yeah i've seen that stuff.... the link i gave is for home tobacco growers to spray on living tobacco plants to flavor them.
actually no, the link you gave is for home tobacco growers to spray on harvested and cured tobacco. just as you would use tasty puffs.
We suggest applying a Flavor Enhancer to all home grown tobacco, allowing it to fully dry and then applying a Top Note Flavor for best results. Applying our flavors is a very simple process:
1. After tobacco has dried and cured properly ( Consult Alan Daly's Tobacco: Easier than you Thought guide for curing information ), removes stems and shred tobacco into the size you will use when smoking.
2. Place a pound of shredded tobacco into a large open tray and start misting the tobacco with the flavoring while stirring the tobacco thoroughly. 2 ounces of our pre-mixed flavoring will flavor one pound of tobacco.
3. After flavoring has been applied, cover container for 3-4 hours to allow tobacco to fully absorb flavoring, then spread tobacco out on a table or shelf to dry. Stir the tobacco every 4 hours or so to facilitate drying.
4. After 24 hours, tobacco should be ready to use. We recommend sampling a batch to insure that it has dried adequately, if it has not, allow to dry until burns evenly when lit.
those are the directions off the site you linked
