yeah i had one i forgot about germing and the root was about 6 inches long!!! with no shell. i just planted it anyway and a week later, looking great (better than the other 4 of the same strain btw, dunno if the long germing did this or not)
yeah the longer tha tap root the bigger the plant will get..its like getting a head start in a race..but if it grows to big nd dosent get soil or light it will just turn yellow nd die off
