Set your dry herb vaporizer to 350°F (175°C) and step upward in 10°F increments from there. That one habit handles most flower, most devices, and most goals. Terpenes boil off first, THC and CBD follow, and the heavier sedative compounds sit at the top of the range. You keep adjusting until the vapor tastes right and the effect matches what you wanted.

Prerequisites
- A vaporizer with real temperature control, not just low, medium, and high presets.
- Flower that is cured and dry enough to crumble when you press a bud.
- A grinder that produces a medium grind.
- A clean oven or chamber with no leftover residue from the last bowl.
Steps
- Pinch a bud and check the moisture. It should feel dry on the outside with a little spring left, not damp and spongy.
- Grind the flower to a medium consistency, close to coarse table salt.
- Fill the chamber loosely, leaving a small gap at the top so air can move through the load.
- Set the temperature to 350°F for your first session on a new strain.
- Wait 20 to 30 seconds after the device reaches temperature so the herb heats through.
- Draw slowly for 8 to 10 seconds, the way you would sip hot tea.
- Note the flavor on the first two draws. Sweet and floral means you are in the terpene zone.
- Raise the temperature by 10°F to 15°F for the second session on the same bowl.
- Stop stepping up once you reach 430°F (221°C), which is the practical ceiling before combustion and harsh byproducts.
- Write down the temperature where the flavor and the effect both landed well, and use it as your default for that strain.
What Each Range Releases
- 310°F to 330°F (155°C to 165°C): Pinene and myrcene, plus a light THC lift. Best for daytime, clear-headed sessions.
- 330°F to 360°F (165°C to 182°C): Limonene and the bulk of THC. Flavor peaks here.
- 360°F to 390°F (182°C to 199°C): CBD and linalool come online. Balanced body and head effect.
- 390°F to 430°F (199°C to 221°C): CBN and the heavier compounds. Sedative, best saved for evening.
Common Mistakes
- Packing the chamber tight, which blocks airflow and scorches the center of the load.
- Starting at 400°F or higher, which burns off terpenes before you taste them.
- Grinding too fine, which pulls plant material through the screen.
- Drawing hard and fast, which cools the oven and wastes vapor.
- Reusing a spent bowl at high heat and judging the strain by that taste.
Temperature is the one variable you control on every session. Change one thing at a time, keep the strain constant, and the right setting for your flower shows up within two or three bowls.
