how to exhaust 2 grow tents with same fan

[pppp1500]

I have 2 small 2x2x5 grow tents which I want to ventilate properly with only one 400cfm 6in inline fan.

One tent is for vegging (no odor) the other is for bloom (needs scrubbing).

Both have 150w HPS or MH lights and need to pull heat out (outside the room, by the window).

I could use a wye split on my ducting but i suspect that the carbon filter will cause much more air to be pulled from the veg side than from the bloom one beause of the restriction from the filter.

Any idea what would be best ?

Put dampers in the Y. Choke down the veg air till they equal out. Good luck.

Have passive intake on veg, passive intake from veg to bloom, exhaust from bloom tent. Double sq inches for intake than exhaust. Good luck. -granger

I have a 4x4 tent and a veg/dry area all being exhausted by one 8" Vortex in the attic.

What I did was, I use a 8x6x6 wye on intake before fan. 8" goes to fan intake, one of the 6" goes to tent ac reflector. On the other 6", I have a 4x6 reducer. So then I have the 4" go to the veg/dry area. On the exhaust side of fan, I have the fan actually blowing into a carbon scrubber. The fan is 747cfm, and the scrubber is oversized since I'm blowing into it, instead of sucking thru it. Scrubber is rated for 1400cfm.

Been running it like that for years. I know it's not the way the scrubber is designed, but haven't had any smell. Also, haven't had to replace scrubber yet and it's gotta been running for 5+ years now. I do a perpetual grow, and only two plants at most are flowering hard. Even with my dry area full....no smell.

Just for record, dry area is on top of veg area.....air sucks in thru bottom of veg area, then gets sucked into dry area at ceiling of veg area, and then off to wye.

Hope this helps.
