I have 6 fluorecent grow lights @75w each it gives me 450w. Is that enough for a complete life cycle? will I get some buds or am I laking some more light? The cheapest HPS I have found is a 175w fixture for $130.00 and that is definately out of my budget for lights.
Well it depends on the size of your grow room bare minimum is 35wats a squarefoot but your plants would love 60 on up a squarefoot. I have a grow space of 3 squarefeet and I only have 63wats believe it or not my baby is doing great. Check her out http://forum.grasscity.com/showthread.php?s=&threadid=3573 my precious baby lol.

IMO,,,you may need more light,,depending on growspace,,even a 70w hps from home depot ($45)added to what you have (I suspect you have Compact Flouros)will help gain intensity....The 175w you mentioned ,,unless otherwise labeled,,,is usually Merc Vapor,,you don't want that one,,especially for that outrageous price.
