I was repotting a few of my seedlings and decided to show of some of the roots. These are close to a year old. They were getting some light from the edge of the cup. I also have not ever trimmed the roots to these. They are all natural. I don't even think I've pinched the tops. I need to keep better notes on my stock rather than trying to remember each one.
This one suffered a little sun burn last year but has recovered quite nicely.
