Works for me! I did read something interesting. If you need to thin carrots that are close together, snip off the one(s) you don't want, instead of pulling it. That way, you don't disturb the root of the ones nearby. Disturbing the roots can make them grow crooked, which you don't want for carrots.As far as seed spacing, I am so bad. For lettuce, greens, beets, and carrots, I just sprinkle seeds all over their growing area. if they get too crowded I pull out the ones too close to one another.
