Temps? Pressure? What parchment (I.e. raw or oil slick)? What micron Filter? Bubble hash > Ground or Whole Flower? What is the optimal process of “solventless rosin”
@cyclopath I want to know thru forum again I will read the files you gave me via data dump when I am back to my desktop tomorrow but for now I want user based opinions not fact.
opinion?
it’s all about the moisture content.
you’re really doing steam distillation of your essential oil.
facts? ain’t no such thing as “can’t be scaled” 
or maybe I’m getting those two confused again?
Well this is my oppinion…not a fact…but you squish it…and thats not a solvent…
(there were background screams…but bro terps are solvents!
Hey mannn dont forget the universal solvent water!!..)
Here is some info that isnt hot air!
You can make rosin with hot air?
indeed you can, like a vapeorizer with a condenser. yeilds/product suck though… Do you remember the direct sublimation of canabinoids from plant material thread?
