I would wait until it just starts to crack or if you can crack it with ease.
I am not sure if there is one way that all seeds can be handled, but going directly from the pod to moist vermiculite gave us almost 100% sprouted seeds last year. My fridge is full of seeds already this year and we probably have about 70% harvested. Our forecast is for a cool down from low 100's to low 90's so I think I will start direct sowing all the remaining seeds from EV and SEV pod parents in to cups and pots. This also worked well for us last year and we were able to plant them in time to get established before winter. I am surprised at the quality of our daylily seeds after such drought and hot temps. It has rained one time in 67 days and we have now had 3 weeks in the upper 90's and low 100's. The plants look really bad now going thru summer heat dormancy.
