I'm growing two autos in the same tent, both in 3-gallon grow bags. I don't want them to get very big, because the tent is only big enough for one. :P
I started Plant A on 27 Feb. It took ~5 days to grow a tap root, and then I ended up dropping it too deep into the starter, so it took a few days to "break ground."
Plant B was put in paper towel on 5 Mar and had a tap root on 7 Mar! Maybe she senses the competition and wants to catch up. 😄

Plant A is now "in veg," so I made her a new entry in week 2.
Plant B is a little slower, but she'll get there...
