    I can more then likely keep it below 60 since I am in the desert. I need to get a new meter, I don't think the old spring one is acculturate on the humidity. It amazes me that my thermometer with the humidity gauge usually reads around 40 but outside it can be 10 so it leads me to wonder what is bringing the humidity up in the house. It also makes me wonder hmmmmmmmm is it even accurate, my guess is no.

    I'm relying on a cheap chinese thermistor - I've never tried calibrating it.
    I think I need to calibrate and poke an industrial one in my herb like http://fuckcombustion.com/members/hippie-dickie.924/


    Few sane people will let you get at those receptors inside their heads since it generally involves making holes. OTOH, given resources and care, it's not all that hard to measure some downstream effects without holes. Crude but measurable manifestations of whatever the vapour does using some kind of standard measurement...

    Woodwind player so likely above average control. I use a flashlight to see what's coming out of the herb if I'm not seeing vapour coming out.

    Smoky, tart, acrid, sour, edgy taste completely dominating all those pine clear terpene flavours I enjoy at lower temperatures.
    It did not feel good.

    It sounds like your herb is too dry. Get you some boveda packs, and this should solve your problem. Make sure you break up your bud first before storing it with the boveda. Also, to get all the flavor from your herb to last a while, for those times when you just want to sit back and enjoy all the different subtle flavors, start low(around 220f) then raise the temperature with each puff until you hit 396f-410f. When the vapor gets thins at the high temperature, stir your bowl and extract the rest of the cannabinoids. Peace.

    ^^^Vaping @ higher temps does give the popcorn taste. I actually like it but YMMV. As long as your ABV isn't burned after the session I guess you're not combusting. An that never happens with the volcano on 9(226°C). I hardly vape fresh herbs on 9 tho. I almost always go up in temp to finish at 9. It seems to benefit the effects as well as the taste.

    A little of topic but still.

    I am lookin for a portable vape wich can give me the temp control I have with my volcano. I'm looking into the inhalater (xp) will this do the job?

    Dreamer, not directing this at you personally, but as I was reading through the whole forum for the first time (having spent a couple of weeks on pages 1 and 2), the temp stuff was an epiphany for me. It changed my entire vaping experience and my health has improved. So I expected to go to the end of the post and find people talking about vaping at low through hi temps, not going to the middle and wasting the bottom HALF of the cannabinoids.

    I read all these posts by different folks, and I wonder if any of you is a medical user, or if you just don't get the first page of this post! I read about those of you vapers starting off at medium to high temps, and I am confused as to how ANYONE who's read this entire set of posts could START vaping their mmj at such high temps. Do you just not get the concept of starting at a very low temperature to get the anti-inflammatories and the anti-spasmodic effects? Those compounds are destroyed by starting out at 180 or 190c! What Tom said on page ONE is that whatever temp you START at destroys ANYTHING below that temp! If you start off like the stoners do, at the thc "sweet spot" as it's known by some, you surrender ALL the low temp cannabinoids to the sky. They're GONE. ALL GONE. Might as well be combusting it! I'm a medical user, and I start at 130c, vape 3 or 4 BOWLS full off the same stuff (try it before you poop on me, just give it a try -- I'm using a Volcano digital, sorry if you can't afford one, but any digital product should work more or less the same)! I can get a dozen balloons off the same half gram just by starting low. No, I don't get high at 130 or 145 or 160, but I do get a LOT of medical relief! It's all on the chart on page 1! And some other copies of the chart that have been updated over the four years since it came out... Tom started his chart at 140c, but I found several versions of his and other people's work (including a 3 part article at The Weedist that lists all the compounds...). The bottom line is that a whole bunch of cannabinoids are released at the 125-130c point. I personally get a lot of mental clarity and energy from 130 and 145c especially. At 160, I start getting a bit high. Those are my three low temps. I put the ABV into a jar marked medium if I don't want more. I also have a low jar and a high jar. Anything vaped in a pen item goes into the low jar (operative temps in many vape pens is about 125-130, so far as I can tell). Anything vaped up to 160 goes in the middle jar to be vaped at 175 and 190 for thc and body high. The remaining abv goes into the high jar, which I vape at 205 and 220c. Those are my three layers of vaping, and my temps at each. If I hurt and need physical help, I go to the middle jar. If I need sedation, I go to the high jar. I don't START with fresh stuff! That would waste all the lower compounds! For daily aches and pains and not eating oxycodone like m&ms, I vape low temps. I got it all off this post, and verified it back to 1984 with HIS sources, and found a few of my own that say the same. I'm getting results that let me cut back on my foundational pain opiate, and let me do more stuff every day.

