hey all,started the framing of a veg/flower cab and trying to figure out how to block the light from the veg section to the flower.the veg area is down bottom with the flower on top.my exhaust fan will be in the flower cab part with the incoming air/fan in the lower veg area.i need to get a hole in the floor of the flower area(which would be the ceiling of the veg cab) to allow air to get from the veg to flower.how do i block the light?any ideas?
