Dab Like a Pro: Cold Start vs. Hot Start Explained

Home > Blog > Dab Like a Pro: Cold Start vs. Hot Start Explained

Do you know how hot your banger gets? Chances are, it's red hot, hitting well over 600°F before you dab in the concentrate. Technically, this makes it a hot start dab, and while it will deliver intense effects, did you know it may be actively degrading the nuance and flavor of each dab?

Hot-start dabbing (heating the nail first, then adding concentrate) is the traditional way to dab. But there is another way: cold-start dabbing (adding the concentrate first, then heating the nail). Not only does this method lead to smoother hits, but low-temps also preserve terpenes, capturing all that authentic flavor you've been chasing.

Here is the lowdown on why dab temperatures matter, using the differences between hot start and cold start methods as a prime example.

The Basics of Dabbing

Dabbing is a method of consuming cannabis concentrates through vaporization using a dab rig, dab pen, or similar system. A single dab of concentrate delivers high levels of cannabinoids for intense effects that come on quickly, something that many experienced cannabis lovers look for.

From the outside, the entire setup can feel complicated, but the process is actually simple:

The nail or banger is heated using a torch.
A "dab" of concentrate gets added to the hot surface with a dab tool.
The concentrate vaporizes.
The vapor is inhaled through the mouthpiece.

It only gets complicated because there are a million ways to customize the setup, with terp pearls, spinners, electric torches, infrared thermometers, and any number of other fun add-ons.

Not to mention how different temperatures affect the entire experience. By playing with your method of hitting the dab, you can get a lot more out of every session than just intensity.

What is a Hot Start Dab?

Torch Heating Glass Dab Rig with Concentrate Ignition

A hot start dab is the traditional method, the one experienced cannabis consumers are probably most familiar with. It starts with the usual setup (your loyal dab rig), a torch heating up the nail, and then the dab of concentrate.

Pros:
Traditional method
Rapid onset of effects
Intense experience
Cons:
Harsh inhale
Challenging to get the exact temperature
Burns terpenes

With the simplest setups (no heat gun, no e-torch), the nail usually gets red hot, somewhere between 550°F and 700°F. In this hot start scenario, the dab instantly vaporizes on contact, helping achieve a rapid onset of intense effects.

But just because it's the traditional way to dab doesn't mean it's perfect. Unless you have an infrared thermometer, a hot start makes it difficult to hit the ideal temperature, and more often than not, you'll be burning off the terps.

Hot start dabbing is really best for thick and stable concentrates like shatter, badder, or crumble that can handle higher heat. Save your high-terpene sauces for a gentler approach: cold start.

What is a Cold Start Dab?

Want to try something new? Enter the cold start dab.

Pros:
More flavor
Greater nuance of effects
Smoother hit
Cons:
More residue in the banger
Less intense clouds

Cold start dabbing—also known as reverse or low-temp dabbing—flips the traditional method. Instead of heating first, you start by loading your concentrate into a cool banger.

With the dab in place and the carb cap on, apply heat with the torch. As the temperature rises, the concentrate quickly melts and begins to vaporize. Following this method, temperatures peak around 400°F to 500°F.

The inhale from a cold start will still be appropriately intense, but you'll get a much more flavorful experience rich in all the terpenes you paid top dollar for.

This cold start method also aims to preserve the full spectrum of cannabinoids beyond THC, for an experience that may feel more nuanced thanks to compounds playing off each other in the entourage effect.

The downside of a low-temp dab is that sometimes you'll find a bit of residue left on the nail. You also won't always get the same big voluminous clouds on the exhale. So, save the cold start for your high-end, saucier concentrates: live resin, live rosin, sauce, terp sugar, budder, or diamonds in terp sauce.

What is the Ideal Dab Temperature?

While there aren't any hard-and-fast rules about the exact temperatures for hot vs. cold dabbing, generally speaking, cold-start dabs hit a lower peak temperature than hot-start dabs.

