A bit of butane seemed to shoot out the sides of the bottom of the tube a little bit, but its quite hot and humid right now where I am....I'm new to this so I'm not sure whether I lost butane to the wind or if what I saw was very cold air vapors or something. Might need to try another filter next time....the coffee filter disk I had inside the filter might have been better off as a whole coffee filter on the outside.

I didnt mean an ISO wash to refine the bho. I meant doing a second wash to the weed using iso instead of butane.
