That is a good start but you need the proper equipment too. Can you use a glass or stainless tube and canned butane still? yes. Does it leave can oils and other contaminants that you don't want to smoke in your oil? hell yeah! Honestly, it just isn't worth doing if you don't have the closed loop, vac oven, and all other proper equipment to go with it which can be big money. I think ice wax to live rosin is a lot more realistic for home growers or small guys.
That sounds fantastic! If you are in norcal, come use my press! lol I really want to get the bags and try it myself, I am just nervous to commit crop to it given that I have no experience with the process and then get shitty results. Maybe I'll just do a small amount for a small test run with some cheap bags.
