I can only seem to pull -25hg max. Im at 2400 elevation and have double checked all possible leakage areas, should i be happy with 25 or is there something more i can do? Im running a 3CFM 2 stage pump. Will shortening my vacuum pump hose help any?
You are at full vac, or at least close...

Subtract approximately 1” of mercury for every 1000 ft of elevation...

I'm in Colorado..
Full vac is -22.5 at my location.

Hope this helps.
Happy Extracting!

Just picked up a QP of Catpiss to try this on, saw some big glass cones for a decent price @ my local smoke/glass shop.I have big bottles of butane in the shop but I didn't think about vacuum.I have a pump in La that will pull 28 In of Mercury but if a freakin shopvac will work I have a killer one.Sub'd....

im wondering if anyone can direct me on the best way to purge wax that has been in block form for a few weeks now. it was done on a baking sheet and then just sorta folded over itself to make the block. so there are layers when you break a corner off to look at it. can i purge this and whats the best way to go about it? im hoping to get some comb in there but i need some direction please and thank you. i know i will lose a bit of weight but its just a bit to wet in the "crumble" and it flames up a bit, so theres gotta be butane in there.

hey guys, i'm a beginner to this process and found this thread really helpful. was wondering if anyone knew how long i am suppose to hold the purge for?? someone told me that if you hold it too long, it can ruin the product. i was told to vacuum purge until the product muffins completely and de vac. and continue to repeat that process

There is no set time kreal, I've had stuff be done in as little as 12 hours and some that go days.

i was wondering if you could tell me what i'm doing wrong. Last batch i had turned into permagoo and this stuff is turning out dark, more solid though. i make sure the material as clean as can be (no waterleafs/no steams) and i'm trying to stay with low temperatures but i seeem to be doing something wrong. HELP

Sounds like too much heat. How are you providing and controlling it?

Usually I don't ask questions because I know it's on me the effort to read and learn, however, I'd appreciate an answear since I'm about to harvest and running out of time... Its my first time on bho.. so.. follow me:
'Fresh product' is right after the harvest or right after the process of drying and curing as usual?
then, do I freeze it before dumping on butane? do I freeze the butane can too? the container as well?..
ok.. couple of minutes on butane.. then filter it.. so far so good.. now.. after purging the butane in a 115-130F water bath..
(I dont have vaccum machine), what is the ratio between bho and alcohol(iso)?
Add alcohol, stir it a little, then Freeze for 48h.. Finally, purge again in 115-130F water till no bubbles and let it cool.. then gg?! thats it?! Thanks :]

fresh is not dried

i would dry it let it get bone dry
then pack your tube
freeze your tube with material in it over night alot of people freeze the cans as well
then after it has been frozen over night blast it

and i would try to find ever clear if you can its polarity is better for winterizing and after you poured your everclear and bho mixed through a filter on to a pyrex you wont see bubbles like in the vac chamber, the best way is to put it at 110 to 115 with a gentle breeze over it and you might see some white water stuff, its just water wait for it to evaporate out.

hope that helps

Fresh product to me is straight from cutting and trimming, and we extract it fresh frozen. It produces a delightful aromatic extract, but you have to process a lot of material for the same amount of oil.

It is lots faster and easier to remove about 75% of the water and extract at that point. It requires processing less material and the montoterpene content is still high.

It is easiest and fastest to dry the material to 10/15% moisture content and extract, but many of the monoterpenes leave with the water. For oral consumption, where you will decarboxylate later and lose most of the monoterpenes anyway, that is the most efficient.

When running fresh frozen, we break up before freezing in an air tight container, so as to not coat the trichomes with ice and also freeze the butane to 0F.

About <10:1 ratio of oil to EtOH.

Well.. Really nice information.. appreciate that..
Then, does it mean that fresh frozen bho wont have much THC since it's not decarboxylated?
Should I harvest and decarboxylate in the oven for 1 hour at 240ºF (as I read out there) to reach this 15% moisture you mentioned?
I mean, I dont want to w8 over a month to dry and cure as usual '-'..

I haven't had a lot of success using the methods that i tried so far in the 5 or 6 runs ive done, and was thinking of trying fear/olds tek from tokecity because ive been trying the same thing over and over and am having no luck, so i thought changing it up might work for me. Part of their method is oven for 20 minutes between purges - anyone else do this?

Completely strain dependent.. IMO..

I bought a toaster oven when I first started extracting for this purpose..
Don't use it for anything else though.

Man, I've purged so many micro runs with that thing...

I still use it, depending on the resin's viscosity level.

The toaster oven is much more efficient than your regular oven..
Also, your kitchen oven is probably like everybody 's... A bit dirty.

The T. Oven will provide heat from the top and bottom.
This may be your solution goalie.

One more thing on the toaster.. Is able to go as low as possible..

&#8221; keep warm&#8221; setting should be 120° ish...but double check with your IR temp gun.
Once you find the sweet spot on the dial , mark it on the knob, so you know exactly where 120° is on the dial.

goalie give as much detail as you can on the whole process, plus starting material and put pics of the finished product if you can, throughout purging is cool too...

why do you feel it was unsatisfactory? And what are you looking for? (I read most of your posts but didn't really get a clear picture, just bad yield?)

Ok i will use the last run i did as an example and include some pics that i took. The reason i feel it was unsatisfactory, is because when i had what i thought was "shatter" and dabbed it, it sizzled and crackled on my nail, and maybe im wrong, but i thought that this (at the time) meant that it was not properly purged, so i took this "shatter" and put it back on heat and vacuum, and it reacted and turned into a really waxy crumbly type consistency, was it underpurged still? I have no idea because im still trying to learn. Please note that on this run i attempted to vacuum RIGHT in the chamber, which turned out to make it much harder to scrape. Also using a round dish made me lose some im sure because i couldnt scrape it all. In future i either need something nonstick and safe to spray right onto, or i will have to go back to scraping onto parchment or nogoo pads. So i took this material, which was about 9 grams of some bubba kush iirc, and i let it get really dry just by leaving it out at room temp, and i broke it up and put it in the extraction tube and put it in the freezer along with a can of colibri london butane. After it got cold I sprayed the butane through the tube until what came out appeared clear, and i took the butane in pyrex and placed it into another pyrex with hot tap water to purge. When there was no longer any liquid moving around in the spray dish, i wiped the bottom and put it inside the vac chamber and vacced it, then when i couldnt remove it as one piece i scraped it with a razor blade and put it on a no goo sheet and continued to vac + heat it. No pic of the last state of waxy/crumbly sorry pics here - http://imgur.com/a/m0jxV
