All vegetable seeds can germinate only, when the soil temperatures stay in their preferred range. Species, which require a lot of warmth may need more warmth, than your home provides. Please keep in mind, that the temperature of a soil must stay above the minimal acceptable level all the time. Cold nights often interrupt the sprouting of the seeds and cause problems with a germination process. Using a seedling heat mat is the cheap and easy way to provide the optimal conditions for your vegetable seeds.
Heat mats are rarely necessary for starting plants with the lower temperature requirements, such as tomatoes. However, you can speed up their germination process, when you provide more warmth for vegetable seeds.
