So, over a week ago, I started to grow tomatoes from seeds using topsoil, specifically Scott's premium topsoil. After realizing it's full of crap, bark, sticks, etc., I restarted today using Miracle Grow potting mix. Is this mix efficient at starting seeds, or should I invest in the starting seed mix? It's only been a day, but I hate looking at the plants, thinking that nothing is going to emerge.
And, additionally, do newly planted seeds require light to germinate?
Thanks.
