Rosin as gwheels explained was perfect. Just hella variables to yields. Strain, how dry, temp, squish length. too hard to tell I’ve seen 10% And also seen 30ish%. You’ll just have to try lower temps at longer times which personally I go for quality every time then quantity or I’d just blast it in a bho run imo. Can also Higher temps for shorter times figuring out your strain/plant. I also like the 190 area can give a nice yeild but great quality just about every time! Can also throw in the dab containers and hold it between the plate and whip it up for a different consistency!
