perlite and super thive from walmart. if your getting hps then try to wait to start then. i would do hps for both veg/flower before cfls for veg and hps for flower, but cfls for first week. with hps you will need to think about venting the grow room. "heat" i did the same light thing your doing in the begining. got to walmart in the lights there is a that light fixture that replaces the fixture on bottom of your ceilingfans that holds 4 light bulbs in the same amount of space that yours do. two of those would be 8 cfls in the same space you have two. but this will that some basic wiring on your part. just get exten. cord and elc. tape. and mount on piece of wood and hang works great for cfls. ill try to find some of my old pics.
