I reckon you'd probably be better with two panels in a tent that size, you'd get the benefit of the beam crossover and easily cover the whole tent.
If it's 4 ' tall you will be really tight for space if you try to grow 4 plants.
Mine is 2.5' x 2.5' x 5' (l/w/h), even now at the halfway point in this grow there is no room for another plant beside it and the height problem I could only solve by buying two panels and angling them. My first grow I had two plants competing for floorspace and height even though I was scrogging.
