Start at 175°C. For flower in a dry herb vaporizer, most people land between 175°C and 195°C for a balance of flavor and visible vapor, then step up toward 210°C to 220°C if they want the heavier, toastier end of the bowl. Below about 160°C you get thin vapor and mostly aroma. Above 230°C you are flirting with combustion and a harsh hit.
The quick chart
- 155°C to 165°C: Aroma chaser range. Light, wispy vapor, bright terpene notes, very little body.
- 165°C to 175°C: Flavor forward. Good for a first draw on a fresh bowl, especially with fruity or piney strains.
- 175°C to 190°C: The everyday zone. Solid vapor density, most cannabinoids and terpenes are active, flavor holds up.
- 190°C to 205°C: Warmer, denser, more sedating. Flavor starts to taste roasted rather than fresh.
- 205°C to 220°C: Heavy extraction range. Best for end of session or for flower that still has something left.
- Above 230°C: Combustion territory. Skip it unless your device is designed for it.
Why the number changes the experience
Terpenes and cannabinoids do not all vaporize at the same point. Terpenes are light molecules and mostly release at the low end, which is why a 165°C draw tastes better than a 220°C one. Cannabinoids are heavier and need more heat to turn into vapor at a useful rate. A temperature chart is really a map of which compounds you are inviting into the hit.
Advancing temperature through a session, rather than blasting one high number from the start, is the method I use most. You get the flavor first, then the density, then the tail end of the bowl.

Terpene boiling points worth knowing
- Pinene: around 155°C, which is why pine notes show up on the first puff.
- Myrcene: around 167°C, the earthy, herbal note in many indicas.
- Limonene: around 176°C, citrus and brightness.
- Linalool: around 198°C, floral and lavender leaning.
- Beta caryophyllene: often listed near 119°C, so it is in the vapor early.
Cannabinoid boiling points
- THC: around 157°C.
- CBD: roughly 160°C to 180°C depending on the source cited.
- CBN: around 185°C, one reason older material can feel more sedating at higher heat.
- CBC: around 220°C, at the top of the useful range.
What about oil cartridges?
This is where most charts confuse people. A 510 thread cartridge battery usually sets voltage or wattage, not degrees Celsius, and the coil temperature is not the same as the oven temperature in a dry herb device. For carts, lower voltage means cooler coil and better flavor. Many users run 2.4V to 2.8V for taste and 3.0V to 3.3V for bigger clouds. Pushing a cart hard cooks the oil and can taste burnt, and the terpenes degrade first. If your battery shows temperature in Celsius, treat 160°C to 200°C as the sane window for oil and expect flavor loss as you climb.
A simple session plan
- Grind medium, pack loose, and let the device heat fully before the first draw.
- Start at 170°C and take two slow draws.
- Step to 185°C for the middle of the session.
- Finish at 200°C to 210°C if the vapor still tastes fine.
- Stop when it tastes like popcorn. That is the bowl telling you it is done.
Practical notes
Device readouts drift. A 10°C gap between two vaporizers at the same setting is normal, so tune to taste and vapor quality rather than to a number on a screen. Draw speed matters as much as heat: a fast, hard pull cools the oven and thins the vapor. Long, slow draws hold temperature and give you more control. Give the oven 20 to 30 seconds to recover between draws on session-style devices.
Keep your cannabis legal and from a licensed shop, and be careful with unregulated cartridges. The 2019 lung injury outbreak was tied to illicit vape products, not to regulated dispensary oil. Buy from a licensed retailer, check the label, and store carts upright and away from heat.
