CFL's are awesum....probably the best way to do an indoor grow up to 45 days. Better than MH if you ask me.

But when it comes flower time....things change.

There are special 2700K CFL's on the market....but....you need to keep them inches from the plant surface and thats almost impossible to when flower time rolls around.

You will get all kinds of buds with CFL in flower....but they wont be the tight, dense had packed buds you might get with an HPS.

You still need to deal with your fan / exhaust issues with CFL as well as any other lighting....

Yes an ounce or two for a plant is fine but it really depends on how much do you want to harvest....if you;re happy with an ounce or two,........then yes you can do it.

If you intend to CFL the whole trip, you will need about 2 of the 125W 6500K bulbs....for veg and 3 125W 2700K bulbs....per plant.
