Sorry for the type o I meant to say mod based unit my apologies. I’m wanting to do what we call hot rails with the glass stem off the mirror or table and without a torch hopefully can be more consistent with the proper temp rangeDo you want to use this as a nectar collector, to vape flower, or something else? Understanding the scenario would help, I'm not sure what this means: "a mix based unit". The Splinter Z and other vapes that use stems make the stems hot, but probably not hot enough to use as a nectar collector. A coil and PID would do it. You could use an IH to heat an all steel or glass over steel tube.
