My first attempt at QWISO

Just as the thread title says I am trying my hand as some QWISO... attached the process I am using. Thanks to @Thundercat for the tech I copied from his thread Thundercats Groooooooow! (such a sweet thread name btw lol). Everything is in the 1 hour chill stage atm. I did decide to use my 220 work bag for the initial filter because I know from using the bags to make bubble that it keeps all the actual plant material out. Also I have found some sweet amounts of really nice looking wax in the 120 and even once in the 160 bag depending on strain so I don't want to lose those nice large indica heads. Also the third wash since only going to be for edibles or salves I shook the shit out of it for about 3 minutes lol so we shall see how that turns out!

Updates to come!

1. The Prep: we will need the following:

a. 91% ISO Alcohol

b. “work bag” (jam strainer or possibly bubble bag work bag)

c. Approx. 6 collection containers (depending on how many washes)

d. Paper coffee filters

e. Metal coffee filter

f. 3 pyrex dishes (depending on how many washes)

g. Parchment paper

h. Product!


2. The Freeze: add all of the following to the freezer overnight.

a. Product (lightly chopped and large steams removed)

b. Alcohol


3. The Wash

a. Have 3 collection containers ready, as well as the work bag and metal and paper coffee filters. Have 3 coffee filters inserted inside the metal coffee filter. Have this over a collection container.

b. Add ice cold alcohol to the product to cover just barely over the product, then add a small amount more.

c. Mix the product very lightly for approximately 30 seconds for the first wash.

i. SECOND WASH: mix lightly for 1 min.

ii. THIRD WASH: cover jar and shake vigorously for approx. 3 min **EXPERIMENTAL**


4. 1st Filter: Have a collection container with the metal coffee filter ready and then the work bag over that.

a. Pour the wash through the work bag and into the coffee filter covering the collection container.

b. Let all of the solution drain through the work bag, then squeeze as much of the solution out of the product as possible into the container.

c. Now add the filtered solution to the freezer and return to step 3.c.1 and .11.

d. Add all 3 washes to the freezer.


5. ALLOW TO CHILL FOR APPROX. 1 HOUR


6. 2nd Filtration: After all, three washes have been allowed to chill for at least 1 hour. Grab the paper and metal coffee filters, and one extra collection container.

a. Add 3 coffee filters to the metal coffee filter. Add this to the top of another collection container. Pour the wash through the filter combo. DO NOT FORCE OR SPEED UP THE PROCESS. Re add the filter and container to the freezer and allow to filter completely. This should take approx. 30 min.

b. Squeeze out the paper filters into the “Wash off” container.

c. Re-add the twice filtered solution to the freezer.

d. Repeat all of step 5 for the 2nd and 3rd wash solutions and leave all 3 solutions to freeze for approx. 3 hours.


7. 3rd Filtration: After all, three washes have been allowed to chill for at least 3 hours. Grab the paper and metal coffee filters, and one extra collection container and the 3 pyrex dishes.

a. Repeat steps 6.a through 6.b.

b. Add all 3 of the 3 times filtered washes to their own pyrex dish.


8. Evaporation: Will need a fan a small heating element also preferable to have an exit fan to outside.

a. Add the pyrex dishes to the heating element and the fan blowing over them to speed the evaporation process.

b. Wait 24 hours.

c. Check to see that ALL moisture has been removed from the final oil. If it seems to have more moisture let dry longer.

d. Use a razor to scrape hash/oil onto parchment paper and flatten.

e. Fold and re incorporate as desired. Weigh if desired… and dab away!

Finished up everything this morning.. the 3 hour freeze turned into over night since I started at about 10 pm.. but all is in my atm vacant bud drying space dehumidifier and fan going on low and have my large cfm exit fan sucking out any unwanted fumes directly to outside. Hopefully I see what kind of yield I have in 24 hours or so! Wish me luck!... also does anyone know if there is something better I can use that coffee filters? Such as a properly micron sized re-useable filter? PS sorry for some of shtty pics lol

Nice dude, those washes look spot on! I've looked into better filters, but always come back to coffee filters because of price and they do a good job.

Thanks man!! and yeah you can't argue with functional AND economical.. I will hopefully post pics tomorrow of some nice finished product!

Id like to add something...

Make sure they are unbleached coffee filters (the brown ones).

