My secret to THC E-Cig PG-Liquid... Potent, Effective, Cheap, Easy!!!

[Happy Jack]

Care to elaborate? I mean I know we don't know exactly what's in the product. But "snake oil" implies that the product doesn't do what it's supposed to.

Just to be completely clear .............. the product works. In my opinion it actually works too well in it's ability to break down and dissolve an extract. This is what concerns me. I've worked with many different diluents over the years and this one here is by far the most caustic I've ever seen. That's not a bad thing mind you but this stuff makes 190 proof organic ethynol look like bath water. Because of that I am questioning what the hell is in it... that's all.

The fact he won't disclose it makes me even more skeptical............. hope you see my concern in this.

These are valid points for sure. The secrecy is disappointing. It def mixes a little "too easy". Although I do still have to apply heat. I haven't been able to mix without some kind of heat source.

Have you tried adding your extract and allowing it to sit at room temp for 24 hours? Worked for me without the use of any additional heat

I've been following this one for a while.. long while actually- but I've got to ask- am I alone in wanting to filter shatter/wax on conversion to juice? I gave it a shot with a bit of puff majic, but ended up unhappy with the amount of particulate matter left in the shatter (dispensary top-shelf in Detroit)
Of course upon attempting filtration.. nothing really happened, it wouldn't flow

Also does anyone know what the puff majic flavoring base is? i had some on my dripper overnight, and took a hit without thinking about the wicks in the morning, and it tasted like my ejuice and shatter, no hint of the puff majic (smooth menthol or w/e the hell it is) as if it had all evaporated out..

 

[VEGASMMJ]

@OttoMan yeah I tried it. I know that's what they claim but i still had to apply heat after 24 hours to get it fully mixed.

@Grim Chiclets I think u might need some better shatter. I use some beautiful golden shatter and my juice turns clear as day no particulate whatsoever. My buddy however buys whatever the cheapest wax is on sale and his juice usually has some specks of stuff in it. Comes down to quality of starting material.

Me too ....... exactly !

The batch that seized up was labeled Ionic (brand) "Ultra Premium CO2 Shatter". It was 1 gram to 1 sample vial of "Blueberry" (.6 ml).

From my experiences over the years ...... the only time I've really run into an abundance of tank "clogging" has been when I tried to dilute shatter. Never an issue with wax and certainly never an issue with goo. I remember several times back in the days when shatter was rare getting my hands on some .......... diluting it down and loading in my pens only to discover that after sitting in the carts for a few days or so ..........the air holes were completely clogged and I ended up tossing out many of them plus lots of returns from customers. Just too damn sticky and I avoid it now completely.

Yeah I kinda assumed that was the problem.. but I've never come across anything better than what I can extract- though I can't do a lot of that at the moment. Ah, well I'm sure I'll get back to it at some point..

Then again I'm the guy in my group of vapor buddies that's infinitely more obsessed with purity/cleanliness than everyone else!

On another note- holy moly wow those terp extracts/mixers are expensive.. first I've seen of them
(it took me like a week to figure out what the hell CC and VE are )

Thanks for the tip. That's good to know.

Weird, complete opposite for me. Shatter has the least plant oils remaining. It fully dissolves in PG/VG and stays that way (in my experience) instead of just emulsifying like the oilier waxier stuff (which then gums up in cold). I've mixed shatter, wax, pull-snap, crumble, and hash oil now. I intentionally only buy shatter now for ease of use compared to the rest (if I'm not pressing my own rosin). I haven't experienced any difference in clogging myself. I did switch to large wick hole burners though, so nothing clogs at all anymore anyway, but I hadn't noticed that in the past. Could be due to mix ratios? I never go under 1:1.

I think Puff Majic went so far as to recommend shatter over any other concentrate exactly because it contains less atty-clogging waxes and particulate. Avoiding shatter doesn't really make sense to me. That having been said I usually go for mid-priced wax because of dispensary deals, and I just prefer the taste/smell. I almost always have extremely clear juice at the end with no visible particulate, though dissolved waxes are still likely reducing my atty life.

