Volute of Vapor
There is a bunch of convection vapes prefering a fluffy load cause the better the air move through the load the better it is heated (at least the more evenly). MiniVap is one of this vapes but the Touch could be used like that for more a tasty session than a cloudy session...works very well too for me.For what it's worth, there's not a single vape in my signature where packing the load was not beneficial.
For conduction vapes it's obvious and easily explainable (less air between plant bits = more conduction) For convection it's less intuitive but if you don't pack hot air will just take the path of least resistance and flow around the plant bits without having time to extract anything.
Of course if you pack too much you'll get other issues like tunneling etc... Just find the right balance, like with everything in life.
Although I agree I prefer habitually a slightly tamped load for bigger clouds and shorter session.
Tunneling happens more with a loose load imo..., with dense packed load I get more hot spots and slightly worst taste.
Did I remenber there was a vape designed for herbs spinning while hitting for a true convection heating(maybe the one from Eerlectrics deigned for flowers)?
