<i>The nicotine is a very interesting idea, does it discolor or leave any taste? </i><p>
I once burnt a hydro grow doing this but it was on the same day I switched from 400hps to 1000hps and it was more of a scorch than a burn, leaves a bit too wet and too high a heat change more than the nicotine tea itself...<p>

There is no discoloration nor nicotine taste to worry about...twenty years ago, before the nicotine nazis were around, this was a pretty common form of pesticide, I use this formula on my veggies, and have done for years, but flush or let it rain a couple of times before harvest. I smoke two packs of Marlboro's a day so I may not be the best judge of taste but I grew enough last year to be able to give away several pounds, nobody complained about the taste.<p>

I have also used tobacco to cure my bud for many years now...I spread a rough flake pipe tobacco into a large plastic storage bin and then put my dried buds on top. Let them breathe with the lid off for an hour a day and turn them twice a week... I've never had a mold problem using tobacco to cure bud, it leaves the buds moist, aromatic and increases their shelf-life...
