bho vs qwiso

Ive made bho a handful of times and have been pretty sketched out with the large amounts of butane just chillin boiling off. if i was to run several pounds into qwiso or bho what would be the easier and SAFER method of extracting this with the best yield. things im concerned about in order are first risk of explosion. I talked to the owner about these "bhogart" machines that are suppossedly enclosed systems that run huge volumes of butane thru a system processing 1-5 pounds. the thing suppossedly is contained there is no oxygen and no ability for explosion (as the guy explained to me) i dont really believe him. i have no info on ANYONE proving this is in fact true and sounds like an atom bomb waiting to happen to me. i know bho is definetly quicker to make then iso, but can iso be made inside? if it is made inside is there more risk for explosion? do explosions even typically happen with the iso method?? Time is not really an issue as i have my own house, but im also concerned with my neighbors seeing whats going on in my backyard. i have a very short fence and both multiple houses can see. im thinking if qwiso is as dangerous as making bho id rather just blast it. lemme know thanks

Iso is much less dangerous. Butane has a flammability rating of 4 iso 3. Iso has a lower explosive limit/ lower flammability limit twice as high as butane and it doesn't boil at room temp, releasing fewer dangerous gases at a time. Iso can be done indoors butane should not

If you want a more detailed answer.. read what is a purge in the concentrate section and I've pretty much laid everything out there.. butane is generally looked down upon. Go iso or hexane. For a pure product and better one

so if iso is flamable woudlnt it be feasable for an explosion if i did it in a large volume inside. also im taking into question length of time, butane probly like 2-3 hours. iso would be like what a couple days? btw whats hexane? i would be definetly down to lean toward the qwiso method because doing it inside is a HUGE plus to me for security reasons but if theres still a risk of explosion i dont really see the benefit of doing it inside and would most likely still do it outside...

I generally do half gallon runs at a time. Iso does not pool and flow on your floor like butane you also don't have to worry about static or a fan etc causing a spark. I have a smokeable product in 24hrs not using a vacuum to speed things along using iso.. hexane butane octane, rated by how many carbons, 6 and 8 with hexane and octane. The heavier the molecule the higher the boiling point. Hexane is similar to iso or ethanol in evap times.. but is pure unlike butane and the extra carbon makes it more non polar and a much better solvent.......you should a just read what I said lol


https://www.rollitup.org/concentrates-extracts/725958-what-isa-purge.html

Its long but I threw quite a bit of info in there. Possibly besides what I threw in frenchies page the biggest collection of knowledge I've given

wouldnt it just make sense to let the iso evap outside since there are def possibilities of iso explosions?

If you think there is a chance of that happening you probly shouldn't even be working with solvents period... learn about what your using. Learn the precautions you need to take. And what causes an explosion. After you've done that, if you still feel unsafe or afraid of working with these solvents indoors.. you shouldn't be working with them ....

Yea of course outside is always best but if you understand what your doing there won't even be a chance of explosions.. obviously I'm referring to class 3 etoh, iso , hexane ect
Besides cannabinoids in solution are 10 times more sensitive to light... their main enemy

dude ive blown at least 50 runs of bho and havent had a problem, but like i said i have no experience with iso and i just got a new house and want to take every precaution possible to ensure the least likely instance of something like that happening. surely you can understand that right. i know cannabinoids that are in soution are more sensitive to light and that it degrades it i was thinking of just making batches inside and letting them evap outside at night

THC weighs more than water..

ISO to strip + water to separate, perfect bubble hash every time. I evaporate my ISO with a 50% water mixture, it is NOT explosive.

when the ISO is evaporated in a 50% water/50% ISO mix, put the brown "Juice jar" in the fridge. Wait 24 hours for the THC to separate and fall to the bottom, siphon off the top 90% of the brown shit, don't disturb the hash on the bottom. Shake up the mixture, pour into a glass casserole dish and evaporate the water off..

