A 2x4 tent is good for veg. But i use t5 bulbs instead of CFL. The cfl bulbs dont really put out a lot of light. I had 3, 100 watt Agrobrite bulbs in my 2x4 tent, I'm glad i switched and went with 8 25 watt t5 bulbs at 2 foot long. Better light penetration through the canopy that way. Also, in my travels around the inter web i found more suppliers of quality t5 bulbs over CFL with a built in ballist. But if going with a CFL is what you want i would look into the 250 watt bulbs put out by Agrobrite. They have them in both 2700k and 6500k.

This is one of the least expensive "decent" light for you from a manufacturer that;s been around for a while. https://www.mars-hydro.com/hpcall/new-arrivel-hp/buy-mars-sp-200-led-grow-lights-for-for-sale. If/when you have the money there are some better, higher quality lights out there, but you may want to upgrade your grow space before exploring them.

You may be able to deliver enough light using cfl's to veg a plant but it won't flower very well.
Using power metrics is a useful tool to estimate 'how much'.
Current tech leds-30 watts/sq ft
HID(CMH, HPS) and 'blurple' leds-50 watts/ sq ft
CFL- 60-70 watts(actual)/ sq ft.

If hard set on FLOURO lamps , they do grow plants pretty well for what they are. I still use an 8 T5 lamp rig with mixed bulbs for tray starts / clones and rooters . So there are T5 rigs out there.
But if you are looking at serious growing .... CMH , HPS , LED ( bars / strips / boards ) , COBS
You will be doing a disservice to your plants if you skimp out on lighting. I used to do cfl for single early plant starts but you will do much better with appropiate lighting.
