TEK A/B first time need help!

[honeythewife]

Working on my first attempt at extraction and doing A/B. I’m on the stage where it has a fan on it to evaporate half off. How long is this supposed to take? It’s been 12 hours and I’m not seeing much difference. I hope I didn’t screw this batch up.
My husband says I am cute but I’m no chemist!!

Just to be sure: is it naphtha what you are trying to evaporate?
