Found this on another thread.......also a thread on here said that if you use plain water with a mixture of flavoring (vanilla, mint, cherry ect.) extract and water your plant an hour before you harvest it will add flavor too.
This article is taken from an old timer growbook that i have and i thought i'd share it with you as it might be usefull to some.
"It is strongly advised that any flavourings be applied to only a sample,say a few joints worth.
Being stuck with a kilo of some drab flavor like avocado flavored weed may get to be a bit much,especialy in the bleakness of february.
Do only a bit at a time to see how you like it.
Most flavourings will fade away if exposed to air,so keep any flavoured cannabis in a tightly sealed jar,as a bag wont do.
Suggested flavourings
Bottled essences:
menthol,spearmint,vanilla,maple,peppermint,fruits. (smear some on to a cotton ball and put in the jar)
Real fruit:
lemon,lime,orange,grapefruit,apples.(use the peals only and put a little piece into jar)
Real flowers:
rose,lilas,fruit blossoms and other flowers.(put some in the jar)
Spices:
cinnamon,nutmeg,cloves,rosemary,camomille.(use a tea bag,cut a corner off and empty it and refill with spices and staple the corner and put in jar)
Spirits:
wine,port,sherry,wiskey.(smear some on to a cotton ball and put in the jar)
Flavouring mediums to avoid
When sugar burns,it burns hot and gives off a hot,black carbon smoke,to avoid a carbon smoke,it might be wise to stay clear of:
any soda pop,
maple syrup or sugar,
molasses,
Anything containing sugar."
