my growbox size ?

Hello people.

Im looking at starting my first grow,so far i have a light 400w hps and a intake fan, not built my grow room yet,i have a closet but i also have a preaty mutch ready to go box,only trouble with the box is that its only 4ft2 in height but would mutch rather use it,i would like to grow skunk#1 as my first grow,would this be to tall for my 4ft2 grow box

also could i just scrogg, do i just sacure the scrogg over the plants at any time, is it as easy as that

well u could do some low stress training to keep it a short and bushy plant

4ft 2in is plenty of height dude, i veged and flowered in a 3 foot high box that i built and the plants were just touching the top of the box, good luck homie
