I get the pod with worms & chow in it. All you need to do is keep the pod upside down, tilted and in a fairly warm location. Let them grow to a bigger size, and then take out what you want to feed till all gone.
The 500 with separate chow is where the work begins........where to keep, chow is sticky like peanut butter, I couldn't grate it, worms were getting smashed, etc. etc. Maybe someone else can give you their experience.
As I said, hornworms work the same way - so my greenies in the pods should get bigger in 3-4 days.
