That is exactly the worry with little head-room.
Under 4 feet you are REALLY limited:
-hydro is out since the equipment itself stands minimum 18" off the floor, unless you do a res OUTSIDE the room and have an active return to the res rather than depending upon gravity
-large plants are out because of not only their stature, but the root ball needed to maintain them.
You say you are doing a SCROG- many small plants or few large ones? Root ball/pot size again.
You have some options:
-Buy rooted cuttings from a reputable source and just run SOG under a hps600 (pushing it for that space but it depends how bad ya want it)
-Find a second grow area where you can maintain a soil mother under 24 hours of light and take cuttings off her
-Consider a t5 flourescent grow using a pair of 4' x 12" fixtures mounted right up against the roof of the space, or even 3 or them, or a whole mess of shop lights with t8 'daylight' bulbs- my buddy used to veg under a canopy of I think a half dozen shop lights mounted on rails- it was indeed bright, lol!
-build a freestanding grow tent with more head space?