    Check my blog vaping4life.wordpress.com for more info on my system, but "my" system comes from this very forum! I suggest every reader give lower temps and re-claiming abv and lightly vaped materials a serious try. Especially if you're a medical patient and you are even slightly concerned about money. I no longer worry about running out of meds! I have a steady supply, and once it's been through the vape train? It goes to the kitchen. I cook with the abv from the high jar. And when it's sitting in an oven at 350f cooking in brownies? All the rest of the cannabinoids (the last 30%, some say) go into those foods, the brownies and the pesto and the other items I add mmj to.

    Seriously, guys, STARTING your vaping cycle in the middle of the temps that way is wasteful and illogical in the face of reproducible scientific fact about cannabinoids and the various temps at which they are released. It's not a matter of opinion. It's a matter of temperature. Any indica at 130 will wake you up and make you dance better than Jack Herer at 180! It's about what gets released at what temperature on YOUR vaporizer with YOUR stash IF it's ground correctly. I was pretty shocked to get the temp thing, myself, so I know it's counterintuitive. But it's a fact, and it's reproducible. Just try it.

    I challenge you to go back and reread the whole forum, and to examine the thinking further on this "temp ladder" philosophy of mmj vaping. Try shifting your perspective away from the THC part of the plant and focus more on the entire spectra of the cannabinoid line-up: there are an unknown number of cannabinoids, and they all are released at different temperatures. I believe you will experience a huge difference in your medication usage, cost, and effects. I certainly have, and it is 100% due to what I have read in the beginning of THIS forum.

    Not trying to start a flame war, pardon the pun, just trying to make a point back here that i thought got made up front, but I don't see anybody back here talking about the main point of this particular thread: how vaping at different temperatures releases or destroys, as the case may be, different cannabinoids. JMO, but Tom seemed like a pretty damned smart guy to me, and I found his research to be compelling and accurate, and his results work on ME. They also have worked for everyone that I've shared them with through my blogs. I'd love to hear more about what results OTHERS have had with true low temp vaping: sub 160/300ish temps! Down where all the truly good anti-you-name-it's are!


    imho, no portable is gonna give you the temp control of a volcano... that said, there are a lot of portables out there to choose from. I find the pen vapes to be a lot of fun, but they really only give flavor and very low temps (lots of anti-inflamm activity, v

    Luchiano, the boveda packs will help you KEEP your herbs frresh, but from EVERYTHING I have read, the drier your herb, the better it vapes. WET herb will NOT vape well. You do NOT get vapor out of wet herb. It's counterintuitive, not what you THINK ought to be, but it's true. The oils aren't water soluble. Keeping herb moist just keeps the trichomes from falling off and becoming kief. I mean, first I learned to keep my herb moist so it didn't crumble and burn in the pipe, and once I got that all set up, bovedas in every jar, then I get a vaporizer, and have to change everything all over again! This whole process has been one epiphany after another! But seriously, wet herb don't vape. It steams. You get water, but very little herb. It should be left out for ten minutes to dry after being ground upside down in your grinder (leaving it upside down means the herb is in the teeth the whole time of grinding and it gets ground more finely without turning into powder--if you invert the grinder without opening it before taking your herb out, the loose kief falls through the bottom screen and stays for your later pleasure...); try it and see. btw, there IS no visible vapor to speak of at lower temps. There's taste, and there's plenty of cannabinoids, but there's no "smoke" to speak of. There's very little in the way of visible smoke until the 160 area, when vapor begins to be visible. At 190, it's milky. But at 130, 145 and 160 (my low temps), there is very little visible vapor. Just taste. And omg what a taste...

