A hot start means heating your banger past temperature first, letting it cool to your target, then dabbing. A cold start (sometimes called a reverse dab) means loading the concentrate into a cool banger first, then applying gentle heat until it vaporizes . The single most important thing to know: the two methods produce vapor at very different thermometer readings. A cold start typically comes off around 400–500°F, well below hot-start ranges, so you can't use the same number for both. Hot start dabs: the traditional method How it works: Heat the banger with a torch, stop, and let it cool for a set time (often 30–60 seconds) down to your target surface temperature. Then drop in the concentrate and inhale. Pros: Fast, familiar, and the vapor comes on immediately. Cons: Timing is a guessing game. Torch strength, quartz thickness, and airflow all change how quickly the banger cools, so "count to 45" rarely lands on the same temperature twice. Overshoot and you scorch the terpenes. The standard dab temperature ranges you see published, including ours (roughly 500–600°F for most concentrates ), are hot-start surface temperatures. Hot starts reward precision, which is exactly why measuring the surface instead of counting seconds is such an upgrade. Cold start dabs: the forgiving method How it works: Put the concentrate into a room-temperature banger, cap it, then apply gentle heat from below until it starts to bubble and vaporize. You're bringing the whole system up slowly instead of dropping the material onto a preheated surface. Pros: More forgiving on timing, great flavor because the concentrate never hits a scorching surface, and efficient, with less chance of instantly charring the material. Cons: Slower to get going, and it's easy to underheat and leave a puddle if you stop too soon. Cold starts are especially popular for flavor-forward, terpene-rich concentrates like live rosin and sauce, where protecting taste is the priority. It's the same flavor-versus-vapor tradeoff that separates low-temp and high-temp dabbing. The key difference: the numbers are not interchangeable This trips up a lot of people. On a cold start, the concentrate heats up together with the quartz instead of landing on a preheated surface, so it starts producing vapor at a much lower thermometer reading, typically around 400–500°F . Chase a 550°F reading on a cold start and you'll blow right past the flavor window. On a cold start, pull the heat as soon as it's vaporizing steadily, not when the gauge hits a hot-start number. Cold start vs. hot start at a glance Factor Hot start Cold start Order Heat first, then dab Load first, then heat Target reading ~500–600°F surface, then drop in ~400–500°F, pull heat once vaporizing Speed Fast Slower Flavor Great when timed right Excellent Forgiveness Timing-sensitive More forgiving Best for Experienced users, speed Flavor chasers, beginners The reliable way to nail either method Guessing by seconds is where both methods go wrong. Two things fix it: Measure the temperature with an infrared thermometer like the Dab Rite PRO, so you know your real surface reading instead of estimating. Know your target. The maker's recommended range for your specific concentrate is published on the Best Temp Index . Scan the QR code on the label or search the brand directory . Those targets are hot-start surface temps, so if you cold start, use them as a flavor guide and expect to pull heat at a lower reading.

## FAQ

**What is a cold start dab?**

A cold start (reverse dab) means placing the concentrate into a room-temperature banger and then applying gentle heat until it vaporizes, rather than heating the banger first. It's forgiving and flavor-friendly, and it vaporizes at a lower thermometer reading (~400–500°F) than a hot start.

**Is a cold start or hot start better?**

Cold starts are more forgiving and often more flavorful; hot starts are faster and more traditional. Beginners and flavor chasers tend to prefer cold starts.

**What temperature is a cold start dab?**

On the thermometer, a cold start typically begins vaporizing around 400–500°F — noticeably lower than hot-start ranges. Don't apply hot-start numbers (500–600°F) to a cold start; pull heat as soon as it's vaporizing steadily.

**Do cold start dabs save concentrate?**

They can be more efficient, because the material vaporizes gradually instead of potentially charring on a pre-heated surface.
