i just read this article on rosin tech steps https://cannabis.net/blog/how-to/what-is-cannabis-rosin-and-how-do-you-make-it
is there anything else that would help me get started?
those bags are expensive, i have been using some i got at a local shop. first i used rosintech then i found shobagz and they both have been working for me. what other bags are you guys using?
