Your article describes winter-sowing. I much prefer seeds sown outdoors this time of year. From my experience, the winter-sown plants seem to be much hardier than indoor germinated seedlings, don't get damping-off disease, don't need hardening-off, and don't suffer from transplant shock as badly. I also don't have the expense and labor of soil warmers, lighting with periodic adjusting, timers, watering, etc. As you stated, some seeds need the cold stratification, too. Mother Nature truly knows what's best, so let her do the work!
