How tall is your flower room? She will likely stretch once you get her in there. If you can slowly cut-back the foliage directly under the light, making the top of the plant a cone-shaped hollow, (allowing light to interior of plant) might delay the need to change, till you make up your mind which way to go.
Good time to learn. When you are cutting her back, if that's what you do, try cloning without hormones. Costs nothing but a little bit of your time, and the price of soil.
I'd consider a 250w MH, along with the t-5's to suppliment. You just don't get the same 'kick' with fluorescents, in which light would effectively penetrate only a few inches from lamps. Interior and lower 3/4 of plant would get virtually no light.
