If you are thinking of paying for ads in a magazine to promote your commercial venture the ads will have to be in every edition and your market is limited, if you are selling only hops which really is only "Milk Bar" money I would give you the same advice as Cocko,
if your advertising is either free or inexpensive stick with that, most of your prospective market will find you here.
Another piece of advice is, make up your own mind which direction you take, taxes and advertising expenses are ball breakers.
