Something else to consider, an "air purifier". I have three, but one is for use during harvest, or if I have stinky plants and I have tent open while working. It helps quite a bit. Cuts down the amount of fresh, thick green harvest smell.
I cut and harvest in same closet as tent with it open also, I have another 2x2 tent adjacent connected with a 4" hose into main tent when drying to get sucked through filter.
