Hey @MumenRyder , so when I germinated these I did so vertically by putting the paper towel flat into a ziplock and hanging it from the pole in the top of one of my tents. This promoted straighter tap roots as they automatically want to grow down. As for leaving them too long I would say you could check them once a day. The seedling has enough energy stored to keep growing well past shucking it’s shell so it will be hard to leave them too long really if checking daily. After that I just make a hole in the coco with a pen and put the seedling in, then squeeze the seedling bag to push the coco in and it closes the hole around it.