Dont use parchment paper. Iso strips some of the plastic and it ends up in final product (dont use plastic). Use dab mats or pdfe sheets.
Also dont squeeze. You want your product to not end up green. Squizing makes chlorophyll go into the final product.
Also put in an oven for 230f and watch all residual iso bubble away. When the bubbles start to lessen and when there is barely any bubbling you should have taken out some of the residual iso. Dont dab that shit thats only been evaporated!!

Hello man! thanks for the insights!

I did use the unbleached coffee filters and will make sure to note that.

As far as the parchment paper.. if I do the ghetto purge that you were talking about would that still be an issue? I see people putting bho and all kinds of waxes on parchment... is it specifically the ISO or any remnants that are striping things of the parchment paper?

In reference to the "purge" will 230f effect the product at all? and can I do this right in the Pyrex dishes? any idea on approx. time or should i just watch for bubbles to dissipate? I was worried about this and not have a vac set up etc... I just need to throw down the cash and get some plates and a press....

On the last point... but I want to squeeze to get all I can out of it!... but yes I know... lol I think I will start just saving the filters from the first two washes non squeezed and add them to the third since a little chlorophyll in salve or edibles is no biggie.

Sorry about all the follow up questions but I appreciate the insight man!

I picked up bits and pieces of doing iso here and there. I cant remember where I read that iso strips plastic. Something about polarity or something.
Heres a good read https://skunkpharmresearch.com/qwiso/

Doesnt take much time. Maybe 1-15 min if I remeber correctly. The article above talks about that.

Another tip I picked up somewhere else, when you have your filter setup add a little bit of just iso to wet the whole filter part. Then add your product. Should prevent clogging too soon to some degree.

Useig parchment to store finished concentrates will not cause any issues with contamination please don't spread advice when you don't know what your talking about.

Heating the ISO solution in the oven is also terrible advice. It could easily cause a fire and it will destroy you mono terpenes.

You want to evaporate your solution with little or no heat at all! ISO is not like BHO you do not need heat or a vacuum to remove the ISO. You want moving air on a thin film evaporation. ISO completely and cleanly evaporates at room temperature.

Sorry I forgot to mention to let the iso evap to as much as you can and THEN throw whats left in the oven. I thought that was obvious but I guess you didnt pick that up. Hey man @Fadedawg used to work with skunkfarm. Whoever wrote that article on skunkfarm must be wrong then? I followed most of those rules so I dont know all the technical stuff.

When they are putting it in the oven at the end it isn't about evaping it, it's to decarboxylate it. If you want to eat the concentrate but aren't going to cook it then your can decarb it to convert the thca into thc so it will get you high. I you are dabbing it then there is no need to decarb it or put it in the oven.

hmm this link states for vaporizing to purge off the iso using a hot water bath at about 140 degrees.... the higher temp stuff mentioned seems to be talking about topicals... which is also very useful to me ... however an oil bath sounds.... daunting and like a HUGE mess

yeah I read that whole article ... here is what they say about evap off alcohol for vaporization....

"When the alcohol is visually gone, place the dish on a 140F heat mat, or float it in a hot water dish, until the smell and taste of the Isopropyl is gone, usually around 30 minutes to an hour."

You really don't need to do that it just makes it evap faster. Maybe if you had a really large quantity run with huge amounts of oil. But I do a quart at a time and all the alcohol is evaporated leaving only dry crystal oil. No residue, no smell, not flavor.

I looked back at it and I swear its like the nelson mandela effect is going on. Or maybe I read that shit wrong or read it somewhere else. I did the water bath at 140 too and that shit didnt even work for me. It would have taken way more than 30minutes. I remember it saying to put it in the oven at 230 and wait until bubbling ceases mostly. I dont even smoke and this shit is tripping me out LOL.

Lol it's funny how that works when you want I find something. I tell almost everyone try some different things. That's what I did. Over a few years I tried lots of variables and read lots of info. That's how I decided on how I usually make oil. There are lots of ways to do it. Some get higher yield some get more flavor and some have a faster process. I just settled into a process I like that seems to provide the best flavor and decent yield for the amount of time and work it takes .

I might try your method one day. Heres a thread I seen you post on. I tried doing qwizos way but I could never get it to work. https://www.rollitup.org/t/qwizos-qwiso.831286/
Op that thread might help some too,

interesting thread... some older tech it seems but sounds very similar... there are some weird posts at the end.. like someone covering product in iso and then microwaving it and ... yeah i think i stopped there lol

I sit all my 3rd + washes that are green in the sun,or under a strong grow light for a few minutes. Bam,chlorophyll gone!!! Back to amber,golden etc.
