Re: How wide can a stem be?
I made a hookah with a 3/4" stem.....ran it with a regular hose and recently upgraded to a razan. Noticeable difference. The draw is rediculously easy....i've never smoked a KM...so i cant compare. One day i'll get a KM. I still havent gotten down the smoking 100% on the one i made, some sessions are phenominal and others the smoke quality goes up and down.
Anywho, let us know what u decide and let us know!
consider making it so u can swap out stem sizes(depending on what u use for a stem) to see a difference stem size makes