But what does that usually translate to in terms of temperature? Consider this your dab temp guide:

Cold Start: 400°F–500°F

Lower temperatures help preserve lighter, more volatile terpenes, which are prone to burn off at higher temperatures. The same holds true for some of the mellower cannabinoids in a full-spectrum concentrate.

Hot Start: 550°F–700°F

Higher temperatures vaporize each dab more efficiently, meaning minimal residue in the banger. But this method will frequently burn off many of the more sensitive terpenes and cannabinoids. Sessions with high temperatures center around THC's effects and big vapor clouds.

But wait! How do you even know what dabbing temperature you are hitting?

Unless you have a high-end dab rig with a built-in temp check or an e-torch for precision, you'll want to grab an instant-read infrared thermometer. It sounds fancy, but they are under $20 on Amazon.

The Science Behind the Difference

The differences between cold start vs. hot start aren't just something made up by stoners. It's based on cold, hard science.

This is because when you dab, you are technically evaporating the concentrate into an inhalable vapor. Just like water evaporates at 212°F, each cannabinoid and terpene has its own slightly different vapor point.

For example, THC starts at around 315°F, while THCV begins at 428°F. Terpenes are even more volatile; the citrusy kick of limonene expresses at 350°F, while the floral notes pop off around 388°F.

As a general rule, high dabbing temperatures will start to burn the more volatile compounds. This will lead to a harsher inhale with one-note effects. A cold start preserves more of the entourage effects (the synergy between cannabinoids and terpenes) for a more balanced high and a smoother hit.

Head-to-Head: Which Is the Right Dab Temperature for You?

Do you know what you want out of your next session? There is no wrong answer here. It's all about crafting a dab session around what you love. But finding your perfect dab starts with an experiment. Try the same concentrate at different temperatures to explore subtle differences in flavor and effects.

Here is a rapid-fire rundown of what to expect with the cold start dabs vs. the regular dab method:

Goal	Hot Start	Cold Start

Pro Tips for Better Dabs, No Matter the Temperature

Part of the draw of a dab rig is the ritual: setting up the rig, prepping the concentrate, heating the nail to the exact temperature, and then, of course, the inhale for monstrous clouds.

But the other reason people love dabbing is the level of customization. Every session offers new opportunities to experiment with different temperatures or make fun additions to the rig itself.

Sure, the intense effects are the initial attraction, but for many OG dabbers, they've fallen in love with the process as well. If that sounds like you, here are even more ways to upgrade that next session:

Concentrate Storage

Great dabs start with great concentrates, which means proper dab storage is paramount. Like with cannabis flower, heat, light, and oxygen are terpene killers, so keep concentrates in a cool, dark place, preferably in an airtight glass container.

Upgrade to an E-Rig

Although a torch is the traditional heating method in the dab universe, if you really want to hit exact temperatures, get an e-rig. E-rigs (electronic rigs) let you hit consistent temperatures of your choosing. You don't have to make a rough guess; instead, you'll hit your choice of hot or cold starts perfectly, every single dab.

Experiment With Temps

Speaking of temperatures, if this guide has taught you nothing else, it's that you should experiment more with your dabs. The best part? You can start with the concentrate you have on hand today! Try hot, try cold, play with a few temperatures within each, to feel exactly how the temp affects the overall experience.

Add Terp Pearls

Terp pearls are tiny quartz balls, placed inside the nail that spins as you inhale. As they swirl around in the concentrate, they help evenly distribute the heat for more effective evaporation. What does this mean for you? Less waste, more flavor, and way-smoother dabs.

Clean Your Gear

All else aside, a clean ride is going to leave a better taste in your mouth. Use ISO alcohol and cotton swabs, and don't be afraid of getting into the hard-to-reach crannies. For real flavor friends, after every dab, do a quick wipe of the banger to clean up any residue.

What Team Are You On: Hot or Cold?

After that information download about hot start dabbing and cold start dabbing, what are you going to try for your next session? High temps deliver intensity and massive clouds, while lower temps bring out the concentrate’s nuanced effects and authentic cannabis flavor.

Remember, there is no right answer. The beauty is that you get to curate the experience to what you love best and switch it up every session!
