I can't afford nothing expensive. Where do I buy the lights from?
I will make a write-up on some cheap lights tonight for you, so that you have a reference with some in-depth info.
For now and to make it quick...
Go to Home Depot, you know they will have the adapters you need.
You need a 4-pack of 23w or 26w (whichever they have) 6400k (blue "cool" bulbs) CFLs from Home Depot. You can get a 4-pack between $10-$12.
You need One cheap $2 extension chord that has two plugs on it, one on each side.
You need Two Y-Adapters for your light sockets. They will be on the same isle as the extension chord.
You need Two Socket-To-Plug adapters for your lights to plug into your extension chord. They will be with the other adapter.
Plug the adapters into the chord, and screw the Y-Adapters into the socket adapter. You now have 4 CFLs attached to your single chord.
Hang that baby about 4" over your plant. Good to go until flower.
About $15 altogether for 100w of blue CFL lighting.
This is what they will come out looking like.
That 100w will serve you until flower, or you can even flower a small plant with it. If you flowered with 100w of CFL and your grow went perfect, you could probably pull close to an oz off one plant if you bush it up correctly.
