making Smoke Ae reducing velocity or speed of it?

Hi All,

I hope someone is around to answer this and not all of you are at the Show....

I am creating smoke (see pic) I want to slow the smoke velocity or speed down. It is generating much to fast and would like it slower or a bit 'whispy'er' for a lack of a better term. I think an instance is in order, however I could not find the master vault to writing instances. OR where to write it for that matter... Couple of areas to look? Maybe a quick fix on this challenge with some pointers? I was thinking to / velocity 50% yet I am not sure how to write it, or if that is what needs to be adjusted to gain my desired 'whispy or slower rising smoke?

Thanks in advance,

NC
