Re: how can i make nakhla smoke less harsh?
I use 3 CH nats on a KM bowl and I found that alot of it depends on the way you poke the tinfoil.
Start with a normal pattern, but use barely any holes. Then start the session and when the smoke gets harsher, poke more holes and purge it. Repeat as necessary. This always works for me and I never get any harshness.
Also, make sure your not burning the shisha.
