I used my coco pod when my seed didn’t pop and the second one came through just fine. Make sure the environment is warm. I feel like that might have been it, to chilly for the wee one in the coco pod.
That’s why I germ mine outside of the Grobo in a warm spot, on top of the fridge, for me it was in my bathroom with the door shut, was like a small sauna in there at times when the heat comes on lol. But that did the trick for me. I mean before the Grobo I always germed the way I do, just worked so why switch for me anyway
