A dry herb vaporizer heats cannabis to release cannabinoids and terpenes as vapor instead of smoke. The core process is the same whether you own a budget portable or a flagship desktop: grind, pack, heat, draw, clean. The details shift a little with your choice of vape, or browse our best portable vaporizers and best budget vaporizers if you're still shopping.
The same beginner mistakes come up again and again. Grinding too coarse, packing too tight, pulling too hard, skipping cleaning. They're also the first things to check when a session feels off, and our troubleshooting guide covers the rest. This guide walks through every step, from first use to saving your spent cannabis. Here's the short version:
- Grind medium-fine, about the texture of coarse salt.
- Load the oven firm but springy, level with the rim.
- Heat to 180°C and wait for the ready signal.
- Draw slowly for 5-10 seconds, stepping up 5-10°C every few draws.
- Tap out the brown spent cannabis and brush the oven once it cools.
What you need before your first session
- A charged vaporizer, or a desktop plugged in.
- A grinder, ideally a 4-piece so the grind stays fluffy. Our grinding guide covers the technique.
- A cleaning brush and packing tool. Most vapes ship with both in the box.
- Cotton swabs and isopropyl alcohol for deep cleans.
- Optional extras: dosing capsules if your vape takes them, and a water adapter for smoother hits (using a vape with a bong).
Our vaporizer accessories guide covers the rest of the kit worth owning.
Prep your vaporizer before your first session
Before your first load, check the chamber and mouthpiece for debris, make sure everything is put together properly, and charge the battery. Then run one empty heat cycle. It lets you learn the controls and catch any odd smell before cannabis goes in.
How much prep you need depends on the model. Healthy Rips calls for one five-minute empty cycle at 221°C on the Fury 3, after a full charge. Storz & Bickel runs a First Flow process at the factory, so a new Mighty+ or Venty needs no cleaning before first use. If a chemical smell hangs around after your first cycle, don't keep heating until it fades. Check for debris, packaging bits or a loose part, and contact the maker if it won't clear.
Tip
Grind to medium-fine consistency for best results
Grind quality has a big effect on vapor production, and it's one of the easiest things to get right. A medium-fine grind (about the texture of coarse salt) exposes plenty of surface to the heat while leaving room for air to move through the oven.
Too coarse, and big chunks heat unevenly while hot air slips around them. Too fine (powder-like), and the material can compact into a dense plug that chokes airflow, or slip through the screen. Our complete grinding guide covers grinder types and technique in detail.
Your heating method matters too. Conduction vaporizers heat cannabis through contact with the hot oven walls, so they like a finer grind and a firmer pack. Convection vaporizers push hot air through the load, so they want a lighter pack that leaves the air a path. Tinymight recommends a medium-fine grind for its convection oven. Hybrids like the Venty and Mighty+ use both, so start medium-fine and adjust from there.
Then there's moisture. Damp, freshly opened cannabis spends its heat boiling off water and gives thin, steamy hits, while bone-dry flower grinds to dust. Store it in an airtight jar with a humidity pack so it stays springy, not crumbly.
Medium-fine: fluffy and even, with a few larger pieces. Powder is too far. Illustration.
How to load a dry herb vape: firm, not tight
How much fits depends on the chamber. The Fury 3 holds about 0.2 g, while the Mighty+ fits up to 0.3 g. Fill the chamber, then gently tamp with your finger or the packing tool until it feels firm but still slightly springy. On the Venty, Storz & Bickel's instructions say to fill right to the rim without packing it tight.
| Heating type | Grind | Pack | Examples we've reviewed |
|---|---|---|---|
| Conduction | Medium-fine to fine | Firm, springy, full to the rim | PAX Mini 2, PAX Plus |
| Convection | Medium to medium-fine | Light and loose, never pressed hard | XMax V4 Pro, Tinymight 2 |
| Hybrid | Medium-fine | Firm but springy | Mighty+, Venty, Fury 3 |
In a conduction oven, a firm pack keeps the cannabis in even contact with the hot walls and pulls air through it instead of around it. An overly tight pack chokes airflow and gives thin, wispy vapor with little flavor. If the draw feels much harder after loading, loosen it up and check the screens.
Dosing capsules offer a mess-free loading alternative. Pre-fill the aluminum capsules at home, drop one into the oven, and swap it out after each session. The Mighty+ and Venty both take Storz & Bickel's capsules, which keep the oven cleaner between deep cleanings and make packing on the go almost effortless. Let a used capsule cool before you grab it, and see our dosing capsule guide for loading tips.
Level with the rim, not mounded above it, so the top closes without squashing the load.
