Poly,
I found these bags on Amazon. They're made for weddings and such. Not expensive. I put them over pods that are nearing the end just in case I should miss their cracking open. I found that if I put them on too early I have occasionally had mildew build up and ruin the pod. I do overhead watering each day so that surely contributes. Overall they have worked well for me. I write both parents on the hang tag and put it in the bag with the pod. When I harvest all I have to do is snip the pod off the scape and I'm ready to go.
