Relatively new to cannabis cartridges. Typically about half way through the cartridges use it will become clogged.
I've tried a number of things:
1) Using a hair dryer to heat up the middle/bottom section of the cartridge in order to loosen the oil prior to screwing it back on the pen for use. Works for a few draws, then slowly clogs back up.
2) Using the 15 second preheat function on the pen when a clog becomes apparent. Works for a few draws, then slowly clogs back up.
3) Taking a paperclip through the mouthpiece down into the thin metal cylinder that runs up through the middle of the cartridge, carefully scraping up && out any noticle amount of oil lodged down near the middle/bottom of the cylinder.
** I'll typically store any of my cartridges not in use with their little bottom caps, so that they can sit upright && not on their sides when not in use.
I've read from a few other forums that typically no matter the brand of cartridge, even the top tier ones - they can all potentially clog? Not sure if that's the case, but it's what I'd gathered from the little bit I'd read on other folks review/s of things.
Maybe it's user error <<<< (this is highly probable)
Cheers