I started using a CC mix in my second Melo2. It was a "wow" potency wise but I ended up watering it down with Vapeur Extracts Blueberry for 2 reasons. 1) The potency was too high. Based on the situations I use THC for, I can't be in a position where one hit leaves me unable to drive. 2) the taste. With the Melo2, Titanium coils at .5 ohms, the taste of my CC mix came through VERY clear. But what I really noticed was the pine/air freshener taste of the CC diluent. It isn't a totally unpleasant taste, but I couldn't see myself diluting it more with CC.

The VE Blueberry is ok so far. I didn't add a ton but I'm not getting the burnt PEG taste at this time. My Temp Control setup is working better with the Titanium .5 ohm coils than it did with NiChrome .15 ohm. I'm able to get a more consistent vape without fiddling with the settings. I've also seen some health concerns with using Nickel which aren't present for titanium.

Yeah I'd say it has much to do with the dilution ratios. I never went over 30%.

The issue I had wasn't anything to do with clogging with waxes and particulants. It was likely due to our desire to minimize the diluent so much that it was likely just rehardening somewhat over the air hole after a bit of time.

I'm pretty sure you need to be a bit careful if using CC and shatter as they actually mention on their site that the diluent evaporates after a month or so and the extract will harden.

On topic but slightly different convo, I've been exploring flavoring and wanted to share a resource I've come across. (talking about flavoring your juice by adding concentrated flavors here)

The Vaping Underground forums have an entire section (5 sub-forums) on DIY liquid. Nic needs are different from Cannabis, but anyone curious about DIY juice, and flavoring their juice can get lots of relevant info here. The recipes sub-forum in particular could be useful to people here. If you buy concentrated flavorings to add to your juice, it's hard to estimate how much to put in sometimes! Skimming through some recipes helps give you an understanding for flavor additive ratios. Also, most people on that site use flavors by the same company: FlavorArt (FA). Since different flavors from different companies are different strengths and require different ratios in recipes, it's super helpful when you find recipes that use all one company's flavors!

Also, there's a very enthusiastic and knowledgeable poster over there named HeadInClouds (HIC) who posts lots of great recipes, but also posts notes on each flavor from FlavorArt (taste, strength, suggested mixing ratios, etc). There are a bunch of separate 'notes' threads, but all of those notes on FlavorArt flavors have been compiled on this page for easy reference (with HIC's permission). Very useful if you're thinking of buying any FlavorArt flavors!

Note on FlavorArt: There are many different companies that make concentrated flavors, everyone has their favorite. I've noticed many DIY'rs like FA because they are transparent about what is in their flavors, and proactive about discontinuing flavors if studies show their contents harmful (things like Diacetyl, Acetoin, Acetyl Propionyl, etc).

It all seems a little overwhelming at first, but there's not that much to it. I've ordered and I'm waiting on these flavors right now: blackberry, kiwi, black tea, green tea, lemon, lime, mandarin, pineapple. I think adding subtle amounts of different combos of some of these flavors to the Holy Terp mixers that I already have will make some delicious juice! I'll let you know how it goes and share any recipes that are hits.

**EDIT: I order from gremlindiy.com just because that's what I stumbled across, but there are many other places to order flavoring from all the different companies if you search around.

**EDIT 2: I got a mod note for posting twice in a row in a thread before so I'll just add this here... I'm trying something different this time. My tank was almost done and I wanted to mix a new batch so I dumped the remainders in my old Kanger T3D (with some older remainders from last time). I mixed up a new batch (1/2g OG Kush wax, 16 drops HT Philosopher, 16 drops HT CouchLock, 8 drops lemon concentrate). However, I'm not going to touch it. I'm going to let it steep for a couple of days and just finish the combined remains in my old tank. I've seen from nic flavor recipes that steeping helps with flavor retention. Not expecting much, but I'd like to see if the concentrate's flavor (and the added lemon) persist any longer when I eventually hit that tank.

Holy crap, no doubt. The Denver Terpenes sample packs are twice the price of the exact same sample packs from Extract Consultants.

Buyer beware, search around.


.

