Good luck with your grow. There is a learning curve and you have to ride it from beginning to end, no shortcuts for experience. Lights will raise the temperature and you will not want to have any higher temp than 80ΒΊ. So take that into consideration while you're hiding your grow op. As your on a budget I'd look into using a couple of 23 watt or 42 watt cool white for the time being. Later on when they flower you'll want to change the lamp color to warm white.
