Considering QWET - School me!

[owin]

So I just finished my first go at QWET.

I followed skunkpharm and @2clicker method pretty close. I did 2 washes but into the same dish instead of separately. I know what I did wrong and know where to improve next time. I definitely need a better filter process. I think I might need to "wash" it a little more vigorously next time too as the buds still looked like they had a lot of trichomes left on them. I currently have the buds in the freezer. I'll probably do another wash again tonight.

I ended up doing a fan on my pyrex dishes that were on the stove. I aimed the fan to blow over the stove and out the window. It actually went a lot faster than I expected.

Pretty fun and relatively easy process. I just took a dab on my omicron with kiss cart and I am feeling good. It tasted exactly like the bud smelled.

If you do two washes you should try to keep them separate, the first will be far headier

 

[darkrom]

Most definitely would be. To be honest I'd do 3-4 washes, I just need to get more pyrex and slick mats lol.

Haha this was my exact problem. I didn't have enough stuff. I know for next time. I know everywhere says keep separate but I was impatient and just testing the process in general. I won't make the same mistake next time.

yup there is some left, but dont shake it too hard/much. keep doing what you are doing, but do more washes. only problem is that after the first 2 washes most of the trich heads are gone, but there is still medicine on it if you can easily see trichs on the flowers. i personally keep washing until its hard to see any trichs anymore. that is usually 3 washes, but sometimes 4. also, the 3rd and 4th washes get extended washing times as i am not worried about the stuff you dont want in your dabbing oil. so it would be ok i suppose to shake the shit out of it for the later washes. just dont do that for the first 2. washes 3 and 4 give you some potent medicine, but its got lots of stuff that you would normally winterize out for dabbing. i use the oil from washes 3 and 4 for use vaping with flowers. no wick to gunk up and still getting well medicated. and best of all is knowing that you squeezed every last bit of goodies out.

as for filtering. check into the 316wholesale SS mesh filters. far better than using paper filters. enjoy!

So I'm gonna do my maiden QWET run tomorrow. What would we recommend for the process? Is it different scraping QWET off with a razor blade to QWISO oil? How am I best to do this. Gonna use about an oz of trim with 95.7% spyritus.

I was thinking wash without grinding (lots of fallen off trichs in the trim, a few small buds too), 3 mins per wash, 3 or 4 washes. Unbleached coffee filters for filtering and filter solution several times before evaporating. Evap down in pyrex double boiler and then scrape off dish. Am I on the right track here?

 

[2clicker]

@herbivore21, follow the skunkpharm QWET directions and you are golden.

oh and i would not grind trim at all for a QWET run.

 

[Roth]

Going to try a QWET run in the not too distant future myself. I didn't realize QWET could produce this kind of quality, and I can't run BHO due to being in an apartment complex. Really appreciate all the help/info.

Think I have everything planned out in my head, just a few questions about filtration. I plan on buying an AeroPress and cutting some SS mesh screens to fit inside.

First question, can I make a stack of different SS micron sizes and filter everything in one pass? Or do I need to do separate filtrations for each progressively smaller micron size?

If I do have to do separate filtrations for each micron size, do all filtrations need to take place in the freezer, or just the initial soak/wash?

I'm understanding correctly that people have not found a need to winterize if filtering the concentrate through 25u or smaller screens?

Thanks again for all the help, the thought of producing my own concentrates is very appealing!

 

[2clicker]

@Roth, there is no need to stack the filters. if you are using an aeropress then just use the smallest micron filter you have. if you are letting gravity do the work then you would want to use them all. otherwise the smallest micron mesh would take FOREVER to filter through. the aeropress should make this a non issue, but i have never used one.

only the washes need to be done in the freezer. and remember to let your ethanol and starting material freeze before any washing takes place. i put mine in the freezer the day before the wash, but a few hours should be long enough.

i have not found the need to winterize when using 25u or below to filter. my oil comes out very clean. as long as the wash is timed correctly and filtered down enough there is no need IMO.

 

[Roth]

Very nice, this might be even easier then I anticipated.

Think I might order some 10u and 25u just to experiment with and see which I like better.

 

[herbivore21]

Ok, so I decided the trim was QWISO quality but not something to waste $30 worth of ethanol on. This was serious QWISO though, sorta like a thick mid brown (half-way between amber and black) wax.

Big payday on the way, might dedicate a half oz of fresh sublime nugs to a QWET run

I have never tried shatter/honey oil/wax before. All I have tried in the past is bubble/kief/QWISO!

how much trim are you working with? would it even take a whole $30 bottle?

and if you have used QWISO then you have used shatter/honey oil/wax. QWISO will make those forms of oil. QWISO is not the same or similar to bubble or keif. QWISO (quick wash iso) is just like QWET (quick wash ethanol) except it is extracted using a dif solvent. both will make oils of dif forms (shatter, wax, etc). no solvents are used to extract bubble and keif.

That feeling on a thursday morning at work when you realize your QWET has been sitting on the griddle for 24+ hours and you totally forgot about it....

OH NOOOOOOOOO!

 

[darkrom]

It looks just fine. got it off the heat. Might have less flavor, but oh well. I've got 2 more runs to evap eventually from the same bud.