    @Qatmaster: your step-ladder approach is a good one but you have made an incorrect assumption. Starting to vapourize at mid-temperatures does not mean that the compounds released at lower temperatures are destroyed or unavailable. Higher temperatures simply mean that all compounds that are volatile up to the selected temperature are released together. Because the active components interact, the effects of combining them is not the same. You can achieve different results by starting at 180°C than you will if you start at 150°C and step up to 180°C.

    Please be careful about using the temperature charts. The temperatures listed are not binary, i.e. a particular component is not released only at the listed temperature. All components start vapourizing well below their listed temperatures. At mid-temperatures you will still get some high temperature compounds, but not as much. You cannot select a component just by using its specified boiling point. The best you can do is influence the ratio of that component to others.

    Consider also that none of the components exist independently, they are contained in a matrix. This changes the behaviour somewhat and there is no research I'm aware of to determine exactly how. The temperatures at which various components boil are specific for that compound alone, and do not take into account the energy required to break up the matrix.

    You are not just vaping oils, you are vaping other compounds that boil at lower temperatures. The moisture also helps prevent quick degradation of the lower boiling oils within the herb since water helps keep the temperature stable when you use high temperatures around 230f degees and up. You will get constant flavor this way. You also are protecting your respiratory system from drying out over time. When everything is dry, you will lose some moisture in your system from the excess air and for some this may cause problems since the older people get the drier they tend to become.

    Moisture when vaping is something that isn't for everyone. Some people just want a quick experience and dry herb is best for that. Some people just want to sit back, slowy enjoy the flavors, and have total smoothness. Some want that experience wih no clouds for more absorption, while going through the whole range of temperatures such as 152f-446/448f, in 2-5 degree increments because we want to get as much of an effect we can get, which clouds wont do. I'm in this class. If you dont want moisture more power to you, I want it because I want a nice moistened respiratory system, and I want little to no degradation of my substances from the high heat.

    I'm with you on the vaping at low temps thing, as well as the amazing array of compounds which are released at different temps. I do set temps, based on what is theoretically released in that temp range: 130c, 145, 160, 175, 190, 205 and 220, if I ever go that high -- since I both revape and reclaim my abv, I don't consider the unused compounds a loss, more of a transfer in time, something that gets turned into medibles or hash oil later on. I base those temps on Tdavie's chart and some others like it that have decent cites. I've had medical improvement, so it seems to be working for me at this point. Do you really go up by 2 and 3 degrees? How many balloons/sessions do you do on a sample of herb?

    And as for wet/moisture v. dry, I'm unclear on the overall logic. I've seen both arguments, but where I've landed so far is: AT THE TIME OF VAPING, one should have very dry herb. UP TO that time, it's best kept moist. Now, I didn't think it could make much difference. But I HAVE found that vaping drier herb produces more flavors and taste than vaping wet herb. I don't mean sticky wet, I just mean fresh ground wet. From the container with bovedas in them to the grinder to the vaporizer just doesn't seem to be as good as from the container with bovedas to the tin container that's air-tight-ish for what will be used that day, and from that tin container to the grinder to a plate for ten minutes after grinding before vaping. That upped my yield of numbers of balloons, that luscious taste factor and my personal health factor... I don't know why exactly this is so, but it seems to be so. Is that so for you?

    I deal with the moisture "problem" with a rule: vape one, drink one. I got all dehydrated when I first started sucking on pens... Once I realized I was having a problem with dehydration, I addressed it right away and all was well. But MAN did I get dry at first! So, vape one drink one became a motto... I use a Volcano, so I'm getting about all one CAN get from vaping but I'm only about three months INTO my vaping career! I was a happy combuster up until that first taste of unburnt cannabis! Then I was a happy vaper! I'm quite interested in being schooled on the finer points, however! Please do share!

