hi everyone, i just started flowering and was wondering would 7,200 lumens be enough? they are all cfl's if that makes a difference.
Lumens?

just understand that 7200 lumens can't penetrate very far. so, you will not have much QUANTITY, depending on, well, many factors. many. quality is as quality does......or some junk.

ignore jimmy... he isnt even a tad expierenced enough to answer you..
how many plants will you be flowering with these cfl's?
you can get one decent small female will this amoutn of lumens if placed properly... not good or great, but decent.
if you can, get some more 42 watt soft white cfl's, these will do great, place them 1 inch away from the plant.

THE TRUTH ABOUT WATT RATINGS
When purchasing a compact fluorescent, you will notice that nearly all of them have a larger number on the box, than what it actually is. This number is the lights comparison to the brightness of a standard incandescent globe. Do not be fooled, this does not mean that the light is 100w! It is most likely around 18w.
Now, here is where the myth behind these lights is uncovered. Most people will say that you should totally discard the brightness rating. This is wrong! The brighter a light is, the more penetration it has. With a usual, run-of-the-mill compact fluorescent (say, 15w) it emits only 15w of light with poor penetration. An energy saving compact fluorescent with 15w of light, which is rated to 100w of light, will only emit 15w of light. The difference between the two is, the energy saving light has a much stronger light penetration of the normal one, while still only emitting 15w of light.
This is beneficial to growers because with a larger plant, a normal 15w compact fluoro will sufficiently light one part of the plant, and by the time the light has reached the other side of the plant, so much of the light has been lost that it is barely worth having. With the energy saving compact fluorescents, the light will travel to the other side of the plant, and still have enough intensity for reasonable results.
HANGING YOUR LIGHTS OVER YOUR PLANTS
Keep these lights under a reflector all of the time to concentrate the light onto the plant. Hang them horizontally, as most of the light is given off by the middle of the tubes. Keep them close to the plants. As a general rule of thumb, 1 inch away from the top of the plant is perfect. Any more, and you're wasting your time, and less and you risk burning your plant (although these lights are very cool, it is possible to burn your plant if it touches the light or ballast for an extended period of time). If you're given the option, go for a few compact fluoro’s positioned around the plant, as opposed to 1 strong light at the top. Positioning lights around the plant help stop vertical stretching, and encourage the plant to bush out.
WHY IS A HID "BETTER" THAN A COMPACT FLUORESCENT?
HID lighting is generally accepted as a better light for growing cannabis for a few reasons...
· It has much better light penetration
· It is much more powerful (higher lumen output)
· It is stronger in light spectrums suited for growing plants
What can we do to combat these problems to make the most out of our fluoro’s?
· Use a good reflector. Desk lamp reflectors are perfect, along with coke cans (cut in half from top to bottom).
· Purchase lights with high energy saving capabilities (e.g. high watt ratings)to increase light penetration
· Purchase lights with suitable spectrum strengths for each phase of growing (eg warm white, cool white etc.)
· Keep the lights close to maximize intensity
