@Ozone69-Nowhere for the pressed oil to go to and you'd want it separated from the impurities. I take my hash and toss it in a unbleached coffee filter or empty tea bags and press it in the hair straightener. I bought a sharpstone pollen press about the same time I got into pressing rosin and it has been left, unused in the box! If you are going to squish hash, squish it with parchment and a hair straightener or a rosin press.

Dont get me wrong, I love a good hash. I just like mine in edibles. That is the one thing I like about canna, there is no wrong way! If you find a way with a pollen press like you stated, please share your findings!!
