yea same here, except mine was more like 2-3 weeks old. i litrally ripped all the roots off. 3-4 months later and it has grown. didnt get to full size because i stunted it so much. i acctually harvested it last week. it was a runt, but i got 10grams dry of it. i didnt expect to get anything.I have transplanted a seedling that had its tap root snap off. did fine.
