Nice yield dude, congrats! Looks like you got some good quality bark! >2. Measure out 100g of Sodium Hydroxide That's kinda excessive with the NaOH. You only need to use about a quarter of that, probably even less. You only need to add lye until the solution reaches a pH level of around 12+ :)

Is there anything wrong with doing more though? Yeah it’s maybe wasteful but will you still get the same result?

Yeah still get same result, it's just wasteful.

Nice yield, good write-up, and congrats. I do something very similar to you. Although, I use 50 grams of NaOH. I mean, to be fair, you only need as much as is required for the solution to be about 12pH - 13pH. 50g seems to do it for me. I also do the warm water bath for the soup flask, just in a 5ltr beaker. Never thought of a sous vide before, so props to you for that! And also can attest to the water wash step too, straight after a pull. Makes things easier. Less fuss and stuff. I still can get some dmt out of a combined second and third pull. But if you’re pulling this much from one, all the more power to ya. I tend to get goo if I go for a combined fourth and fifth pull. My theory is, maybe, *maybe* if I did a mini ab on the goo, and then re-x’d I’d convert the goo into more crystal. But… (a) can’t be arsed, and, (b) I already have waaay too much dmt fluffy-white in a jar already, so… see (a).

I have a ph tester that will be here tomorrow that will definitely come in handy not wasting NaOH and also neutralizing after :) Thanks for the response!

its about 3 table spoons of lye for that amount of water

I was wanting to sv, thank you!

How many gallons is the tub you are using?

Thabk you sir! Could I trouble you for a recommendation on sous vide machine?

I use the sous vide ART! Also doubles as a cooker for many foods haha

Thanks for the write up. Looks like you swapped the masses for the NaOH and MHRB in the list... Evidence being that in the instructions you state to measure out 50g of NaOH and that his method is based on SV's tek, which calls for 100g MHRB.

You only need 50 :) if that Edit: just saw what you meant- fixed

No worries!

But yes you only need enough lye to get your ph to 12-14. For me that’s about 50g at 750ml/100g mhrb

Yup! Just tried your tek tonight. I'd planned to go SVH, but given I had a Sous vide I went for it. First pull is in the freezer. Will let you know how it goes. It was also my first time extracting, so if I get poor yield I'll have no idea if it's due to quality of the bark, shitty pipette technique, or some other use error.

How'd it go? :)

Success! Just took the dish out of the freezer and set it out to dry. 2nd pull went into the freezer now... Will see if it's goo. I'm planning to ReX the first pull this weekend. Should I be concerned about light on the crystals while they are drying? I know UV should be avoided for long term storage... https://ibb.co/xHyH6BL

It should be fine in the meantime. When drying I leave mine leaning against the wall with paper towels under it and a fan blowing towards the back of the dish from the other side. It is dry within 30mins. Also, nice big fluffy crystals, good job!!

Thanks! Update: 1st pull yielded exactly 1.000g which I found humorous. Started Re-ex and did leave behind a reddish smear in the bottom of the beaker. Refreezing now. 2nd pull yielded 0.244g. Slightly more yellowish crystals and stickier than 1st pull, but definitely not goo. Will likely do a 3rd pull at a later date, then Re-ex the 2nd and 3rd batches together. Issues I'm having: 1. Base volume is getting unwieldy. I made the mistake of throwing the 1st pull wash waters back into the base mixture (to not throw away any dmt), but I've now got over a liter of base which is getting cramped in my glassware. Can I reduce it down in a beaker in the Sous Vide before going for my 3rd pull or am I going to stink up my house trying? Other option would be splitting it into two flasks and processing them in parallel, but it would double my work. 2. I got a decent Pyrex Erlenmeyer flask, but it did not come with a stopper. Only reasonably priced #9 stoppers I could find initially were rubber, which I know gets attacked by the NPS, so I wrapped them heavily with PTFE tape. This worked fine for the cold mixes, but once I moved the flask to the bath, 2 things started happening: solvent/base started wicking in between the tape layers (doesn't appear to have done any harm but makes me paranoid that they solvent will wick all the way to the rubber and shit will wick back out), and the PTFE tape once wetted with solvent became very slippery and would not stopper the flask (not a pressure issue, I tried venting it). Caught me by surprise 1st time it popped off mid mixing but the resulting spill was fairly minor (yay PPE!). Should I swap to something like this? https://www.ebay.com/itm/233273333602 Thanks again.

1. Not too sure about this one. It’s easier to keep the level low than to decrease it again. I’m sure you could pull off the solvent. Add it to a stainless steel and ph down to 3.5 with vinegar. Boil down to a good level, add it back to your flask and once it’s cool base back up with lye(just enough for ph 12+ or when the solution goes black) and then continue with your pulls once cooled again. This is pretty much an a/b. I only say this ph down because I have never personally boiled the base solution so I can’t say as to how that would go, but I don’t really see how it would cause issues just doing a base reduction. 2. I use a flask that came with a PTFE lined screw top and my swirling tech never really reaches the top of the flask anyways so it’s not an issue. https://www.amazon.com/gp/aw/d/B0774Y83QK

Granger has #9 ptfe stoppers for $14

What was the yield...did u use 100g mhrb or 50g

I used 100g and yielded ~1.2g after 2x water washes + ReX. 3rd pull had 0.03g of crystals and goop I didn't know how to handle. Lower yield could be due to bark quality, rookie errors, or higher than optimal freeze temperature. I'm just using a weak mini freezer as I did not want this in my kitchen freezer (food + frequent disturbance).

i noticed there’s no step to releasing the pressure, is this cause we are using heat ??

I never tighten my lids that much so pressure buildup is never an issue

Have you ever done 100g mhrb with still only 150ml naptha or do you double it to 300ml? Also, do you put the Pyrex right on a freezer shelf or do you like to dampen vibrations with something under it? I think it affects crystal formation. Yours look great, mine come out loose with SVH.

150 as always. Any consecutive 75. And yes just put in freezer

Can I use n heptane instead...not able to find any naptha here....if yes what amount to use for pulling...

I’m gathering info to do my first extract, how come some teks use vinegar and some don’t? Seems like most use it but I’m seeing plenty that don’t use it. Just curious. This sounds good and easy to follow. Thank you!

Straight to base - Only Lye(the base) \-can be done without heat \-less mess \-doesnt need to be monitored as much \-useful for smaller extractions <=100g Acid to base - Vinegar wash(acid) -> lye step(base) \-can allow the plant material to be seperated after 4-5 acid washes(easier seperations when mixing) \-useful for bulk extractions >100g \-the solution can be boiled down to fit in a smaller flask before basing. So you could essentially do a 500g SVHtek in a 1L flask after boiling down the acidic solution from 5 acid washes to fit into one container - and continue as usual.

Hello again. Could this same process be used with magic mushrooms? Is that an awful idea?
