What will be intresting, is to see its growth pattern and wether or not it will have more Nicotine in it. It obviously has more nicotine in it then a seedling would at the same ammount of days of growth. I..er...well...I've got it experience in growing another type of baccy, if ya get my drift (Back in the day and if i ever grew it now, the wife would hang me), anyway, It seems a plant gets more of it's active constituants after being cloned and the flowers were bigger.
There is one thing of concern though and that is flowering. If baccy is photo sensitive, being that the days are getting shorter could trigger it into flowering. On the other hand, with the plant putting energy into root development it might reset it's timing. If I remember correctly, last year on my sucker crop, the suckers didn't even go to flower even as late as november. So, what I'm trying to say is that there is hope in this.