Start at 180°C and step up through your session
Temperature shapes how the vapor tastes and feels.
| Setting | Range | What you get |
|---|---|---|
| Low | 170-185°C | Light, thin vapor with the brightest flavor |
| Mid | 185-195°C | Fuller clouds, flavor still holds up, where most sessions settle |
| High | 195-210°C | Dense, toasty vapor for the end of a load |
Past 210°C, the flavor turns harsh fast, so treat it as a finishing step, not a starting point.
We recommend starting at 180°C, the factory setting on the Mighty+ and Venty, and bumping up by 5-10°C every few draws. This "temperature stepping" approach lets you enjoy the full flavor of your cannabis before chasing thicker vapor toward the end of the session. Our temperature guide goes deeper on what changes as you turn up the heat.
If your vaporizer uses presets instead of exact degrees, check your manual for what each level means. Pick the one closest to 180°C and work up.
180°C, the Mighty+ factory setting and a good place to start.
If you taste the cannabis but see almost no vapor, run through the checks below, then nudge the temperature up. If the flavor turns harsh and acrid within the first few draws, you're running too hot, so drop it a notch.
Take slow, steady draws
Draw slowly and steadily for 5-10 seconds. Fast, hard pulls can outrun the heater and leave you with thin, unsatisfying clouds. It's an easy way to convince yourself your vaporizer is broken.
When vapor goes missing, run through the usual suspects: grind too coarse, pack too loose, temperature too low, or an inhale that's too hard. A low battery, a vape that hasn't finished heating or a poor mouthpiece seal can do it too.
Warning
Session vaporizers stay hot for a set time whether you inhale or not. Timers vary: the Fury 3 lets you choose three to seven minutes, the Mighty+ switches off three minutes after the last button press or detected use, and the Venty switches off after two minutes without use. On-demand heating only fires when you ask for it. On the Tinymight 2, you hold the button, wait for the ready buzz, then draw and let go. Timing every hit takes a more deliberate technique, and the Tinymight 2 also has a session mode if you'd rather skip that.
That difference decides whether you can pause. A session vape keeps cooking the load after you stop, so finish it in one sitting. With on-demand heating, like the Tinymight 2 in on-demand mode, the cannabis only heats while you hold the button, so you can take a hit now and finish the load later.
Draw resistance varies widely between models. The Venty's adjustable airflow is rated up to 20 L/min for wide-open pulls, and its heater responds as you inhale. Many budget portables have fixed, more restricted airpaths. Our draw technique guide explains how to adapt your inhale to different resistance levels and vaporizer types.
Desktops work the same way with more power behind them. The Volcano Hybrid runs both styles from one base: its balloon fills a bag you sip from, and its tube (a whip) takes a gentle pull as you would on a portable. See our best desktop vaporizers for the full field.
Slow and steady, at a pace that feels comfortable on your vape and its airflow setting.
Quick fixes
| Problem | First thing to try |
|---|---|
| No vapor | Charge it, wait for the ready signal, slow the draw to 5-10 seconds, then add 5-10°C. Still nothing? Check for a clogged screen or a leaky cooling unit. |
| Harsh or burnt taste | Drop 5-10°C, brush the oven, and check whether the load is already brown and spent. |
| Weak effects | Give it 10 minutes, step up to the mid band, and take a few more full, slow draws before judging. |
| Tight draw | Loosen the pack, then brush or swap the screen. |

How to tell when your cannabis is done
A session is done when the vapor thins out noticeably and the flavor shifts from sweet and fresh to a dry, toasted popcorn taste. How long that takes depends on your temperature, pack size and how often you draw.
Once the oven is cool enough to handle, tap out the spent cannabis. An even brown color is a good sign it heated evenly. Green patches point to uneven heating, so look at your grind, pack and technique. Black, charred bits, ash or a smoky taste mean it's getting hot enough to burn, so stop and turn it down.
Save your spent cannabis. AVB (already vaped bud) still holds leftover cannabinoids, and you can cook it into edibles, capsules or tinctures. Its strength varies a lot from load to load, so start small, label the jar, and keep it away from kids and pets.
Light, medium, dark. Aim for an even color. Green patches mean parts of the load stayed cooler, and black means it burned.
Brush after every session, deep clean when needed
Regular cleaning keeps your vapor tasting fresh and stops residue from choking airflow over time. Once the oven has cooled, brush it out after every session with the included brush. When brushing stops shifting sticky buildup, or the draw gets tighter, it's time for a deeper clean.
Switch the vape off, let it cool, and wipe the oven and cooling unit with a cotton swab lightly dampened with isopropyl alcohol, never dripping. Glass stems and mouthpieces can soak in isopropyl for a deeper clean once you pull off any O-rings or seals. Never submerge the powered body, and let everything dry completely before you heat it again. Our vaporizer cleaning guide walks through the routine part by part.
A quick brush-out after each session keeps residue from building up on the walls. Go gently around the screen.
