Okay so I'm trying to extract from some MHRB, and I'm not getting anything on the pulls.

Using 200g MHRB in 200g LYE/1200ml water and using naphtha for the pulls then freezing, not getting anything? Any ideas?

Have you followed a tek, and if so witch one?
Do you get anything else (like goo or non active stuff), or just absolutely nothing at all?

Is this your first extraction or has this procedure you used worked for you before?
Do you use salt?
Do you know if the MHRB you used is OK?
How does it look, color of solution and naphta.
Have you done any defat stage?

If you give more info we might can give some advice.

No tek, this is what I have always done.

Has worked without problems before.

Never used salt.

Yes I used the same MHRB for the last extraction and got over 1.5% yield

Solution in clear and naphtha is clear.

No defat I don't think so.

I noticed there is A LOT of spice in the top layer under the naphtha, perhaps an emulsion(never had before) in a red/cloudy layer. Jungle spice?

Perhaps I need to double the amount of water? I just read a guide where they used

1g/1g/15ml lye/mhrb/water

I'm using
1g/1g/6ml

But has always worked well in the past, just have to do a lot of pulls.

Just got some Xylene incase this batch of mhrb is low in n-n-dmt, I heard xylene
will pull the other alkaloids that naphtha misses?

Perhaps it is the temperature?
Keeping the jars outside and its been getting pretty cold like low forties at night.

Uhh yuh. 40 degrees is almost a freeze precipitation. Warm it up, roll it around, and separate. Also how much solvent are you pulling with? You may want to evap half then freeze.

Doing what you said now, using a full half pint of solvent.
