Yep. @Roguelab’s points are valid AND you should start with EtOH.
When distilling (recovering), temps can’t go above boiling point of solvent till solvent is gone. That’s the whole point of how/why it works…
You can boil water in a paper cup over an open flame…
If you call the process “distillation”, all your search hits will be for the wrong process.
“Distillate” == distilled cannabinoids around here.

Edit: important exception. Recommended reading… Distillation controllers with both temperature and power control (implements well for spd too)
