Need advice on grow.

I have a space that is 2 x 2 x 4. I was thinking of using these CFL.

Is that enough space? If not I could push it to 2 x 3 x 5, but I would rather not.

How many plants would fit in there? I would be starting for clones.

How many lights would I have to use to get decent results?

Thanks

how much are you looking to yield? i woulld say two of tose would fit perfectly in a space thats 2x2x4

That will work for veg 6500k. You will need something around 2700k for flower. or try craigslist for a real light. A 250 hps would rock a grow area 2x2 or 2x3 and still be able to cool it. They should go for around $100, look for a switchable ballast. Those big cfls get pretty hot. You will have to vent your box either way.
