Q: Does anyone know how it works?

Soak the seeds overnight, then rinse them twice a day with filtered water. Place in a dark place or cover the jar with a shade cover until the last 5 days or so when you let them sit in a sunny window and let them turn a little green. I rinse and dry them in a salad spinner, then store them in a container in the fridge to store them away.

Q: Is there a way to prevent the lids from rusting?

These are ABS plastic lids with wire mesh screens that will not rust. Other stainless steel lids are prone to rust after a long time of twisting open and touching water, this one will not.
