One big plant or a few small ones?

Hi all,

I am growing in a closet, I have about 2ft(L) x 2ft(w) x 6ft(H).

Im on my second grow and just started to flower. For these first 2 grows I Vegged for 4-5 weeks to get one big plant then flowered.

currently my plant is about 2.5ft high and touches all the sides of the grow box. :)

What I am wondering is if my yeilds would be better if I was to have 4 smaller plants and started to flower at 12-14 inches?

I am growing Afganica(indica Dom), currently under 400w HPS.

thoughts?

With that limited area I think I would stick with 1 plant.

Yes better off sticking to 1 plant and let it fill the entire space instead of multiple plants fighting for that space.
