Old man needing some tips to improve STB yields.

Hey all. Been lurking on here and some Reddit forums for the past couple months. I took the dive and began my journey in extraction a couple weeks ago with dmt and am hoping to be ready for a cielo for my Pedro’s in January. I’m on a sabbatical from work and am trying to jump head first into more drug gardening and extracting. I have all the time in the world to mess with the process if anyone would be kind enough to help me out. 🙏

I’m having some trouble getting the most out of my pulls and feel like there’s definitely ways to improve my yields, or save what I currently have going on. I have never come close to 1g for 100mg of bark powder. On the most recent round, I’m getting 50-190mg per pull. I know I’m missing something, or there’s extra steps I can take to recover what’s still in the sludge, water washes, or naphtha. I just don’t know how to identify which process I need, and at which point.

I have followed u/CADjunglist Mini STB tek, on Reddit. Essentially, salt and basify water, mix with bark powder, add NPS, swirl, pipet to water wash, freeze precipitate and scrape. Having tons of fun in the process, reading and learning more about organic chemistry. Still, the results have been lacking for me, and I’m certain the DMT is somewhere in the stuff I have from the process.

Aside from needing more lye to reach a +12 ph, the only thing I altered in the tek, was to keep all solvents, bases and washes in warm water baths throughout the process. I didn’t heat anything on the stove, just warm tap water because the room I’m working in is on the cold side.

This round the sludge was too think in the flask and I had to separate into two mason jars and thin out with more danger water. I didn’t realize how thick it was until I attempted to do the first pull and nothing separated. Since then, I have used 20-40ml of naphtha for each pull. The first two produced 46mg in one Pyrex, and 191 in the second (each with around 20-40ml NPS in an 11 cup Pyrex tray). The second pull produced 154 and 181 respectively. Each of these pulls produced beautiful easy to scrape crystals, getting gradually more yellow with each pull. Albeit less than what I was anticipating.

I just pulled the two trays from the freezer for the third pull, with the temp set to -5 and a wet saltwater soaked towel wrapping one tray with the other set on a shelf normally. The towel wrapped tray has visible crystals and goo on the bottom. The non wrapped tray had maybe 1-2mg if that. There was practically nothing on the tray.

It seems like my first pulls are always the weakest and then later pulls are more fruitful. But this round threw me for a loop. Is there anything I can do other than continuing to attempt pulls with naphtha? I feel like the initial mix that was too thick might have messed things up and has trapped the goodies in there somehow. Do I need to a/b this thing somehow? If so, what’s a good reference point for the steps. I suck at finding the right search terms…What should my next steps be?
 
The base solution should be very liquid in consistency to ensure the layers are able to mix easily through one another. Add more water if needed to form a freely flowing soup. Then add more lye, go ahead and push the ph all the way up to 14, mimosa should turn jet black as a good indicator it's fully based.

I suspect where you may be running into issues is the step of swirling the solvent through the base soup, you really want to focus on thorough mixing of the layers (don't shake it! emulsions suck!) make sure the container is well sealed and roll it gently end over end for a 2-3 minutes, then let it sit and separate fully, then roll it again, and separate again. 3-4 rounds of this mix and separate process per pull should assure effective alkaloid migration.

A good liquid consistency, high ph, and thorough mixing should help a lot in coaxing out those precious alkaloids. Keep us posted on how it goes. (y)

This is very helpful! Thank you. I think I felt like I overkilled on the first round, too much NPS, smirking more than needed, and so on. I guess I dialed things back too much.

I will say, the current consistency of the soup is liquid and the color is black. I guess my concern is that my initial naphtha add disappeared entirely before I realized how thick it was. After thinning it out with more basic water, it seems to be going normally in terms of separation, but is the initial attempted pull still stuck in there? Did I possibly use too little NPS each pull, thereby leaving big chunks of dmt still in the soup?
 
Subsequent pulls should grab any trapped solvent/material. When in doubt I say just keep pulling till it has nothing more to give.

It's possible you just have weak bark and that's all there is to give.
