What do you guys think about my micro-grow cab?

I'm going straight into a 12/12 due to the limited space and the genes of the plant. Wouldn't this make it not necessary for a veg light?

It'd still be useful to have your blues (veg lights) in there for a bit, maybe do 1 veg 1 flower light and then after the plant's got a bit bigger stick 2 flower lights in there... just what I'd do cause it seems logical

and the plants still need blue spectrum for growing.

I never use bloom spectrums. I have a T5 with 3000k bulbs start to finish.

I will take this into consideration.. I have heard that when grows lack blue spectrum the plants tend to be lanky and thin. Thanks everyone your posts are all very helpful.
