I'm growing my seedlings in unmarked jiffy pots, but in labeled lines.
They do occassionally get mixed up during watering (as I take them out of the lines). I've found growing 1 line of tomato, next to 1 line of peppers is very useful. As you can ID which line the seedlings came from due to their leaves! Not sure how many people are using labled lines, rather than pots, but hopefully this will help someone
There are some tomatoes that I'll only be able to ID once they fruit! (Newbie mistake!)
