Sorry, didn't mean to cause panic. I think it all depends on the volume of air you're exhausting. There needs to be an equal volume of coming back into the house from somewhere. Most small grows will be fine using that vent. Use dampers on the dryer vent if needed.You're scaring me now... Why couldn't I just vent a tent through the drier vent that's already in my basement.... What kind of furnace/water heater is this okay with?? The drier vent has been there for years now and its not a problem.
I have 5 tents that are either 3x3 or 4x4. My basement is 700 sq feet... I have my central air on all the time and it blows a lot of air down into the basement bc I have ducts down there.... As long as I can't die from some fumes I don't care.Sorry, didn't mean to cause panic. I think it all depends on the volume of air you're exhausting.

I just got one of the AC Infinity ones:
For me half the issue is cold air coming 'down' the exhaust line and pushing stink out into the room if the fan isn't running. Had it happen a few times late summer when my T6 shut itself down and it was cool enough to create backdraft at night. I ended up moving to an always on setting but really wanted to utilize the auto functions to keep my tent temperature regulated to a narrow temperature band with lights on and for when lights out hit and the humidity rises to keep it in reasonable check.Change in seasons here. First winter with a tent. First winter to be able to remotely monitor temp and humidity. Currently no exhaust fan needed and maintaining ~80f during lights on, 70f off with the tent. Had a backdraft flap on the exhaust fan but with the fan never running decided the natural flow of air would be better rather that stave them for CO2 or high humidity stagnate air.
I used to vent directly into my cold air return for my furnace. It worked great the whole time I lived at that house(6years). I always wanted to tap into one of the ducts on the output side or the furnace too so my room would be heated and cooled the same as the rest of the house. Those vents were harder to get to in my basement and I would have had to run ducts across the whole thing though so it never happened.Basement gets hot in the summer, I basically have to have central air on all day (when AC is on air gets into basement with 3 vents off the furnace). My friend/hvac guy said I could take the warm air from the exhaust of the tents and instead of the hot air just getting thrown back into the basement he said it could go back into the furnace with extentsions of the ducting off the tent directly into the furnace? Does anyone do this?? .... In the winter I need the warm air down there bc my basement will get down to 67 degrees so I would just un-hook it then let the air kick into the basement.
Using one of these. I've done it and just used a Y-splitter to vent out the same duct as my exhaust. It worked but wasn't ideal and took up a lot of room in a 4x4. I only did it for one summer. I just shut down indoors and grow outdoor plants in the summer now.How do you put an AC unit in a tent ??
