Hey, i live in indiana, too. Floyd County. where you at?
Anyway, i don't think you're wasting your time. if only half your plant plants survive you're going to get a 20,000 dollar return at the lowest estimate. you probably paid about $400 for that many seeds maybe a little more. that's a pretty good profit.
I grow and hunt ginseng. your plants won't be \"gimp\" the seeds you planted are good. i had the same problem in the begining, trying to over think everything, doubting if i was doing somethin worth while. i finally just decided to enjoy the process and see what happens. you're not going to lose anything. so why worry.
i think you should plant a new crop this year and every year, that way you'll always have a mature crop.
If you just let them grow and leave them alone they'll be comparable to wild. don't over do it. i would just sit back and enjoy.
