Exhaust system for 4X4 tent

I’m not quite understand what you’re saying. Are you growing in a tent, or just open growing with a portable A/C in the grow room?

I have a small room, yes there is no tent in the AC is in the room

Ahh… ok, gotcha. I wonder why the sound is so loud outside your house? The sound from a tent exhaust fan shouldn’t be as loud as a portable A/C, I would think. So maybe I would be ok.

My biggest problem is that I would have to do this myself, as I couldn’t risk hiring someone else to do it. I’m 80 years old, and a woman, although I’m very fit for being this age, it would be difficult for me. I wonder if there would be any YouTube videos on doing such? I’ll have to check it out.

I would start with the exhaust going to the “lung room” and see how it works out for you. If there is a problem, it will start small so you will have time to implement a new solution.

Oh, thank you for that, merlin44. I feel better about it now. I will just exhaust it into the room and see how that goes.

The primary reasons for the exhaust system is to provide fresh air and to control tent temperature. As long as the lung room temperature is cool enough, you should not have much of a problem.

You only have about 10 years on us, so we understand the challenges of climbing into the attic and whatnot.

I can definitely control the temp in the lung room, so that wouldn’t be a problem.
I do have another question here. The air in the tent is being exhausted through an exhaust fan, but how does fresh air get into the tent if it is sealed up? I just don’t know these things so patience with my ignorance is appreciated.

I just set my fan in the top vent of the tent, intake side in and filter out. That leaves more overhead room.

You will want to have one or more of the lower ports/openings open for makeup air, with perhaps a “light trap” to keep extraneous light out. I use a 6’ section of flexible ducting to serve as an inlet air. I bend it so that light does not get in.

Ok!! Very good explanation for this question for this dummy. I don’t have the tent set up yet, so I don’t know what it has. I haven’t read the manual that came with it yet, as I won’t be ready to set it up until probably late November. The manual probably mentions those ports. Thank you for that info, merlin44.

There should be at least a couple of ports high on the tent sides and a couple more that are low. I think that some tents have ports on the top as well. Normally these ports have drawstrings for closing them off or sealing around the cords or air ducts that pass through them.

That looks like a good solution to me, SausageMahoney. That’s what I will do and thank you for that!

So I can attach ducting and make sure it’s bent to keep lighting out. So using 2 of them would be adequate?

As mentioned, leave you a vent open, at the bottom and opposite. You will have to pay attention to the humidity as well. You can get a small environment monitor fairly cheap. Generally try and stay between 60-70% RH. It’ll take a little time but you’ll get it figured out and you know we’re all here to help. Hope you’re doing well.

This will likely make more sense when you get the tent setup and get a good look at it.

One duct for exhaust and one for makeup air should do the trick. If you want more makeup air flow, you can either use a second inlet port and duct or go with 8" ducting for the makeup air.

@Lornakinsh if you don’t have something already, something like this may be interesting to you. There are many similar options with various features at various price points for different needs and budgets.

Do you get a notification if it’s a reply to you? Seems like I don’t, so maybe not?
