Electronic ballast sonlight 250w hps/mh hydroponics slp

Hey Guys

So it all started with some bag seeds, now they're germinated and currently under a 25w cfl that I had lying around, and I know 25w will not do the job so i whent of and researched all the different type of light, cfl, led, and hps. Now at first i really liked LED but did not like the results that people where getting, then whent to a 250w CFL and ALMOST got it.. then just today, stumbled across a HPS for a nice price.

250w CFL - will produce about 18,000 lumen's and has a choice for Veg(Blue 6400k) and Flowr (Red 2700k so total cost would be around 40e (red and blue)
250w Ballast - will produce about 27,000 lumen's and its recommended MH for Vegetation and HPS for Flowering so the total cost would be around 100e.

Its 60e more then CFL and i will be growing 1-3 plants (2 most likely) do you think I should go for the HPS? Do you really think I will benefit that much over the CLF? Like will it increase my yield a good bit ( pics ) ?

+rep for the guy whit the least mount of fanboyi'zim ( u know what i mean)

Thank you
