Starting my first DWC, suggestions?

Hello everyone, Im about to embark on my first DWC BB grow. I believe im going to be growing some Vanilla kush in a 5 gallon bucket, with an 8" airstone disc. Its going to be under a 125watt 6500k CFL for veg and 2500k for flowering, possibly two cfls. Im planning on using AN sensi grow, and sensi bloom along with bud candy nutrients. This will all be done in a GL80 grow tent.
Would it be worth going with this light over a CFL?? http://www.growwurks.com/sun-blaze-4-2-lamp-t5-fluorescent-light-fixture.aspx

Any suggestions or concerns??
Thank you!

If your growing one plant,I would use 3 cfls in each stage.That way you can use them right where you need em

Ok thank you, that makes sense, the nutrients are ok?
T5 lighting isnt worth it? I will probably LSTing, or SCROG the plant
