If you have to ask if its enough then quite probably it isn't.
Best possible scenario you'll yield 1g of smokable weed for every watt of HPS light you put into your grow. Sorry to say CFL's aren't a substitute for HPS.
Looks to me you could ventilate a lot more. Get an exhaust fan as soon as you can, and when you start flowering, you'll need a carbon filter. If I were you I'd cash in your first crop and buy a proper grow tent with real, useful lights, and start all over with that.
