Hello! I'm using a 5x3x6ft grow space and was going to install 1 600watt HPS and 1 1,000watt HPS. I'm looking at vivosun's ventilation kits and was wondering if I need a fan to go between the two lights if I already have 2 on each end, or just need a vent tube. I'm imagining a setup where I'd have one fan blowing onto the bulbs from the left, a tube connecting them, then 1 fan blowing the other direction into an exhaust. My question is how many fans do I need to pull this off? Will 2 be good enough at cycling the air, or should I grab a 3rd to go between the lights? Thanks in advance-