    I believe that the lower temp cannabinoids get "lost" when there is conduction present between hits, and the longer the session, from first to final draw, the more it changes the initial cannabinoid profile as they progressively oxidate like THC to CBN.
    This explains why people report better extractions (in terms of psychoactive and medical effects) in vaporizers like the Herbalizer where you have accurate temperature and negligible conduction coupled with a powerfull element.
    It also explains the number of tasty hits which correlates with the presence of lower temp terpenes.

    I don't believe a sequential temperature vaporization is more efficient than a max temperature vaporization, this is more accurate the more convection each vaporizer employs.

    The benefits of a sequential vaporization is precisely what tdavie did: choose the temperature that released the cannabinoids he needed, without extracting the unneeded cannabinoids and in the process having two or more different outcomes by using ABV from different temperatures (low temp ABV vs high temp ABV).

    That is a good point about constant heat conduction. It really does release vapour between hits, although the loss due to this will vary by design. If the vapour is released but remains in the air path, the loss is mostly flavour and not active components.

    I mentioned that the compounds exist in a matrix and I'm not aware of research on the implications of this. What I do know is that the compounds interact with each other and this changes the effects. If you use a stepping strategy, you will not achieve the same results as you would by going directly to a specific temperature. The ratios of actives will be different and so also will be the interaction.

    I agree, it does release vapour and the amount that is loss vs assimilated varies with the unit design itself, which is why different degrees of conduction don't correlate directly to its efficiency. There are conduction designs that work better than others.

    BUT, if you think that conduction designs usually get gunked up quicker and smell more, does that not imply a higher degree of terpene and cannabinoids being deposited after conduction extraction?
    From my user experience, the units with more convection vs conduction stay cleaner for longer and release less smell between hits and while it is warming up.


    The ratios will be more different if there is conduction present and even more if the session lasts longer. I think part of the headier high caracteristic of faster sessions is partly explained by the less percentage of THC that oxidated into CBN which is sedative and counteracts the THC's efects.

    In theory, for a full convection unit, there should not be any difference from a stepping strategy vs a one-two hit session.

    I agree with you except for that theoretical conclusion. I am probably not explaining myself clearly. The effects will be different because you will not experience the same ratios of active components, and the interactions between them will therefor vary.

    As to the higher degree of deposits, I think that in any given session the quantity involved is not noticeable, but over time this build-up definitely starts to affect flavour and odour.

    I think the reason you 're seeing a difference in the two storing methods is because when you just go straight to the grinder from the boveda, you will have more moisture in your herb which means less of a grind, then if you let some moisture go away. Less grind means less extraction. You will also get a quicker extraction because water keeps the temperature from raising quickly, then dry would.What I do is just grind the herb before storing in the boveda jar or just regrind the herb after a few puffs at around 300f since it will be much drier.

    As far as starting low and raising the temp in steps, that is best because the lower compounds help your lungs dilate more allowing you to take in more cannabinoids when you go higher in temperature. If you were to start out at a higher temperature, you will get less of this effect from these substance because you are bringing in everything at the same time. I dealt with this in 2012 in a thread on here. Just go through my posts and you should find it.

    I just look at things the way I look at how food is absorbed in the body. The more denser foods are absorbed more slowly then the less dense ones and when you study foods reaction to the body, it makes a lot of sense. Everything should happen in a smooth consistent process to keep the body in a good homeostasis, as well as have a good amount of moisture. Think about it when food is dry, you are pulling away moisture needed for other parts of your body to help keep your intestines working and from drying out, therefore knocking your body out of whack. I have a theory eating too much food low in moisture causes health problems.

    Anyway, this method has helped me achieve effects most never feel. Its a creeper effect so it catches people off guard but when it hits, they are in awe because it goes against all the rules of the smoking world. You dont see any vapor, its smooth and cool, and you are relaxed with no sense of irritation, yet you are more higher then you have ever been and it can keep going meaning the ceiling just keeps climbing but instead of just "high" in the head, you feel it with the sense of touch and it last long. I think the reason you really feel it with the skin is because the skin is a much larger organ than the brain, so it has more receptor sites for the cannabinoids. Sex is amazing when you just keep packing bowls and do the method I described. It may take longer then doing a fast hit but it is way worth it,

    This absolutely works, as long as your base product can support the effect you're looking for!

