I have done a bunch of research (of course not enough) on germinating. I'm sure i have it down up until planting it. But all i can seem to find after that is planting it in soil after the root has poked out. I am going hydroponic (bubble bucket style). Question: Where do i go from the paper towel if i am growing hydro? If i am using gravel as my medium, what do sprout in? Thanks!
