at my attempt to completely master and control the humidity in my tank, i decided to get a even longer piece of plexi glass to cover my tank, but is this tooooo long? is enough air getting in?

it is exactly 1.5 inches of open space. Is that letting enough air in? should i drill some holes on it, or am i good to go?
