If you really want you're seeds to crack do this. Get a paper towel, wet it, put the seeds in it, fold it, put in a zip lock zip bag, put in a window for a week or 2. It works trust me. Just make sure it gets a lot of light.
Um..Dude, they are cracking right now! In less then 24 hours half of them are showing tails, I am wondering how much longer I should keep them submerged in the water/superthrive/rooting hormone... This is the fastest germination system I have ever witnessed...Anyone out there have any suggestions on how much longer I should keep them underwater?
