Hey Camox, if I may interject here. I've only heard of intake fans being necessary if you have a large room with a lot of lights and heat. In your setup it might be more efficient to just have a passive intake (no fan, just a hole, or you can make more than one, depending on how much exhaust you have) and have multiple active exhausts (active meaning it has a fan). Also you should have a slight direct breeze on your plants to help strengthen their stems and move the air around... Best for this is an oscillating fan, but I'm guessing that table fan you have is doing that already. Hope that clears things up a little :jointsmile:
