I have been trying to make some decent and good BHO for quite some time now. I use a glass tube 1 is big enough to hold a QP the other is way bigger like holds 1 pound. I have micron screens and coffee filters I use. I pack the tube and wrap it in plastic wrap and it goes into my deep freezer, for a day sometimes longer. Every time I make the BHO though it is either baby shit green or black as a tire. I give it the hot water bath for the 1st purge and then it goes into my vacuum. I don't have the most expensive stuff to work with, but it isn't pure Sh1t either. It should do the job with no issues but I can't get it right. I will post pictures of my equipment and the BHO I have made it aint pretty but it does make some sick ass Moon rocks, I put so much BHO on them I call them asteroids, cause they hit you hard as hell. I know I could get the stuff to do a color scrub but I want it to be legit no some fake crap.
