I used that same book last year for my fist ever gardening project - 24 tobacco plants (4 varieties).
It's really good on basic organic gardening info and tobacco - specific growing info like pests and fertilizer. Not so much on curing after the harvest.
Good luck!
So.... how did your leaf turn out? It would be interesting to hear how you liked what you grew. 24 plants sounds like you may have gotten a huge amount for your efforts!
