First time QWET can you check the process so I don’t scew up

[bongboy8200]

What’s up guys. So I got into making bubble hash and pressing into rosin. I guess there’s advantages and disadvantages to both but the molecular biologist in me makes me like to play with things. (Good ol days of using chloroform and different strength etoh to extract RNA)

So I don’t right a book qwet
-22g random bud mason jar. some premature. Nothing crazy not a great grow. Broken up and frozen in a mason jar.
-2 frozen 200 proof ethanol mason jar 1/2 full (it doesn’t say safe to ingest and for food but I think they can’t say it… Nonissues ordering a quart at a time just $17 in shipping. So like $50 a quart (if I get into it I’ll recycle).
-frozen strainer

Process - the timing is what’s getting me!
-Pour etoh into mason jar with bud.
-mix don’t shake for 1 minute
-freezer -1 minute
-repeat for 5 minutes
-Use metal strainer into empty mason jar
-freezer 12-24hours
-strain through brown(unbleached coffee filter into Pyrex
-crock pot for a double boiler with no flames 175°f (the water or should the be hotter since heat will be lost to the Pyrex dish) until etoh is evaporated
-scrape off waxy goo
-waxy go goes into vacuum purge chamber. Chamber into crock pot or electric heater 175° @ -29psi
-watch for consistency. The longer in the vacuum will make shatter

Really looking to make some sort of a sugar I can add to drinks when I’m out. I’m sober from booze and weed is a huge help. I still get the itch at the bar and suck down 100 club sodas. I know I can decarb. Qwet and skip evap. Use drops but don’t need any booze in me.

Any help or pointers? Do I need to purge to evaporate or can I do it all in the vacuum?
I see different times. For the wash. Some say 30 secs in 99.9% etoh and a swirl is enough to strip the Thca but not the chlorophyll but also leaving thca on the table.
I like it to dab. Melt and coat nugs.

And mostly make my own vapes which I see more on the right and wrong way and solvents. I like solventless bc it’s clean but the scientist in me understands why this works. Etoh isnt harmful compared to iso or butane. And I’m still going to vac purge so nothing to kill me on there.

Any help thanks you thank you

I’m a big fan of qwiso and put a lot of time into it some years ago. There is actually a link at the bottom of this post in my signature line to the process I used. It was an amalgamation of things I read from others as well as experiments I did myself, nothing ground breaking just a solid, simple DIY.

The recipe you listed will produce an extract, but with soaking it for 5 minutes and using heat to evaporate it you will get a darker product with less flavor.

the shorter 30 second washes you see people do greatly decrease the amount of chlorophyll contamination as well as the amount of fats and lipids that have time to dissolve during the extraction.

Keeping everything as cold as possible also really helps.

I’m also a huge fan of no heat evaporation. I used a large flat Pyrex that I laid a filter over and then used blowing dry air from my dehue exhaust to evap the alcohol. I could fully evap 1 quart of alcohol in about 24 hours.

So this is what I do. This produces a clean, smooth, and flavorful concentrate.

Contrary to the majority, I soak for 24hrs minimum. If everything is completely frozen (solvent, flower, vessel) prior to adding solvent to flower, there is not much to worry about as far as chlorophyll goes. You will always get some. Even using isopropyl.

Have a Buchner funnel prepared with DE and frozen as well. I immediately filter the frozen solution thru DE to remove any lipids, waxes, or fats. This also removes all plant particulate.
I then warm the solution to room temp and do carbon remediation.

The magic happens with the addition of carbon directly to the solution and then filtered thru DE. The carbon will remove any chlorophyll picked up in the extraction. Carbon also removes other nasties. Resulting in a smooth and tastey dab.

As mentioned by @Thundercat , heat is your enemy! If all possible, evaporate under vacuum. You will only need 38C-40C. Well below the threshold.

So a quick 30 second wash. Throw the metal strainer and back in the freezer. 12 hrs. Strain through the coffee filter. And go straight into the vacuum. I use a heat mat for seedlings. Goes up to 110°F. Put the stainless chamber on that. Speed the process up a little.
also without heat I would need to decarb if it’s not something I’m smoking? Ie canna sugar to add to drinks or for a vape juice? Or is that 110 with the vacuum enough to decarb? I read decarb after gives better flavor. Thank you for responding

I believe you only decarb for edibles, dabs you don’t need to

1) I do a 2nd quick wash. The soak time is the time it takes for the last Buchner funnel (from first soak) full of solution finishes. Then I then filter that thru at the end.
- If under vacuum in chamber, you should need no more than 40C inside.

2) As @sdd420 said, I only decarb if edibles. No need if dabbing.

3) And to the contrary. Decarbed weed tastes like dog shit. You will lose the terpenes in the decarb process. That is why you want to do everything at lowest temps possible.
