The only possible way to alter the "flavor" (scent) of a flower from a cannabis plant is during curing like mentioned above or you can use smoke flavor-altering bongs.

This is a fact. Plants do not absorb flavors, they create thier own. If it were any other way around, imagine what hydro-grown bud would taste like! Have you smelled some of the chemicals used in hydro? Holy nastiness! If my bud tasted like Tiger-Bloom smells I would stop smoking...

Personally I'm in love with curing flavors. I usually add a small piece of lime and lemon to each curing jar. I wrap them in a little paper towel so the juices do not cause mold. Place the lemon and lime on the BOTTOM of the jar before the bud goes in. Any mold that does happen to form will do so on the paper towel first and I can react accordingly. So far I have never had mold.

Now as far as taste goes, no the smoke does not taste like lemon-lime. BUT it does smell like it!! BIG TIME TOO! Upon exhaling you can taste it SLIGHTLY but I think that's just from the strong smell...
