I don’t know I fill up a QT jar its 53 grams give or take. I use 12 ounces. Once you use the 190 that’s it all your oils in it You can do more than one wash. I don’t. You need to read through @ReikoX thread it’s how I fucked my way through it. I’ve only done this oil I’m doing. Making cold evap rso seems fairly easy just don’t over decarboxylate and degrade your THC %. You want to nail it on decarbing if you are doing a cold evap. Your oven and stove trial and error. I do my flower laying flat on baking sheet 240-245 for 43-44 mins. Its one of these things you muck your way though.
I would tell you not to over complicate it, but we know that’s not going to happen.
