What are the pros? No problems
What are the cons? None
Once i learned to start early and not drop all the seedling on floor I have no trouble. I plant around Jan 1. I had been sprinkling seeds on top of large soil filled tray and transplanting to bigger pots but I'm just starting in pots now. Put in raised bed last time and I could keep the weeds out better. We make celery soup, and freeze.
