Habañeros; Where are you!?

It has been a week since I planted the Habañero seeds, and there are no signs of sprouting. I am assuming that means the temperature in the room I put them in, is not high enough. Since I cannot spring for a warming mat, I have moved the tray to a less convenient, but warmer area. The outdoor forecast for this coming week looks rather promising too, which means lots of sunlight streaming into the mini greenhouse. Crossing my fingers for signs for growth!
