    VAPE 101 Part 4 - How You Know When Your Herb is Spent

    Knowing when to stop vaping comes intuitively to some, but for some people this can take some practice. You can't really use just one factor to determine if your herb is spent, so here are the main areas I look at:

    • Look
    • Taste
    • Smell
    • Clouds

    LOOK

    Spent herb won't look the same from every vaporizer, there will most definitely be some variations in the color and how even it is. AVB (Already Vaped Bud) is another term for spent herb, or what's left over when you're done vaping.

    Usually, and this is a general statement, your herb will darken considerably after being fully vaporized, and most often it will appear "dark brown" afterwards. However, some vapes don't get the AVB quite as dark, and there are also variations between conduction and convection units, as well as between strains of herb.

    Check out the pic below, these are all different loads of AVB from different vaporizers, and all of these are what I would consider "spent" even though there are variations in color:

    TASTE

    The taste of the vapor is another way you can tell that your vape session is nearing the end.

    Typically, when bud is completely vaped, it gives off the flavor and aroma of "burnt popcorn". However, before it gets to that point you will usually notice a gradual decline in taste throughout your session.

    As your material gets close to being spent there is less and less good stuff in it to be vaporized, so what also usually happens is it will start to taste or feel a little hotter or harsher towards the end. This is because you still have the same level of heat going through the chamber but now there's less stuff turning into vapor, so you end up just breathing in more hot air at the end.

    Taste is another area that will vary a lot between different vaporizers and strains of herb.

    SMELL

    Just like with taste, the smell of your herb after vaping will typically resemble that of burnt popcorn.

    A good way to quickly get familiar with how the smell of your herb changes throughout your vape session is to take a whiff of it after each draw (if possible).

    Each hit you take will slightly change the way the herb smells, and you can sense it going from sweet to spent as you vape through a session.

    Now to take it one step further, if you really want to know how spent your herb is just by smelling it, simply pinch a small amount between your fingers. If it has a "sweet" smell then there's still some good stuff in your herb and you should probably vape it some more. If the odor is bitter or sour then more likely than not the herb is completely spent, and if you try vaping it more it really won't do much for you and it won't be super pleasant.

    CLOUDS

    Also known as vapor production, you can usually use the amount of vapor you're getting as an indicator of how spent your herb is.

    With most vaporizers this is what a typical session looks like:

    First 1-2 draws: Minimal vapor
    Middle 5-10 draws: Good vapor
    Last 2-5 draws: Minimal vapor

    They're not all like this but typically it takes a hit or two for vapor production to really ramp up, and then when you near the end of your session the clouds will start to trail off.

    It's pretty much a no-brainer but if you vape an entire session and then you stop getting good vapor production it's safe to say your herb is spent.

    The way this gets a little tricky is that some vaporizers don't consistently produce large clouds of vapor, so you may get a big hit, followed by a small hit, followed by a big hit. With a unit like this it would be hard to use vapor production as the only indicator of how much you have left.

    Some vapes also seem to produce vapor forever, meaning you have to use the other indicators because vapor production doesn't drop off sharply at the end. However, even though vapor is still being produced you will typically know your herb is spent by the way it looks, tastes and smells.

    Anther great reference for the board's newer members.

    I absolutely agree that different vaporizers will yield slightly different looking AVB. Seems that Volcano "poo" is consistently fairly light (no liquid pad or dosing capsule) with little green flecks that I am convinced are tiny pieces of bud stem with chlorophyll showing green (gotten there during grinding).

    I find that in general, conduction vapes or vapes with extra conduction added (e.g. Mighty with liquid pad on top of load) come out with a darker, more consistent brown and that true conduction vapes can continue to provide wispy but visible vapor for far past the point where anything useful is being extracted. That is, IMO its brown because all chlorophyll has been consumed (which has nothing to do with canabinoids) and the string of wispy draws at the end is just from heating up the matrix of other plant material.

    Of course, I have never paid to have my AVB tested so this is all subjective opinion but my view did arise as a result of my experience of effects, etc while vaping.

    I have often thought that the chase for consistent coffee brown AVB to be a bit misguided as color relates more to the chlorophyll than anything we view as medicine. Dont' get me wrong, I have chased AVB color with the best of them...just don't think that color has a 100% correlation with degree of extraction.

    Thanks for the primer on AVB

    I have been using my ABV from daytime for a nighttime cup of tea. If you have a Keurig, put your ABV in the refillable cup. Open a Lipton tea bag and put the contents on top of the ABV. Brew a 12 oz cup. That baby is ABV infused. I add a ton of sugar. I call it Sweet ABV Tea. (Soon in stores) :} There may be ways to extract more from ABV but this is the easiest and it packs a very strong punch.

    Thanks, Bud!


    Do you also vape while consuming said tea?

    I gotta admit, even tho the thought of what it must taste like makes me kinda shiver and feel a little nauseous... I still want to try it...

    It would be very interesting to know, how much thc ist left in avb..also from different vapes. There must be some investigations about that...!?

    It tastes like heaven! the tea really takes over, and sugar makes it really good. I have done had my tea and had a vape session, what a head rush! Awesome I prefer the tea before I go to sleep. I hope you try it and like it.

    I think the Keurig is the important part, because that thing really brews shit really well.

    Bruce did you have to buy that refillable Keurig cup or did it come with the machine I have a Keurig machine but I'm not sure if I got one of those

    Can I break open a new one and use it or is it much different than the standard cups

    Darn I wish I didn't throw away all my AVB I just got so mad last night and fed up with everything.... but making avb is easy from what I understand ... I just need BVB

    How much ABV do you add in the K Cup? 2 or 3 MV-1 crucibles worth? Or ?

    In the process of buying my first vape device. What is the purpose of listing volts, ohms, watts, and temperature?
    Thanks

    Has anyone made a tincture or butter/oil from ABV?
    I'm thinking the tincture would be simple and work fast (I'm looking for medical effects for pain & anxiety)
    Anyone with experience and/or a good recipe?

    Hey tinctures are great. Simple version...

    Cover AVB with the strongest alchohol you can find, preferably Everclear. We use mason jars. Just cover the AVB about .25" above the ABV line. Store in a cool, dry place, shaking it everytime you think about it. Let sit for as long as you can. We usually store for a few weeks though this seems to be overkill.

    Strain through a few coffee filters. Pick up some eyedropper bottles, work perfectly. Drops under the tongue work faster. Drops in beverages are super stealthy. Try only a few drops first to get a feel for how strong it is. If it needs to be stronger, evaporate it by 1/3rd and try again.

    Awesome. Picking up some Everclear today!

    Thanks

    Screw it, I have a mason jar with some homemade everclear and a mason jar full of avb, neither of which were probably ever gonna get used... I’m gonna try it right now..!

    if you want some stronger stuff, barely cover the ABV.

    I had some moonshine once had no clue what to do with it finally just threw it out. Now I wish I still had it.

    Edit: I have never tried reclaim but if the alcohol can dissolve it, sure why not? Especially if you're not going to use it.

    I evaporated this baby down to only needing about four drops for really good feeling while out and about....

    Cool... it keeps sucking up the booze, like my buddies, I mean, a sponge... looks like mud.


    “Hey, you got your Everclear in my ABV!”

    “No, you got your ABV in my Everclear!”

    “Oh well.....!”

    Yeah, , it's a muddy mess. You can soak the ABV ice water, using cheese cloth a bunch of times to remove the black but I'm not looking for Green Dragon, just the effect.

    Fair warning, 1 person out of 8 tried sublingual and she said a red blister appeared (like a burn) and won't do that again.
  • Rockytdogg

    Meh, I don’t care what it looks like... thanks tho.

    Green Dragon? Funny you say that, that was some of the better indica I’ve purchased recently...:

    I decided to melt all my reclaim separately in everclear, then I’ll dump it in when it’s mostly dissolved.
