To answer this question, we have to keep in mind several variables, all of which could cause the coil to not heat enough to vape your juice. Battery, device, coil, wicking medium, and juice can all make a difference, and then to throw air flow on top of that. The short answer is yes, but there can be a fine line between too much and just enough for big clouds. To me, the best reference is experience. Try different things, and find what you like. Stick with what works, and trash what doesn't. Every minute spent fiddling with a wick is sixty seconds of vape heaven you'll never get back.
