I really could use some tobacco seed
You can buy seed anywhere from amazon to any number of other websites. Also, you can contact your local Farmers Cooperative and get seed for mere pennies. Personally, I look for heirloom varieties to grow, because all of the other commercial crops are already easy to get. If I'm going to grow it, I want to grow something different. Although, I did grow a row of commercial Virginia Gold, just to have something to compare to what's available. It's easy, easy, easy, and I'm surprised more people aren't growing their own tobacco.
