Flasking HELP!

With my last post, some of you said that my seedpod would not be ready until July or mid April. I’m on a bit of a time crunch and I’m wondering, can I prepare my Jar tomorrow with the gel and let it sit until I’m ready to use it? I asked my teacher today if I could come in tomorrow and flask or good seeds, cause I thought the pod was ready…. And I feel kind of nervous to ask if I can do it another day and I definitely don’t want to wait until the next school year :(
