Well without sufficient light intensity and a sealed dark area you won't be able to flower. The light determines the final product in a lot of ways. You need a minimum spectrum and density to get reasonable buds. The reason I say wait until you have a tent and light is for yield.

Now for price I've found these guys to be solid. And I like the density and quality of the buds I get from them. I don't have a deal with them. But they may be able to provide you an additional discount. They are here on the forum. For limited space their small lights would be suitable.
If that's fully out of the question what kind of light are you working with now?
