2 tents 1 fan…

Jesus fucking christ, thats a long fellow. I've only seen one larger than this and it was in a room with a little over a hundred Master Kush plants in a perpetual flower.
Lol.. I tend to go way bigger than needed when it comes to ventilation/smell control. I paired this up with an 8 inch in-line fan for about a 4x4 space ‍.. Way overkill…. I’ve since traded fans with a buddy for the 6 inch because the 8 wouldn’t even run on the lowest speed without shutting off before it felt like it was going to suck my tent through and blow it out of the fan

Ever consider using a intake fan to help keep the pressure reasonable with the 8in fan? Obviously its a little late now, but I'm curious if you saw some negatives that I'm missing.

no, honestly this is my first time using a tent and also first time using LED. I’ve been having lower temp issues and trying to keep them up is harder than trying to keep them down with MH/HPS so far from what I see.
So I turned the 8” fan down as low as it could possibly go and i must’ve had it teetering to the point of powering off, because it had shut itself off. It was Within the first few days of setting things up so I was constantly popping in to check temps and whatnot. The temp increased about 10 degrees in there (about 85) before I noticed it

Carbon becomes ineffective if moist; outside in winter seems problematic.

The ass-to-mouth configuration can work but may need some tinkering with venting to get it tweaked.

issue with putting the scrubber inside the tent is it weighs a TON.. I’m afraid my tent won’t l be able to support it plus the light and fan…
You should try it. Most tents are more than capable of supporting this equipment. Just make sure you distribute the load somewhat (maybe among two cross-beams or the like).

You can also hang one large sheet of (thin) plywood from the ceiling of the tent, distributing the weight, and then hang the equipment from the plywood. If you put several hooks into the plywood it gives you a lot of flexibility without having to move beams or belts.

If that becomes a problem, you can always have the scrubber outside of both tents (in a "push" configuration), but you should not put it outside into the cold air. That really seems to be the worst possible configuration (due to condensation, and also because it's conspicuous and because you would need additional shielding for the filter).

Probably gonna need to run your breath room cooler and dryer I don’t see split exhaust working to efficiently unless you’re using a bigger fan or smaller tents probably work ok with an 8in split and reduced to 6”

why not just pick up a cheap 4in fan for the 2x4 and call it a day

I’ve decided this is the route I’ll go.. just going grab a 4” in-line to vent the 2x4 into the room where the tents are and then have the 5x3 with the 6 inch pulling outside. I weighed my scrubber last night and it’s only 43 lbs so I’m going to try to support it across 3-4 spots inside the tent and pull through instead of pushing out to avoid having the scrubber sit outside.. I really thought it was heavier than that!

I like the plywood idea.. just don’t want to add any more weight than I have to. Between light, fan and scrubber in probably at around 70-75 lbs..

as far as the scrubber outside goes, I’ve scrapped that idea For putting it outside and will go another route. Thanks for the input
 
Hi everyone.. like the title says, I’m trying to see if I can run (1) fan to exhaust (2), small-ish tents.
Tent 1 is 32x60x80 (almost 5x3) and the other is 24x48x60. Based on my beautiful sketch, does this seem like it would work?

Here’s some details;

5x3 has a Viparspectra 480w LED fixture.
2x4 has (2) 120w LED fixtures

The fan is a Terrabloom ECMF-150, 6” in-line rated at 288cfm. I know, on paper 288cfm doesn’t seem like enough, but it’s currently only running on just the 5x3 tent at about 20-25% speed (into a scrubber) with the 480w light on 50% and it keeps temps below 77f, so it seems like there is plenty of wiggle room for more air movement.

I just have to get a large tote and some blocks for the scrubber. The plan is to mount it outside, just raise off the ground and covered. Is this ok during winter months??

Any other ideas? Would a“y” fitting work better than a tee or would that not even matter?View attachment 5054314
The exhaust fan should be in the middle of the 2 tents so it doesn’t take more air from 1 or the other

Most tents are good up to like 150lbs, more on the bigger ones

If you’re just after odor control set the filter up in a corner of the tents room somewhere maybe on an end table put the fan on it and have it pull air. No duct work to mess with, just plug it in.

Believe it or not, you are not the first one to hang 30 kg from your tent roof. Even the "cheap" tents are more than capable of holding such a load.

Here is yet another option: put the carbon filter with an attached fan on the floor, in a corner of the tent. Then have it permanently recycle the air inside the tent, eliminating most odors. Use another fan (with no filter) to exhaust the air from both tents.

I tried to do this & was too much of a headache. I just went with another 6" affinity for my 2x4 & run it at lower speed, love these things.