You will get a pure and blond water hash when you are done, if done correctly. 100% pure bubble and great taste, no sizzle at all.

I use a health stone to smoke mine, very high THC. I would guess at around 60%-80% THC with this method. The trick is to keep on washing it and siphoning off the water. 1 gallon of 90% ISO will solvent about 28 grams of hash, if you have enough flower.



This explosive shit you guys keep talking about... scary.. Mine is blond, 100% bubble, tastes great, and makes the face grow cold after standing up quickly. No chance of BOOM!

Your process will lose a significant amount of terpenes but that it is interesting. I've never heard that method mentioned before, very cool.....doesn't happen to often

If I have the process imagined right in my head anyway lol....

I agree, that method is very interesting. I would love to see some end result pictures.

i dunno i think im leaning toward a qwiso extraction, i only asked about it being dangerous because ive read other reports of people exploding shit with iso extractions ill post the articles if i can find them.

I have never heard about that method either, not like I've been at this a long time though I like to make ISO just for the simplicity of it all. I feel with Butane you have to dress up like a freaking chemist with your gloves and anti static kit. With ISO I do it in my fleece Ninja Turtle jammies. I would never ever try and make BHO indoors.

I'm definitely going to be looking into that method further.

I've been making BHO regularly for over a decade now, never had any accidents or close calls. That is not to say it is without danger - just that it is relatively safe when done outdoors and away from spark or flame. The same is true of other solvents. Isopropanol, ethanol, acetone, hexane - they all evaporate into an ignitable gas. While they may be less explosive than butane, they still present risk, and if you cannot use butane due to harmful vapor or explosion risk, then you cannot use the other solvents as well, for the same reason. As long as youre outdoors, or have a ventilation enclosure and scrubber setup, there is little risk. The amount you want to extract presents some unique problems, however. Containers are harder to do, and I see many people using food grade buckets to hold their butane when processing large amounts. This is a big no-no: even if its food grade, thicker plastics have heavy lipid solvents trapped in them left over from manufacture, which the butane (or whatever solvent you are using) will extract out of the plastic and into your final product. As they are lipids, there is no way to separate them. Use industrial kitchen sized pyrex dishes, or just bite the bullet and get some large pyrex labware dishes from a discount lab supply for a couple hundred. They last forever and are worth the investment if youre pressing pounds. Another issue is evaporation rate: butane can evap quite quickly, which is a problem if youve a gallon of it in liquid form bc you just extracted a pound. The fumes are dangerous and pure butane has little smell, which can make for a bad situation! This can be completely prevented by putting your butane in the freezer. The temperature at which water turns to ice is happily also the temp at which butane turns from a gas into a liquid, meaning if your butane is freezer temp, it will remain a liquid at atmospheric pressure in an open container. Butane will remain liquid if previously freezered for over a half hour at room temp. You can also reduce the volume of stuff you need to process (assuming you are working with bud/trim and not leaf) by making dry sift or dry ice hash first - if you only extract the keif, you need much less volume and butane. FYI - it takes me one 12oz canister per oz bud/kief. What I would do, were I needing to make oil out of a couple pounds, is freeze my butane, get a nice pyrex evaporation tray from a lab supply and a cooler that is big enough to hold it, grab a pyrex flask big enough to accept all the herb, fill the cooler half with ice, the butane, the herb, and the dishes, load a 50' extension cord, power inverter, and 4-6 coffee mug warmers into the car, and drive out to the middle of nowhere. Plug in the extension cord and the mug warmers and take them 50 feet away from your car, and place them on the ground so you can set the evap dish on top. This needs to be done first bc plugging in the cords after youve begun may cause a spark. Test the electronics beforehand to make sure they are in good order, leave them plugged into your extension but leave the extension out of the power inverter. Once that is set up, place your bud in the flask, discharge enough butane to cover, then put it back in the cooler to chill and let soak. The butane evaporation at this point will have effectively stopped. I like to let mine sit for a half hour, but you dont really have to, it just squeezes the last few cannabinoids from inside the cells. Cover the flask with a brown paper coffee filter (or some 100 micron filter paper), and pour it into the evaporation tray which is sitting on the ice in your cooler. Then transfer the tray to on top of the mug warmers, retreat to the car, and plug in the cord to the power inverter and power everything up. The butane will be evaporated in a few minutes, the heat from the coffee warmer doesnt get hot enough to be dangerous, but really accelerates the process. By freezing the butane you prevent evaporation before you turn on the mug warmers, which really cuts down on the personal risk, esp as youre 50 feet away when evaporation starts. Whichever solvent you use (if you decide to), make sure you do a clean plate test - most of the butanes have heavy lipid contamination (esp the ones sold as X times refined or "pure") that is inseperable from your extract. But all of that is a moot point if you dont have a nice outdoor area to evap in, or cant afford a sufficient hood/filter setup. You can avoid the whole mess and get some excellent high purity vapable extracts by doing a heat only, solventless extraction, or a dry ice extraction. The first involves an oil bath and some steam distillation equipment (though it is not steam distillation, only similar), takes a long time, but yields a pure oil that is unsurpassed and can be done at home easily to large amounts of herb, the second involves a bubble bag of ~80 micron, and dry ice, and is the simplest process ever: you just throw your whole, unground bud into the bag (after placing the bag a fitting bucket), throw in a brick of dry ice, swirl the thing until the bud has crumbled and frozen, then shake the bag until the powder that avalanches out turns a bit yellow from its original white. Takes less than five minutes to process a pound, yields a fine white powdered kief that is purer than any water based bubble hash or RSO/ISO (or any oil that is made with a non lipid selective solvent), though still only ~80% cannabinoids with the remainder being plant material. You can vape that with any of the normal methods, except concentrate bowls or nails, bc the plant material burns in those devices. I recommend making dry ice hash and using that for butane extraction if youre processing large amounts, as it greatly reduces volume, but its important to note that this skews the cannabinoids ratio of your extract towards THC/CBN and away from the other secondary cannabinoids, which are quite beneficial medically, as the secondary cannabinoids are present in higher ratios in the plant material, which kief is quite low in. Anyway, sorry for the huge block of text - if for some reason you desire more, the link in my signature goes to an even larger selection of words, which explain the processes Ive described in more detail, and many other things besides!

