Does anyone exhaust into the same room they are growing in.

Thank goodness the plants were dealing with are so strong. I'm sure that I personally would kill them just about every time I tried if they were any weaker. go go go go go go

I'm sure of that too, and luckily I didn't kill them, on the contrary they were healthy, well some of them were kind of dwarf plant lol.
I got no deficiencies, the run was a real pleasure to grow.
But... as I explained I'm quite sure that the extreme heat all along resulted in the volatile stuff to evaporate - even more so during drying.

I may be wrong, but I can't explain otherwise why the potency is so low... if anyone has a different theory ?

Hello folks,
has anyone tried to exhaust the stale air in to the same room the grow tent is in.
If so, what were the results? Speed Test
I tried it last grow and although I had decent yields, the potency was very poor.
Anyone had better results.
In my grow room I do not have a window.
The grow room is in the upper area of the house. There is a window in the next room about 7 metres away.
If I left this window open I would have access to fresh air, but I would be at the mercy of the elements and pests and mould.
I like in the north of the uk so humidity is high.

Would I be ok just to keep the window closed but keep the door leading to the upper part of the house open to allow fresh are to find it's way up there?
I am in and out of the house 10-15 times a day, so fresh air will be coming into the house when I open the door.

Thanks for reading and look forward to you're replies, as I would like to get something sorted, or I'll won't be able to grow anymore, as it is just not worth it.

I can’t think of a reason why it would effect your quality, it must be something else.

Don't you think the lack of fresh air will affect quality?

At one point, I exhausted into tent room for many years, but I always prefer a window cracked for fresh air. If you have stale air, get an air purifier.

I know this thread started a few months ago but I've been seeing it bumped recently so I'll throw my bit in as well. My tents are in the basement, tucked away quite well. The whole space is pretty large and I run a big dehumidifier year round. It's currently 99% humidity outside and everything is dripping wet. Inside? 50% in the living space and I keep the basement set to 40-45%.

My intakes are on one side of the tents and the exhausts are a few feet away out the other side. Same room/space but the flows are directed away from each other so the intake doesn't suck in wet air immediately. Perhaps running a duct towards the doorway to allow it to pull more "new" air could help?

You could also try a small circulating fan outside the tent, maybe on a timer for a few hours a day? Just to mix things up a little. That definitely helps my dehumidifier cycle air better.

Good luck!

Thanks everyone for the comments.
Judging by the comments so far there should be no problems.

Thanks again

Why the concern about stale inside air? What toxic agents or adverse effects are there for the plants? [I can't think of any].

For plants our stale air, such as with well-sealed homes in the winter, is likely better for growth than fresh outside air; with higher CO2, humidity levels and no temperature shock if piped directly into the tent in the winter.

And keep in mind, in the winter exhausting tent air into your home adds heat that would otherwise simply be exhausted while an equal amount of cold outside air is collectively drawn into the house.

So I just keep it totally simple - have the tent with no external intake or exhaust, and run a room window AC (or open the windows) as needed in warmer months (best to have very high efficiency lights if running tent in AC cooled room).

Isn't it a problem to be recirculating the same air over and over?

I exhaust into the same space. Its a large basement though. My exhaust fan even pushes air out to the same side as my passive intake is on.

But it should be fine unless its already in a confined space without any fresh air exchange like ever. You can always use a fan in the lung room to move air around better and help exchange air from the rest of the house faster. Ive been doing that to help move the heat around the basement. Otherwise it all stays in the back and my tent starts roasting after a while. But thats only in the winter.

Yes but thats if the room is sealed. I doubt your room is basically air tight. I saw you ssid its in a room with no windows. Maybe I missed it but how big is your room, and how big is the tent?
