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 three hoods and then into the attic. I will also have another fan to exchange the air in the room with a scrubber again venting into the attic.

Questions
1. What size fan for the hoods?
2. What size fan for exchanging the room air?
3. Or can I run filter>hood>hood>hood>fan>exhaust to attic? (Filter in grow to also exchange air,so only one fan.)
4. I am guessing I will need to run 220 into the room also? It will be tough to run wires because its upstairs and in a finished home?
5. Thoughts on wiring? I have Lumatec Digital Ballasts.
Thanx

That size room and that many lights you don't want to a filter on your lights. Sucking restricted 80 degree air from your room thru your hoods won't cool them. So your first idea is best. Asfor wiring. If you don't know what your doing get a electrician.

6 inch hoods 8" fan min. Check out the link in my sig. Think it's page 2. Vid of my lights. Best way I found to cool all.

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 run 1 6" duct from out of the room. Then ran it to the fattest hood. Then used T's to go to the others. This way no light is getting the heat from the other. Then did the same on the other side going to my 8" fan. When I had them in a line the last 1000 was hotter then if I just didn't vent it. Hope that makes any sence.

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?

1fan at the end pulling. They pull even because on the other side of the wall I have a AC grill over the 6" Intake hole. And a house filter. The paper one you put in you heater/AC vent. This restricts the air enough that it's alway under negative flow thru all hoods. If I had it just open you would be right. But restriction is key. Not to much but some is needed.
