Hi Ddawn, nice to meet you! Welcome fellow gardener !
For many years I have started tomato & pepper seeds in the house. It saves me from bringing soil borne diseases from the nurseries; and, it gives oh so many more variety options. I used to start my seeds about 12 weeks before planting in the garden. Not now. Now I start seeds 8 weeks before planting. The smaller tomato plants produce tomatoes just as soon as the 12 week plants do. Important, garden soil must be warmed up or your seedlings will just sit there until it does warm up. Tomatoes don't grow in cold soil.
