Sadly I did not transplant or trim the rootball... I did read about that I knew that I should have, and I meant to do that but growth started quickly and now I am a little unsure as to whether or not I want to transfer it. I was concerned the stress would harm the plant and since it seems to be growing well right now I figured why try to fix something that isn't broken. If you recommend that I still transplant even after its been vegging for 2 weeks or so, then thats the way I'll go. If nothing else.. I really wanted to put it into a larger container.

My other concern with that was since there is quite a bit of new growth, would I be cutting off the new roots if I were to do that now? And if so, does that matter?
