    URGENT Have you vaped moldy weed?

    Presuming you've gotten rid of the visible white bubbles (fungal colonies) and the mold was on the surface (not burrowed extensively under the surface, throughout buds), simply 'sterilize' or kill all living fungi and other microorganisms by heat (also drying the material and activating THC) --...

    Log vape resistors - My DIY Log Vape

    Yes, as I noted before (above), consider using a heavier-duty resistor, such as in the 7.5-8 ohm range. Perhaps, look for something like Ohmite 35J7R5 (high-energy, wire wound), ideally RoHS compliant (presuming you will be powering this with either a variable power supply or some type of...

    Log vape resistors - My DIY Log Vape

    I suggest considering resistors in the 7.5-8 ohm range. At 12-14 volts, this puts out up to 26 watts, giving you ample power for whatever heater/exchanger you design, while drawing up to 1.9 amps, no problem for a common brick-style 12-14 volt, 3-4 amp, regulated power supply/adapter or any...

    History of Log Vapes?

    I recall the history of log vapes has been discussed in FC, and in the Vaporpedia. To go back to the some of the roots, search for terms such as "Bob," "Eterra," "patent," "log," "Flash Evaporator." www.flashevap.com gets you directly to the source, with some buried historical references...

    Homemade Vaporizers

    I hope they work for you and I am wrong, but I doubt any flexible silicone-encased heater will work for vaporizers. I don't think they have the heat/power per surface area you need. I think you'll have to be running it full blast, and even then, it may not get things hot enough. Yes, the...

    Where to buy black silicone tubing?

    I doubt that there is a real-world market for black opaque-colored silicone tubing; and if there were black silicone, you may not want to use it. The commercial selling points for silicone are that it is transparent, so connections and flow can be readily confirmed; flexible (due to the normal...

    Can decarboxylated "fresh" weed get more potency as it ages?

    Yes, it will get more potent (active agents/weight) as it 'cures,' if only from evaporation of more water and some of the more volatile (lower vaporization temp.) aromatics.

    I think I'm done with oils/waxes/shatter etc.

    I have no familiarity with modern butane-extracted products. I recall honey and red oils oils that were made by classic ether (diethyl ether) or n-hexane 2-phase (with water) solvent extractions, starting with hash. How does this butane extraction compare to ether extraction?

    Sublimation

    A major problem with much discussion, originating from the manufacturer and continuing with others, including now being further disseminated by vendors, goes beyond the simply totally wrong terminology (and fraudulent claims, when marketing hype is parsed for meaning), and extends to the core...

    How Long Will Herb Keep in Dry but HOT Environment, in Glass?

    No matter how hot it is or where you are, even in a desert, if you bury it, that should provide a cooler environment. And it would be well hidden too.

    Discontinued The Sublimator

    Yes, its seems that, "Sublimation or not, in our opinion there is a lot more going on here than just vaporization." Careful optimization of air flow and aerosol particle size (re)formation may be advances here. First, I presume everyone is aware that only the very smallest particles (of...

    Which vape has smallest trench/herb receptacle plus high temps?

    Log-style vaporizers, particularly with a variable power supply, could qualify for "smallest trench/herb receptacle plus high temperatures." These are even 1-hit usable - as small as you want to get.

    Sublimator

    Perhaps, thermal desorption is what this use of 'sublimation' refers to. Thermal desorption refers to (simplistically) high heat causing detachment and ultimately vaporization of molecules adhering/sticking to a solid substrate, such as plant material (cellulose). In this view, vaporization of...

    coughing with different vapes what might be?

    I can't provide "proof" that denser vapor = larger particles vs. denser vapor being just more particles. Talking at this level of aerosol science is well beyond me. But I can use an analogy of, other factors being equal, longer-condensed (or cooler) vapor will appear denser. Water vapor (in...

    coughing with different vapes what might be?

    I would presume that the size distribution of vapor particles/droplets/condensates, which start to form instantly with these sticky herbal resins, also is a factor contributing to coughing. I would presume that vapor at the same temperature but with larger particles (e.g., looking denser) will...

    A portable vape close to a rockzap?

    For those who crave going wireless/cordless (at least in terms of use) with their log vaporizers, this is really ancient, legacy technology! The Flash Evaporator was commercialized around early-mid 1990s by 'Bob' before he brought out the Eterra (and got a related broad patent), the...

    Heat Stream Lighter Ideas

    Do a search and check out "SMD Hot Air Rework Stations." With variable temperature, air speed and/or different nozzles, etc. these should be able to well replicate the lighter-type device functionality you seek. The constant hot air stream should be much the same as a pressurized gas flame. Has...

    Can Pot Treat Cancer Without The Devastating Effects of Chemotherapy?

    Can Pot Treat Cancer Without The Devastating Effects of Chemotherapy?

    I qualified my "no" as a simple (yes/not-type) answer to the basic question -- "Can Pot Treat Cancer?" I presume everyone agrees it lacks "The Devastating Effects of Chemotherapy," the second part of the question. Would you answer 'yes?' If so, can Cannabis cure cancer, what types and with...
