Anyone Vent Inside During Winter/Outside During Summer?

I got rid of my tents a while back and am
finally getting a room built. The room is in
a heated walkout basement that can get
pretty damn cold in the winter (if I keep the
thermostat turned way down). It stays fairly
cool during the summer but not as cool as
a non-walkout.

I'm thinking that exhausting into the basement
during the winter will help heat the basement
a bit and the rooms upstairs which will save me
a few bucks on propane (no natural gas out here
and propane ain't cheap).

The main pitfall I could see would be humidity but
I'm in the market for a commercial dehumidifier that
should keep the entire basement in check. If anyone
has some advice on buying a used dehuey please
see my thread:
https://www.rollitup.org/grow-room-design-setup/627477-anything-look-when-buying-used.html

Replies in this thread are welcome since I've received
none in the other thread. I really don't want to drop
around $1k and get a non working unit

For winter I'm thinking of exhausting from the carbon
filter though a hole in the grow room wall into the
basement and in the summer I'll exhaust out of one
of the small basement windows made to not look like
a grow room exhaust

Any thoughts, advice, ideas, or stoner engineering tips

Thanks,

That's what I did. Vent into my bedroom when it was cold so I could turn off heat at night. Kept the room cozy. Now that it's warming up I had to switch it to the attic. I did some research when looking for a used dehumidifier as well and came across some info that said you are better off getting a new one. Don't remember where I found it, but it said there are many problems that can occur with them and you cant tell just by taking a look at it, and their efficiency can decline. Plus a warranty is a + on expensive equipment imo.

Does your basement need heat specifically?
I draw from my heating system returns and exhaust into the main manifold(needs a backflow valve), works great, saves me ~$200/month in heat during the wintertime.

Are you a heating AC guy or is this something any tard (me specifically) can do on their own?

Easy but not easy to do. He intakes air from the cold air returns on the furnace and exhausts his grow room air to the fan side of the furnace. That is why the blow-back valve is necessary, so the furnace does not pump heat into the grow room when the grow room fans are off.

I like that, it is a pretty good idea.

Mostly it is being able to mess around with sheet metal and attaching your fans through the furnace ducting.

In your case, I would recommend this. Your grow room is in the basement, in the winter months, use an air exchange fan to exchange the air from your grow room to the open basement. Then the open basement air gets sucked back into your grow room and keeps the temperatures balanced. I do this between my grow closet and the room the grow closet is in. If you just exchange the air with out exhaust, then I would highly recommend supplementing with CO2.

I vent inside this time of year and it heats my small home , only downfall is running dehumidifiers 24/7 ..

I guess I am lucky, I burn wood for heat, I have to add moisture with steam pots on the wood stoves. Due to the shape of my home, I have two wood burners. The air gets very dry. Static shock city here!!

I do vent a little outside in the winter, but I do also exchange the air. I plan to add CO2 and discontinue venting outside in the winter.

Do you not have the smell from the plants during flower? I vented inside my basement where I used to live. Used a carbon scrubber when exhausting but the whole house would smell during flower (mainly basement but still seeped upstairs). Do you use just one scrubber and that takes everything away for you?
