Jeg , some of them did crack, but no long taproots coming out. I just soaked them in tepid tap water for 24 hours.
Vapo69 . I'd be afraid to try it with you cuz I'd probably end up jinxing you. LOL. Also, I don't know if I should be starting anything yet, since I got 2 plants mid flower, and 2 plants mid veg. And that's all the space I have in my place to grow. Isn't there a sort of rule of thumb is whenever you move something from one stage to another, like veg to flower, or flower to harvest, or seedling to veg, is when you start something else?
So I can only think of 2 things.
1. The environment is either too humid or too dry. I even got a aquarium temperature strip and it's saying it's about 78 F in there. So that should have been fine.
2. The seeds are bad. Like the guy you sent me these F1 seeds, told me he can't really know if the source of these seeds are reliable. I'll give it till Friday. If nothing happens, I'll tear open those rapid rooters and see..... and if it's still a seed or whatever or rotted or whatever, I'll just start over with seeds that I bought. This is just for practice. Thank God!!
