6X23W CFLs give off less light than a single 125W CFL and are far more enoying to cool.For your space you should aim for around 125w CFL light or 75W HID.The 23W, splitters and all the accessories will probably cost more than a 125W.Remember that your would need to change bulbs from veg to flowering. for veg you want 6300-6700K (daylight, blue) and for flowering 2300K (warm white, red).The problem with CFLs is that they need to be close to the plant. With 23W you need to keep them 1" from the plants. With 125W a 2.5" is good enough.They main key is to use your lights properly, no matter what they are. Use good reflective materials and shield up everything.For my CFL veg. closet I use a glass tube (something like a cool tube) that my exhaust vent (around 70cfm) is pulling air from and so pulling out the heat from that single 45W.Its not that great, but I need to keep growth slow as I need to wait each time for the flowering room to clear and my veg. space is small.I just let the plants grow on the glass tube. that way they are at the right distance from the light. pretty simple.