    Examples,

    A heavy indica will never really give you a full blown UP effect, like with a sativa, but you can definitely choose to extract in the lower temp range to avoid receiving the heavy sedation goodies. Then, you can vape the product again, later, and get the benefit of the sedative compounds.

    Or, a full blown sativa vaped at high temps won't be able to provide the same sedation as an indica, because it just doesn't have the compounds...

    So, you can definitely tailor your effects within the range of the product which you are extracting.

    Vape On!

    I think i agree with you, why do you say the ratios of active components will be different? Do you believe that "ladder extraction" will influence the concentration of each cannabinoid or is it what luchiano said about some giving you a better assimilation of the ones to come afterwards?

    I think it affects more from the start but i don't have a way to measure it. I said this because the high is more sedative which i attribute to the thc oxidation into cbn but also because the taste goes out very quick.

    Just gotta say I disagree and why. This is not to start an argument, but to create a distinction. I can take a heavy indica, vape it at 130c and get a delicious UP high for several hours. At 130c degrees, only certain compounds are released, and they are NOT the heavy parts of the indica. They are the lightest most sensitive flavors, and they are GONE GONE GONE if a person just GOES to a temp like 190c and fires up! Anything below about 185 is transformed into something else by the heat or is simply destroyed by the heat. This is true whether I leave the herb chamber on the Volcano or take it off the Volcano. This seems to me to be completely logical, and I don't get why it's not blindingly obvious to others as well.

    The stepping method seems to be completely superior to ANY given temp, because, as a medical user, I want every level of cannabinoid I can get. In my experience (ok, maybe it's only a couple o months with a Volcano, but it's a solid two months of steady experimentation with both sativa and indica varieties of medical calibre, ground properly and finely, with no excess moisture nor excess dryness in my herbs. I feel pretty damned confident in my logic and my process, but I don't see others' comments reflecting my experience. That's somewhat confusing. I'm not looking for other people to validate my experience, I'm looking for a solid body of evidence that mirrors my experience.

    I have RSD/CRPS, TMJD, and add on 35 years of various car accidents and trauma causing and caused by the diagnoses, depending on which symptoms we're talking about at a given moment. I'm looking for both pain relief and a sense of wellbeing. I've been getting that, since I began using the stair-step method of using at 130c,145c, 160c, 175c, 190c, 205c and 220c. At each of those temps are a large number of different anti-substances and pro-substances. Look at 140ish, 155-160ish and 180-190c as examples on Tdavie's chart (just as one example of a reference) Those temps are closest to the largest numbers of terpene and terpenoid and cannabinoid substances in the plant. By methodically applying those temps and the resulting vapors to myself, I achieve a delicious long lasting sense of well being that improves as I "step up the ladder" of vaporization. I understand YMMV, but I'm using a top of the line Volcano digital vaporizer as my "vehicle" and my mileage is FINE. Why is it my experiences are not reflected here? Am I missing something, or is it just that some folks do not care what gets destroyed so long as they get THEIR particular methods and temps to work? Am I more sensitive due to my physical condition, thus I perceive this pattern and I get MY needs met? Bottom line, am I missing something or am I leaving something of value behind? I don't think I am. but I'm also only 2-3 mnths in, and thus I cannot stop learning and say I know enugh now, forget the discrepancies -- I know what I know nd thus I don't need to learn... bogus thinking for sure. Feedback, anyone?

    Everything you posted, is damn near the same for what I posted except for moisture. If you read my post again you can see I said stepping up in temps is better then picking one temp because there is less degradation, the same you're saying. The only thing we disagree on is moisture from boveda packs.

    A tip that will help extract more vapor quicker leaving less substances behind if your herb isnt completely dry is to regrind the herb after a few rips. When herb has very little moisture it grinds to an almost powder like substance but since you have a volcano, it may not be good since the screen you have may not be tight enough to prevent herb from falling down thhe screen or flying into the bag. Storz&bickels sell tighter screens so you may want to look into that.