I thought the ISO dissolved the THC into the liquid itself? Or am I missing something here? I was always under the impression, the stuff in caught in the coffee filter was junk so wouldn't that be this technically..? Maybe I am missing something really simple here, I wanted to give this technic a go that's why I ask.

It does....you also won't approach fully saturating your liquid for anything to really fall out.. but I can only speculate the faults in this method..it does sound interesting though, so don't think I'm "hating" on it, but I think you could improve the quality with a standard method

Typically I grow and harvest specific plants for hash making. Usually slightly premature.. and they go from chop to freezer so I never get an accurate weight.....but about 3ozs per plant, I use the whole plant, and pull 7-10 grams. Depends on frostiness of the plant and the yield, also where it puts its frost...anyways...yup that's it

Oh if your thinking I use a lot of iso, its cause I do a pour through method and it kinda wastes, I probly could do it with half that amount if I needed(maybe). But 10 bucks a gallon isn't that bad

Cool thread guys, I would LOVE to try some other methods if i was not afraid of doing it. I`m an easy pothead. I used to do the Butane a while back, I must have bought every butane can in every liquor store in town.. hahaha.. they even new me by name. I love the gooey and yellow taffy from the BHO extraction but it costs more, it is less productive (unless closed loop), it is much more dangerous, ect.. A local yahoo just blew the roof off of his house in town a couple months ago.. What an ass.. lolol...

Anyway, the ISO will dissolve the THC and other resins into a liquid. I use a standard for coffee making, metal-screen mesh as my filter. I use a 1.5gallon pickle jar, 4 quarts of ISO, and 4-6 ounces of chopped and dried trim or flower.

