mostly white-ish is what I would expect, with some of the older ones maybe being a little woody/brown. If everything is dark red/brown/black that's not good.

Thanks tsheets:

OK good. When I transplanted a few of mine a couple days ago, the roots were whitish. But I was surfing the net and I saw something about whitish roots being a sign of a problem so it had me a bit worried. But as far as I remember, mine have always had whitish roots when i transplanted anything.

Tsheets is correct.
Healthy, juvenile roots are pure white, and older roots may be a bit tan.

Thanks Tsheets and Josh, I appreciate you guys putting my fears to rest.

Yes, white or tan is correct.