It still smells like blue dream, so chances are the heat was low enough that it has most of its flavor. Shatter pics coming soon once I have time to fold it all up.

@darkrom, pics?? I remember seeing your lab test! Love seeing pics of your stuff, best I can get here is the castrated version of Everclear...

 

[Roth]

Did my first QWET run last night. 10.5g of some pretty nice Green Crack. I loosely broke the bud up into pieces roughly the diameter of a dime to 2/3 of a dime, without grinding.

3 minute wash, with swirls every minute on the minute. Quickly strained using a stainless steel strainer. The ethanol quickly went into my AeroPress with a 10 micron filter in the bottom. The liquid passed through the filter with relative ease, much easier then I expected.

The 10u filters are incredibly fine. They feel like nearly like smooth fabric in your hands. Can't really even see through them! Would love to check them out under a microscope. I looked with my hand-lens from geology, but it wasn't powerful enough to see much of anything.

I then quickly encountered a step I hadn't really thought about. When preparing to do a second wash, should I dry the bud fairly thoroughly, then refreeze and treat it like the first wash(waiting several hours/overnight)? Or simply throw it in the freezer right after the first wash and begin the second wash immediately.

I ended up settling sort of in between, mainly due to time constraints I did not anticipate. I let the bud sit in the strainer for ~30 minutes near a fan to do a quick dry. I then placed the bud back in the jar and placed it in the freezer, where it still currently sits.

I had an unexpected work event, and won't be back home until tomorrow to resume the second wash. Hopefully this doesn't cause too much of an issue.



Back to the first run. I put it in an Oil Slick Pad lined casserole dish. Covered with some SS mesh, with a fan pointed directly at it. Unfortunately, by the time I had to leave, it was not evaporated yet. I'll be home tomorrow morning, so it should be done by then and I don't anticipate too negative of an effect from that amount of time.

Still too early to tell how much yield from the first run, or even the quality. When I put the bud back in the freezer for the second wash, I could clearly see a decent amount of trich goodness left. It took some self restraint to trust the masters and not grind the bud, and not soak for longer!

Will update once I have the end result to show!

sounds good! dont do longer washes until the 3rd-4th washes. he first two should be at 3 mins.

pretty cool to hear the aeropress can be fit with the 10 micron mesh. i may have to invest in one. i just wish i could find a glass or SS version.

 

[Roth]

I'll definitely stick to 3 minutes for the first two washes.

What do you typically do between washes? Just throw the bud straight back into the freezer for a few hours, or do the next wash immediately?

Regarding the AeroPress, it would actually be very easy to adapt to any filter. The way it works, the main cylinder has a lip that "locks" the filter in place. The filter is actually slightly larger then this lip. That way, you don't have to worry about getting a perfect circle to get a good seal.

Not sure if that makes sense, but the the filter sits in the black piece at the base of the unit. This part snaps onto the main cylinder. The main edge of the cylinder is ~1/8" smaller then the size of the filters, thereby allowing you lock the filter in place.

My 10u screens cut quite easily with ordinary scissors, I just used an included AeroPress filter for my template.

I also wouldn't be too concerned with the contact of the plastic in the AeroPress. My liquid was in it for maybe 30 seconds, tops. I thought I didn't get a good seal, due to how quickly the ethanol ran though. However, when I removed the filter, I could clearly see where the filter was locked in place by the main cylinder by the debris left behind.

for the second wash i used to dry it and then refreeze and wash it. now i just wash it again right after separating the flowers from the first wash. i pour more EC in the jar and back into the freezer it goes for another 3 min wash. i really only worry about it being totally frozen for the first wash.

thanks for the details about the aeropress. your description makes total sense.

 

[darkrom]

Honestly I do only about a minute tops on my first wash, I just can't freeze it. Bottles of ethanol and jars of weed don't go well in my freezer here.

I feel like I have no problem doing even shorter washes, 30 seconds even...as long as you do another wash after.

From the first wash I got .8g of some good looking blue dream shatter. Not much of a smell that I can detect, so I probably lost the terps in the 24 hr heat purge, but mistakes happen.

So .8 from 1/4 isn't exactly good, but I've never done a 2nd wash, and right now I have a 2nd and 3rd wash sitting out just reducing in open air right now.

When I have time to monitor them I'll heat purge them down too. I usually get 1g QWET hash per 7g of bud. Hopefully the 2nd and 3rd wash make that return a lot nicer, without ending up with garbage.


EDIT: Pics of the first run in the share that dab stash thread.

even if your later washes come out less than desirable, just use them in herb/errl/herb sandwiches in your favorite flower vape.

interesting about your wash times. this is with Everclear right? i find when i stick to a 3min wash that i get about .7-1g from a 1/4 (first wash). so to see you get that same return from a 30sec-1min wash interests me.

 

[darkrom]

Good to know we are on the same page with the first wash. I have been screwing myself by not doing 2nd or 3rd washes, I'm curious to see how much I end up with total.

Yes I use everclear. I really have no desire to go back to making BHO at this point. I'll still vape it if it was made correctly, but I'd prefer my QWET.

Might finally have a chance to get CO2 oil soon.

 

[darkrom]

I can't edit, so hopefully the double post is ok.

I weighed the 2nd run. .47 so with 2 runs I got 1.27g which is 18% so far. 3rd run is evaping.
