Hello. I see your just starting. Yes your seedling could use some heat. A seedling mat can get pretty hot. It's supposed to have a heating control inside it but they don't always work right. I like to use one of those oil filled heaters. They don't take up a lot of floor space. and they don't get really hot unless you want them to. If you keep a small fan blowing air around they don't get that hot. Good Luck. Chuck.
