Look into an inter room vent fan. AC Infinity has them and Vevor has numerous pieces you can saw an 8″ hole and shove the assembly into it and it will give you a “return” of sorts. Dong forget that the air you exchange will be splendiferously odiferous, that can mess up holiday dinner plans during flower.

Thanks !! It’s a stand alone insulated shed of sorts that I have my tent it, but I dig this thing. I think I just need to put a window it to vent out of.

Not all Cultivars are super loud also, I grow in a closet with 2 fans and while sometimes I get a whiff of my plants from my bedroom they smell of sweet citrus and my neighbors say they can’t even smell my grow through the paper thin walls to their bedroom. While the windows *can* open its winter and I currently do not have them open so there is no ventilation in my place at all currently.

I do however have a standing floor fan and a table/desk tower fan providing air circulation. Air circulation is what is important to prevent stagnant hotspots in both your lung room and grow space. So consider what cultivar you want to grow and if it smells super strong, If it doesn’t then you might be good without ventilation but you should have something cleaning your air to prevent spreading spores around if they exist.

I recognize I need to build my own room scrubber in the future to prevent such things in my grow!

Cool. Thanks man. It’s fine for now but I think I need a window to vent to the outside eventually – during late flower. Good to know I could swing it if worst comes to worse and I can just put fans all around. The room has a leaky door so fresh air does come in. And I have room fans set up already. And tent fans of course. So far I’m in week 4 of veg and plants are looking great. I have a x Hale bag for extra CO2. Can’t get my tent temp above 70 yet though.

My tent is in my bedroom, and vents into it. I sleep in there with my door closed my CO2 goes up to 6 or 7 hun dred overnight. My inline fan runs on level one continually and goes up to level 3 when paremeters are reached. CO2 is the last thing on my mind. I focus on temps and hunidity. During veg I go 82degrees at 60%. During flower I go 75 degrees at 50%.

Thanks for the info !

If you have central air you’ll be fine. Just vent it. Let the air inside circulate and just scrub the air if you really need to. Just keep your temps lower in your lung area.

[whitesagegrower]

Unfortunately I have no central air. Just a leaky door with no windows !

Every situation will be abit different here IMO let’s say you’re growing in a room that has hardwood studs & drywall with 70% humidity year round ?

Mold will be an issue if ventilation is not under control, bigger concerns would be my property damage.

I keep humidity at 50% the whole grow for this reason. Lower temps, not optimal in veg but it works out.

Take it easy growmie !

My room place sits at a very low 10% humidity, I too go on the lower side of the temperatures at 19-21C generally. It shifts outside and I need to adjust the knob’s on the heaters. Keeping the temps low like that lets the plants hit their optimal VPD easily which seemed like the better option than higher temps out of VPD range.

I totally agree that the best option is based on your individual environment.

Not everyone can control the temps in each room during the winter like I can.

[whitesagegrower]

Thanks for the reply. The room is insulated so in the winter I run a space heater and in the summer it stays cool on its own. Mold is not an issue at all. I dehumidify in the summer if it gets too humid. I just don’t know if the room refreshes itself enough for a grow since there are no windows that open. Just a leaky door that lets in fresh air. When the inline fan really starts cranking I’m worried I won’t have enough fresh CO2 coming in.
