    Great article, thank you. I have long wondered who complete decarboxylation is when smoking dried plant material, so I found this particularly interesting: "Furthermore, lab analysis of this decarboxylation reaction provides estimates that smoking cannabis yields approximately a 30% conversion of THCA to active THC." I've been playing around for close to a decade with extended dry aging in jars monitored with humidistats. I've come to the conclusion that peak potency is reached at around six to eight months from harvest. I've taken to making my hash oil (cold isopropyl extraction) at month eight for best potency. Since the chlorophyll has mostly broken down at this point, I can do longer soak times than is usually recommended.

    I noticed the testing info in here and thought it may be somewhat appropriate to ask in here if you could provide any help with Abs/Conc. data to help me build the calibration tables for my new and 1st spectrometer, sm1100 case anyone's interested, I can only find molar absorbtion and wavelengths, any help???

    Given that there were about 10000mg THCA in kief (rough estimate for 33g of 200micron), how much was captured in the final solution and did you test or weigh the filtrate?

    Excellent information. Did I understand correctly? IF injesting a juiced form of fresh plant material your metabolites will not show a positive on the drug tests currently being used? You did not comment directly on this aspect, I realize. This would be a plus for those in industry ( e.g.. railroaders) who are subject to testing. Getting the benefits without impairment is a major plus. I was forced to use anti-inflammatories (for osteo-arthritis) while on the job and my stomach is compromised. This type of insight has huge implications for the workplace. Thanks for a well written and documented piece.

      Hi Blake: While the fresh cannabis plant contains more THCA than THC, it DOES contain some THC, which can convert into the form that most drug tests screen for after ingestion. Whether it is in an amount detectable by these tests depends both on the sensitivity of the test, and the frequency and dose of the ingestion of the fresh plant. More research is needed. In the meantime, I'd recommend that consumers of the fresh leaf juice or cold extractions experiment with home urine testing kits. Dr. Kate

    Thank you for all the great information. I have recently done some experiments with extraction processes, and found that using a dry ice extraction first to produce hash, then using a BHO or alcohol extraction to process the hash works great, especially if you have fairly large amounts of trim to start with. I typically see about 15-20% by weight of hash compared to the trim (small buds mostly). A closed loop BHO (the only sane method in my opinion) will yield about 50% by weight going from hash to wax.

    GW, I love this site. Best place on the Web to receive a free education. One thing I can not seem to understand is the use of a recovery pump such as the appion g5. These pumps and lines are not food grade and have been shown to contaminate. Am I missing something? I'm looking for a suitable recovery pump for the rask...rated for flammable gases and using food grade parts. Any thoughts?

    Question. Why would you install a ignition source,(electric heating coil), when Thermal conduction(hot water bath) would work? Why install a component, that may lead to catastrophic failure/explosion for the novice or the not thinking tech? Glacier Tanks, are Building for me a sealed jacketed, water bath. Will be able to circulate water at any temp, against 98% of collection vessel. Plus, no hot spots! ........just a thought.

    The Bink's paint pot, what model goes to 120/psi in the 2 gallon stainless range? Is the Bink's 183S-200 right? The manual says its rated at 110/psi max. Thanks!

        Is that just the latest and greatest upgrade? In your blog you mentioned this comment: "I picked up a 2 1/2 gallon Bink’s stainless ASTME paint pot, rated at 120 psi" Was that an older prototype that had issues and needed to be doubled or something? Thanks!

          Sorry, my error. Old age and too many things and too much time. I had to go dig out the records to see what the correct numbers are. We used the 2.8 gallon 183S stainless pot, which is rated at 110psi and I corrected the incorrect blog number. Normal operating pressure is under 50 psi, and I've never seen one over 80 psi in extreme conditions, so it is well within its certified range. We did have a problem with the bottom drain leaking on the first one that we bought, and the plug was galled in place, so we couldn't tighten it or remove it. Binks immediately replaced the tank, but you might make sure that you can remove that plug before you leave the store, so that you can tighten it as necessary using Neverseize to prevent galling.

    I have a bhogart 2.5 system which appears to be the exact same as the terpenator. I am having issues understanding this thing. I cant even seem to get the vac pump going right to get the air out and load butane. Frustrated and willing to pay $100 for someone local in Portland to come over for a couple hours and show me from start to finish how to use this thing so I can stop starring at it and actually use it.

