temperature with a well-packed chamber often feels better than a hot one.
