Thankful to have read a lot of information here and have decided to try making some bho. Iv come to the realization that I will be making anything from shatter to goo with some butane left. My question for you all is (and this is kinda a hard question) how much butane will be left and will that be an acceptable amount. I plan to take temp to 90 deg and slowly raise till it fogs, then overnight vacced. Not dewaxing this is a simple attatable plan I hope to achieve. Any input appreciated.