    What if you want to make your own BHO and reclaim your butane, but don’t have the money to assemble a Terpenator? See: http://skunkpharmresearch.com/projects/ That's how I came to this page. So am I understanding this correct? I need to purchase a paint pot, fit it with hand operated valves,a recovery tank, and order the parts for a column. Then I will have a cheaper version of the lil terp? BTW...Thank You! I have successfully been pulling bho extractions and winterizing with all your helpfull info.

      The Mk I, II, and III are Terpenators, not a Lil Terp. They all use recovery pumps, while the Lil Terp uses heat and cold. Check http://skunkpharmresearch.com/passive-butane-extractor-and-reclaimer/ for how to build a Lil Terp.

    hey gw - so i've been suspecting my system is losing butane from somewhere, as for the past few weeks i seem to have to add a can of butane for every column i run, i.e. i added 3 cases of lucienne to a fresh recovery tank and ran about 30 columns before needing to add more. added 2more cases, ran about 20-25 columns and ran out, then added 1 case and got about 10 columns before running out again. my actual terpenator has a very small leak at the top compression fitting, but not enough to lose that much butane. i never smelled butane leaking from anywhere until today when i was adding more butane to the system, i could smell some coming off of the front of the appion; also, the air that was blowing from there was hot, which it usually is not. does this sound like it needs the rebuild kit, or a different issue? the appion has also seemed to run a little louder/more rough in thes past few weeks as well. thanks!

    1. skunkpharmresearch

      I use 100 psi air pressure and soapy water on our systems to detect leaks. To test to see if the Appion needs to be rebuilt, close the discharge valve and open the intake valve before turning on. It should pump up to around 500 psi pressure and then shut off. It should also hold that pressure without cycling.

    hey grey wolf hope all is well. So i have 4 extractors going like double kindness and they are ripping it up. had some problems with sappy extracts but that issue has resolved itself. today the appion g5 five started knocking a little and then started making all kinds of crazy noise so i shut it off. i saw the rebuild kit at century tools for $230 . i guess i should disassemble and see what needs to be replaced. i presume these motors are like a four stroke dirtbike motor. Valves, piston, cylinder etc

    Reply
    1. skunkpharmresearch

      Knocking may be a different issue. The $230 rebuild kit is just valves and seals for the upper end. It is a dirt simple system, with the two piston rods moving back and forth and poppet valves maintaining the vacuum.

        after some investigation it was discovered the gearbox crapped out . $105 from century tool. yeah the pump rips. where can i get some safety head/ruptures discs for this system. it seems like a good safety feature thanks for the help

        Reply
            1. skunkpharmresearch

              A rupture disc is a metal disc that bursts at a given pressure, used in lieu of a pressure relief valve, because the system sees both pressure and vacuum. It is a safety device to guard against over pressurization to the point of something breaking. The weakest point on the Terpenators is the lid, which is rated at 120 PSI on the Mk IA &Mk II's, and 150 psi on the Mk IIIA. To be rated at 150 PSI means that the failure is somewhere three X of that pressure. The valves are rated at 1000 psi and the hoses at 800 psi, with a 3000 psi burst. They typically operate under 50 psi. I only added the rupture disc to the Mk II, because it is automated and has no one there to monitor the pressure gauge. If it ruptures, it vents the butane outside of the building that houses the exhaust cabinet that the system runs in, so that there is never a combustible level of butane in the cabinet or building. They can also be a bad thing, in that you have to change them regularly, or the constant oil canning from both vacuum and pressure, results in high cyclic fatigue.

      It will make anything from carboxylic acid shatter, to partially decarboxylated oil, depending on how hot you run the hot water bath. It takes about 75F to just keep up with the refrigeration of boiling butane under vacuum, but you can cut the time in at least half, by running the pot up to 212F. I sent you two pictures to your address, one showing raw oleoresin shatter and one thin film AA shatter. Both extracted using a Terpenator. GW

    You need to use a desiccant filter dryer when reclaiming vapor, you want to get one of the larger sized ones with a sight glass after it that indicates moisture content so you know when to swap it out, you can build a refillable one with a 12" tri clamp spool with appropriately sized npt adapter ends and npt to flare fittings. If you elect to build your own refillable / reusable filter fill it with combination of watcom filters at the ends and activated alumina beads followed by activated charcoal and zeolite, just make sure to have at least a few layers of 5 micron filter paper packing between layers and before inlets and outlets ifyou build your own filter, this will prevent water pickup from the material your processing, it also is beneficial to use a hygrometer to insure your material is as dry as possible before processing if you want shatter / thick sap consistency,.. Honey comb is what happens if you don't get all the butane out, you need to thin film purge it between 115 and 145f and preferably have a sight glass on your evap / vacuum back off chamber .
