 STB Tek...........very low yield

This is my first post on the shroomery........here goes
So SWIM ordered a good deal of rootbark from 100herbgalaxy, a source which has received a good deal of praise from some very respected members over on DMT Nexus...........
He followed roughly followed Noman's tek........here is what SWIM did on a 200g MHRB Extraction
1)Dissolved 200g of 100% lye into 2500 ML of filtered water
2)Added 200g of MHRB powder, allowed rootbark to soak for about an hour, according to instructions
3)Added 400 ML of VM & P naptha (SWIM's container was very wide, so used more naptha to make it easier to draw off)
4)Allowed mix to sit for 24 hours, agitating periodically by turning jar end over end and allowing mix to seperate
5)Drew off naptha with a turkey baster and placed into flat glass pyrex dish w/ lid and placed in freezer
6)Next morning was greeted with what at first look seemed to be a pretty good deal of white spice. Poured naptha off and through a coffee filter to get any extract which was floating in naptha.
Yield of first pull was roughly 0.3g. SWIM thought, Ok so maybe the first pull wont come out to a great yield. So SWIM added another 400 ML of naptha and allowed to sit for 24 hrs........Used same method...Next day, did not see hardly ANY spice in dish, maybe 10mg MAX.
Tried to do another pull using less naptha...and alas, very very very minimal yield.
What the hell did SWIM do wrong? Also, the spice which was yielded did not seem to be very potent...Definately threshhold effects, but not even close to previous DMT experiences........

i recently ordered from 100herb and currently doing a STB tek and haven't got that fantastic of yields yet.
i am using the STB tek that nature boy posted and it seems rather fool proof, so to make myself feel better i will blame 100herbgalaxy and say we both got some lackluster bark

You used way too much naphtha to just put in the freezer without evaporating first. 400ml for 200g bark? Doing that will help you get most of the spice in the first couple pulls but you absolutely must evaporate down to 100ml before you put it in the freezer!
I really hope you didn't throw away that 400ml naphtha from the first pull. Most of your spice is in there. Evaporate down to 100ml then freeze. You will see all your spice precipitate.

If one had some sort of fume hood, that would be fantastic.
Of course, barring that, one would want to evaporate the solvent either outdoors, or in a room with good ventilation / air-exchange.
I've seen it done in a small room (well sealed off from the rest of the house, with no present source of spark or flame)... both in a closed room in a pyrex baking dish in front of an air conditioner on high...
I've also seen a similar setup with windows open, and 2 fans (one ceiling, one standing) blowing on the dish.
In cooler temps it can take hours for a few hundred ml of naphtha to evaporate. Lots of air moving across the solution seems to help. It goes much faster if the solution is heated... but that kind of thing has to be done very carefully.
Good luck. BE SAFE.

Yep...there's your problem right there! WAY too much naptha. The spice is so dilute in all that solvent, there is nearly no hope of freeze precipitation. You're going to have to evaporate a very substantial amount of the naptha, and then try freeze precipitation once again.

^^I've never needed more than 3 or 4 days at max to get everything out of a qp of bark. I would think that by a month, the lye is just eating the dmt, could be wrong though. Also, as everyone has said, that is a huge amount of naptha to use for an extraction that small, evap down. Also, I work with very finely shredded, not powdered but I don't see that it would hurt to add some lye to the mix if after you evap down your yield isn't what it should be. I always use equal portions for the shredded and add a couple tablespoons after the third pull just for good measure, but powdered might benefit from some extra lye according to what others have told me.

put some kind of filter over the jar, and point a fan at it.
ive never had a problem freeze precipitation, the solution needs to be saturated though. Try using less naptha.
Ive been using 150ml when working with 100g of rootbark. but i use less water, 800ml por 100g bark. and im using powdered rootbark.
could it be that your basified solution isnt high enouygh pH, though that would probably show problems with emulstions.
Letting it sit for 24 hoiurs isnt nessesary. If yoiu breka up your bark into tiny peices then blender to try and get a powder. You can just mix with basified solution well for a few minutes. leave for 3 hours. Add naptha, roll the jar around for a few minutes , let seperate. repeat 3 times and seperate to draw the naptha.
Into the freezer (must freee icecream solid) and 12 hours later. lots of cyrstalls.
