Does size matter?

In an indoor grow where heigth is controlled does larger containers always mean better or is there a point where bigger doesnt mean better....Ex....2 plants in a gaint ass pot or seporate them into 2 decent sized pots so they are easier to rotate and control what have u

2 pots cus if you have problems with one it wont be the other, if they were together you could have problem with both

They will end up fighting for nutrients and things as they grow out. And like DO3SHA said, if one has problems you won't be disturbing the other while trying to fix it.

Thanks gentlemen.....safety in numbers.....