As others have answered, yes what EC sells (and Denver Terpenes sells as well, their non 'serum' stuff) is concentrated terpenes to be added to a diluent, not as a mixer on their own (that's why they specify such small add rates, it's the add rate to the mixer diluent, not the add rate to your concentrate). IE: it's not meant to be mixed directly with your concentrate, it's meant to be mixed with some form of ejuice to make a mixer, then mix that with your concentrate. I had emailed them a while ago to verify and they explained that to me. CC's "Solution" and DT's "Serum" have terpenes plus something else (not been revealed yet) as a diluent so they're already a mixer. EC's terpenes and DT's terpenes are just concentrated terpenes (DT's are twice the price of EC's, and DT's "serum" is way more expensive than CC's "solution").

Sorry, if I confused anyone by bringing EC into the picture. I was talking about it with regard to buying terpenes and glycerin/glycol separately to create DIY mixers.

Hi @Terp addict! Welcome to the forum. Do you represent Denver Terpenes?

 

[joeblowssmoke]

Hey everyone, I have an ecig I put together a while ago to vape my shatters and saps. I found a triple quarts coil to be my favorite for this. I'm curious about making ecig juice with my concentrates and was wondering if my atomizer would work with this type of juice. Also, if anyone can point me to a good "recipe" I'd appreciate it. I understand that PEG is the best for dissolving concentrates but am also interested in adding in a vg ejuice that is flavored. Thanks in advance.

Edit: When I say VG I'm thinking I'll use a 20%PG/80%VG mixture. Just wanting to add a flavored ejuice to it.

I'm unfamiliar with the specific atomizers you are talking about. Do you know the brand you're referring to? You will have a hard time getting the concentrate to mix with VG. Oil and VG is like oil and water... they don't mix. The only place I've seen have success with VG is SkunkPharm and they were using a high powered homogenizer. Here's the link:

http://skunkpharmresearch.com/game-changer-emulsifying-vegetable-glycerin-and-bho-for-e-juice/

My guess is, the resulting juice will still have separation even after homogenization. I would stick with something tried and true like the commercially available PEG mixes such as Vapeur Extract/Puff Majic. They usually contain PEG and a small amount of VG.

I'm trying an experiment.

I placed 3.5 grams of

and two vials of CC in a 10 ml brown bottle. I gave it a few days to see if it would dilute with periodic shaking, or stirring after heating to 140 F. About a gram seemed to have liquefied. I added two ml of EJMix to the bottle, and heated it up to 140 F a bit and stirred with a toothpick: I think that there is just about .5 g left to dissolve.

I'm going to leave it sit some more.

Hey! Ya, as @florduh said, that's too high VG%. For an experiment once, I tried mixing some zero nic 50/50 (PG/VG) juice with some pretty sappy wax (probably would have worked better with shatter, but not much better). With a little heat and a lot of vigorous stirring, I could get it to emulsify, but it would split over time. I could run hot water across the glass part of the tank for a few seconds then shake, shake, shake and it would emulsify again (for 10 minutes or so), enough to get a few tokes. It wasn't too big of a deal, but I wouldn't recommend it, and it would have been worse with even higher VG%.

I don't know for sure, but I'd guess the premade ejuice mixers that you can purchase for cannabis (ejmix, puff majic, vapeur extract, etc) seem to be somewhere around 15% VG, 15% PEG 400, 70% PG? THAT'S A TOTAL GUESS, but if I was going to try to DIY a mixer I'd start around there and begin tweaking the ratios. I know many people have done 100% PG (look back to the beginning of this thread), and plenty of people have tried 100% PEG 400. Both reported to work OK, but PEG adds a pretty bad plastic taste, PG alone won't fully dissolve, and mixing with no VG doesn't give as much clouds (if you like clouds). From what I've learned so far, it seems like there needs to be a little PEG 400 in there to actually dissolve the cannabis (it's possible it also counteracts the insolubility that VG brings to the party as well).

I'd love to hear from anyone who's tried experimenting with making ejuice mixers "from scratch" themselves. I haven't tried yet, but I have the feeling I will soon.

Interesting, keep us posted! What do you think your overall ratio is now of combined mixers to concentrate?

