Taste/Smell- Flavor will slowly diminish
You can tell that your weed is done when it starts to lose its flavor. You’re familiar with how bubble gum eventually loses its taste after you’ve been chewing for a while. Well, a similar principle applies to marijuana, once it has been vaped to completion. All the terpenes that give each strain of marijuana its distinctive taste will have been used up, leaving the herb free of flavor.
A dry herb vaping session usually starts extremely flavorful & aromatic, and loses flavor as the session progresses. Once you feel a sharp drop of flavor and the vapor becomes harsh, your weed is done.
Once your herb has been thoroughly vaped, it starts to lose that sweet aroma. If you do it for long enough, it starts to take on a scent very similar to burnt popcorn, which is an unpleasant—but very noticeable—odor that no one likes. If you get that smell, it means that you vaped it way too much. If that’s what you’re smelling, it is time to dump the herb in your chamber for a new batch.
Looks/Texture- Will become brown and crunchy
Normally, fresh herb is a bright green color, but once it has been cashed, all the color is drained out of it and it takes on a distinct brown color. As with any plant matter, Brown color is not a good thing and marijuana is no different. You can take a quick look at your herb chamber while vaping. If it’s a solid brown, your session is done.
Any good herb is soft and fluffy and it should retain that texture even after it has been completely ground up. Once it has been completely vaped, it becomes stiff, brittle, and it crumbles easily. You can examine the texture of your herb after your session and make improvements during your next sessions.
With the Pax 2 or Pax 3- You can open the oven lid and look at your herb. If you want to get super efficient, stir your herb once or twice during a session. It will circulate the herb in the oven and will make it vape more evenly.
Of course never touch herb as it comes out of the chamber. It’s hot.
Know Your Vape- Experiment and improve
Most vapes have a preset “session duration,” which is typically between 5-10 minutes. One of the best ways to gauge the right amount of time is by trial and error. Using the techniques mentioned above, practice a few times until you know exactly how long it takes for the weed to be fully exhausted in your vaporizer.
Once you figure out how long herb lasts with your specific vape on a certain temperature level, you can time future sessions to achieve perfectly vaped herb. It’s a matter of trial and error, and experimentation will take your vaping to the next level.
With the Pax 3, it depends on the temperature settings. But generally I get around 5 minutes of really good fresh flavor, then it slowly declines. I start with temperature 3, and increasing to 4 towards the end. With these settings I get around 6-9 minutes of vaping, and at the end the weed is completely cashed.
Over time, examine your herb after sessions, and fine tune your session length for a perfectly cashed herb.
Maximize your herb usage
There are a few things you can do to maximize the lifespan of your herb:
Low TemperatureVaping – Vaping at the lower temperature settings on your vaporizer will make your weed last a lot longer. Not only does it extend the life of your herb it is also a pretty pleasant experience since lower temperatures tend to bring out the flavor a lot better than higher temperature settings. You can try starting a session low and gradually increasing the temp to max out your herb.
- Grind Your Herb Thoroughly – A nice, comprehensive grind makes your weed last for a long time because it maxes out the surface area of your weed, so you can get great vapor using less herb. This saves your herb’s flavor and it saves you money since you can use less with each session.
