Hey all! DISCLAIMER: I searched around in the 'cooking' sub-forum, and here in the 'concentrates' sub-forum and haven't found a thread dedicated to the subject in the title here (high potency tinctures made from concentrates). It comes up in passing in some related threads but I haven't found this specifically. Lemme know if a more relevant thread already exists and I'll join there instead. SPIRIT OF THIS THREAD: The spirit of this thread is "quick", "accessible", "potent". There are manu slow, inaccessible, heavily diluted recipes out there using whole herb. Let's talk fast, easy, powerful starting with concentrates. I forgot the word "Fast" in the title, this is really to share things a total noob could do fast with little resources. Concentrates are getting more affordable and accessible, they could provide a great shortcut for people who don't grow or extract. Here's what I've found from searching around yesterday: QUICK DECARB ETHANOL TEK: I found this step by step pictoral tek on imgr. It's simple and I confirmed it works. http://m.imgur.com/a/7CrhX Summary: - Heat concentrate at 270f for 12 minutes to decarb - Mix in desired ratio of 190 proof ethanol Notes: - The important thing from the imgr pics is that concentrate can decarb fine in 12 minutes at 270f in an oven. I tried this, it works. This is cool news to me. - FYI, THC solubility in ethanol is 1:1 so "technically" you could go pretty low if you had very pure concentrate (winterized/dewaxed) Advantages & Disadvantages: + Alcohol under the tongue absorbs into bloodstream quickly + Alcohol is less viscous than coconut oil or honey, so it's usable in portable dropper bottles + fast, easy, and accessible, procedure and tools, single step decarb, no oil bath needed - Alcohol burns under the tongue - Alcohol makes your breath stink, could lead to undue attention - Problematic if you don't want to consume any alcohol - May not need to go up to that temp (comments?) QUICK BOIL GLYCERIN TEK: This tek is from an old thread on THC Farmer boards by user pirobot668. His info was still experimental and I've never heard anyone else try this. The info is spread across these 3 posts: Post 1, Post 2, Post 3 Summary: - Heat glycerin to THC vape point - Drop in bits of concentrate - Concentrate vaporizes but the THC in the vapor is immediately captured by the glycerin - Remove unmixed oils and re-drop into hot glycerin (repeat, like doing multiple washes in an extraction) Notes (from those thread posts): - Solubility of THC in glycerin is 1:3 (pure thc to glycerin) so "technically" you could get pretty potent with very clean concentrate if successful - Glycerin boils at about 550 F, THC around 320 F, CBD about 360 F so you could pick your temp if you want cerebral or medicinal effects. It's possible this can still be successful at lower temps than 320, worth experimenting - Winterizing initial concentrate, and each separated oil capture before re-dropping maximizes efficiency (ie: the cleaner the concentrate you're dropping in the hot glycerin, the more THC you'll catch each time) Advantages & Disadvantages: + Glycerin is less viscous than coconut oil or honey, much easier to use in dropper bottles - might be tricky to not waste THC doing this, need to experiment with temp ranges - could easily end up with derpy, sleepy, weak, overdecarbed tincture, gotta try -------------------------------------- My attempt at Quick Decarb Ethanol Tek (QDET?): Order of pics: top to bottom on left, top to bottom on right, final result in center Notes: - only have 150 proof everclear but tried anyway - used 1 gram of cheap dispensary wax - decarbed in pyrex jar in oven at ~270 for 12 minutes (it bubbled, then settled and clarified) - slowly mixed 3ml ethanol, then added 6 more for total ratio of 1:9 (wax to everclear) - mixed for a few minutes with fast coffee mixer in bottle (probably unnecessary) - let sit for a while (not necessary, just curious how much it would separate) A glob of oily stuff formed at the bottom that is roughly 1/3 the size of the original gram of wax. I'm not sure if that would have fully dissolved if I used 190 proof. Has anyone tried something similar? Thoughts? I assume if the wax was ~70% thc then this is the 30% remaining plant matter. Remixes easy with mild shake, but separates again quick. 6-12 drops under tongue and a mellow cerebral high arrives 5-10 minutes later lasting a couple hours. 24 drops under tongue (burns!) yielded excellent (++) 4 hour high. Rough potency math: If my wax was ~70% THC, then there was ~700mg THC in 1g. Final mix is ~10ml total (1g+9ml) so it is roughly 700mg THC in 10ml so each 1ml (or 1 dropper of my bottle) contains 70mg THC now. Make sense? So a quarter dropper is about 17mg which is a mellow/mild candy edible dose for me. Next time I'll try highly concentrated (1:2 - 1:4) so it's very minimal drops required. I intentionally didn't mix this for maximum potency/concentration because I wanted to test the lower threshold first. No concentrate left. Next time I get some, I'll try the Quick Boil Glycerin Tek (QBGT?) as well and post results.
