How many times can I run a bho run?

How many times can I reblast a single run? I've blasted it about 4/5 times now haha and still have gotten some return! I looked at it again the other day and it still smells like thc. If I break it up more can I run another can through?

lol I find the old tube method can take half a dozen runs to fully extract. Have you heard of the jar or thermos method? It extracts damn near 100% in one run. The difference is you chill the butane in the freezer, so it remains a liquid rather than evaporating off, then let the liquid butane soak your ground herb in a jar outside for at least half an hour (the cold prevents the butane from evaping, you can use a thermos or put the jar in an ice chest outdoors if you want to soak longer, then filter and evap. The long soak is really effective; I get 2x as much oil from a run vs the older tube method and i only use one can of colibri per oz, 1/3 as much as a single tube run. For full details and a clearer write up of the process, check out my Vapor Volumes, under the Oil section

iv noticed and wont run the tube method unless i have to. soaking in the freezer then straining in the freezer is safer then open blasting over here as well so bonus. just remove the bulb from the freezer

vlad, i cant find your thread on making thc cyclodextrins....

I dont think that leaving the open butane in the freezer is safe. The cold should keep it in a liquid state but butane is an aromatic hydrocarbon, so some will sublimate. I have no idea how much but it would take very little to fill a freezer space enough to make a spark explosive. Sort of like gasoline, a mix of aromatic hydrocarbons that are liquid at room temp, but still sublimates enough into gas that it has a detectable smell an can create dangerous, ignitable vapors, especially when its hot out temp is right around the phase change temp for liquid to gas, as butane is in a standard home freezer. You can create a temp much lower than your freezer is capable of reaching simply by taking a cooler and filling it with ice, enough water to wet it down, and a couple pounds of ice-cream/rock salt. The solution will reach -20F and stay there for hours. You can place your jar of butane and herb into that and it will stay unevaporated for a ridiculous amount of time, and I assume the much lower temp of this than a freezer (-20F vs 20-32F) helps eliminate any sublimation. https://www.rollitup.org/medicating/638018-anyone-know-how-make-cannabis-2.html#post8936954 is the only place I can find mentioning it. Its a simple process, take cannabinoids, guesstimate how much cyclo needed, mix, allow to sit for a long time, hope. The problem is BHO and similar extracts are extremely variable in terms of compound types and ratios, all with different sizes and cyclodextrin binding affinities. Luckily its a harmless if expensive sugar you are adding so you can overshoot wildly and still have a perfectly good water-dissolveable if somewhat sweet additive for medication.

Thc cyclodextrins..haven't heard that in a minute...figured I would toss this out
Aqueous solubility of THC increased to 1.65, 2.4, and 0.64 mg/mL in the presence of 25% w/vHPβCD, RMβCD, and SβCD, respectively.
Significant degradation of -THC was not observed within the study period at the pH values studied, don't drop below ph1.2, ph is extremely important in solubility. Only stable up to a month (chilled and in the dark) and must be kept at ph of 2

i hate the hoping part lol

I generally want a 500 mg drink maybe 300 for light weights..say you effectively get 1mg per ml and keep that soda at ph of 2 it wouldn't be all that potent...this isn't an effective method, which is why it hasn't been capitalized ....but it will work....33 tbsp per 16oz soda....yum

i would like a thc powder i can add to any drink to make it a cannadrink. how is the shelflife of the powered thc itself is the question.

Did you see that link vacpurge reworked for me to actually work, in the iso thread, it has some graphs I think for quick info but it has degration rates in etoh solution and as hash oil..its fairly stable in solution if kept out of the light. In solution it doesn't react with oxygen opposed to solid form.. lecethin would be your best bet in my opinion to get a thc infused polar drink using an emulsifier , unlike bhang or something. Thc is hydrophobic so this is kinda a tricky thing your asking of it..its never going to be super effective

Ultimately when I want a soda, I just use limonene tincture diluted into an equal volume ethanol with a touch of glycerin to make it water soluble. Cyclodextrins are just too much work just to make an oral prep, though the limonene overpowers other flavors so if you arent into citrus flavor right then, it can be off putting. The soda industry uses oil flavorings in soda and makes them suspend in water with brominated vegetable oil or ester of wood rosin, though the former has some controversy regarding safety. I dont think this will work for hash oil extracts, as they are very dense, and this method only works with oils that are lighter than water - if you calculate out the specific gravity of your extract, and it is less dense than water, you could go this route. I've never tried; the health concerns are enough to scare me away from traditional sodas as is, and I've no desire to try that for medication. TLDR; easiest, most convenient way I know for drinks is to make an ethanol tincture and add some glycerin. It will be more dilute than most oral tinctures made for direct consumption, but you can make it so you only need add a 1/4 of a fluid oz to your drink, something easily carried about in little 2 dram vials to be discretely added to your drink at restaurants, family reunions etc.

Yea i havent had a soda in years.....Roughly 2 tbsp (24 ml or so )of etoh will dissolve 500 mg of thc, you can pretty much add that to any drink and it won't add much alcohol but you get a good amount of thc

yea i would add it to juice and water though, im passed the soda craving. lemon limonene? ice teaand water with lemon sound good !specially medicated water

someone got a lab coat and a PHD i can borrow?.....

id like to hang out in this thread but i feel terribly small..

Thought I would share this link..I think it pertains, https://www.google.com/patents/EP1539069A1?cl=en
Read the whole thing..yes all of it, I know blocks of text are daunting lol... You will learn a bunch or atleast learn a bunch of things to google

blocks IF text can be daunting, but blocks OF text arent shit...pfft

sweet thc listerine strips
