Home lamp style CFLs will work, but if it is all possible, set a few bucks aside each week or month. In no time you will have a few extra bucks to purchace a CFL Grow light. They have a nice 42watt/150watt, 6500k & 2700k, CFL grow light for $20 bucks or so. A few years back I was in the same situation and kept 3 plants going for a few months on incandescent grow bulbs. At that point because the lact of knowledge on indoor growing, it did not turn out well. But about a year ago, after the state I live in voted down the legalization for medical marijuana, I started to put a buck here and there away, then March of this year I researched my ass off and set my growroom up, using CFLs.