1. put the chopped and dried flowers in the pickle jar, (with a lid).
2. pour in 1 gallon of ISO, put lid on.
3. shake vigorously for 30-60 seconds.
4. strain the liquid into a large casserole dish
5. pour 0.5-1 gallon of water into the pickle jar with flowers
6. shake for 10-20 seconds
7. strain into casserole dish
8. put it on an electric oven - eye, I like to put a few layers of aluminum foil down to prevent hot-spotting.
9. put the oven eye on LOW (NO GAS, ONLY ELECTRIC) 50% alcohol / 50% water is slightly flammable at warm temps.
10. I like to put a desk-top fan blowing on the mixture, The mix should be dark green/black.
11. As the alcohol evaporates, most of the water will stay and it will separate the THC and resins.
12. The heavy THC will not evaporate if the alcohol evaporates from a water mix, water will contain the THC.
13. at this point the mix will turn a whitish / light brown color and smell like ganja, make sure NO alcohol smell.
14. Put the whitish-brown water/THC back into the pickle jar.
15. put it in a cold and dark place for 24 hours, the THC will fall to the bottom.
16. CAREFUL not to disturb the THC at the bottom, siphon off the top 90% of the brown juice and fill the pickle jar with more water.
17. repeat steps 15 and 16. The more you wash it, the blonder the finished product will get.
18. after washing and draining the white/brownish juice, pour it back into the casserole dish.
19. put a desk fan on it and evaporate the water..
20. Use a razor blade and scrape the THC and Hash from the casserole dish.


Careful, this is 100% bubble and the hash will burn like fuel. I place small bits of the hash on weed and/or vaporize it. The first time I did this and it worked, I said to myself, oh thank God.. Trim into gold.

I can take picture later, maybe one of you guys can be intrigued into this method and help make it better. It`s basically ISO stripped, water cleaned. As far as I am concerned, it is a method of water hash since water separates the hash from the other and worthless resins like chlorophyll and junk. It strips SOME of the flavor from the herbs too but it`s not much. I can taste which hash came from which plant, no problem there. I think the more you water wash it, the more it takes the taste out.

another thing, you have to wash it when it is still wet. If it dries, you cannot wash it again unless you dissolve it in ISO again. Water is a medium, not a solvent for hash. I can take some picts, I have some. washing 1x makes the brown and tar-like bubble hash, washing it more will make it turn into a blond and glass-like substance.

Hope this helps for some of you fun-timers.

Would love to see some pics of the process throughout but I understand if that's to much lol.. anyway thanks for sharing, I might try it next run in a couple days

So your basically just saying to wash your hash in water right? After already making iso oil

It should also be noted that while iso is fully miscible in water and the addition of does reduce its flammability, this does not change the properties of iso's vapors being released into the air.. and the 50:50 mix is still flammable. I'm nit sure at what % its not though.. would have to check up on that

50% alcohol + 50% water = 100 proof. Generally, 100proof is not flammable unless it is heated and the vapors can light. It takes me about 6 hours to slowly boil off the alcohol smell. I think overheating the hash will fuck it up too, so low heat.

Made a few pictures, you can see the difference in the hash from different water washings.


Edit: Here is some hash I have now, I bought a qp of Mexican brick for $100 and turned it into about 1ounce of this. The tar`ish ball was a single wash, the powder is washed 3x.

yup, make sure you wash it while it is still suspended in alcohol. Oh... one more thing.. ISO can only hold so much resin per 'mol' weight. 1 gallon of ISO will not pull all of the resin out of about 8 ounces of high-grade.. You will be limited to the hash you produce by the amount of weed used and ISO used.

Overall Mol Weight is dependent on ISO used as solvent or else the solvent will reach it's critical limit, this is how you can use the "water wash" method for THC. Too much hash = a lower solvent level in ISO. I am a college level mathematical chemist with a strong background in THC. hahaha.. <3
