What would be the best kind of root bark to start with on first project? Are all types of mimosa plants equal? I was thinking of starting my first extraction with mimosa hostilis.

Thats the best. Barely any plant oils. Easy to work with. High %. Negligent amounts of NMT.

I have read various amounts of pulls from different teks and peoples own experiences and I know there is a lot of things that can affect it but just interested to hear a general consensus.

I did my first extraction using CYB's Hybrid salt tek and from 50 g MHRB I got a total yield of roughly 980 mg.

This was from 5 pulls. The first 2 pulls yielded 680 mg between then, the next 2 pulls yielded 300 mg between them and the 5th and final pull yielded basically nothing apart from a tiny waxy layer with some minute crystals.

The first 2 pulls were incredibly milky, the 3rd pulls less so and was almost clear, the 4th pull was clear/yellowish and the last pull almost totally clear.

In future is it worth doing a 5th pull? Is the "milkiness" a good indicator of how loaded the pull is?

Really interest to hear other peoples thoughts and whether I should just do less pulls.

I do 3 shaky hot 50ml pulls on 100g of mhrb in a litre jar using the max ion tek and I have found this gets all the goodies.

the only way to tell if its worth doing more pulls is by doing more pulls, since you can reuse your solvent its not really wasting anything.

Cool, thanks for the reply. Next extract I will do 5 again and see what comes out, if the 5th doesn't yield anything worthwhile then I will cut it down etc until I find the sweet spot.

I am guessing different batches of bark can make difference too?

that's what I did.

im not sure the variation in yield between batches would be enough to make a difference but its always worth a try, you don't want any Magic going to waste.

I always do a 5th pull separate from the rest just to make sure I have got everything. In a recent larger extraction I was glad I did - for the first time, there was still some in the soup: 0.8g!! So I am about to do a 6th pull, and possibly a 7th...

Always worthwhile pulling until you can't pull no more! (and no, I am not talking about your internet habits...)

Cheers,

What's the longest you have left between pulls? Just wondering how long the "soup" can last in the mixing bottle.

I usually do 3-4 naptha pulls, then 3 xylene pulls - I extend the duration by about 8 hrs each time. the results are an array of crystals ranging from large and white/clear to small and orangey/red.

I've left based MHRB soup with xylene on top for over a year in a jar. I just made sure the jar didn't look like it was cracking every couple of weeks/months, and gave it a shake at the same time.

I just recently pulled the xylene and am doing a sloooow evap it smelled highly DMT-ish and was bright yellow. Wondering what it will yield - It was the 3rd xylene pull after 3 naptha pulls off of 100grams MHRB - STB Tek

2, but I use Toluene.
1st at 24 hours after basing, and another 24 hours after the first pull.



Woah! that sounds like a lot of effort.
What is the reasoning behind the preliminary naptha pulls?
To me, it would seem to make more sense to just do the xylene pulls, and later recrystal to separate your alkaloids (if that is the intention).

I use normal smoking pipe with 5 screens. I don't weigh out.i put about the size of a nailhead in.i take one sec pull.hold in, blow out.then I go slow at first, then pull hard at end.hold in for 3-4 seconds, and breakthrough everytime.so 2 pulls

I'm fairly confident that the OP was talking about "pulls" in reference to adding non-polar solvent to a basified extraction solution.

The general consensus for smoking on the forum seems to be: get as much as you can in as few tokes as possible. A full dose in one toke is ideal.

To answer the OP's question: I always pull until it is no longer yielding anything, then do one more just to be safe.

tks for informing me of such

I usually work with 100gr. of bark each time.
I always do a big pull first with lots of warm solvent. Like 100-150ml. Then I do two more with around 50ml. each. And I take good time for that. Shake maybe 20 times over 24 hours or so.

My yeild is usually around 1.5-2%

I only do 2 pulls. 2 400ml naptha pulls. I let my jar(s) sit for over a month. Then i add 400ml naptha. I then massively and spastically shake my jars several times and let them settle. Ill pull the first 400, and then put in the second 400, shake vigorously. Normally, the second 400 doesnt grab anything at all, i do it as a precaution. I save the two 400mls seperately for later jars. I keep using the first 400 until it reaches max solubility, then i use the second 400 to do initial pulls, and get fresh 400 for the second pulls. Its very effective and leads to not ever needing to waste any naptha, especially if you just decide to reuse the original 400 after freezing it. Hopefully that made sense to you.

Great method!

Shaneduddy, how much do you use in your xylene/toulene pulls? do you think 1 liter for 2kg is sufficient?
then when you recrystalise your goop with naphtha is it warm or hot? and do you stir it around? I use a wooden skewer but I'm worried maybe that mixes the impurities into the new naphtha.

I use about 150-200 mls for each pull, but I do that for ~250g of bark.
No clue for doing a giant 2kg batch. Any reason for such a big batch?
I generally use a stainless steel spoon.

basically I have a had a lot of difficulty finding safe spaces to perform extractions (and had many many failures)
I essentially want enough that I would not have to take the risk again for a long time.
I use dimitri pseudo-religiously.


also why the 24 hour break in between pulls?

I usually do 4 heated pulls using improved STB tek
