Those look good! I do not plant it because we have a white butterfly that eats them faster than they can grow. All brassicas are affected by this insect and everything is full of holes before it can be harvested. I think it is because there are so many canola fields close by.
There is such a trouble. But... There is a non-woven covering material that saves these plants from the white butterfly and from the cruciferous flea.
Currently I don't even see this flying and jumping parasite.