    Absolutely agree :tup:.... wasn't the meaning of my previous posting... just meant that if your product doesn't have IT in there to begin with, no amount of temperature change is going to add IT. (IT = the cannabinoids that contribute to the effect being sought)

    (If that were the case, strains would become a bit less important, as one could just dial in any effect based on temperature they chose...)

    We know that the active components of cannabis interact with one another. We don't know much about how. @luchiano's theory might be true but nobody knows. The only paper I know of about this is Cannabis and Cannabis Extracts: Greater Than the Sum of Their Parts? by McPartland & Russo.

    The ratios are different because the ratio will change the longer you spend at a specific temperature. Eventually you will vapourize all the components that boil at that temperature and below, and you will increase the proportion of components that have boiling points higher than the selected temperature. Think about heating water. Notice that vapour starts to appear from water at around half the boiling point. As the temperature approaches the boiling point, you get increased amounts of steam. This is happening to the components listed in the famous charts we've all seen, but people often think that vapourization is binary, e.g. nothing at 159°C, then everything at 160°C.

    I'm glad you've found ways that work for you. Your understanding, however, is flawed. You keep insisting that components are destroyed when you select a higher temperature. This is incorrect. Everything is still there in the mix. Furthermore, you are getting some of the higher temperature components, just not as much.

    If it worked the way you think it does then combustion would be a complete bust, because the components would be destroyed by the high heat.

    @pakalolo everything isn't in the mix because you do lose some of the lower boiling components because they degrade when you go too far past their boiling points. Some boil as low as room temperature, so if you start at 390f, you will destroy damn near all of those substances. This will happen fast when using a vaporizer where the bowl is always in contact with heat. This a major reasson why smoking has so much less active substances then vaping or ingestion. Now, the heat isn't killing everything because the plant fibers are good at keeping cool, so unless yoh apply direct heat over herb that is spreaded out wide, some lower components will boil with not much degradation due to the temperature not being as hot in the middle of the herb as it would be on the surface. The thing is for this to happen you need to use a packed bowl and this brings a lot of condensation or clouds. For me that is not what Iwant. This is why a good vaporizer is such a blessing, you can vape damn near everything without a lot of condensation, if you have any at all, and you get no degradation of anything.

    Remember all of this is alleged

    what reason do we have to believe that the active compounds with lower boiling points are destroyed by being exposed to more moderate temps like 175-185*C?

    I don't think it's reasonable to compare heating cannabinoids past their boiling point to what happens when they come into contact with open flame. I've read that the hottest part of the flame created by a butane lighter approaches 2000*C...

    Of course the components are destroyed if they are heated to high enough temperatures. The assumption @Qatmaster makes and you seem to agree with is that the range of temperatures used in vapourizing is high enough to destroy active components. There is no evidence to support this and it flies in the face of how oils in general vapourize and break down. Oils vapourize at their boiling point. They are destroyed at their flash point, which is a much higher temperature.

    @everyone lol, I don't know how I got dragged into this with one comment but I was going to suggest to ask the experts or at least people way more in the know about this as I know nothing. Thanks paka and luchiano.

    I can go now pass out cause there are way to many words on this page for me to comprehend but I did try. The only point I would have made is paka has said many times that vaporization is not an exact number and you can actives at many levels of heat.

    Now I will go nurse my confused head:ugh:

    Dreamer, please keep in mind that relative humidity is not an exact measurement, since it's relative to temperature.

    In your case, 10% RH outside in the much warmer air is probably ~ the same amount of water as 40% RH inside your house, at the cooler temperature. It's just that warmer air can hold MUCH more water than cooler air, hence the lower percentage. RH is just an approximation measurement, whereas dew point is the exact measure.

    Hope that helps.

    That is interesting. I always wanted a weather station and now I want one inside too lol. My phone tells me the dew point and it never changes here cept when the weather really has an extreme. That is very interesting though. I never understood dew points at all till I moved but I still have a long way to go for even a little understanding. Thanks @nicelytoasted :)
