diy cabinet question

i made this out of 1x2 in a couple minutes. i was going to use the 3/16 thick board from home depot for the walls. not sure though. and also was wondering if it would be better to have 2 doors in the front, or just one. any suggestions would help. btw, its just for vegging.

I would have two doors
What are the dimensions and what type of lighting are you going to be using?

If you haven't already picked out your lighting, I'd do that first and then build the cab to fit. One of the problems I have with my current veg cabs is that lights are hard to fit inside. They were some cheap cabs from home depot that are 24" wide. What that means is that they are only 22.5" wide inside which is about an inch to short to handle a standard T5 fixture.
