Greenhouse's Lemon Skunk doesn't smell much all through the grow, surprising considering it has skunk in it and it is a very strong tasting smoke. Greenhouse's Trainwreck doesn't smell either until the last couple weeks, even then it isn't too bad and is more of a fruity smell not skunky.
Whatever you do, don't grow Greenhouse's Cheese, that stuff is insanely pungent!
Like Grassified said, lower temps help with the smell too. The more you let soil dry out the more they will smell as well, but dont be over watering just to tone down the smell its not worth it, just an fyi.
Good Luck!
