3 Tents in 1 room..how to .exhaust

[Ben-Do]

so I've got one 4 x 8 with a cloud line fan but I have two other four by fours and I have no fans for them or any idea of how to tie all three in together to be able to exit the air out of the room. Any ideas? Could I get one more fan of that caliber and use it for both remaining tents? My fan was about $150. i've also got one exhaust ceiling fan from Lowe's that was $45. It doesn't have but maybe 350 CFM.

What size is the fan you have inch wise? How many cfm can it move? How many cu. ft. do you have total between the 3 spaces? If you think the single fan can handle all 3 spaces (not likely, but possible) then all you need is some ducting and some y elbows that they sell at any home improvement store or hardware store. It splits one duct into 2. One duct for each 4x4, then you'd have to split again before the fan. If you plan on running any carbon filters, you're really going to need multiple fans. Between loss from the filter and distance of the ducting, you really should run more than one fan.

So how tall are the tents so i can get an idea of how many cuft need to be moved, also are there windows? You may need to take that exhaust clint fan out and directly hook all your tents to that vent port and vent them all out of that for best results. That sounds like an HVAC professional might be good to consult so you don't accidentally start a fire by having too little or, on the other hand, too much ventilation. As @MI_sterGreen stated above it can be a huge issue doing it all and that's why I suggested an HVAC professional. When I designed my new grow area, even though it was less than 300 sq ft i consulted professionals to make sure it would be an adequate space because a huge issue one can end up expecting is *mould, mildew and other fungal spores* in places you don't expect it. Especially in ducting.

Also, if you think you're going to get another ac infinity product, let me know. I have a 15% off code.

hey, thanks!
to answer above,i've got two tents at 4'x4'x7' and one is 4'x8'x7'
i think that is 448 cu ft.
i've got the cloud line 6". it has the sensor and monitor screen and can operate two fans.
i've got an a/c 12,000 btu now adapted into 6" ducting blowing into the low circular openings in the 4x8 and one 4x4 tent. it's exhaust going straight up into attic.
treat it as if no other exhaust fans exist except one booster exhaust fan in the fan exhaust line going out into attic (Yes--the ducting is run all the way to top of roof near ridge vents) .........
i've got another 14,000 btu A/c unit on deck
i thought maybe just cool and dry the ' room air' with a/cand dehumidifier and just pull air into the three tents via the exhaust fans. i have all LED { ( only standard quad-boards and strip lights,SamLm301h w/660nm with one ES 300v2.... 550w, 600w, and the big tent has 1400w LED) ....whew! dammit boy, i'm stacked on lights! } all creating the heat in the tents.

LMK what you think bro....
i got some sweet looking ice cream, cake, candy, and cookies all in flower now.

i hope i answered above

I only have 2 tents. But I have a fan and carbon filter for each. After the air exits the tents it joins at a "Y" and continues outside through one duct. Eventually there will probably be a third tent and I will probably just add another "Y" and splice it in to the duct heading outside.

A good rule of thumb is being able to completely exchange the air in your tent once or more every couple minutes. Some say more frequent than that, especially of there's excessive heat and a large plant count. One 4x4x7 tent is 112 cu ft. So you'll want a fan that can completely replace that amount of air several times over a few minutes. So the rating of the 6 inch ac infinity fan is roughly 315 cfm. Thats at maximum speed. Subtract 20% if you're running a carbon filter. If the ducting is any sort of long (more than 8 to 10 ft) you'll lose even more. With all those factors considered, you would have to run that fan 24/7 at maximum speed just to have regular fresh air in just one of your 4x4 tents. IMO I would run each tent with its own fan and then join the exhaust from all 3 into one very large duct. The reason for that, is so each tent can have its environment controlled separately. If you're running multiple tents in separate stages, different humidity levels are required. Having multiple fans makes that much easier. Sorry about the long-winded response. Id say one more 6 inch ac infinity and either an 8 or 10 inch model ac infinity fan for the 4x8.
