Your losing
half your light to the ceiling by removing your hoods in a horizontal setup===== less yield. Seems brighter due to more light bouncing off the orca, but inverse square law comes into affect. A good reflector has less than 5% light loss, would be gaining around 40-45% more light to your canopy. For your large area , I would look at the raptor option.

I would think HARD about adding reflectors again or run bare vert/stadium style.............not trying to be a dick, just want the best for your garden
