Indoor Anybody ever vent 2 tents with single fan?

[fweedom]

Is it possible to use a single exhaust fan to sufficiently pull air from two seperate tents?

Ill try to explain without a picture...say i have 2 grow tents each with a 400w air cooled hood in it.

Lets say they are 2 feet apart with a single exhaust fan in between them. if i attach a Y splitter to the exhaust then run duct into each air cooled hood can i use that single fan to pull air from both hoods/tents?

anyone ever done anything similar or seen it done another way? :smokebuds:

i plan on ordering another tent and light but if i can save some money from using the exhaust fan i have now to pull air from both id like to do that, if theres no way possible ill get one but i thought id see what you guys think

The more ventilation ducting you have, the more lights you have to cool, the more CFM you need.. also with 2x 400W HPS, make sure you have a way to exhaust all that heat and it's not recycling into the same room the tent is pulling from brother. Otherwise the air-cooling becomes pointless.

So yes, you can use a single fan, but you'll need one of great quality, like a Vortex.. Even then there's no way for us to really tell how well it'll perform until you do a dry run on it, but for the price of the Vortex you can probably get two single fans you know will work.

Agree with goodie! Calculate your cubic ft for both and do the math to how many cfm's u need and then find a fan that will handle both tents! Factor in carbon scrubbers, duct work length and temps! Trial and error bro! It's a bitch! Lol

The link for the Vortex in my post isn't the cheapest but it was just to give you an idea of what you'd need.. and be warned, they're not quiet.. I have one in my closet, can hear it down the hallway if it's on full speed.. that's with the closet door closed, room door closed.. haha.

would this work..http://www.amazon.com/Hydrofarm-Active-Air-inch-In-Line/dp/B002JQ14F8/ref=pd_sim_hg_2

to pull air from two 36'' x 36'' x78'' tents?
heres the link to the tents..http://www.amazon.com/LEDwholesalers-GYO1005A-78-Inch-Reflective-Hydroponic/dp/B002TZTS8E/ref=sr_1_16?ie=UTF8&qid=1360640612&sr=8-16&keywords=grow+tent

Id have a 400w air cooled hood in each one..:smokebuds:

Yea Man. I got two tents a small 2x4x4h and a 4x4x7h, the lil one has a four inch filter in the tent and a 6 inch filter pulling outside. The big tent has a 6 inch filter in the tent and a 6 inch fan out, pulling. T5 in the little tent 600w hid in the big. After the fans comes a wye to a filter and out. I also have an inline booster on the hid. So to answer your question, and I had to over vent just in case. I can run the big tent with the little tent fan off and the draw is enough to cool the little tent. But I am glad I got extra power it's winter here when summer comes i'll need it.




I had to over build to find this out but all good in the long run.

Invest in a duct muffler, I've had fishtanks louder than my grow room since adding, and I am running two fans thru it:thumbs:

did u mean a 6 inch fan pulling out cause i only see 2 filters and two fans?

 

[fweedom]

so if i had one tent that was 3' x 3' x 6.5' which is 58.5 cubic feet i would need a fan that can pull 3 times that so 175.5 cfm?

my other tent would be 2.5' x 2.5' x 5' which 31.25 cubic feet so times 3 would be a fan that can do 94 cfm.

175.5+ 94= 269 i would need an exhaust that can pull atleast that correct?

If i wanted to put a "y" spliter on this single exhaust fan and run duct into each cool tube in each tent ( id leave one side open of each cool tube for the air to be pulled through) this 400CFM fan should work?

i would have intake fans in both.
