Drip Tips with Grant – Vaping Wick – Cotton, Rayon, or Hemp?

Which is the wick for you? This week in our drip tip series, I will be outlining some of the pros and cons of three of the most common wicking material out there today. With unique characteristics, each material has something to bring to the table when it comes to customizing your vape. With the point of an RDA being to customize your vape to your liking, I thought this would be important to go over.



Cotton comes in many types. You have your standard cotton balls, organic cotton, Japanese cotton, and cotton rope. There are differences in performance in these types as well. For instance, Organic cotton- while carrying decent flavor and wicking quite quickly- lacks the density of Japanese cotton. This means that Japanese cotton will hold more juice than it’s Organic counterpart. One thing about all cotton, is that many people find it to have a earthy taste. I count myself among them and don’t prefer to use cotton for that reason. Another trait cotton has is that it burns very easily. A dry hit can be torture and is not very healthy for you either.


Rayon may sound like some toxic, man made material, but it is actually quite clean. Rayon is another name for cellulose cotton, or extruded cellulose. Cellulose is a high heat, fast wicking material made from plants, that I prefer when vaping sub ohm rigs. Rayon can burn, but you get what I call a “warning hit” just before you are about to run dry. With cotton, you get a nice flavorful vape one minute, and a burnt hit the next.I would say that is the number one reason I like it over cotton.. It has a clean, pure flavor after it’s broken in, but doesn’t hold as much juice per gram as it’s counterparts which I would say is a con. If you don’t mind dripping frequently and want great flavor, this is the stuff for you.

Last but not least, we have Hemp-

Hemp wicking isn’t something I’ve had a tremendous amount of experience with, but I have built a few hemp wicked rigs in the last few months. Hemp has a very high capacity for holding juice, I can say that for sure. I never seem to have to drip as much when using hemp as either cotton or rayon. The thing with hemp, is that the hemp I used had a lot of debris left in it from the manufacturing process. I don’t know about you guys, but I don’t like little chunks of woody material in my wick. On several occasions, they even ignited a small amount. All in all, hemp is not something I can honestly recommend, but that is just me.

Whatever you choose to wick with, just make sure that the bane of your existence will be dry hits as a sub-ohm vaper. So make sure that you keep your wicks nice and saturated. Many toxins can be produced when you get a dry hit, and they vary from material to material. Like I said, and like you all know, keep those wicks juiced up and you will never have to worry about toxins. It doesn’t matter which you prefer either, whatever works FOR YOU is the best wick out there. Until next time, Vape on, vapers!
