You need a fan on them, regardless of how cool it is in your room or not the fan provides fresh air flow to the plants and helps develop thicker stems & thus more adequate nutrient & water absorption. Also, how much water are you giving them? Not giving them any nutes right? It's too early for that. For now that 250 w cfl light will work but i'm telling you it will not work for two plants, you're going to at the bare minimum need 7 or 8 of those lights. A convertable MH/HPS ballast system works the best, can get a 400 watter for around $150 shipped. You can do it with cfl lights, but it's very tedious and can become dangerous & a nuisance as well. I know from personal experience.
