Frequently Asked Questions
How do I use this vaporization temperature calculator?
Use the interactive slider or manual input to set your desired temperature. The calculator instantly shows which cannabinoids and terpenes become active at that temperature. You can switch between Celsius and Fahrenheit, try the preset temperature profiles, and toggle terpenes on/off to customize your results.
What temperature should I vape dry herb at?
It depends on your goals: Low Heat (140-170°C/284-338°F) preserves flavor and terpenes with mild effects. Medium Heat (170-190°C/338-374°F) offers balanced flavor and potency. High Heat (190-220°C/374-428°F) maximizes extraction but may reduce flavor. Very High (220°C+/428°F+) extracts all compounds but approaches combustion.
What are cannabinoids and why do they matter?
Cannabinoids are compounds found in cannabis that interact with your body's endocannabinoid system. Each has different boiling points and effects: THC (psychoactive), CBD (non-psychoactive wellness), CBG (focus), CBN (sedation), and others. Understanding their vaporization temperatures helps optimize your sessions.
What's the difference between cannabinoid categories?
Psychoactive: May alter perception, mood, or consciousness (THC, Delta-8-THC, THCV)
Non-psychoactive: Provide potential benefits without intoxication (CBD, CBG, CBC)
Mildly psychoactive: Subtle effects on consciousness (CBN)
Precursor: Raw acid forms that convert when heated (THCA→THC, CBDA→CBD)
What are terpenes and the entourage effect?
Terpenes are aromatic compounds that give plants their scent and may influence effects. In cannabis, they work synergistically with cannabinoids in the "entourage effect" - where compounds work better together than alone. For example, myrcene may enhance relaxation, while limonene may boost mood.
Why do different vaporizers show different results?
Vaporizer efficiency varies by design. Convection vaporizers heat air around material, while conduction heats through direct contact. Desktop units often reach higher temperatures more consistently than portables. Material moisture, grind consistency, and pack density also affect results.
How accurate are these vaporization temperatures?
These temperatures are based on scientific research and laboratory data for pure compounds. Real-world vaporization can vary ±10-20°C due to device efficiency, material quality, humidity, and individual device calibration. Use these as starting points and adjust based on your experience.
Can I use this for concentrates or other materials?
This calculator is designed for dry herb vaporization. Concentrates, oils, and waxes may have different optimal temperatures due to extraction methods and additives. Always consult your device manual and start with lower temperatures when trying new materials.
What happens at very high temperatures? When does combustion occur?
Combustion typically begins around 280-300°C (536-572°F) for dry plant material. At 250°C+ you're approaching the combustion zone where material may start to burn rather than vaporize. Our calculator shows warnings at these temperatures. High-temperature compounds like THC-O and oxidized terpenes vaporize in this range, but the risk of combustion increases significantly.
