Yes it makes sense. I am just not sure how your flow works? Is there only one fan at the end of all the duct pulling air? Or one fan at the beginning pushing air? If you are pulling air wouldn't the hood closest to the fan draw more air than the hoods farther away from the fan?
I was going to run duct from the wall(cut a hole through the wall out into the hallway.) Then duct into one hood out of the hood then into another hood and so on. I watched your Video but am unsure how you set up the two banks of duct?
I currently have a 600hps and a 1000hps with vented hoods. I will purchase either another 600 or 1000? I will use 3 ebb and flow tables. The room has central air. Outside temps run from 0 in the winter to 100 in the summer. I will run a passive vent from an adjoining hallway and duct through all...
