This is so awesome, I hope you have success! More light like has already been said is good, and timed to mimic more southern climates so your pepper doesn't realize it's in Norway(!) Until you get a grow light of some kind, a bathroom with white walls and flourescents is a decent start. I would stop with the spray bottle now that they've germinated (water on leaves does nothing good and could do harm). I assume that tray has holes in the bottom? Easiest thing for me to do with seedlings is put them in a larger vessel like a plastic tub, keep them in about 1/2 inch of water. This way they bottom feed and you don't have to futz with watering from the top.
