Grow tent vents

Hi guys basically i have a 2ftx2ftx5ft tent with a 600w led grow light, 5" fan 355m3/hr, 4" carbon filter.
Basically at the bottom on my tent i have 3 vent flaps at the bottom about half a ft off the floor and i get alot of light coming out when there open, do i need these open all the time? If so, how can i reduce the light issue as want it stealthy so less light the better as it goes into my bedroom

4x4x5 is the better choice

or put in an air extract system

vents at the bottom are best left passive

good luck

Is there any way i can reduce the light?
