Firstly, welcome! I had the same problem. I went a full 2 weeks with my first attempt. When I peeked at her, there was something there, I uncovered it to give it light, nothing. Finally investigated and the seed was still trying to release goodies down there after 15 days… so technically it did germinate but I didn’t have a plant. I ended up pitching that pod, the seed tried to create 2 different roots in it that never made it out, and starting over with a whole new one.
I’ve got my fingers crossed for you that she pops this time but I think the way to go is germinating the old fashioned way like you said. I germ’ed in water the 2nd time around and had great results.
Good luck!!
