Non sterile Cattleya seed

[Bell_bella]

I got myself this cattleya seeds this afternoon. It is still with it's matured pod. (image) I kept them with me right now, in my dorm. I've folded them inside the wet newspaper.

Is it safe? since I have to wait another 8 hours for them to be transferrred in a sterile condition. (laboratory)

I plant to culture the seeds as soon as I prepare my media.I heard that it can stand only for 1 to 2 weeks. What should I prepare/do? since this is my first time in Orchid micropropagation.

thanks
