Interesting idea. I see this "hornworm farming" as a good idea for someone with a small garden that does not use pesticides. Somehow though I just can't imagine BigBonner walking through 20 acres of tobacco with little hornworm containers..
i actually had 2 old men,,,,,buy some of my plants,,, AND THATS EXACTLLY WHAT THEY WERE GOING TO DO with them,,,,is raise hornworms for fishing bait,,,
i asked them if they lived a long ways from me, because i dont want thier offspring,
...i use THURICIDE h.p.c.
and my worm problem goes away,,,