**Edited to fix my bad math... :/

I thought I saw somewhere that you can mix a 2:1 ratio of concentrates to vapeur extract. That would be 10 grams of concentrate mixed into 5 ml of the vapeur extract liquid. So, I assumed I could dissolve the 10 grams into 5-10ml of PEG400 and then add the other ejuice to flavor. It shouldn't separate since the shatter is already dissolved in the PEG400 correct? Also, I went ahead and just ordered a protank mini 3 to use with my eliquid.

Edit: @randomtoker I will be using PEG400. Sorry I wasn't clear.

 

[macbill]

It's just about 1:1. 3.5 gram concentrate to 3.2 ml mixers (1.2 ml CC + 2 ml EJMix)

I've only used vapeur extract flavorless with higher ratios (between 1:1 through 1:3, concentrate to juice). I haven't tried less than 1:1 myself though, so I can't verify. I know many people have reported using EJmix at lower than 1:1 so I'd suspect VE would perform similarly well. Your PEG400 + ejuice to flavor plan seems sound. I'd personally not use 100% PEG just because PG tastes so much better. I'd try some combo. Regardless, I think (don't know) that your mix should dissolve fine though with that much PEG, it's just the taste issue (but maybe your flavored juice addition will cover it). Let us know! Also, I'd suggest making small test batches to test and get it right (like working with 1/2 g concentrate at most), instead of blowing 10gs on something that you might not love. Enjoy, and share your results!

Yes, I plan on doing a small batch to figure out flavor and then if it tastes good I'll make a larger batch to test for separation. I got 3 extra shots of flavor in my mtbakervapor ejuice I ordered. It's a 20%PG/80%VG blend with no nicotine. I'll post results in a few weeks I'm sure.

Hey guy, I've been reading this thread for about a year and it's have to be the best on the web.

I've had nice success with Adding about .7CC (diff flavors) with 1ml of puff majic original with 1 gram of shatter. I find that CC has the best flavors around, no chemical taste at all maybe just a little with the puff majic in there. It's day and night though when I mix without CC. The chemical flavors just don't do it for me.

Lately I've been seeing some negative posts about CC and its concerning with no one knowing what's in it. So I am looking into vapor extract and holy terp.

My first question is, are they affiliated?? I got a direct link from vapor extract to holy terp.

My second question is, what is difference between them?

Is the vapor extract flavors good? I've tried a few of the puff majic ones and they suck. I've been sticking with the original.

Hey man, congrats on moving from lurker to poster (took me forever to make an account and post, lol).

There's someone on here representing VE/HT, maybe they'll speak up. I believe HT is a new line from the people who make VE. The VE site had HT listed as 'coming soon' for quite a while, then when it became available the new site dedicated to HT showed up and the one links to the other. So ya, same company different brands kind of thing?

I believe HT is basically 'VE Flavorless' as a base + various combinations of terpenes added to make their different 'flavors' (different from the normal VE flavors because all the HT ones use terpenes). Looking at bottles I have here... 'VE Flavorless' ingredients says: Proprietary blend of PEG400, PG, VG. The HT ingredients says: Proprietary blend with terpenes. So I think it's a fair assumption. One thing that is different on the bottles is the instructions: 'VE Flavorless' suggests 1:1 (mix:concentrate), HT suggests 2:1 (mix:concentrate).

I haven't tried any of the VE flavors. I have a bottle of VE Flavorless that I've almost finished. It worked fine for me, but I wanted to try HT for more flavor. I got a bottle of HT Philosopher (decent but a little too strong pine sap monotone flavor), and a bottle of HT Couch Lock (very nice 'dank' flavor). I like mixing them together. I would buy HT again, probably some of their other flavors that have more combinations of tastes in them (maybe Jack or Chill, or any of the others). So far so good with me. None of them will suddenly taste exactly like pot, but it pushes the flavor in the right direction IMO. I've been happy. I'm curious to hear other people's experiences.

**EDIT: I usually mix thin (more juice than concentrate), but next time I get some concentrate, I can try mixing lower ratio as a test if anyone is curious (I could try 0.6:1, HT:concentrate, like how people use CC and let you know).
