Dry-Herb Vaporizer Temperature Guide (2026): Every Band

Here is the whole range in one table. These are the bands the makers publish and that owners consistently converge on across the sources we track, not measurements of ours, and there is nothing magical about the boundaries: the transitions are gradual and the numbers are approximate.

Above roughly 220 C, or about 430 F, you are past the range most makers publish for dry herb and into territory where material begins to scorch rather than vaporize. That produces harshness and no benefit, and most devices simply do not offer settings up there. If your device's own published range is narrower than this table, follow your device.

The mechanism behind the whole range is straightforward. Plant material contains a spread of aromatic and active compounds with different boiling points. At the low end of the range, only the lightest and most volatile of those come off, which is why low-temperature vapour tastes the most like the material smells and why it is so thin. As you raise the temperature, progressively heavier compounds join in, so the vapour gets denser and warmer while the delicate top notes get buried under everything else.

That is the entire trade, and it explains a set of observations that otherwise seem contradictory. Low temperature sessions produce almost no visible vapour and yet plenty of flavour, which convinces many new owners that their device is broken. High temperature sessions produce impressive clouds and a flat, slightly toasted taste. Neither is a defect, and both are useful for different reasons on different evenings.

The other thing that changes across the range is how fast a load exhausts. At the low end you can get a long, slow session out of one chamber. At the high end the same chamber is finished in a handful of draws. If you find yourself refilling constantly, running cooler is the fix, and it costs nothing to try.

The single most useful habit in this whole guide is not picking a number, it is moving through several. Start at the low end of your intended range, take a few draws, then raise the temperature ten to fifteen degrees when vapour production drops off. Repeat until the material is evenly browned. A typical progression might be 180 C, then 190 C, then 200 C, or 356 F, 374 F, 392 F.

This works because different compounds come off at different points, so a fixed setting is always leaving something behind. Stepping up harvests the light material first, while it can still be tasted, then goes back for the heavier fractions once the lighter ones are spent. Owners consistently report that this produces a longer, more consistent and better tasting session than picking one setting and staying there, and the reasoning is sound: a chamber that has stopped producing at 180 C has not stopped producing, it has stopped producing at 180 C.

The finishing cue is visual rather than numerical. Material is done when it is an even light-to-medium brown all the way through. Green patches mean there is more to be had, and often mean the load needs stirring as well as heating. Dark brown or black means you have gone past the useful range and are now heating spent material, which adds harshness and nothing else. The full session routine is in how to use a dry-herb vaporizer.

Two devices set to 190 C can deliver noticeably different sessions, and the reason is usually architecture rather than accuracy.

A session device brings a whole chamber up to temperature and holds it there across a series of draws over several minutes. The material sits in a hot environment continuously, so extraction proceeds between draws as well as during them, and a load progresses steadily whether you are drawing or not. This is why session devices reward a steady rhythm and why leaving one running while you get distracted wastes material.

An on-demand device heats only while you are drawing. Between draws nothing is happening, so nothing is lost, and a chamber can sit half-used for an hour without degrading. The practical effect is that the number on the display describes the air arriving during a draw rather than the environment the material lives in, which usually means an on-demand device at a given setting feels a little more intense per draw and a lot less wasteful overall.

Heating method layers on top of this. Convection devices generally track their displayed temperature more closely at the material, because hot air arrives at a controlled temperature. Conduction devices show a chamber temperature while the centre of the load runs cooler, which is why a conduction device at a given setting often behaves like a convection device at a lower one, and why stirring changes the result so much. The mechanics are broken down in convection vs conduction.

Two variables sit upstream of the temperature dial, and both will make a perfectly good setting behave badly.

Grind. A vaporizer moves hot air through packed material, so the bed is part of the machine. When the grind is uneven, air channels through the loose spots: the material along that channel is exposed to far more hot air than the display setting implies, while the rest of the load barely warms. The result is a session that tastes scorched at the start and produces nothing by the fourth draw, at a setting that would have been fine with an even bed. The target is medium-fine and uniform, roughly coarse-ground-coffee texture, which is what a good grinder such as the Santa Cruz Shredder 3-piece medium at $59.90 produces. The full field is ranked in best herb grinders.

Moisture. Water absorbs heat. A damp load spends the early part of a session having its moisture driven off before vapour production really begins, which reads exactly like an underpowered device or a setting that is too low, and it tempts people into running hotter than they need to. Material that has dried out too far causes the opposite problem: it crumbles to powder in the grinder, and powder packs into a dense plug that blocks airflow entirely.

The fix for both is stable storage: a container that seals, with a two-way humidity pack inside it. Boveda 58 percent size 67 four-packs are $23.99, and many dry-herb vaporizer owners report preferring that drier setting on the reasoning that drier material grinds and vaporizes more evenly, while 62 percent at the same $23.99 is the more common general-storage choice. That is owner consensus rather than a manufacturer recommendation, and it is argued out fully in Boveda 58 vs 62.

If flavour is the point: start at 175 to 185 C, or 347 to 365 F, and step up slowly. Expect light, cool vapour and accept that the visible cloud is not the measure of anything. A good grind matters most here, because at low temperatures there is no excess heat to paper over an uneven bed.

If you want a balanced default: 185 to 195 C, or 365 to 383 F. This is where we would tell anyone to begin with a new device, because it produces reliable results without being at either extreme, and it gives you a clear reference point to move away from in either direction.

If you want density: 200 to 210 C, or 392 to 410 F. Warmer on the throat, faster to exhaust a load, and noticeably flatter in taste. Perfectly reasonable if that is what you are after, though most owners who start here end up drifting downward once they have tried the lower bands.

If a load is nearly finished: a final push toward 215 to 220 C, or 419 to 428 F, extracts the last of the heavy fraction before the material is spent. Watch the colour rather than the clock, and stop at even brown. Beyond that you are heating ash.

Whatever you settle on, the supporting kit does more for consistency than the last ten degrees ever will. The grinder, the sealed jar and the humidity pack are covered in best vaporizer accessories, and keeping the airpath clear, which quietly changes how a device performs at any setting, is covered in how to clean a dry-herb vaporizer.
