That is a lot of lumens for such a tight spot, you will have to be careful of light burn, a 4×4 tent is supposed to be ideal for a 600w led even though the light is not pushing 600 true watts, it's the amount of lumens the light is throwing, for sprouts i back my 600w light to 35inc, once there seedlings i drop the light to 25inc above canopy, in flower i have a bloom booster i leave it 14inc above canopy, as stated your throwing allot of lumens so your gonna have to play around a bit, remember you want your seedlings reaching up to the light not shying away from it or bleaching out or burning, good luck.
