V = VentilatorA little hard to understand, no measurements and no access points marked out. Whats the dimensions and where do you access from?
I prefer one big fan, the smaller ones suck.How much vertical space? Id generally rec oscillating fan above cannopy, two smaller ones one in each end. Maybe even clippon hanging from the lights. And something moving air below: ideally oscillating fans or just a bunch of smaller fans pointing at pots or just wall, giving you some "diffuse" airmovement. Being low its always colder and damper, were you'll have most likeliness in mold starting.
