Cybs' Hybrid 1st pull yellow, 2nd pull brown

[Johnbip]

1- Before to start the tek I did an extra step to increase yield.
I first mixed the water with bark powder, heat it to let the water penetrate the wood cells, then froze it once.

2- Acid Phase
I add vinegar as the receipe suggested, and I also added citric acid (Ph is much lower) after 1h of double boil. I let it double boiled a few hours before to add the lye.

3- Salting + Basification
I added the salt 30g/100ml water, then the lye.

I did most of the tek on a doube boil, quite a high temperature. Defenetly above 70-80 degree celsius.

4- Non Polar Solvant
At the last stage when we add Naphta , this is what happened :

1st Pull
I added 50ml of naphta, heated in double boil, mix it a few time, heat it again, I pulled back yellow naphta,

2nd Pull
I added 50ml and heat it, mix it, 10-15 min later pulled back brown Naphta. Does someone know why the Naphta is brown? does it means I collected some MNT with it? is it safe to smoke?

3rd Pull
Added 50ml of Naphta, heat it,mix it. Waited 30 min or so and pulled Yellow Naphta. The Naphta seemed loaded with DMT.

4th Pull
Added 50ml Of naphta, heated it, mix it. and let it sit for a while, Naphta was much clearer than earlier pull.

Did someone tryied this tek, does it look the same?

1st Pull
420mg of precipated crystal. I poured Naphta in another container to evaporate. I will update the amount of DMT left

 

[Johnbip]

In total I pulled 0.815mg of DMT from 50g of MHRB, which is 1.63% of extraction.. It is the first time I am extracting so much of it. Usually i am extracting about 0.80%.
