Vero build, and questions about reflectors

I'm putting together a Vero build to replace my HIDs in my flower room.
I was thinking about swapping my 2x600w HPS with 3 of the Rapid led canopy rails each running 4 Vero 29s on an HLG-320H-C2100A, which should be ~75 watts per cob if I understand all this correctly.
I plan to flower in ~4x6 area in an 8x10 room. I'm not really sure what to do reflector wise. Can I just leave them bare? I only have 6'5" of height in my room if that makes a difference.

If you're not in a reflective area it's better to use reflectors. You could always put up a partition that you can move whenever you are working with the plants.

right on, any thoughts on which reflectors would be best for my setup?
RapidLED has a wide, an extra wide, a round, and something called a stella.

The room is panda filmed, so I could have a reflective wall on 3 sides pretty easy, and a drop on the fourth side that I could roll up might work, though I worry about it wearing out with me going in every night

My opinion, you're better off with reflectors than lenses and I would go with the wide rather than extra wide.

If you are relying on walls and partitions you want them to be right up on the plants during flowering (or right up to whatever their max size will be). You can buy reflective insulation board at the hardware store for cheap and cut it to size.

If you have 3 reflective walls you can just put reflectors on the cobs bordering the open side and leave the other ones bare. just a thought...

Thanks for the input guys
