-are they alright to use for flowering in this configuration
aprox. 3500lumens/sq foot (see picture for details)
-and will the yield be good with dense buds or some dirt weed?
thankss

Please read the sticky's they have a lot of information about these kinds of questions.
here is a direct link to the one you should read first http://boards.cannabis.com/indoor-li...uch-light.html

As for the other questions:
3 florescent is OK for veg
For flowering it wont be enough for sure, you will have to add more lights and change all the bulbs to warm bulbs(the ones that give out yellow light and not blue) because these are good for flowering.
