I grind my herb and it works just as well. It all comes down to personal preference.
I also recommend the all glass stem (w/ carb) over the whips for a better taste and easier inhalation.
I've had my Vapolution for about 3 years now.:)
Quit Smoking. Vaporize.
I have not created my own vaporizer YET. I have been using a Vapolution vape for almost 3 years now and I've been wanting to change it up a bit. Just looking for some ideas. Something to get me started.
